MongoDB is the most representative of the databases known as NoSQL, an acronym for Not only SQL. It is document-oriented and multi-platform, which means that we can use it on many different systems.

In Mongo DB there are no predefined schemas, the keys and values of a document are of fixed types or sizes, in a document with a fixed schema the tasks to add or delete fields become easier and with great performance.

Data in Mongo DB is stored using BSON format structures, which is a specification similar to JSON so any modern text editor can edit it without any problems.

So MongoDB has positioned itself as one of the most solid alternatives to database managers like SQLite or MariaDB. So, let’s go for it.

Install MongoDB on Debian 11

For this post, we will use the MongoDB repository for Debian 10 which also works for this new Debian version. However, we are still waiting for the MongoDB developers to include Debian 11 in their repositories.

So, open a terminal and update the operating system completely.

sudo apt update
sudo apt upgrade

Before adding the MongoDB repository to the system, it is necessary to install a package called gnupg2.

sudo apt install gnupg2

After that, add the GPG key of the repository as follows

wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -

Now add the MongoDB repository to your system by running

echo "deb http://repo.mongodb.org/apt/debian buster/mongodb-org/5.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list

Refresh APT to accept the new changes

sudo apt update

Next, install MongoDB on Debian 11 by running

sudo apt install mongodb-org
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
The following additional packages will be installed:
  mongodb-database-tools mongodb-mongosh mongodb-org-database mongodb-org-database-tools-extra mongodb-org-mongos mongodb-org-server mongodb-org-shell
  mongodb-org-tools
The following NEW packages will be installed:
  mongodb-database-tools mongodb-mongosh mongodb-org mongodb-org-database mongodb-org-database-tools-extra mongodb-org-mongos mongodb-org-server mongodb-org-shell
  mongodb-org-tools
0 upgraded, 9 newly installed, 0 to remove and 25 not upgraded.
Need to get 147 MB of archives.
After this operation, 464 MB of additional disk space will be used.
Do you want to continue? [Y/n]

After that, you can check the installed version using this command

mongod --version

Output:

db version v5.0.3
Build Info: {
    "version": "5.0.3",
    "gitVersion": "657fea5a61a74d7a79df7aff8e4bcf0bc742b748",

        "distarch": "x86_64",
        "target_arch": "x86_64"
    }
}

Managing the MongoDB service

Once it is installed, you can manage its service just like any other service on the system.

To start MongoDB you have to run

sudo systemctl start mongod

It is usually a good idea to make it start with the system so that it is immediately available.

sudo systemctl enable --now mongod
Created symlink /etc/systemd/system/multi-user.target.wants/mongod.service → /lib/systemd/system/mongod.service.

If you make changes to the MongoDB configuration then you will have to restart it to apply the changes.

sudo systemctl restart mongod

Finally, it is advisable to check the status of the service to see if everything is OK.

sudo systemctl status mongod
● mongod.service - MongoDB Database Server
     Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled)
     Active: active (running) since Sat 2021-10-09 18:51:39 CEST; 25s ago

             └─13759 /usr/bin/mongod --config /etc/mongod.conf

Oct 09 18:51:39 osradar systemd[1]: Started MongoDB Database Server.

Creating a new user for MongoDB

To access the MongoDB shell just run the command command

mongo

And once inside, it is recommended to create a new user different from the root.

use admin
db.createUser(
{
user: "osradar",
pwd: passwordPrompt(),
roles: [ { role: "userAdminAnyDatabase", db: "admin" }, "readWriteAnyDatabase" ]
}
)

Copy and paste the following but change osradar to the name of the user you want.

Then you will have to define a password that has to be secure.

Conclusion

MongoDB is a tool to take into account if we want to develop applications that do not require a SQL database handler. Being open-source we can use it in many different situations with guaranteed performance and efficiency.

MongoDB website

The post How to install MongoDB on Debian 11 appeared first on Linux Windows and android Tutorials.

MongoDB allows your teams to easily organize, use and enrich data – in real time, anywhere. MongoDB is a NoSQL and document-oriented database manager. In short, instead of saving the data in the record as the SQL database, it saves them in documents with BSON format which is a binary representation of JSON.

In the world of unrelated SQL database MongoDB is perhaps the most popular, however, it can be used by very different applications that require a semi-structured data collection. On the other hand, its use in transactional systems is not recommended as MongoDB does not support transactions.

That’s why I’m going to teach you how to install MongoDB on the latest stable versions of Fedora, Fedora 34 / 33.

Install MongoDB on Fedora 33

It is possible to install MongoDB on Fedora 34 / 33 through the RPM packages that can be downloaded and installed from the project’s website.

However, the most efficient method is to install from the official MongoDB repository which helps to integrate the application with the system.

So, for ease of use, install the nano text editor.

sudo dnf install nano

And edit a text file to add the MongoDB repository by adding the following content

sudo nano /etc/yum.repos.d/mongodb.repo

[mongodb-org-4.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/8/mongodb-org/4.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc

Save the changes and close the text editor.

Now you can install MongoDB on Fedora 34 / 33 by running

sudo dnf install mongodb-org

After installation, a new service is created for Fedora 34 / 33.

So, refresh the list of system daemons

sudo systemctl daemon-reload

Now start it up:

sudo systemctl start mongod

And then check the status of the service

sudo systemctl status mongod
● mongod.service - MongoDB Database Server
      Loaded: loaded (/usr/lib/systemd/system/mongod.service; enabled; vendor preset: disabled)
      Active: active (running) since Wed 2021-05-19 23:15:47 CEST; 5s ago

     "version": "4.4.4",
     "gitVersion": "8db30a63db1a9d84bdcad0c83369623f708e0397",

         "distarch": "x86_64",
         "target_arch": "x86_64"
     }
 }

So, enjoy it.

Conclusion

So, MongoDB is a solution that is increasingly being taken into account by many developers worldwide. Its installation in Fedora 34 / 33 is relatively simple.

The post How install MongoDB on Fedora 34 / 33? appeared first on Linux Windows and android Tutorials.

DbGate is a modern database management client that works with both SQL drivers such as MariaDB, MySQL; and with NoSQL such as MongoDB.

We are talking about a Free and open-source application that has been released under the MIT license. This makes that you can use it in many projects of diverse nature.

Another aspect to take into account with DbGate is that it is cross-platform. This means that we can use it on Windows, macOS, and of course Linux. Quite useful to improve possible migrations between operating systems. If you come from Windows, you can also use this application.

With DbGate you can easily:

• Connect to multiple databases, directly or through SSH tunnel. Important in terms of security.
• Browse or edit data in your tables or views, filter by column value. This using a data editor.
• Edit SQL queries with auto-complete suggestions or use query designer.
• Export and import from/to CSV, JSON, or Excel.
• Connect to MongoDB, browse or filter JSON document data.

In addition to this, you can further extend the functionality of the program by adding plugins.

Install DbGate on Linux

In the Linux chaos, we have several options depending on the system you are using. In the case of Debian, Ubuntu and derivatives there is a DEB package that can be downloaded from Github or using the terminal.

wget -c https://github.com/dbgate/dbgate/releases/download/v4.2.0/dbgate-latest.deb

And then install it, using APT.

sudo apt install ./dbgate-latest.deb

Then you can run it from the main menu.

There are also other formats like APPImage that you can run from any other Linux distribution or use the binaries.

Conclusion

Having professional tools for database management is a serious matter that requires some preliminary research. At the moment, DbGate has all the basic features to make it a solid alternative to others on the market. Being OpenSource and including Linux support, it generates more exceptions and is an option to take into account.

Enjoy it!

The post DbGate: The Smartest (no)SQL Database Client appeared first on Linux Windows and android Tutorials.

Nowadays many projects are developed using SQL type databases, but it’s more and more common to see NoSQL type databases becoming more and more important. From this type of database, MongoDB stands out a lot.

MongoDB is one of the most popular NoSQL database managers in the world. Unlike managers like MySQL or PostgreSQL, it saves your records in documents so they are more understandable and operations faster to do. As I said, it is incredibly popular with developers.

So let’s get to work.

Install MongoDB on Debian 10

MongoDB has a special repository for Debian 10 that has recently been updated. This will help us to have the latest version available and keep it updated using APT.

So, open a terminal or connect to your server using SSH.

Then, install gnupg which is a package that is necessary to add the MongoDB repository.

:~$ sudo apt install gnupg
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following additional packages will be installed:

Suggested packages:
  pinentry-gnome3 tor parcimonie xloadimage scdaemon pinentry-doc
The following NEW packages will be installed:
  dirmngr gnupg gnupg-l10n gnupg-utils gpg gpg-agent gpg-wks-client gpg-wks-server gpgconf gpgsm libassuan0 libksba8 libnpth0 pinentry-curses

Need to get 7089 kB of archives.
After this operation, 14.9 MB of additional disk space will be used.
Do you want to continue? [Y/n]

Once the program is installed, we can import the GPG key from the MongoDB repository. To do this, use the following command:

:~$ wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | sudo apt-key add -

Once the GPG key is added, you can add the MongoDB repository itself. This is done by running the following command:

:~$ echo "deb http://repo.mongodb.org/apt/debian buster/mongodb-org/4.2 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list

Aftert that, refresh APT software sources.

:~$ sudo apt update

Finally, install MongoDB on Debian 10 using this command:

:~$ sudo apt install mongodb-org
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following additional packages will be installed:
  libcurl4 mongodb-org-mongos mongodb-org-server mongodb-org-shell mongodb-org-tools
The following NEW packages will be installed:
  libcurl4 mongodb-org mongodb-org-mongos mongodb-org-server mongodb-org-shell mongodb-org-tools
0 upgraded, 6 newly installed, 0 to remove and 51 not upgraded.
Need to get 97.7 MB of archives.
After this operation, 295 MB of additional disk space will be used.
Do you want to continue? [Y/n]

Now we work a little with the application.

Using MongoDB

First, you have to start the MongoDB service. Because at this point, the program is installed but not running. To do this, run the following command:

:~$ sudo systemctl start mongod

Once it’s started, you can check the status of the service:

:~$ sudo systemctl status mongod
● mongod.service - MongoDB Database Server
   Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)
   Active: active (running) since Fri 2020-03-06 07:34:05 EST; 22s ago
     Docs: https://docs.mongodb.org/manual
 Main PID: 1882 (mongod)
   Memory: 82.3M
   CGroup: /system.slice/mongod.service
           └─1882 /usr/bin/mongod --config /etc/mongod.conf
Mar 06 07:34:05 osradar systemd[1]: Started MongoDB Database Server.

It’s best to get MongoDB started with the system:

:~$ sudo systemctl enable mongod

Now we can really use it.

Once MongoDB is running, we have to access the shell where we work most of the time. You access it with the following command:

:~$ mongo
MongoDB shell version v4.2.3
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).

The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
---

>

Once inside the shell, the first thing we have to do is create a new database which is where you will work.

To do this there is no create command but use that serves to switch between databases. If the database does not exist, it will be created automatically.

:~$ use Example

You can check existing databases with the following command:

> db
Example

And then, create the user who will own the database.

> db.createUser(
... {
... user: "angelo",
... pwd: "1234",
... roles: ["dbOwner"]
... }
... 
... )

Remember to replace “1234” with a much stronger and more secure password. Just like the user can call himself as you want.

The main advantage of this is that we can now access MongoDB by setting a password and over a database. This increases privacy and security.

Now log out using:

> exit

And now we’re going to prove what we’ve done.

To connect to the database with the newly created username and password, you can use the following command:

:~$ mongo -u [user] -p [pwd] 127.0.0.1:27017/[database]

Do not forget to replace the fields with your assigned values.

So, you can start with MongoDB.

Conclusion

MongoDB is a solid alternative to SQL databases. It is quite popular and is used in many mobile and mass deployment projects. Today you have learned to install it on Debian 10 using the official repository they provide.

Please share this post and join our Telegram channel.

TablePlus is a modern intuitive application that is for managing relational and non-relational databases. Its main advantage is that it is compatible with many database management systems including popular, MySQL, MariaDB, PostgreSQL or SQLite. But it also supports NoSQL databases such as Apache Cassandra and MongoDB. In addition, the team of developers promises that more will come.

I like the minimalist and modern design of the application that gives a sensation of being an application according to these times. However, the application is not free and you have to pay to use it.

On the other hand, the application has stable and consolidated versions for Windows and macOS but recently they have published an Alpha version for Linux. And the best thing is that these alphas are free and we will be able to try them.

So, let’s take a look.

Install TablePlus on Ubuntu

To install it in Ubuntu 18.04, you have to add the application repository. First, you have to add the GPG key to it.

:~$ wget -O - -q http://deb.tableplus.com/apt.tableplus.com.gpg.key | sudo apt-key add - 

Then, add the repository by creating a file called tableplus.list in /etc/apt/sources.list.d/ and add the following:

:~$ sudo nano /etc/apt/sources.list.d/tableplus.list

deb [arch=amd64] https://deb.tableplus.com/debian tableplus main

Save the changes and close the editor. I use the terminal a lot but you can create the file with another editor like gedit.

After that, refresh the APT cache and finally install Tableplus.

:~$ sudo apt update 
:~$ sudo apt install tableplus

Then, you can run it from the main menu.

A little look to this tool for Database management

As soon as you open it you will be able to configure a new connection to a database server. There you will have to configure the connection. You will also have the option to test the connection before starting it.

In my case, I have used an instance of MariaDB to test. By default, when you establish the connection, you see the following way:

On the left side, the list of tables and below you can switch between databases. If you select a table, the data will be shown like this:

As we can see, everything is very clean, tidy, modern. One of the characteristics of this client is that everything looks very integrated with the GTK system. I haven’t tried it with QT.

Thanks to the lower buttons, you will be able to verify the structure of the table very quickly.

Also, you can limit the number of results you get.

So this is a very small look at this application.

Remember it’s an alpha and the developers say there will be weekly updates so don’t forget to update your equipment.

Also, keep in mind that the application will gradually evolve but it is a good start. It has been fast, efficient and easy to use all this with a pretty nice interface.

For more information, I recommend you visit the application website.

So, that is it. Do not forget to share.

Downloading the MongoDB binary for Windows.

The first thing we have to do is, go to the official MongoDB website. Go to the download section and select the MSI file, corresponding to Windows in its current version. At the time of publication of this post, the version is 4.2.1.

Once you have downloaded the file, please run it to start the installation. Press Next to start the installation

Then accept the license and click Next to continue

In the next screen select between a Custom or a complete installation. In this case, I select a full installation.

This next screen is very important since we are going to install MongoDB as a Windows service. In other words, always start with the system and be registered. Also, select the directory where the data will be stored. In addition, select the directory where the logs will be stored. Likewise, you can assign the name for the service. Please remember the installation path. You will probably need it later.

Next, the wizard will ask if you want to install MongoDB Compass. This is a graphical interface to manage the data. If you like it, check the box and click Next to continue.

Once you have selected all the installation options, press Install to start the process.

The wizard will start the database installation process.

After a few minutes, the process will be successfully completed.

MongoDB finally installed

If you installed MongoDB Compass Comunity, then you are ready to use the database. This will start automatically once the installation is finished. Press connect to start the database

Then create the database. Assign a name to the collection as well. Press create database to continue.

It is now correctly configured and ready to be used.

Using MongoDB on the terminal

It is also possible to use MongoDB through command. You have to make some preparations, but don’t worry, here we show you how to do it. The first thing we need to do is check if MongoDB was installed as a service, and it’s running. With this in mind please press the Win+R combination and in the box type services.msc

Next, place Mongo Server in the list of services. Please verify that it is Running and that its Startup Type is Automatic.

It then adds an environment variable to run the service on any Command Prompt. To find out how to do it, please check our post about Wget in Windows 10. Here I only show you the final result. Keep in mind that you have to write the installation path that you assigned previously.

To test the operation of MongoDB, please open a cmd and type Mongo.

Conclusion

Finally we have seen how to install MongoDB in Windows 10. The process has been detailed in a simple way. In addition, we have seen how to start the program in graphical mode and through commands as well. All right, that’s it for now. Greetings!

The post How to install MongoDB in Windows 10 appeared first on Linux Windows and android Tutorials.

As is well known by many, MongoDB is a NoSQL database management system that is very popular in mobile programming. It is quite fast, allows high performance clustering and was a paradigm shift to traditional databases. For this reason, many developers consider it vital for their projects.

CentOS 8 has just come out and it seems that they still do not give it full support from MongoDB. Something strange, because RHEL 8, which is the base of CentOS 8, was released a few months ago, which has given enough time to adapt the packages. But today we’ll show you how to install it anyway using DNF.

So, let us start to install MongoDB on CentOS 8.

Install MongoDB on CentOS 8

The best way to install MongoDB is using its repositories, but the detail is that it seems that even many packages are not ready for CentOS 8. However, this method shown has proved reliable and effective.

First of all, open a terminal session and we have to configure the MongoDB repository. To do this, open a new file. You can use nano or Vi.

:~$ su
:~# nano /etc/yum.repos.d/mongodb-org-4.4.repo

And add the following:

[mongodb-org-4.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/development/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc

Save the changes and close the file.

Now, proceed to install MongoDB with the following command:

:~# dnf install mongodb-org

The next step is to start the MongoDB service using systemctl. So use the following command to do it:

:~# systemctl start mongod

To verify that everything is okay, it is a good idea to check the status of the service.

:~# systemctl status mongod

Finally, you can access to the MongoDB shell by using the following command:

:~# mongo

So, enjoy it.

Conclusion

MongoDB is one of the best NoSQL document-oriented database handlers. However, it seems to have problems adapting its packages to CentOS 8 and RHEL 8 and therefore, it can complicate the installation. But it hasn’t been difficult either and for now it has been stable.

Install Cezerin on Ubuntu 18.04

To install Cezerin it is necessary to have an Ubuntu 18.04 server that has the sudo command available.

On the other hand, since the application is built with NodeJS, it needs to be installed correctly. In addition, to manage the application data use the database manager NoSQL MongoDB. In other words, you have to install them both.

1) Install NodeJS on Ubuntu 18.04

The first step is to install NodeJS on Ubuntu 18.04. For that, we have a detailed tutorial that will make you achieve this goal.

Once you have finished, you will be able to continue with the guide.

2) Install MongoDB on Ubuntu 18.04

Now it is MongoDB’s turn. For this, we will use the version available in the official repository of the project. So add it and then install MongoDB.

First, open a terminal and run the following command to add the GPG key of the repository.

:~$ wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | sudo apt-key add -

It then adds the repository as such to the list of software origins.

:~$ echo "deb http://repo.mongodb.org/apt/debian stretch/mongodb-org/4.2 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list

After this, refresh the APT cache.

:~$ sudo apt update

Install MongoDB on Ubuntu with the following command:

:~$ sudo apt install mongodb-org mongodb-org-shell mongodb-org-server mongodb-org-mongos libcurl3

Check the installed version:

:~$ mongod -version
db version v4.2.0
git version: a4b751dcf51dd249c5865812b390cfd1c0129c30
OpenSSL version: OpenSSL 1.1.1  11 Sep 2018
allocator: tcmalloc
modules: none
build environment:
distmod: debian92
distarch: x86_64
target_arch: x86_64

3) Install Cezerin on Ubuntu 18.04

After installing the pre-requirements, we will be able to install Cezerin. To do this, navigate to your personal folder and download the source code using git.

:~$ cd ~
:~$ git clone https://github.com/cezerin/cezerin.git cezerin

Then, navigate into the folder and run:

:~$ cd cezerin
:~$ sudo npm install
:~$ sudo npm run build

Once the “compilation” has been completed, the application must be installed as such. To do this, simply use the following:

:~$ sudo npm run setup

Now you can start the program by using the following command:

:~$ sudo npm start

Now, open your web browser and go to http://Server-ip:3000. Remember to open the port on the firewall.

If you want to manage Cezerin as a systemd service, run the following commands:

:~$ sudo nano /etc/systemd/system/cezerin.service

And add the following:

[Unit]
Description=Cezerin

[Service]
ExecStart=/usr/bin/npm start
WorkingDirectory=/opt/cezerin
Restart=always
RestartSec=10
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=nodejs-example

[Install]
WantedBy=multi-user.target

To apply the changes, reload systemd.

:~$ sudo systemctl daemon-reload

Now, you can start it, enable it or stop it easily.

And that is it.

Conclusion

As you can see, it is quite simple to deploy an E-Commerce platform with Cezerin. Of course, the potential of the application makes the possibilities unimaginable.

MongoDB is one of the most popular NoSQL database managers in the world. Unlike managers like MySQL or PostgreSQL, it saves your records in documents so they are more understandable and operations faster to do. As I said, it is incredibly popular with developers.

So, let’s install MongoDB on OpenSUSE.

1. Upgrade the system

I always recommend everyone to update the system before starting any critical installation. Upgrading the system helps make it more stable and efficient.

:~$ sudo zyyper up

Now that the system is up to date, it is more stable and ready to start installing MongoDB.

2. Install MongoDB on OpenSUSE

MongoDB is not included in the official repositories of the distribution because it is a component that not everyone uses. Therefore, it is necessary to add the databases OpenSUSE repository to make the installation easy and above all secure.

So, run this command.

:~$ sudo zypper addrepo https://download.opensuse.org/repositories/server:database/openSUSE_Leap_15.0/server:database.repo

In this command, you are adding the external repository. Now you need to refresh the cache of the repositories.

:~$ sudo zypper refresh

Finally, install MongoDB.

:~$ sudo zypper in mongodb

And that it.

3. Use MongoDB to test the installation

The best way to verify that the installation has been successful is to use MongoDB. So, we will.

First, start the service.

:~$ sudo systemctl start mongodb

If you want MongoDB starts at the system boot:

:~$ sudo systemctl enable mongodb

Now, check the service status to see it is properly running.

:~$ sudo systemctl status mongodb

Access the MongoDB console and create an administrator user. Because by default, MongoDB does not create a user.

:~$ mongo

use admin 
  db.createUser({ 
  user: "root", 
  pwd: "your_password", 
  roles: [ "root" ] 
  }) 
  exit

Note: Replace your_password with your real password.

Next time, you can log in with admin user:

:~$ mongo --authenticationDatabase admin -u root -p

Note: When logging in you must specify the database to which the user has permission. In this case, root has permissions on the admin database. If you don’t specify it during logging you won’t be able to access it.

And that’s it. MongoDB is running correctly on your OpenSUSE 15.

Conclusion

As you can see the installation is really simple and only requires a few minutes of dedication. MongoDB is so powerful in its area that it makes it the most logical option within NoSQL databases.

Please share this post with your friends.
