Step 4 – PHP-FPM Configuration

PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features.

sudo nano /etc/php/7.2/fpm/php.ini

un-comment cgi.fix_pathinfo=1 line and set value to 0.

cgi.fix_pathinfo=0

Now set the listen parameter in /etc/php/7.2/fpm/pool.d/www.conf configuration file. Here you can use php7.2-fpm socket to work or start php7.2-fpm service on specific port. We are going to use it as service .

sudo nano /etc/php/7.2/fpm/pool.d/www.conf

Now make changes in the configuration file as below. Commend listen to socket file and enable it as service

#listen = /run/php/php7.2-fpm.sock
listen = 127.0.0.1:9000

Step 5 – Nginx VirtualHost Configuration

Finally do the configuration of Nginx virtualhost. For this example we are editing default configuration file.

sudo nano /etc/nginx/conf.d/default.conf

and make changes as below.

server {
        listen   80;

        root /var/www;
        index index.php index.html index.htm;
        server_name  example.com www.example.com;

        location / {
                try_files $uri $uri/ /index.html;
        }

        error_page 404 /404.html;
        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
              root /usr/share/nginx/www;
        }

        location ~ .php$ {
                try_files $uri =404;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }
}

You have to do the same changes in all VirtualHosts configured.

Step 6 – Restart All Services

After installing and configuring all the services on your system, restart all required services to reload any changes made.

sudo service nginx restart
sudo service php7.2-fpm restart

Step 7 – Allow Firewall Access

If you are using iptables, Use following commands to open port 80 for public access of web server.

Iptables Users:

sudo iptables -A INPUT -m state --state NEW -p tcp --dport 80 -j ACCEPT

UFW Users:

$ sudo ufw allow 80/tcp

Step 8 – Test Setup

Finally, test the installation of PHP 7 with NGINX. Let’s create a file info.php on website document root using following content.

Now browse this file in web browser. It will so all the details about versions and installation.
