In this short tutorial, we will install Symfony and its basic requirements on our Fedora System. So open your terminal and let's begin.

NOTE: Make sure your user has superuser access.

1 - Install PHP

First, we need to have PHP installed in our system. In your terminal, paste the following command to install php-cli:

sudo dnf install -y php-cli

Let's verify that PHP is installed in our system:

php --version

The output should be similar to the following screenshot:

In this case, we have PHP version 8.1 with Parch 18 installed. Now that we have PHP installed, let's install Composer.

2 - Install Composer

What is PHP Composer`?: Composer is the package manager of PHP. It manages all the dependencies of a project for us so that we can focus on our project without worrying.

To install Composer, copy and paste the following command in your terminal.

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

php -r "if (hash_file('sha384', 'composer-setup.php') === '55ce33d7678c5a611085589f1f3ddf8b3c52d662cd01d4ba75c0ee0459970c2200a51f492d557530c71c15d8dba01eae') { 
echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

php composer-setup.php

php -r "unlink('composer-setup.php');"

This shell script below does 4 things:

• Download the composer-setup.php script.

• Verify the hash script of the script.

• Run the composer-setup.php script.

• Delete the composer-setup.php script from the current directory.

Running the command ls -la, you can observe that the current directory has only 1 file left called composer.phar.

composer.phar is the executable of the php package manager called composer.

Now let's move the composer executable to our /usr/local to access it globally, and let add /usr/local folder in our $PATH environment variable:

sudo mv composer.phar /usr/local/composer
echo "PATH=$PATH:/usr/local/" >> ~/.bashrc

Now that's done, let's execute our .bashrc file to make the changes immediately available:

source ~/.bashrc

Check if Composer is installed in your system with the following command:

composer --version

The result should be similar to the following screenshot the following:

3 - Install Symfony Framework

When you have installed in your Fedora system PHP and Composer, you can now install Symfony Framework.

From Oficial Symfony Website: In your terminal, copy and paste the following command (either use wget or curl):

• Install Symfony with wget:

wget https://get.symfony.com/cli/installer -O - | bash

• Install Symfony with curl:

curl -sS https://get.symfony.com/cli/installer | bash

Either way should show us the following result:

Now lets add symfony to our $PATH environment variable:

echo 'PATH="$HOME/.symfony5/bin:$PATH"' >> ~/.bashrc

And execute the ~/.bashrc file to make the changes immediately available:

source ~/.bashrc

Lastly, lets check if Symfony is installed in our system:

symfony check:requirements

Conclusion

In this short tutorial, we have installed PHP, Composer and Symfony. In the next tutorials of this series, we will go deeper into how to use Symfony for web projects.
