Docker Container Connection Problem: After nginx and php-fpm –link, php programs cannot be parsed and solved normally.

  docker, question

1. This is how I built the container

Php-fpm container

docker run -itd --name php-fpm -v /Users/nibuw/Documents/devops/data/wwwlogs/php-fpm.log:/usr/local/php/var/log/php-fpm.log php:7.0.9

Operating status:

 root        19  0.0  0.1  47432  3392 ?  R+   10:49   0:00 ps uax

Nginx container

docker run -itd --name nginx_server -p 80:80 -p 443:443 --link php-fpm:php-fpm -v /Users/nibuw/Documents/devops/conf/nginx.conf:/usr/local/nginx/conf/  nginx.conf -v /Users/nibuw/Documents/devops/data/:/data nginx:1.11.3

Operating status:

[root@b23d2b95cf6e /]# ps aux

 root        20  0.0  0.1  47176  3324 ?  R+   10:48   0:00 ps aux

However:
Directly access the forwarded local IP

➜  ~ curl -I http://10.8.150.44

Access to PHP is a mistake

Dear gods, I have been torturing you for several days to find out what went wrong.

I also encountered this problem. Through the curl 9000 port, it was found that the access was not available, only to find that there was a problem with the listen configuration.

Modify the php/etc/php-fpm.d/www.conf file of the container where php-fpm is located:
; listen = 127.0.0.1:9000
listen = 0.0.0.0:9000
