How to Switch to TCP/IP from Unix Socket in Nginx

On my Prosper202 – Nginx tutorial, I use Unix Socket because it’s faster. But unix socket has some issues with high-loads. So if you’re experiencing 502 or 504 errors, switching to TCP/IP will solve it. So let’s do it.

Open PHP-FPM pool config file:

nano /etc/php5/fpm/pool.d/www.conf

Search for following line and uncomment it,

listen.backlog = 65536

Now search for following line,

listen = /var/run/php5-fpm.sock

And replace it with,

listen = 127.0.0.1:9000

Changes to php-fpm are now done. But there are some changes you should do to Nginx virtual host configurations. Open virtual host file for your domain with following command,

nano /etc/nginx/sites-available/example.com

Look for following line,

fastcgi_pass unix:/var/run/php5-fpm.sock;

And replace it with,

fastcgi_pass 127.0.0.1:9000;

Now restart php-fpm,

service php5-fpm restart

Then Nginx’

service nginx restart

And that’s it. You should edit all your virtual host files and make the above change.
