10 Data Backup Mistakes That Could Ruin Your Day

Not all backups are the same. In fact, you may make a small one, a much larger one, another one simply of certain folders, etc. But whatever the type of backup you are going to make, it is advisable to check some aspects that we are going to show you in order to avoid problems.

Have only one copy

This is a common mistake. We create a security copy of the files we have, and we think it is enough. It is clear that one data backup is better than none at all. However, the ideal is to have at least two. What happens if that backup copy has a problem just when you are going to need it? You would be left without the files.

For example, a good idea is to have two physical disks in different locations. It is also interesting to have a physical copy and another in the cloud. The idea is to have an alternative in case one fails. This way it will not happen that you have lost all the content.

Using an unreliable platform

By this we mean the use of the cloud. There are many options on the Internet. However, not all of them are reliable. You could be using an insecure service that does not use good encryption. That means your files could be at risk. As a result, your backup could be exposed to anyone.

What you should do is to check very well which platform you use. Some like Google Drive or Dropbox are very popular and work well, but there are more. You can read reviews and ratings, to analyze if it is really reliable or not.

Not having a copy plan

It is a good idea to plan well when to create backups: Once a day? Once a week? This decision will depend on each case. However, you should at least have an idea so that you don’t spend too much time. So making such a backup can save your files from being lost forever in case something happens.

Logically, the more frequently you make these copies, the better. The less likely you are to lose a file before you have backed it up to your hard drive or the cloud platform you use.

Do not look at safety

Security is key. We come back to the same thing: beware of cloud platforms that do not meet minimum security standards. Avoid using pages that you find and that you have not checked well. You don’t really know if your files are going to be properly protected. Moreover, in case of a vulnerability you could have problems.

Therefore, always check the security very well. Type of encryption, that the applications are up-to-date, the way in which you can share the files with third parties, etc. Everything can have an influence.

Poor quality storage appliances

In this case, we are talking about physical disks where we can save the copies. Having one of poor quality can be a major problem. Do not buy a cheap one without really knowing what it is like. It could work well today. However, in a few months or a few years it may stop working, and you may lose everything you have stored.

A clear example is memory cards. In many cases, these cards are of very poor quality and do not have a long life span. The same can also happen with larger hard disks.

Small space

Backup copies will require more or less space, depending on what you need. It is not the same to create a data backup of just text documents, as it is to create a backup of the entire cell phone. Or the entire computer where you have many files of all kinds stored.

Think carefully about what space you need and choose a platform that suits your needs. If you are going to buy a hard disk, do not fall short. It is possible that today 1 TB is enough, for example, but maybe in 1 or 2 years you will need 2. Better to buy a 2 TB disk first and not have space problems soon.

Do not automate copies

Automating backups is interesting, and a mistake is not taking this option into account. For example, you may have a NAS server that allows you to schedule a backup every day at a certain time. Also, the new photos that you have on your cell phone can be copied directly when you connect to Wi-Fi.

This prevents you from forgetting to make copies. There is nothing better than uploading files automatically or shortly after creating or modifying them. You will always have up-to-date backups available.

Having little information on the data backup

This mistake may be related to others we have seen before. Basically, it is to hire a cloud service or buy a hard drive, but without having much information. Ideally, you should be well-informed, read reviews and reports from other people who have previously used it.

Once you have all the necessary information, then proceed to use that service to create your backups. You will avoid using one that does not work properly in the future and with which you may have problems.

Using something obsolete

This can happen both when using the cloud, and when buying a physical hard drive. Beware of this. In effect, it could mean that it stops working properly, that you don’t receive updates, or that you have general problems when using it. It is always best to use something that is currently supported and not obsolete.

In the case of hard drives, avoid buying a very old model, even if you see that it is cheap. It is better to opt for a more recent one. This allows you to both secure and improve performance when you are going to save files.

Sharing with the wrong people

Yes, this is another mistake when it comes to using the cloud and having backups. Maybe you decide to share something with someone else and what you do is upload everything to the cloud. The problem is that not only could that person misuse what you share, but they could attack your account and get to your files.

Therefore, it is advisable to limit who you share files with on the Internet. Always check who you are giving permissions to. Also limit those permissions to only certain files and change them once they have downloaded the content.

As you can see, there are certain mistakes to avoid when creating data backups. This can affect whether you use the cloud, as if you save the content physically. Always check everything very well, and you will not have problems impacting your files.

Why limit Internet speed on Windows

You may wonder why this option might be useful. Think about a limited Internet tariff. For example, if you are sharing data from your mobile to your computer. Consequently, you are going to have some gigabytes available. In addition, if you use a program that consumes many resources, such as the browser, you could use up that data in a short time.

But mainly this will be interesting when we have a limited connection in terms of speed. For example, if we connect to a Wi-Fi that is fragile. Furthermore, if we have a contracted connection with a very limited bandwidth. Therefore, when using some applications, we can exhaust the bandwidth. For example, streaming videos in high definition or downloading.

That could cause problems if we connect to another computer at the same time. We would not have enough bandwidth to perform certain tasks. For example, we could make a video call without any interruptions or open a web page. In these cases, it can be fascinating to set a limit to the Internet speed and thus avoid consuming resources.

This limit can be set for a specific application. In addition, you will be able to set a limit to the download speed, but also to the upload speed. You will be able to set what you are most interested in at that given moment. So, you can avoid issues that may affect your connection. In any case, you will be able to remove it, and it will consume again all that the program needs.

Steps to limit download and upload speed on Windows.

To limit the download and upload speed on Windows to certain programs, you will have to install additional software. This program is called NetLimiter, it is free and available for Windows. With it, you can set a limit to the download or upload speed at any time.

How to Install NetLimiter

Therefore, the first step to limit the download or upload on Windows is to install NetLimiter. To accomplish this, you have to go to its official website and to the download section. The application will start downloading automatically. Besides, the installation process is simple. It will take more or less time depending on your system. However, it should not take more than a couple of minutes.

Set a limit

Once you have installed it and see the icon appear, you can start it. It will automatically show you a screen with different applications that can consume data. Likewise, it also shows the applications that are currently consuming data. You will see, for example, the web browser. Next to each program, you will see the download and upload rate in real time.

This already gives you an idea of what each program is consuming. If you see that an application has a very high download or upload rate, you can see that it is consuming a lot of bandwidth. For example, if you try to open a YouTube video in the browser, you will see that the download rate automatically increases.

How can you set a limit? It is basic. To complete this, you just have to click on the program you are interested in, let’s say the web browser. It will automatically show you a series of options on the right-hand side. The one you are interested in is the Limit, which you can select both download and upload. Click on Not set and a bar will be displayed to set what you are interested in.

There you can set the limit you are interested in. You will be able to do it both upstream and downstream. Moreover, you can do it in a single program as well as in any other program you want. For example, if you want to give a limit of 300 KBps, you just have to put it in the box. Finally, click on OK to apply the changes.

Remove a limit

If at any given moment you would like to remove the limit you have set, all you have to do is click again on the program you are interested in. Then click on Limit and you will see the limit you have previously set, for example those 300 KBps we mentioned. You may have set it in download or upload. You will see that option added, and you only have to click on Delete. From that moment on, the program will connect to the Internet normally. Without considering any download or upload limit.

Prioritizing a program

You may want a program to have a higher priority to use the available resources. For example, if you have a download application, you may want it to download faster and take full advantage of the download speed you have contracted. This is very useful when you do not have a large bandwidth.

What you have to do in this case is to click on the program you are interested in, go to the right side and click on Priority. There you can assign a low, normal, high or critical priority. This will help you to better manage the available resources of that computer.

In short, following these steps we have shown, you will be able to use NetLimiter to set a limit on the download or upload speed on Windows. If you have some programs that you don’t want to use up your bandwidth, then this is for you. All right, that’s all for now. See you soon!

Google Drive

Every Android smartphone user requires a Gmail account. Beyond that, a Gmail account and Google services are widely used. Consequently, you enjoy a basic cloud storage plan with Google Drive with 15 GB of free storage.

This service works as our own virtual hard disk. Indeed, we will be able to host files, those files, or folders, with no size limitation. However, we can also share them with users to whom you share the link, or select manually those who will be the recipients of the file.

OneDrive

Microsoft’s storage solution is also free of charge. In fact, all you need is a Hotmail, Live account or any of the Redmond e-mail formats. By the way, Xbox accounts are also included.

In this case, we will be given 5 GB of free storage by default. However, there are special payment plans to increase that capacity.

Dropbox

The third major cloud service is Dropbox, which has been accompanying us and saving files for more than a decade.

Just sign up for an account with 2 GB of free storage. From now on, start sharing photos, documents and all kinds of files from any device.

Mega

By creating a Mega account, you will have access to 20 GB of free online storage. It’s certainly a great help for file storage problems.

If that’s not enough for you, they have MEGA Business payment rates, from 3 TB for 15 euros per month for 3 users… up to 10 PB (petabytes) for 25,007.50 euros per month.

WeTransfer

WeTransfer is one of the most widely used websites, especially at the professional level. Indeed, it is very useful to upload files and share them with your recipients in a few steps. The difference is that it is not a cloud hosting service and uploaded files expire after 7 days.

One of the advantages of WeTransfer is that it is free of charge, and you do not need to be registered to receive or send files. However, files must be 2 GB or smaller for the system to process them.

Smash

Although it is much less well known than Wetransfer, Smash offers a big advantage over it. The difference is that there is no limitation on the maximum file size.

Beyond this positive difference, the operation is similar. It is sufficient to choose an e-mail address to which the file download link is sent. On the other hand, allowing us to be the ones to copy and paste it to those people who are going to download it.

TransfeNow

Another WeTransfer-style alternative for uploading your files. Worth a look. In its free version, it allows you to send files up to 4 GB without registration.

You can email the files to your contacts or get a customizable sharing link. This way, the mechanism has a more secure and private look and feel. Very well, in this way we have seen 7 free websites for uploading files to the Internet. Bye!

As we already know since Oracle took over MySQL many Linux distributions, they took it out of their official repositories. This resulted in the incorporation of a fork called MariaDB. In terms of compatibility everything is guaranteed but it is true that many developers still prefer to use MySQL. So, you have to use another repository for it.

Install MySQL on Fedora 34/33

Oracle provides us with a repository to install MySQL. Specifically, version 8.0 is loaded with interesting new features. So, the first step is to open a terminal session and execute the following command to add the MySQL repository.

For Fedora 34

:~$ sudo dnf install https://dev.mysql.com/get/mysql80-community-release-fc34-1.noarch.rpm

For Fedora 33:

:~$ sudo dnf install https://dev.mysql.com/get/mysql80-community-release-fc33-1.noarch.rpm

Then, once the repository is correctly added, we can install MySQL with the following command:

:~$ sudo dnf install mysql-community-server

And already, but before using it you have to make a few small configurations.

Using MySQL

MySQL is already installed, but you have to start the service to use it. So, run this command:

:~$ sudo systemctl start mysqld

If you want MySQL to start along with the system, use this other command as well:

:~$ sudo systemctl enable mysqld

For security reasons, MySQL generates a temporary root key. Please note that MySQL has even stricter security policies than MariaDB.

Then, you have to show which is the temporary password generated to be able to run the mysql_secure_installation script and be able to set a definite root key.

To do this, use the following command:

:~$ sudo cat /var/log/mysqld.log

In the image you can see, the generated key. Remember that in each case, it is different.

Then we can use the mysql_secure_installation script. In this script we will be able to set the definitive root password and make other security settings for the server.

:~$ sudo mysql_secure_installation

Enter the temporary key you previously obtained and you will immediately be able to establish yours.

MySQL has a plugin that does not allow weak passwords, so it establishes a strong one with numbers, signs and combinations of lower and uppercase letters.

Then, answer the security questions as you prefer. I said yes to all of them.

Now, you can use MySQL without problems. To do this, access the console with this command:

:~$ sudo mysql -u root -p

So, enjoy it.

Conclusion

MySQL continues to be the reference of the database relations handlers in Linux. However, as it is not present in the official repositories of Linux distributions, you have to take extra steps to install it.

It is becoming more and more common to read and hear about security breaches from companies that handle vital user information on the Internet, and this makes many people wonder whether it is so necessary to trust these giant companies.

Another important issue is that these large companies do not take the issue of privacy seriously and their handling of user files and information is at least questionable.

Therefore, many users and small businesses prefer to invest in infrastructure that allows them to have their private cloud. At the software level, owncloud is emerging as the most important solution in this matter.

OwnCloud is a software that allows us to create a private cloud with which you can synchronize files, calendars, contacts, notes and more using extensions. It’s free, open-source and has an application for Android, iOS and desktop clients for Linux, Windows and Mac OS X.

So, let us install it.

Owncloud on Ubuntu 18.04

1.- Install LAMP on Ubuntu 18.04

The first step is to install a LAMP server on Ubuntu 18.04. But don’t worry that we have an article with which you can do it without problems.

How to install LAMP on Ubuntu 18.04?

Then, you can continue with the rest of the steps.

2.- Install some PHP module and create the new database for Owncloud

Owncloud, in order to work properly, requires some extra PHP modules. So let’s install them first.

:~$ sudo apt install libapache2-mod-php7.2 openssl php-imagick php7.2-common php7.2-curl php7.2-gd php7.2-imap php7.2-intl php7.2-json php7.2-ldap php7.2-mbstring php7.2-mysql php7.2-pgsql php-smbclient php-ssh2 php7.2-sqlite3 php7.2-xml php7.2-zip

After installing LAMP, it is possible that several have already been installed, but better to be sure.

After that, create a new user and database for Owncloud.

:~$ sudo mysql -u root -p
> CREATE DATABASE owncloud;
> GRANT ALL PRIVILEGES ON owncloud.* TO owncloud@localhost IDENTIFIED BY 'owncloud_password';
> FLUSH PRIVILEGES;
> exit;

Of course, you can modify the name of the database, the user name and the password for one that you prefer.

Now, we can start to install Owncloud.

3.- Install Owncloud on Ubuntu 18.04 (I)

We can choose two ways to install Owncloud. One is to download the package directly from the project website. But the other is easier and safer and is to do it from the Owncloud repositories.

To do this, first, you need to install a necessary package.

:~$ sudo apt-get install apt-transport-https

Then, we have to add the GPG key of the repository to be sure that the download and installation will be safe.

:~$ sudo wget -qO- https://download.owncloud.org/download/repositories/stable/Ubuntu_18.04/Release.key | sudo apt-key add -
OK

Now we can add the repository as such. The next command, you have to do it as the root user, so execute:

:~$ sudo -i

And then:

:~$ echo 'deb http://download.owncloud.org/download/repositories/10.3.2/general/Ubuntu_18.04/ /' > /etc/apt/sources.list.d/owncloud.list

Returns to a regular user:

:~# exit

All that’s left is to refresh the APT cache and install Owncloud.

:~$ sudo apt update && sudo apt install owncloud-files

Wait for the download to finish in installation.

For everything to go well, you must enable two Apache modules that are not by default.

:~$ sudo a2enmod rewrite
:~$ sudo a2enmod headers

And create a new configuration file for Owncloud.

:~$ sudo nano /etc/apache2/conf-available/owncloud.conf

And add the following content:

ServerName owncloud.osradar.test
Alias /owncloud "/var/www/owncloud/"

<Directory /owncloud "/var/www/html/owncloud">
  Options +FollowSymlinks
  AllowOverride All
  <IfModule mod_dav.c> 
      Dav off
  </IfModule>

 SetEnv HOME /var/www/owncloud
 SetEnv HTTP_HOME /var/www/owncloud
</Directory>
 
 

So, press CTRL + O to save the changes and CTRL + X to close the file.

Finally, enable the new configuration and restart Apache2.

:~$ sudo a2enconf owncloud
:~$ sudo systemctl reload apache2

Now we can complete the installation from the web browser.

4.- Install Owncloud on Ubuntu 18.04 (II)

Now, you can open your web browser and go to http://your-server/owncloud and you will see the following:

There, you will have to set up the administrator user account. Below on the “Storage & Database” section select MySQL / MariaDB and fill in the fields with the created MariaDB credentials.

Then, it will start the Owncloud installation and configuration on the server. Then you will see the Login screen where you will have to enter your credentials.

Then you’ll see this screen. This shows that everything is in order.

So, that is it.

Conclusion

Owncloud is quite useful to be able to have our own private cloud without depending on third parties. However, you have to know how to install it and thanks to this guide you know how to do it. All that’s left is for you to do it and get the most out of this tool.

The post How to install Owncloud on Ubuntu 18.04? appeared first on Linux Windows and android Tutorials.

Briefly, I will tell you that Docker compose is more thought of production environments where compatibility should be as high as possible. This is precisely the great advantage of Docker images that we will be able to use in any supported system thanks to the technology of containers. Then, these steps can be done from any Linux distribution that has installed Docker and Docker Compose.

Owncloud is one of the best-known solutions to create our own private cloud as if it were a professional service. Of course, by this I do not mean that Owncloud is not professional, I mean that its behavior is similar to that of proprietary solutions such as Google Drive or OneDrive.

So let’s get to work.

Install Docker and Docker Compose on Linux

The first step is to have Docker installed in the system, obviously.

• If you are using Ubuntu: How to install Docker on Ubuntu 18.04?
• For CentOS 8: How to install Docker on CentOS 8?
• For CentOS 7: How to install Docker CE on CentOS 7?
• If you use Windows: How to install Docker in Windows 10?
• Or, if you are using Debian 10: How to install Docker on Debian 10?

And using your distribution’s package manager, you can install Docker Compose. For example:

:~$ sudo apt docker-compose

For Debian, Ubuntu, and derivatives.

:~$ sudo dnf install docker-compose

Or, for RHEL, CentOS and derivatives.

Deploy Owncloud using Docker compose

Well, the first step is to create a new folder where we will do the process.

:~$ mkdir owncloud
:~$ cd owncloud

Then, in that folder create a new file called docker-compose.yml that contains all the instructions for deployment. When you create it, add the following:

:~$ sudo nano docker-compose.yml

version: '3.1'

services:

  owncloud:
    image: owncloud
    restart: always
    ports:
      - 1234:80
    volumes:
      - /home/angelo/owncloud_data:/var/www/html
      - /home/angelo/owncloud_data/apps:/var/www/html/apps
      - /home/angelo/owncloud_data/config:/var/www/html/config
      - /home/angelo/owncloud_data/data:/var/www/html/data

  db:
    image: mariadb
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: angelo123

I proceed to explain.

In this file, we will raise two services. The first is the Owncloud. The image is configured for Owncloud to run on port 80, but I exposed port 1234. You can set the number you want but don’t touch 80.

Then come the volumes. The first part is folders on our host system to make sure the data is persistent. These folders must be created before the services are deployed.

After this, comes the second service. By default, the Owncloud image is configured to use SQLite. But in this case, we have decided to use MariaDB. All simple just set up an initial key and you’re done.

Let us create the volume folders.

:~$ mkdir /home/angelo/owncloud_data
:~$ mkdir /home/angelo/owncloud_data/apps
:~$ mkdir /home/angelo/owncloud_data/config
:~$ mkdir /home/angelo/owncloud_data/data

Then, run Docker Compose.

:~$ sudo docker-compose up -d

That’s enough. Now open your web browser and go to http://your-server:1234 and you will see the following. Create an admin account.

Next, configure the Database.

Finally, you’ll see the login screen and you are done. You can now use Owncloud.

Conclusion

Owncloud is a really useful application. And to deploy it using Docker compose is something easy and within everyone’s reach.

For more information on this, see the official documentation of the Owncloud Docker image.

MariaDB is a well-known archi Database Relationships Management System that is a MySQL fork. This is due to the purchase of Sun Mycrosystem by Oracle. It is perfectly compatible with MySQL and is available in most Linux distributions.

In Ubuntu 18.04 LTS the version of MariaDB that is available in the official repositories is 10.1, but recently has seen the release of version 10.4 with some interesting new features. Some of them are:

• The unix_socket authentication plugin is now default on Unix-like systems. This represents a considerable improvement in authentication security.
• The obsolete mysql.host table is no longer created
• User password expiry. This forces you to change it periodically.
• User accounts and global privileges are now stored in the mysql.global_priv table.

And many other news related to the creation of cLuster and Galera 4. If you want to know them, I recommend you to read the changes and improvements of version 10.4.

So, using this version on our Ubuntu 18.04 is a good idea.

Installing MariaDB 10.4 on Ubuntu 18.04

The first step is to install some necessary packages. So open a new terminal session and run the following command:

:~$ sudo apt-get install software-properties-common

The easiest way to install MariaDB on Ubuntu 18.04 is through the application repositories. To do this you have to add the GPG key of the repositories:

:~$ sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8

At the end, we will be able to add the repository itself.

:~$ sudo add-apt-repository 'deb [arch=amd64,arm64,ppc64el] http://nyc2.mirrors.digitalocean.com/mariadb/repo/10.4/ubuntu bionic main'.

Next, the APT cache needs to be refreshed to recognize the new repository:

:~$ sudo apt update

Now, we can install MariaDB 10.4. To do this, use the following command:

:~$ sudo apt install mariadb-server

If you have it installed, just update the distribution:

:~$ sudo apt upgrade

With MariaDB installed, the first step is to define a root password and secure the installation:

:~$ sudo mysql_secure_installation

And finally check the installed version:

:~$ mysql --version

Now you can work with MariaDB. That is it.

Conclusion

MariaDB 10.4 is a good improvement over previous versions. But it is not always available in the official repositories of other Linux distributions. Today you have learned how to install it in Ubuntu 18.04.

OrientDB is an open source NoSQL database management system written in Java. One of its main features is that it is not only NoSQL based but also very fast. Especially in large projects where performance is indispensable.

Of course, an application of OrientDB quality is expected to have an enterprise version, aimed at companies and that is not free; however, we also have a community version.

For this tutorial we will use the community version. I recommend you to visit the OrientDB website to read all its features.

So, let us start.

Getting OrientDB on Debian 10

1) Install Java on Debian 10

The first step is to install Java. This is because OrientDB is an application created with Java. So we need the Java JRE. You can use the Oracle version or the official repositories version.

Then, open a terminal session and run the following:

:~$ sudo apt install openjdk-11-jre

After finishing the installation, check the installed version:

:~$ java -version
openjdk version "11.0.5" 2019-10-15
OpenJDK Runtime Environment (build 11.0.5+10-post-Debian-1deb10u1)
OpenJDK 64-Bit Server VM (build 11.0.5+10-post-Debian-1deb10u1, mixed mode, sharing)

So, everything is OK. We can continue.

2) Install OrientDB on Debian 10

Now it is OrientDB’s turn. To do this, we will first have to download its binaries from the project’s website. Remember that we are using the community version.

:~$ cd /tmp/
:~$ wget -c https://s3.us-east-2.amazonaws.com/orientdb3/releases/3.0.24/orientdb-3.0.24.tar.gz

After this, unzip the file and move the folder to /opt/orientdb

:~$ tar xvf orientdb-3.0.24.tar.gz
:~$ sudo mv orientdb-3.0.24 /opt/orientdb

For security reasons, it is advisable to create a new user for OrientDB. On top of that, you have to give it ownership of the folder.

:~$ sudo groupadd -r orientdb
:~$ sudo useradd --system -g orientdb orientdb
:~$ sudo chown -R orientdb:orientdb /opt/orientdb

Now we can get the server up and running. To do this, access the /opt/orientdb/bin/ folder and run the server.sh file.

:~$ cd /opt/orientdb/bin/
:~$ sudo ./server.sh

If this is your first time running the server, you will need to define a root key. When you write and confirm it, OrientDB will start.

Now you can open your web browser to access the graphical interface provided by the application. You can access it from the following address http://IP_SERVER:2480/studio/index.html. Remember that port must be open in the Firewall.

So, type your credentials. The user is root and the password what you defined before.

Next, click on the connect button. And you can start to work with OrientDB.

So, that is it.

Conclusion

There are many applications that can store data. These applications known as database management systems are vital for application development. Well, OrientDB focuses a lot on the professional and large scale but we will always be able to use it in our projects because we just learned how to install it.

MyWebSQL is an open-source tool to manage data stored in MySQL or MariaDB. However, it is not only limited to them but is compatible with PostgreSQL and SQLite. Therefore, we are in the presence of an essential tool on the client-side.

So, let us install MyWebSQL on Debian 10.

Install MyWebSQL on Debian 10

1) Upgrade your system

The first step is, of course, to update the system. With this, we will be able to have the security patches correctly installed.

So open a terminal session and run the following:

:~$ sudo apt update
:~$ sudo apt upgrade

That way the system will be a little safer and we will be ready to go.

2) Install LAMP on Debian 10

MyWebSQL is a web application that needs a server to run. So you can deploy a LAMP server for it.

Read, How to install LAMP on Debian 10?

After everything is in place, we can continue.

3) Create a new user on MariaDB

When we use web tools to manage MySQL or MariaDB, it is best to create a new user. And to this new user, give permissions on the rest of the databases and tables.

So let’s go for it:

:~$ sudo mysql -u root -p
> USE mysql;
> CREATE USER 'angelo'@'localhost' IDENTIFIED BY 'Angelo12.,';
> GRANT ALL PRIVILEGES ON . TO 'angelo'@'localhost';

Now we can install MyWebSQL without problems.

4) Installing MyWebSQL on Debian 10

Unfortunately, there is no DEB package for Debian. However, the installation is quite simple. Just download the application files into the Apache folder.

First, download it:

:~$ wget https://newcontinuum.dl.sourceforge.net/project/mywebsql/stable/mywebsql-3.7.zip

Then, we proceed to decompress it in the root folder of Apache.

:~$ sudo unzip mywebsql-3.7.zip -d /var/www/html

In the end, we only need to grant the necessary permissions for the application to run correctly:

:~$ sudo chown -R www-data:www-data /var/www/html/mywebsql/
~$ sudo chmod -R 775 /var/www/html/mywebsql/

That’s enough. Now let’s try it.

Now, open your favorite web browser and go to the following address http://your-server/mywebsql/install.php to verify that everything is in order.

As everything is in order, you can log in on http://your-server/mywebsql/ and delete the installation file.

:~$ sudo rm /var/www/html/mywebsql/install.php

Now, type in your MariaDB credentials. And you can start to work.

So, enjoy it.

Conclusion

Managing a lot of data in MySQL or MariaDB is not so easy to do in a terminal. So these tools are always welcome to help us with the task. Today, you have learned to install MyWebSQL on Debian 10 and as you can see the process is quite simple.

Install Docker and Docker Compose on Linux

The first step is to have Docker installed in the system, obviously.

• If you are using Ubuntu: How to install Docker on Ubuntu 18.04?
• For CentOS 8: How to install Docker on CentOS 8?
• For CentOS 7: How to install Docker CE on CentOS 7?
• If you use Windows: How to install Docker in Windows 10?
• Or, if you are using Debian 10: How to install Docker on Debian 10?

And using your distribution’s package manager, you can install Docker Compose. For example:

:~$ sudo apt docker-compose

For Debian, Ubuntu and derivatives.

:~$ sudo yum install docker-compose

Or, for RHEL, CentOS and derivatives.

Install Nextcloud using Docker compose

Now that we have our environment ready, let us create a folder called nextcloud and navigate there to then create the docker-compose.yml file.

:~$ mkdir nextcloud && cd nextcloud

Now we will create the file with the following content.

:~$ nano docker-compose.yml

version: '2'
 volumes:
   nextcloud:
   db:
   data:
 services:
   db:
     image: mariadb
     command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
     restart: always
     volumes:
       - db:/var/lib/mysql
     environment:
       - MYSQL_ROOT_PASSWORD=1234osradar
       - MYSQL_PASSWORD=1234osradar
       - MYSQL_DATABASE=nextclouddb
       - MYSQL_USER=nextclouduser
 app:
     image: nextcloud
     ports:
       - 1234:80
     links:
       - db
     volumes:
       - nextcloud:/var/www/html
       - data:/var/www/html/data
     restart: always

Let us remember that this image of Nextcloud is the official one so many of these parameters are unalterable. Although we can always add new configurations.

The explanation can be quite brief because of the explicit variables. In the image of MariaDB, we take the volume db that will be in /var/lib/mysql to preserve the data that Nextcloud stores. On the other hand, in the environment section, there are the parameters of the database, user and password. You can modify this as I did.

In the nextcloud image, we simply redirect the application port through ours. I have chosen as an example the 1234 but you know that you can modify it. And I have added two volumes one for the application as such and another for the data. Remember to create these folders in case you don’t have them already created.

Not much more than explaining the truth.

Once everything is in place, we save the file and close them. Then we run it:

:~$ docker-compose up -d

At this point you can open the browser and go to http://your-server:1234 but we will make a virtual host in Apache to avoid having to use the port. In other words an inverse proxy with Apache.

To do this, enable the following Apache module:

:~$ sudo a2enmod proxy_http
:~$ sudo systemctl restart apache2

Then, create the new virtualhost for Nextcloud:

:~$ sudo nano /etc/apache2/sites-available/nextcloud.conf

And add the following:

<Virtualhost *:80>
     ServerName nextcloud.osradar.test
     <Directory /var/www/html/>
       Options FollowSymlinks
       AllowOverride All
       Require all granted
     </Directory>
     ErrorLog ${APACHE_LOG_DIR}/nextcloud.osradar.test_error.log
     CustomLog ${APACHE_LOG_DIR}/nextcloud.osradar.test_access.log combined
     <Location "/">
         ProxyPass "http://localhost:1234/"
         ProxyPassReverse "http://localhost:1234/" 
     </Location>
</Virtualhost>

Then, save the changes and close the file.

So, enable the new Virtual host.

:~$ sudo ln -s /etc/apache2/sites-available/nextcloud.conf /etc/apache2/sites-enabled/nextcloud.conf
:~$ sudo a2enmod rewrite
:~$ sudo systemctl restart apache2

Complete the installation

Now, open your web browser and you will see the main page. Just type your database credentials and complete the installation.

In this step, I want to stop for a while. On the host, we do not type localhost but we refer to db which is where MariaDB is “installed”. So, the port is 3306 because it is the default and in the docker-compose.yml file we do not specify another one.

Then the installation will begin and you will see the dashboard.

And that is it. You can read more about Docker on the project website. Or about docker compose.

Conclusion

Docker we already know how powerful he is and today we have seen a bit of what can be done. In a few minutes, we can have in our server a Nextcloud instance working without any problem. So let’s make the most of it.
