Using /var/run/php5-fpm.sock isn’t required and you can swap back over to TCP quickly and easily.

First thing we need to do is login to SSH as root or your sudo user and then navigate to:

cd /etc/php/5.6/fpm/pool.d

You’ll see a file named www.conf`. That’s the file we need to modify, so go ahead and open it:

nano www.conf

Now we need to find the line that looks like this:

listen = /run/php/php5.6-fpm.sock

Change that line to read:

listen = 127.0.0.1:9000

Then restart php-fpm using:

service php5.6-fpm restart

The only time this won’t work is if NGINX is configured to route PHP requests to another port, such as 9001, 9002, etc. This is possible, so if the above doesn’t work, don’t worry, we just need to do a little more investigating.

You’d want to browse over to /etc/nginx and look in sites-available for your NGINX server block configuration file, open it and find the location block that handles your PHP requests and see what the port is there.

cd /etc/nginx/sites-available

Once you have the port that is set in one of the configuration files for your site, simply copy that port to the above PHP-FPM configuration. In most cases, 9000 is the default, but in rare cases, some pre-configurations use another.
