PHP can not solve the problem listening port 9000/502 error solution

Background problem

Configuring nginx + php service, I found the site to open html, php file to open the display 502, generally this is a php did not start ah what the cause can not be resolved php file properly.

Cause Analysis

Because nginx php file is parsed to fastcgi_pass to deal with the default general fastcgi_pass There are two ways to parse php, one is the common tcp 9000 port is listening, here only resolve the tcp.

netstat -ntlp View 9000 port is not listening, do not listen on the default 9000port, and is listening/tmp/php-cgi-56.sock

[root@localhost pazzn]# netstat -ntlp   ###没有9000端口监听

solution

1. Find/php.conf

[root@localhost ~]# find / -name php-fpm.conf
/www/server/php/56/etc/php-fpm.conf
[root@localhost ~]#vi /www/server/php/56/etc/php-fpm.conf

2. ;Comment out the sock listening mode, increasing the listening port 9000

[global]
pid = /www/server/php/56/var/run/php-fpm.pid
error_log = /www/server/php/56/var/log/php-fpm.log
log_level = notice

[www]
#listen = /tmp/php-cgi-56.sock
listen = 9000
listen.backlog = -1
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.status_path = /phpfpm_56_status
pm.max_children = 80
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 20
request_terminate_timeout = 100
request_slowlog_timeout = 30
slowlog = var/log/slow.log

3. Restart php, php file parsing perfect open

[root@localhost ]# systemctl restart php-fpm-56.service

 

Note: nginx.conf must first ensure that the configuration file is correct, oh.
