Set up Symfony

Using mod_proxy_fcgi with Apache 2.4

If you are running Apache 2.4, you can easily use mod_proxy_fcgi to pass incoming requests to PHP-FPM. Configure PHP-FPM to listen on a TCP socket, enable mod_proxy and mod_proxy_fcgi in your Apache configuration and use the SetHandler directive to pass requests for PHP files to PHP FPM:

Note: mod_proxy_fcgi now supports network sockets since 2.4.9 ( Unix socket support for mod_proxy_fcgi ). https://wiki.apache.org/httpd/PHP-FPM

# vim /etc/httpd/conf.d/httpd-vhosts.conf

<VirtualHost *:80>
    ServerName domain.tld
    ServerAlias www.domain.tld

    # Uncomment the following line to force Apache to pass the Authorization
    # header to PHP: required for "basic_auth" under PHP-FPM and FastCGI
    #
    # SetEnvIfNoCase ^Authorization$ "(.+)" HTTP_AUTHORIZATION=$1

    # For Apache 2.4.9 or higher
    # Using SetHandler avoids issues with using ProxyPassMatch in combination
    # with mod_rewrite or mod_autoindex
    <FilesMatch \.php$>
        SetHandler proxy:fcgi://127.0.0.1:9000
    </FilesMatch>

    # If you use Apache version below 2.4.9 you must consider update or use this instead
    # ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/var/www/project/web/$1

    # If you run your Symfony application on a subpath of your document root, the
    # regular expression must be changed accordingly:
    # ProxyPassMatch ^/path-to-app/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/var/www/project/web/$1

    DocumentRoot /var/www/project/web
    <Directory /var/www/project/web>
        # enable the .htaccess rewrites
        AllowOverride All
        Require all granted
    </Directory>

    # uncomment the following lines if you install assets as symlinks
    # or run into problems when compiling LESS/Sass/CoffeScript assets
    # <Directory /var/www/project>
    #     Options FollowSymlinks
    # </Directory>

    ErrorLog /var/log/apache2/project_error.log
    CustomLog /var/log/apache2/project_access.log combined
