启动mongod：
1 | root@wangyuyu-Vostro-1440:/usr/bin# ./mongod
|
错误提示：
1 2 3 | Sat Aug 17 09:02:02 [initandlisten] ERROR: listen(): bind() failed errno:98 Address already in use for socket:
0.0.0.0:27017
Sat Aug 17 09:02:02 [initandlisten] ERROR: addr already in use
|
原因是启动mongod时端口被占用。
解决办法：
使用命令：root@wangyuyu-Vostro-1440:/usr/bin# netstat -anp|more
可以看到客户端还保持着与服务器的连接。
