解决ubuntu16.04中mongodb远程连接不上的问题

系统版本：

• lsb_release -a
• No LSB modules are available.
• Distributor ID: Ubuntu
• Description: Ubuntu 16.04.2 LTS
• Release: 16.04
• Codename: xenial

MongoDB版本：

> db.version()
2.6.10

ps：使用yum安装的mongodb

1、查看网络端口情况，发现mongodb服务绑定中本地ip上

netstat -tunlp
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      -               
tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      -               
tcp6       0      0 :::22                   :::*                    LISTEN      -               
udp        0      0 0.0.0.0:60855           0.0.0.0:*                           -               
udp        0      0 127.0.1.1:53            0.0.0.0:*                           -               
udp        0      0 0.0.0.0:68              0.0.0.0:*                           -               
udp        0      0 0.0.0.0:631             0.0.0.0:*                           -               
udp        0      0 0.0.0.0:5353            0.0.0.0:*                           -               
udp6       0      0 :::44164                :::*                                -               
udp6       0      0 :::5353                 :::*                                -   

2、修改/etc/mongodb.con文件中mongodb绑定端口的ip，绑定到任何ip上：

bind_ip = 0.0.0.0

3、查看系统网络端口情况，mongodb服务监听的端口绑定中所有ip上，这样能够被内网的主机能够访问到

netstat -tunlp

tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      -

tcp6       0      0 :::22                   :::*                    LISTEN      -               
udp        0      0 0.0.0.0:60855           0.0.0.0:*                           -               
udp        0      0 127.0.1.1:53            0.0.0.0:*                           -               
udp        0      0 0.0.0.0:68              0.0.0.0:*                           -

udp        0      0 0.0.0.0:5353            0.0.0.0:*                           -               
udp6       0      0 :::44164                :::*                                -

4、使用内网的另外一台ubuntu系统机子：

输入 curl 192.168.31.172:27017 ，返回It looks like you are trying to access MongoDB over HTTP on the native driver port.

说明连接成功

或者中浏览器地址栏中输入http://192.168.31.172:27017/，enter后，回复上面相同的内容。
