    Symfony is a web application framework written in PHP. Its provides a set of reusable PHP components. Symfony 3 is the latest version available of this releases. Currently it is providing 30 stand-alone components for your applications.

    This tutorial will help you to install Symfony 3 php framework on CentOS, Red Hat and Fedora operating systems

    Step 1 – Setup Yum Repositories

    First you need to add REMI and EPEL rpm repositories in your system. these repositories have updated packages. Use one of the below command as per your OS version and system architecture.

    CentOS/RHEL 7, 64 Bit System: 
    # rpm -Uvh http://free.nchc.org.tw/fedora-epel/7/x86_64/e/epel-release-7-5.noarch.rpm
    # rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
    
    CentOS/RHEL 6, 64/32 Bit System: 
    # rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
    # rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
    
    CentOS/RHEL 5, 64/32 Bit System: 
    # rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-releas5-4.noarch.rpm
    # rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
    

    Step 2 – Install Apache, MySQL and PHP

    To start with Symfony 3 installation, we first need to setup a running LAMP server. If you have already running LAMP stack skip this step else use followings commands to setup lamp stack.

    Install Apache

    # yum --enablerepo=remi,epel install httpd
    

    Install MySQL

    # yum --enablerepo=remi,epel install mysql-server
    # service mysqld start
    # /usr/bin/mysql_secure_installation
    

    Install PHP

    # yum --enablerepo=remi,epel install php php-mysql php-intl
    # service httpd restart
    

    Step 3 – Setup Symfony Installer

    Symfony provides its own installer for creating new projects. Below commands will help you to setup Symfony installer on your system.

    # curl -LsS https://symfony.com/installer -o /usr/local/bin/symfony
    # chmod a+x /usr/local/bin/symfony
    

    Step 4 – Create New Symfony 3 Application

    After successful setup of Symfony installer on your system. Let’s start with your new Symfony application. Navigate to your web document root and create a new Symfony application.

    # cd /var/www/html
    # symfony new myproj
    

    Now change to newly created directory and check if all requirements are properly installed on your system. If everything is fine you will get following results.

    # php myproj/bin/symfony_requirements
    
     [OK]
     Your system is ready to run Symfony3 projects
    

    Step 5 – Start Application in Development Mode

    Now start development with Symfony 3 php framework and built great application’s. To view changes in browser you can start Symfony development web server using following command. By default web server will start on port 8000.

    # php bin/console server:run
    
     [OK] Server running on http://127.0.0.1:8000
     // Quit the server with CONTROL-C.
    

    Now access new Symfony 3 application in your browser by accessing http://127.0.0.1:8000 or http://localhost:8000 .

    install symfony 3 framework

    Step 6 – Create Apache VirtualHost

    Now If you need to configure Symfony 3 with sub domain. Create a new Apache configuration file under directory /etc/httpd/cond.d/ and add Virtual Host for your Symfony 3 application.

    # vim /etc/http/conf.d/symfony3.example.com.conf
    

    directory and add below content.

    <VirtualHost *:80>
        ServerName symfony3.example.com
        DocumentRoot /var/www/html/myproj/web
    
        <Directory /var/www/html/myproj/web>
            AllowOverride All
            Order Allow,Deny
            Allow from All
            <IfModule mod_rewrite.c>
                Options -MultiViews
                RewriteEngine On
                RewriteCond %{REQUEST_FILENAME} !-f
                RewriteRule ^(.*)$ app.php [QSA,L]
            </IfModule>
        </Directory>
    
        ErrorLog /var/log/httpd/myproj_error.log
        CustomLog /var/log/httpd/myproj_access.log combined
    </VirtualHost>
    
    

    After making all changes, now restart Apache server to changes take effect.

    # service httpd restart
    

    Now make a host file entry to access new Symfony 3 application in your browser with your domain name like http://symfony3.example.com. Change symfony2.example.com and 127.0.0.1 as per your setup.

    # echo "127.0.0.1  symfony3.example.com" >> /etc/hosts
