Editor to share with you the cgi process in php does not have a solution, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

There are no solutions for the php cgi process: 1, open the corresponding configuration file; 2, keep the listen in php-fpm.conf consistent with the conf listen in nginx.conf or vhost.

This article operating environment: linux5.9.8 system, PHP5.6,Dell G3 computer.

Is there a php cgi process? PHP successfully started php-fpm, but the php-cgi process could not find 502 getaway?

Generally speaking, after we have just installed the lnmp environment and changed the fastcgi_pass unix:/tmp/php-cgi.sock entry in nginx to fastcgi_pass 127.0.0.1 fastcgi_pass 9000, the web access prompts 502 error pages. You can't find the php-cgi process using netstat-tlunp.

Solution:

1. LNMP uses unix sockets by default, and the parameter fastcgi_pass in the virtual host configuration file is unix:/tmp/php-cgi.sock.

Need to make sure the settings in / usr/local/php/etc/php-fpm.conf

Php version 5.3 and above is listen = / tmp/php-cgi.sock

At the same time, the fastcgi_pass unix:/tmp/php-cgi.sock; inconsistency in the virtual host configuration under / usr/local/nginx/conf/nginx.conf and / usr/local/nginx/conf/vhost/ is bound to be 502.

two。 Sometimes it may be 502in unix socket mode.

You can try to change it to tcp/ip.

Replace php version 5.3 and above listen = / tmp/php-cgi.sock with listen = 127.0.0.1 tmp/php-cgi.sock. Replace fastcgi_pass unix:/tmp/php-cgi.sock; with fastcgi_pass 127.0.0.1 tmp/php-cgi.sock in the configuration file and virtual host configuration file. Try rebooting later.

Summary:

/ usr/local/php/etc/php-fpm.conf listen should be consistent with conf listen in nginx.conf or vhost

To be consistent with nginx configuration
