docker部署nginx+php-fpm环境访问动态文件404报错

中午用docker不熟nginx php-fpm 环境时，访问php文件报404 Not Found错误， 访问静态资源是可以正常访问返回码200。 

查看容器日志

1.  
   [root@hecs-136019 ~]# more /data/docker/nginx/logs/error.log

根据日志反馈，定位问题：

1、nginx与php-fpm容器网络不通

2、nginx、php-fpm配置文件

验证：

1、查看网络是否连通

1.  
   [root@hecs-136019 ~]# docker exec -it 34f07196ec86 /bin/bash
2.  
   [root@34f07196ec86 html]# ping 172.17.201.8
3.

 查看php-fpm容器IP

1.  
   root@hecs-136019 ~]# docker inspect nginx-php-fpm | grep IPAddress
2.  
   "SecondaryIPAddresses": null,
3.  
   "IPAddress": "",
4.  
   "IPAddress": "172.17.201.8",

查看nginx容器IP

1.  
   [root@hecs-136019 ~]# docker inspect 34f07196ec86 | grep IPAddress
2.  
   "SecondaryIPAddresses": null,
3.  
   "IPAddress": "",
4.  
   "IPAddress": "172.17.201.6",
5.  
   [root@hecs-136019 ~]#

查看nginx配置， 开启php模块， 把fastcgi_pass 地址更改为php容器的地址  IP:端口
