解决启动mongod 时，出现addr already in use错误

./mongod --dbpath /www/mongo/shard --journal --port 6717 --oplogSize 20000 --logpath /www/mongo/logs/mongodb.log --logappend --fork

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

再次察看服务器链接状态：
