Nginx configuration for symfony

Create a config file “sub.example.com” in etc/nginx/site-availabe and ensure the php version

For symfony 4.x

server {
    server_name domain.tld www.domain.tld;
    root /var/www/project/public;

    location / {
        # try to serve file directly, fallback to app.php
        try_files $uri /index.php$is_args$args;
    }
    # DEV
    # This rule should only be placed on your development environment
    # In production, don't include this and don't deploy index_dev.php or config.php
    location ~ ^/(index_dev|config)\.php(/|$) {
        fastcgi_pass unix:/var/run/php7.2-fpm.sock;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        # When you are using symlinks to link the document root to the
        # current version of your application, you should pass the real
        # application path instead of the path to the symlink to PHP
        # FPM.
        # Otherwise, PHP's OPcache may not properly detect changes to
        # your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
        # for more information).
        # Caveat: When PHP-FPM is hosted on a different machine from nginx
        #         $realpath_root may not resolve as you expect! In this case try using
        #         $document_root instead.
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $realpath_root;
    }
    # PROD
    location ~ ^/index\.php(/|$) {
        fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
       # When you are using symlinks to link the document root to the

       fastcgi_param DOCUMENT_ROOT $realpath_root;
       # Prevents URIs that include the front controller. This will 404:
       # http://domain.tld/app.php/some-path
       # Remove the internal directive to allow URIs like this
       internal;
   }

   # return 404 for all other php files not matching the front controller
   # this prevents access to other php files you don't want to be accessible.
   location ~ \.php$ {
     return 404;
   }

   error_log /var/log/nginx/project_error.log;
   access_log /var/log/nginx/project_access.log;
}
