What is Laravel?

Laravel is one of the easiest open-source frameworks for PHP to assimilate. One of its advantages is that it has a much easier learning curve than other web and application development tools. It was created in 2011 and is heavily influenced by frameworks such as Ruby on Rails, Sinatra, and ASP.NET MVC.

With Laravel, we will have available other tools that together make up the power of Laravel.

• Blade: A powerful template manager where we can manage PHP variables directly in the view.
• Eloquent: Laravel’s database system, for writing and retrieving data. So we don’t have to work directly with SQL code.
• Routing: LAravel has its own routing system that helps us to set up the routing of our pages with GET or POST methods.

Besides this, Laravel is one of the best-documented frameworks that exist and with an active community willing to give support to the newbie.

So, let’s get started.

Install Laravel on Debian 11

Installing the Laravel requisites

First, you need to install PHP and some of its modules and the unzip package.

sudo apt install php php-bcmath php-json php-mbstring php-pdo php-tokenizer php-xml php-pear php-zip php-zip unzip

Install PHP Composer on Debian 11

The installation of laravel can be done without problems using PHP Composer. So we have to install it and keep it up to date.

For that, we invite you to read our post about it:

How to install PHP Composer on Debian 11?

Once it is installed and updated, we can follow the procedures.

Install Laravel on Debian 11

Now with the help of Composer, we have to install Laravel. To do this, run the following command

composer create-project --prefer-dist laravel/laravel [project_name]

Where the last value is where you have to specify the name of your project.

So, Composer will start with downloading and installing all Laravel dependencies. When finished, you will see an output screen like this

This will create a folder with the name of your project that we need to access.

cd example

And there will be all our Laravel working and ready for us to start creating code.

If you want to check how the project is running and also if you want to verify the installation, you can run

php artisan serve

Then open a web browser and go to http://localhost:8000 and you’ll see an image like this

In case Laravel has been installed on a server or another computer over the network, you can specify that it is accessible from another computer.

php artisan serve --host=0.0.0.0.0 --port=1234

This way you can access the computer and with the 1234 port you can change these values to your liking.

Conclusion

During this post, you have learned how to install laravel on Debian 11 so you can start developing cool applications that you can take to production. So, this is a powerful framework that you need to take full advantage of.

What is vnStat?

The best definition of Vnstat can be found on the project’s own website:

vnStat is a console-based network traffic monitor for Linux and BSD that keeps a log of network traffic for the selected interface(s). It uses the network interface statistics provided by the kernel as an information source. This means that vnStat won’t actually be sniffing any traffic and also ensures light use of system resources regardless of network traffic rate.

Therefore this tool is quite well known within the community and among sysadmins. It is quite simple to use and as you will see below it is easy to install.

Install vnStat on Debian 11 / 10

One of the fastest and most immediate ways to install vnStat on Debian 11 / 10 is to install it from the official repositories.

Although this is not the only way to get the program, it is the easiest method for newbies.

So, open a terminal or from an SSH session, install the security patches in the distribution:

sudo apt update
sudo apt upgrade

Next, you can install the vnStat package as follows:

sudo apt install vnstat

After it is installed, start the application service.

sudo systemctl start vnstat

This will complete the installation and you will be able to use it.

Install the latest version of vnStat on Debian 11 / 10

The previous method has a big problem and it is that the version that appears in the official repositories of Debian 11 / 10, is very outdated. So it is advisable to always install the latest version following these steps that I will describe.

First, install the packages needed to do the compilation, as well as some dependencies:

sudo apt install build-essential gcc make libsqlite3-dev

Then download the latest stable version, which at the time of writing this post, is 2.8.

wget https://humdi.net/vnstat/vnstat-2.8.tar.gz

Decompress the downloaded file

tar -xvzf vnstat-2.8.tar.gz

As a result of executing the above command, a folder called vnstat-2.8 will be generated which you will need to access and from there configure the package for compilation:

cd vnstat-2.8
./configure --prefix=/usr --sysconfdir=/etc

Now, compile the package and install it with this pair of commands:

sudo make
sudo make install

If everything went well, you will be able to run the vnstat command and display, for example, the installed version:

vnstat -v

Output:

vnStat 2.8 by Teemu Toivola <tst at iki dot fi>

Using the vnStat command

Before using the tool it is necessary to start the vnStat service. As we have installed it manually, there is no service installed so we have to create it.

Fortunately, to create it we will use the example file that comes with the code we have just compiled.

sudo cp -v examples/systemd/vnstat.service /etc/systemd/system/

Refresh the list of services

sudo systemctl daemon-reload

And now yes, enable it so it can start with the system and start the service

sudo systemctl enable vnstat
sudo systemctl start vnstat

And check the status of the service

sudo systemctl status vnstat
● vnstat.service - vnStat network traffic monitor
     Loaded: loaded (/etc/systemd/system/vnstat.service; enabled; vendor preset: enabled)
     Active: active (running) since Sat 2021-10-02 18:24:27 CEST; 11s ago

Oct 02 18:24:27 osradar vnstatd[5939]: Info: Monitoring (1): eth0 (1000 Mbit)

After waiting a few minutes, you can start using it.

vnstat

By default, it takes the active interface, but you can change it:

vnstat -i [interface]

When an interface is monitored, a new database with logs is created. You can delete it and reset the statistics.

sudo vnstat -i [interface] --remove --force

In this case, you have to specify the interface to monitor.

Enjoy it.

Conclusion

So now you know how to install and use vnStat on Debian 11 / 10 This command although simple allows you to find answers to the operation of a network interface and to know if the behavior is as expected…

Go is an open-source (BSD license) programming language that was born with the objective of allowing the creation of efficient and easily distributable applications. So, it has binaries for Windows, Mac OS and of course, for Linux.

So, in this post, I will install it and create a “Hello World” file for the test.

Download and install Go Language on Debian 11 /10

Go Language is cross-platform which makes it available for Linux. However, first you have to download the binaries from the project website. But we will use the terminal that is faster and more efficient.

First, make sure you have wget installed on your computer.

:~$ sudo apt install wget

Then proceed to download Go Language. At the time of writing this post, the latest stable version is 1.17

:~$ wget -c https://golang.org/dl/go1.17.linux-amd64.tar.gz -O go.tar.gz

Then, decompress it.

:~$ tar xvf go.tar.gz

Now you have to change the folder permissions. Besides moving it to another location like /usr/local/.

:~$ sudo chown -R root:root go
:~$ sudo mv go /usr/local

Then, it is necessary to make some modifications to the user’s bash profile in order to use Go. Open the configuration file and add the following:

:~$ sudo nano ~/.profile

export GOROOT=/usr/local/go    
export GOPATH=$HOME/work/
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

Save the changes (CTRL + O) and close the file (CTRL + X).

With this, Go is ready for work. You can check it by showing the version of the program.

:~$ go version

Now with a “hello world” we’ll see that everything works.

Testing the installation

As I said before, the best way to test the installation is to run a real code. For this, we will use the typical “Hello World”.

First, we’ll create the directory structure. In our Home, we will create a folder for the project called work. Inside a folder called src where the source code files will go. In it, a folder called hello and inside the file hello.go. Something like this is the directory structure. The folders work and hello can be called differently.

:~$ mkdir -p $HOME/work/src/hello

Now, create the Go file and add the following:

:~$ nano ~/work/src/hello/hello.go

package main 
 import "fmt"
 func main() {
 fmt.Printf("hello, world\n")
 }

Again, save the changes and close the file.

:~$ go build hello
:~$ go install hello
:~$ hello

So, enjoy it.

Conclusion

GO is a very popular language and every day it is more and more popular. It’s simple but very powerful, besides being open source. As you have seen, its installation is really simple.

So, Git?

If you are starting to develop applications you may not know that Git is a free, open-source version control system and that it is perhaps the best. Many developers rely on it to control the versions of their applications. By versions, we mean those in development.

Using Git you can control and separate development in each of those development branches. So the changes of one do not affect the others.

Read Introduction to the Git branches.

In this way, it is good practice to develop applications using a version control system as support.

Install Git on Debian 11 / 10

Debian 10 is one of the few distributions that have such complete package repositories. So, presumably, there is some Git in the official repositories.

However, it is also a good idea, to know how to install Git differently in case we need it. This way is compiling the source code of Git and get the latest stable version. In this tutorial, I will teach you how to do it both ways.

1) Using the official repository on Debian 11 / 10

Debian 11 / 10 include Git in the official repositories. Using this option, the installation is quite easy, and just open a terminal session and run the following command:

:~$ sudo apt install git

Or, if you do not have sudo, please read How to enable sudo on Debian 11/10?

Then, you can check the installed version.

:~$ git --version
git version 2.30.2

Now, you can use it.

2) Building the Git source code

Compiling the Git source code is the best way to get the latest version. All this in a safe way because it will not be compiled by third parties.

The process is simple but requires a few extra steps. So let us get started.

First, install the necessary programs to make the compilation:

:~$ sudo apt install build-essential make libssl-dev libghc-zlib-dev libcurl4-gnutls-dev libexpat1-dev gettext unzip

Now, we can download the source code.

:~$ cd /tmp/
:~$ wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.33.0.tar.gz

Next, decompress it and access to the folder.

:~$ tar xvfz git-2.33.0.tar.gz
:~$ cd git-2.33.0

Now, you can start the compilation by running the following commands:

:~$ sudo make prefix=/usr/local all
:~$ sudo make prefix=/usr/local install

Next, check the installed version.

:~$ git --version

And that is it. You can start to use Git.

Conclusion

Git is one of those applications that every developer must be able to manage to improve their workflow. Therefore, it is important to install it in Debian 10 and two ways have been shown to achieve this. One of them is using the package available in the official repositories and the other is compiling the source code.

Tele…what?

In the first place, What is Telegram? Well, Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time. In short, your messages sync seamlessly across any number of your phones, tablets or computers.

Some of the most powerful features that differentiate it from WhatsApp are the following:

• Telegram groups can have up to 100,000 members. It supports replies, mentions, and hashtags that help maintain order and keep communication in large communities efficient.
• If you want secrecy, try our device-specific Secret Chats with self-destructing messages, photos, and videos.
• Telegram has bots. Bots are like small programs that run right inside Telegram. They are very useful to extends Telegram functionality.
• The Telegram API is accessible. This allows anyone to develop an unofficial client. Don’t worry, security is something Telegram takes seriously.

There are many characteristics that make Telegram a perfect application. In my case, in particular, I have noticed that it is much faster and safer than WhatsApp.

Let’s install Telegram

If you want to install Telegram in any Linux distribution, I must tell you that it is something very simple. Telegram does take into account Linux users, creating an official client on a par with Windows and Mac OS. Already that speaks very well of it.

In the first place, you need to go to the official Telegram website.

Then, download the client for Linux.

When the download is complete, decompress the file. Next, open your file browser and you will see two files.

Then, assign execution permissions to the Telegram file. Right-click on it and go to Properties.

Now, you can open it. Double-click on it.

Click on Start Messaging button to add your phone number.

Then, Telegram will send you a code via SMS. When you type it, the application will start and you will use it without any problem.

And that’s it.

Conclusion

Telegram is much better than WhatsApp not only because of its features but also because its desktop customers are very good. Installing these desktop clients is simple and very useful.

Recently we talked about Franz an application to have several messaging accounts on the desktop. You might be interested so here’s the link.

So, LibreOffice is one of the jewels of open source. We are talking about a complete office suite capable of resulting in a free, cross-platform solution available to everyone. Therefore, it already comes installed in many Linux distributions but these do not include an updated version.

Install LibreOffice 7.1 on Ubuntu 20.04 / Linux Mint 20

There are several methods to install LibreOffice 7.1 on Ubuntu 20.04 or Linux Mint 20. However, I will show you the two easiest to do, and that allows you to easily keep it updated.

Installing LibreOffice 7.1 using PPA

The LibreOffice development team provides us with a dedicated PPA for LibreOffice 7.1. This repository is compatible with Ubuntu 20.04 as it could not be otherwise. So let’s use it.

So, open a terminal and run the following command:

:~$ sudo add-apt-repository ppa:libreoffice/ppa
In general, users are advised to take a look at the changelog for the details about a package. If there is a specific bug that is intended to be addressed by an update released into the PPA, you are encouraged to test, if the update solves that problem. Packages published after the distro release are mostly such specific fixes. Critical fixes will be SRUed into the main repositories after testing anyway (later, with more testing).

To return to the LibreOffice version from the main archive, use ppa-purge. see: http://www.webupd8.org/2009/12/remove-ppa-repositories-via-command.html for details
 More info: https://launchpad.net/~libreoffice/+archive/ubuntu/ppa
Press Enter to continue or Ctrl+C to cancel

Executing: /tmp/apt-key-gpghome.VVwU2zyIO1/gpg.1.sh --keyserver hkps://keyserver.ubuntu.com:443 --recv-keys 36E81C9267FD1383FCC4490983FBA1751378B444
gpg: key 83FBA1751378B444: public key "Launchpad PPA for LibreOffice Packaging" imported
gpg: Total number processed: 1

:~$ sudo apt-get update

And then, if you already have LibreOffice installed, upgrade your system:

:~$ sudo apt upgrade

Or:

:~$ sudo apt full-upgrade

It’s that simple. Next, launch it from the main menu.

Installing LibreOffice 7.1 with Flatpak

If we read the description of the previous repository we will notice that it will only provide updates to the 7.1 branch

To avoid this, it is possible to use Flatpak. As we know, Flatpak is a technology that allows us to create self-contained and secure packages for any Linux distribution.

The Flatpak package of LibreOffice is hosted in Flathub and they give us the instructions to install it.

So, install Flatpak in case you don’t have it installed:

:~$ sudo apt install flatpak

Then, install LibreOffice 7.1 with the following command:

:~$ flatpak install flathub org.libreoffice.LibreOffice

When the download is finished you can run it from the main menu. Or by executing the following command:

:~$ flatpak run org.libreoffice.LibreOffice

So, enjoy it.

Conclusion

LibreOffice 7.1 is available for download. In this post, you’ve learned what to do to get it right now on your Ubuntu 20.04. But this tutorial works for Linux Mint 20 and all distributions that are based on Ubuntu 20.04.

Meeting Wing

Wing is an IDE for Python that is presented to us as one quite fast and with the slogan of being as productive as possible. With 3 versions, the first is Wing Pro which is a paid version with all the features that the project offers. The second is Wing Personal oriented to students and middle-level programmers who will have an IDE without so many features but functional and agile to get the job done. The last one is Wing 101 which is a basic version of the application. It is used by teachers to teach about Python.

Of course, the main features of Wing are present in all versions. However, it is fair to say that Wing Pro is the most complete version and is at the same level as other solutions such as PyCharm.

Some of the features found in all versions of Wing are:

• It has improved the support of multiple selections.
• Raspberry Pi support has been improved.
• Support for Python 3.8 / 3.7 and Stackless 3.4.
• Autocompletion in strings and comments.
• Syntax indicator and error indicators. Syntax highlighting for Markdown files.
• Optimized debugger.
• Support for Django

Although the license of Wing Pro is not high, they have a program where they give licenses to developers who collaborate in open source projects. It’s a great way to collaborate with the open source community and with these projects.

In addition, as expected Wing is available for Windows, Linux and MacOS. However, where it is best programmed is in our Linux system. So there I will teach you how to install it.

Install Wing Python IDE on Ubuntu 20.04 / 18.04

At the time of writing this post, the version of Wing is the 7.0.3 that was recently released. It has many code improvements and bug fixes.

In the download section of the Wing website, we will have different options, in this case, install Wing Personal because I think it is enough for most. Then, download the DEB file.

However, you can do it from the terminal. To do this, open it and run this command.

:~$ wget -c https://wingware.com/pub/wing-personal/7.2.9.0/wing-personal7_7.2.9-0_amd64.deb

After that, install it.

:~$ sudo apt install ./[file_path]

Then, launch it from the main menu.

Now, enjoy it.

Conclusion

Programming is not a simple matter; on the contrary, it entails great difficulties. Having tools to facilitate the process is the essence of IDE. In this context, Wing is a quite competent IDE for python and is presented as a serious alternative in the market.

Please, share this post.

Rust is an open source, multipurpose and new programming language that aims to retire to the C language. Although it is sponsored by Mozilla and Samsung, it is a community project. Its focus is primarily on large programs that run on the client and server side.

The main characteristics of Rust are performance, reliability, and productivity. Rust can compile and create applications very quickly; it is conducive to very few failures and its large documentation makes it possible to learn quickly.

Install Rust Programming Language on Fedora 34

The installation is quite simple to perform through the terminal. To do this, first, make sure that the distribution is up to date.

So, open a terminal and run

sudo dnf update

After that you should install the development and build tools for this our post will help you.

After that, you can install the curl and nano packages with which we can complete the post.

sudo dnf install nano curl

Now proceed to download and run the installation script provided by the Rust developers.

curl https://sh.rustup.rs -sSf | sh

During the execution of the script, we will be asked about the type of installation. In this case, choose option 1.

Then the whole installation process will continue and at the end, you will see the following screen:

This way the installation has been completed successfully. To make Rust available from the terminal without any problems run

source $HOME/.cargo/env

Now we are ready to try Rust. We are ready to test Rust, for example, show the installed version.

rustc --version
rustc 1.53.0 (53cb7b09b 2021-06-17)

Your first program with Rustc

Now to check that everything is OK we need to create a program. We will do the classic “Hello World”.

First, create the necessary directory structure and access it.

mkdir ~/projects
cd projects
mkdir example
cd example

Obviously, you can change the names and adjust them to your preferences.

Now create the code file

nano helloworld.rs

And add the following code:

fn main() {
println!("Hello, thanks for visiting Osradar blog.");
}

Save the changes and close the editor.

Now compile the program

rustc helloworld.rs

And run it

./helloworld
Hello, thanks for visiting Osradar blog.

So, Rust is installed.

Conclusion

Installing the Rust language in Linux is a fairly simple process. The possibilities offered by this language are many. It is also a great alternative to traditional programming languages.

Install PostgreSQL 13 on CentOS 8 / RHEL 8 / Oracle Linux 8

Both RHEL 8 and its derivatives include PostgreSQL 10 in their repositories. However, we already have available version 13. And it is recommended to install it because thanks to it, we can enjoy interesting news and improvements in the performance of the application. Important, if we are going to store large quantities of records.

So first, open a terminal session. Or if you are using a server connect to it using ssh.

:~$ ssh [your-user]@[your-host]

Then log in as the root user.

:~$ su
:~#

The best way to install PostgreSQL 13 on CentOS 8, RHEL 8 and Oracle Linux 8 is to add the official PostgreSQL refill. Not only is it easy, but also safe and the possibility to be always up to date.

To do this, run the following command:

:~# dnf install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm

Then, disable the PostgreSQL module on CentOS 8.

:~# dnf module disable postgresql

Now, install PostgreSQL 13 on CentOS 8.

:~# dnf install postgresql13-server postgresql13

After that, let us configure it.

Configure PostgreSQL on CentOS / RHEL 8 / Oracle Linux 8

Initialize PostgreSQL database and start the service

After installing it, the first thing to do is to initialize the database. To achieve this, it is necessary to execute the following command:

:~# /usr/pgsql-13/bin/postgresql-13-setup initdb
Initializing database ... OK

With this, we will have already started the initial database. At this point, the PostgreSQL service is not enable, so you can’t use it yet. Then you have to do it.

:~# systemctl enable postgresql-13

Then, if you want PostgreSQL to start along with the system run this command:

:~# systemctl start postgresql-13

To check that everything is going well, check the status of the service:

:~# systemctl status postgresql-13

As you can see, everything’s fine.

Change the password to the “postgres” user and allow the remote connections

During the installation of PostgreSQL, a new user called postgres is created. The problem is that you do not define a password, so it makes you vulnerable. To avoid problems, it is convenient to create a password.

To do this, just use the Unix passwd command.

:~# passwd postgres

There you will have to enter the password twice. If both are effective, the final change will be made.

Now, we have to allow access to remote connections. The client must be installed on each of the systems that will access PostgreSQL. It will depend on each operating system.

Then, a good security measure is to specify the hosts that can access it. Of course, if the data will be served on the Internet, then it is necessary to allow all the accesses.

:~# nano /var/lib/pgsql/13/data/postgresql.conf

then searches for the listen_addresses line and places the hosts that can access it. If you allow any access, type ‘*’.

listen_addresses = '[host/IP_adress]'
or
listen_addresses = '*'

Then, restart PostgreSQL.

:~# systemctl restart postgresql-13

Finally, you have to open the port 5432 on the firewall to allow the connections.

:~# firewall-cmd --add-port=5432/tcp --permanent
success
:~# firewall-cmd --reload
success

Now, you can access to the PostgreSQL shell.

:~# su - postgres
:~# psql

Now, you can start to work.

Conclusion

PostgreSQL is one of the best there is for databases. Thanks to its community spirit, it is possible to find a lot of documentation about it. On the other hand, installing version 13 on CentOS 8, RHEL 8 and Oracle Linux 8 is quite simple as you have seen in this post.

Also, you can read how to install Postgresql on Ubuntu 18.04?

Please share this post with your friends and join our Telegram channel.

The post How to install PostgreSQL 13 on CentOS 8 / RHEL 8 / Oracle Linux 8? appeared first on Linux Windows and android Tutorials.

PostgreSQL 13 is the latest stable version of what is perhaps the most advanced open-source relational database manager. So many sysadmin need to have it on the different servers.

If you want to know all the news or at least the most important ones, you can read this post

PostgreSQL 13 is available

Well, PostgreSQL 13 comes with many important improvements and it’s a good time to install it. That’s what this post is about.

So let’s go for it.

Install PostgreSQL 13 on Debian

PostgreSQL is included in the official Debian repositories, but not in version 13 but in version 11.

The installation of PostgreSQL 13 is possible thanks to the repository it has for APT package managers that is used by Debian, Ubuntu, Linux Mint and derivatives.

So let’s start.

First, open a terminal session or connect to your server using SSH. Then, install some necessary packages:

:~$ sudo apt install gnupg gnupg2

At the end, the PostgreSQL 13 repository should be added to the list of Debian software sources. To do this, create the following file:

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

And in it he adds the following:

deb http://apt.postgresql.org/pub/repos/apt/ buster-pgdg main

Then save the changes by pressing CTRL + O and close the file by pressing CTRL + X.

For the repository to be accepted by the system, you need to add the gpg key to it. To do this, use the following command:

:~$ wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
OK

Once the process has been completed, simply update the APT cache.

:~$ sudo apt update

You can now view all the packages related to PostgreSQL 13 by typing

:~$ sudo apt install postgresql-13

But don’t press enter, just press the TAB key and you’ll see the following:

As you can see in the image, we have PostgreSQL 13 available. So to install it run the following command:

:~$ sudo apt install postgresql-13
Reading package lists... Done
Building dependency tree 
Reading state information... Done
The following additional packages will be installed:
libgdbm-compat4 libjson-perl libllvm7 libperl5.28 libpq5 libxslt1.1 perl pgdg-keyring postgresql-client-13 postgresql-client-common postgresql-common ssl-cert
Suggested packages:
perl-doc libterm-readline-gnu-perl | libterm-readline-perl-perl make libb-debug-perl liblocale-codes-perl postgresql-doc-13 openssl-blacklist
Recommended packages:
libjson-xs-perl sysstat
The following NEW packages will be installed:
libgdbm-compat4 libjson-perl libllvm7 libperl5.28 libpq5 libxslt1.1 perl pgdg-keyring postgresql-13 postgresql-client-13 postgresql-client-common postgresql-common
ssl-cert
0 upgraded, 13 newly installed, 0 to remove and 10 not upgraded.
Need to get 34.5 MB of archives.
After this operation, 145 MB of additional disk space will be used.
Do you want to continue? [Y/n]

Now we’ll see if everything went well.

Testing the installation

By default, Debian when installing PostgreSQL starts and enables the service. Therefore, it is ready to be tested. However, if you want to stop the service, you can use this command:

:~$ sudo systemctl stop postgresql

On the other hand, the best way to know if PostgreSQL is ready for work is to execute some command from the console. So we’ll access it first:

:~$ sudo -i -u postgres

Remember that the PostgreSQL console is accessed through the postgres user.

And finally, we access with this command:

:~# psql

Once inside, we can, for example, display all the databases in the system:

:~# \l

And so we can work without problems with PostgreSQL.

Conclusion
