Installing Symfony on CentOS 7

Symfony is a powerful PHP framework designed for building web applications. It follows the Model-View-Controller (MVC) architectural pattern, making it easy to develop and maintain complex web projects.

Step 1: Update the System

First, update your CentOS 7 server to ensure you have the latest software packages:

# sudo yum update

Step 2: Install PHP

Symfony requires PHP to run. Install PHP and its dependencies using the following command:

# sudo yum install php php-cli php-mbstring php-xml

Step 3: Install Composer

Composer is a dependency manager for PHP that Symfony utilizes. Install Composer by downloading the Composer installation script:

# sudo curl -sS https://getcomposer.org/installer | php

Then, move the Composer binary to the /usr/local/bin directory:

# sudo mv composer.phar /usr/local/bin/composer

Step 4: Install Symfony

Now, you are ready to install Symfony. Run the following command to install Symfony using Composer:

# sudo composer create-project symfony/website-skeleton myproject

This command will create a new Symfony project named "myproject" in the current directory.

Step 5: Start the Symfony Development Server

To test the installation, navigate to the project directory and start the Symfony development server:

# cd myproject # php bin/console server:run

You should see a message indicating that the server is now listening on http://127.0.0.1:8000. Open a web browser and visit this URL to see the default Symfony welcome page.

Step 6: Working with Symfony

From here, you can start building your Symfony application. Symfony provides a flexible modular framework with countless features for developing web applications. You can define your routes, controllers, and views to create powerful and dynamic web pages.
