linux - 连接到托管在 CentOS 上的 MongoDb 服务器失败

Question

Mongo 在 CentOs 机器上启动并运行

所有IP启用，无授权

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0

# security: none
# authorization: 'enabled

端口启用

netstat -tulnp
(No info could be read for "-p": geteuid()=1001 but you should be root.)
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 0.0.0.0:27017           0.0.0.0:*               LISTEN      -
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      -

使用 IP 从服务器本身进行的连接工作正常

mongo --host 10.X.X.16
MongoDB shell version v4.2.2
connecting to: mongodb://10.X.X.16:27017/?compressors=disabled&gssapiServiceName=mongodb
MongoDB server version: 4.2.2
Server has startup warnings:
2020-01-21T15:48:26.297-0800 I  CONTROL  [initandlisten]

在远程 Windows 机器上做同样的事情

mongo --host 10.X.X.16
MongoDB shell version v4.2.1
connecting to: mongodb://10.X.X.16:27017/?compressors=disabled&gssapiServiceName=mongodb
2020-01-21T15:59:07.563-0800 E  QUERY    [js] Error: couldn't connect to server 10.65.5.16:27017, connection attempt failed: NetworkTimeout: Error connecting to 10.X.X.16:27017 :: caused by :: Socket operation timed out :

谢谢!

问题已解决:

我不得不禁用 mongo 端口的防火墙

sudo firewall-cmd --zone=public --add-port=27017/tcp --permanent
sudo firewall-cmd --reload
