[問題解決] 啓動mongod 時，出現addr already in use錯誤

錯誤：

啓動mongod  

 root@wangyuyu-Vostro-1440:/usr/bin# ./mongod

錯誤提示：

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

緣由：

啓動mongod時端口被佔用。

 

解決方案：

使用命令 

root@wangyuyu-Vostro-1440:/usr/bin# netstat -anp|more

能夠看到客戶端還保持着與服務器的鏈接

殺死953進程

root@wangyuyu-Vostro-1440:/usr/bin# kill -9 953

再次察看服務器連接狀態：
