How to install symfony on Centos 9 Stream

Symfony is a powerful PHP framework for building high-performance and enterprise-grade web applications. It’s known for its stability, modular structure, and scalability. Installing Symfony on CentOS Stream 9 gives developers a reliable and secure environment for modern PHP development.

Update the System

Before installing anything, update your CentOS Stream 9 system to ensure you have the latest security patches and package updates:

sudo dnf update -y

Install PHP and Required Extensions

Symfony requires PHP 8.2 or higher. You can install it using the AppStream or Remi repository.

First, enable the Remi repository for newer PHP versions:

sudo dnf install -y dnf-utils
sudo dnf install -y https://rpms.remirepo.net/enterprise/remi-release-9.rpm
sudo dnf module reset php -y
sudo dnf module enable php:remi-8.2 -y

Then install PHP with all required extensions:

sudo dnf install -y php php-cli php-common php-mbstring php-xml php-zip php-curl php-intl php-sqlite3 unzip git

Verify PHP installation:

php -v

You should see output like:
PHP 8.2.x (cli) (built: ...)

Install Composer

Symfony uses Composer, the PHP dependency manager, to handle packages and libraries.

Run these commands to install it globally:

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php composer-setup.php
sudo mv composer.phar /usr/local/bin/composer
php -r "unlink('composer-setup.php');"

Check Composer’s version:

composer --version

Install Symfony CLI

Symfony offers a CLI tool that simplifies project creation and management.

Download and install it:

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

Move it to a global location so you can run it from anywhere:

sudo mv ~/.symfony*/bin/symfony /usr/local/bin/symfony

Check if the Symfony CLI is working:

symfony -v

Create a New Symfony Project

Now that all dependencies are ready, create a new Symfony project:

symfony new my_project --webapp

This command installs Symfony with all standard components (Twig, Doctrine, etc.) and sets up the directory structure automatically.

Move into the project directory:

cd my_project

Run Symfony’s Local Web Server

symfony serve

[OK] Web server listening on https://127.0.0.1:8000

sudo chown -R $USER:$USER ~/my_project

sudo dnf install -y httpd php php-cli php-mbstring php-xml php-json
sudo systemctl enable httpd
sudo systemctl start httpd
