启动mongod:
root@wangyuyu-Vostro-1440:/usr/bin# ./mongod
错误提示:
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。

杀死953进程:root@wangyuyu-Vostro-1440:/usr/bin# kill -9 953
再次查看服务器连接状态:
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN 1546/dnsmasq tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN 653/cupsd tcp 0 0 192.168.5.124:60805 61.172.207.130:80 TIME_WAIT - tcp 1 0 192.168.5.124:56874 91.189.89.144:80 CLOSE_WAIT 1913/ubuntu-geoip-p tcp 0 0 192.168.5.124:54370 117.79.157.237:80 TIME_WAIT -
OK,已经成功杀掉进程。
