Set the user and group for php-fpm-
-----------------------------------
sudo sed -i s'/user = apache/user = nginx/' /etc/php-fpm.d/www.conf && sudo sed -i s'/group = apache/group = nginx/' /etc/php-fpm.d/www.conf

Configure FPM-
--------------
sudo nano /etc/php/7.0/fpm/php.ini

##Check PHP Info-
--------------------------------
sudo nano /usr/share/nginx/html/info.php
<?php phpinfo(); ?>
--------------------------------


Configure FPM Process-
======================
sudo nano /etc/php-fpm.d/www.conf 
---------->>	Inside this file, find and uncomment the variable pm.status_path = /status	(9th page and stored screenshot)

Then, Check if anything broken in config file - sudo php-fpm -t

Then restart FPM-
	sudo systemctl restart php-fpm && sudo systemctl status php-fpm

--------------------------------------------------------------------------------
Now find and edit nginx default config-

realpath $(which nginx)

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

And then add this in location block-

location ~ ^/(status|ping)$ {
        allow 127.0.0.1;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_index index.php;
        include fastcgi_params;
        #fastcgi_pass 127.0.0.1:9000;
        fastcgi_pass   unix:/var/run/php-fpm.sock;
}
---------------------------------------------------------------------------------

sudo nano -w /etc/php.ini

And then find `cgi.fix_pathinfo`, uncomment and change it to - `cgi.fix_pathinfo=0`

	sudo systemctl restart nginx

Find listen = 127.0.0.1:9000 at /etc/php-fpm.d/www.conf and set it to:

	listen = /tmp/php-fpm.sock

Then find NginX config file location by - sudo nginx -t

Then, sudo nano /etc/nginx/nginx.conf

And add-

# php-fpm parsing php files
        location ~ .php$ {
            try_files $uri =404;
            fastcgi_pass   unix:/tmp/php-fpm.sock;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
            fastcgi_buffer_size 128k;
