yum --enablerepo=remi,epel install php php-mysql php-intlservice httpd restartStep 3:
Since Symfony provides its own installer for creating new projects, you need to setup a Symfony installer on your system. So, run:
curl -LsS https://symfony.com/installer -o /usr/local/bin/symfonychmod a+x /usr/local/bin/symfonyStep 4:
Once the Symfony installer is setup on your system, create a New Symfony Application. To start with your new Symfony application, navigate to your web document root:
cd /var/www/htmlsymfony new myprojThen, run the below command to change to the newly created directory and check if all requirements are properly installed on your system:
php myproj/bin/symfony_requirementsNote: If everything is fine you will get the ” Your system is ready to run Symfony projects” message.

To configure Symfony with a subdomain, you need to create a new Apache configuration file under directory /etc/httpd/cond.d/ and add Virtual Host for your Symfony application:
vim /etc/http/conf.d/symfony5.example.com.confThen, add the below content to the directory:
<VirtualHost *:80> ServerName symfony5.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>When the changes are finished, restart the apache server to changes take effect:
service httpd restartTo access the new Symfony 5 application, you can make a host file entry in your browser with your domain name like http://symfony5.example.com. Just change symfony5.example.com and 127.0.0.1 as per your setup:
echo "127.0.0.1 symfony5.example.com" >> /etc/hostsNow, you should be redirected to the Symfony default dashboard.
