Nginx unix:/tmp/php-cgi.sock error solution

First create the/tmp/php-cgi.sock file and change it to www-data:

# For nginx users, it seems that they must belong to the nginx user group before they can be properly used and not verified
Sudo chown www-data/tmp/php-cgi.sock

To nginx. conf, if you are using a virtual machine, change the file to/etc/nginx/site-available:

Modify:
# Fastcgi_pass 127.0.0.1: 9000;
Fastcgi_pass unix:/tmp/php-cgi.sock;

Find init. d/php-cgi (refer to the article about switch ):

Modify:
# DAEMON_OPTS = "-a 127.0.0.1-p 9000-C 1-u www-data-f/usr/bin/php-cgi"

DAEMON_OPTS = "-a 127.0.0.1-s/tmp/php-cgi.sock-C 1-u www-data-f/usr/bin/php-cgi"

Restart nginx and spawn-fcgi respectively, and your nginx efficiency will be higher! :-)
