Fix : connect() to unix:/var/run/php5-fpm.sock failed

Here is an easy to understand & fix the error connect() to unix:/var/run/php5-fpm.sock failed. No Need to change to listen = 127.0.0.1:9000. Most websites unfortunately do not explain why the error connect() to unix:/var/run/php5-fpm.sock failed appears instead ask to open /etc/php5/fpm/pool.d/www.conf and change listen = /var/run/php5-fpm.sock to listen = 127.0.0.1:9000. Theoretically specking, this is a wrong way to fix as they are not dressing to solve the unix socket issue instead forcing to use TCP/IP. TCP/IP is slower.

It is unlikely to happen if you are reading our guide or script for any deb GNU/Linux. However, it might happen in case we miss few lines. PHP5 UNIX Socket was explained before in another guide. You might read that.

Google ranks which are popular websites, popular websites might not be technically correct. It is quite obvious, why Nginx and PHP5-FPM will throw an error which by default is activated? What exactly happens when we install Nginx and PHP5-FPM?

First, we almost never ask to change or check the Nginx user name in /etc/nginx/nginx.conf file assuming the server OS is Debian or Ubuntu. That socket thing which PHP5-FPM is reporting error, normally Nginx should create it properly and you’ll never get error.

Due to directory permission issues that automatic system fails. That is why we wrote that big guide – Ubuntu Nginx PHP5-FPM UNIX Socket Configuration. That should work in all cases, however we are making it more easy.

None tell that “look at Nginx config file for the user name”. For CentOS and other OS, user of Nginx is not www-data but nginx. If we run this command on SSH screen :

we will get the user name. For Debian and Ubuntu it is www-data. Whether you will change nginx (if your OS repo uses nginx instead of www-data), it depends on you. But, do not try all type of things together. First revert back to the condition you first noticed the error.

We have a file named php5-fpm.conf at /etc/nginx/conf.d location with this content :

Quite obviously, if Nginx user is nginx instead of www-data, then change the file ownership to www-data:nginx instead of root:www-data or www-data:www-data. There is no /var/run/php5-fpm.sock file in real.

If you fail to understand what we have written then go to stack overflow and ask the community to help you at the point you are failing pointing towards this guide. If this was not correct, you could not read this webpage!

We dislike changing the default name of this file – /etc/nginx/sites-available/default, in that file definitely you have kind of this line :

Instead of using php5-fpm.sock if you use php5-fpm.socket, again it will fail. Another file is at /etc/php5/fpm/pool.d/www.conf where listening is set to :

All we have set as php5-fpm.sock. If you hugely love the word php5-fpm.socket, then you have to change ALL the words from sock to socket. Many web hosts writes mixed words and peoples read and get errors, thats why we said. In the same file (/etc/php5/fpm/pool.d/www.conf) , you will find :

you can remove the comment and use this value :

Before restarting PHP5-FPM, do a config test :

then restart the services :

Do exactly what we wrote and tell us if ever fails!
