docker容器连接问题：nginx 和 php-fpm --link后并无法正常解析php程序，求解。

1、我是这样建立容器的

php-fpm 容器

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

运行状态：

[root@4469e557bf9b src]# ps uax
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root         1  0.0  0.9 161684 19312 ?        Ss+  10:33   0:00 php-fpm: master process (/usr/local/php/etc/php-fpm.conf)

www          6  0.0  0.4 161684  8892 ?        S+   10:33   0:00 php-fpm: pool www
root         7  0.6  0.1  11784  2944 ?        Ss   10:49   0:00 /bin/bash
root        19  0.0  0.1  47432  3392 ?        R+   10:49   0:00 ps uax

nginx 容器

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

运行状态：

[root@b23d2b95cf6e /]# ps aux
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root         1  0.0  0.4  27236  8580 ?        Ss+  10:33   0:00 nginx: master process /usr/local/nginx/sbin/nginx -g daemon off;
www          5  0.0  1.5  51812 31316 ?        S+   10:33   0:00 nginx: worker process
www          6  0.0  1.5  51812 31316 ?        S+   10:33   0:00 nginx: worker process
root         7  0.7  0.1  11784  2796 ?        Ss   10:48   0:00 /bin/bash
root        20  0.0  0.1  47176  3324 ?        R+   10:48   0:00 ps aux

然而：
直接访问转发后的本地IP

➜  ~ curl -I http://10.8.150.44
HTTP/1.1 200 OK
Server: nginx
Date: Tue, 02 Aug 2016 10:52:02 GMT
Content-Type: text/html
Content-Length: 5
Last-Modified: Tue, 02 Aug 2016 05:53:26 GMT
Connection: keep-alive
ETag: "57a03556-5"
Accept-Ranges: bytes

访问PHP就报错了

➜  ~ curl -I http://10.8.150.44/index.php
HTTP/1.1 502 Bad Gateway
Server: nginx
Date: Tue, 02 Aug 2016 10:52:26 GMT

查看日志后错误代码

各位大神，求解到底哪里出错了，折磨了好几天啦。
