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。

nginx与php-fpm容器网络不通
nginx、php-fpm配置文件
验证：
查看网络是否连通

查看php-fpm容器IP
root@hecs-136019 ~]# docker inspect nginx-php-fpm | grep IPAddress "SecondaryIPAddresses": null, "IPAddress": "", "IPAddress": "172.17.201.8",查看nginx容器IP
[root@hecs-136019 ~]# docker inspect 34f07196ec86 | grep IPAddress "SecondaryIPAddresses": null, "IPAddress": "", "IPAddress": "172.17.201.6",[root@hecs-136019 ~]# | 容器 | IP |
| nginx | 172.17.201.6 |
| php-fpm | 172.17.201.8 |
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

[www]; The address on which to accept FastCGI requests.; Valid syntaxes are:; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific address on;a specific port;; 'port' - to listen on a TCP socket to all addresses on a;specific port;; '/path/to/unix/socket' - to listen on a unix socket.; Note: This value is mandatory.listen = 0.0.0.0:9000 # 监听所有服务器的9000端口（默认是本机127.0.0.1:9000）; Set listen(2) backlog. A value of '-1' means unlimited.; Default Value: -1;listen.backlog = -1; List of ipv4 addresses of FastCGI clients which are allowed to connect.; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address; must be separated by a comma. If this value is left blank, connections will be; accepted from any ip address.; Default Value: anylisten.allowed_clients = 172.17.201.6 #更改为nginx容器的IP（默认是本机127.0.0.1）; Set permissions for unix socket, if one is used. In Linux, read/write; permissions must be set in order to allow connections from a web server. Many; BSD-derived systems allow connections regardless of permissions.; Default Values: user and group are set as the running user; mode is set to 0666;listen.owner = nobody;listen.group = nobody;listen.mode = 0666; Unix user/group of processes; Note: The user is mandatory. If the group is not set, the default user's group; will be used.; RPM: apache Choosed to be able to access some dir as httpduser = apache; RPM: Keep a group allowed to write in log dir.group = apache重启服务
