linux - centos上mongo启动失败

Question

在centos6.5上安装mongo环境，步骤都没错，可是启动的时候报错，然后data文件夹里面什么也没有，log里的日志倒是有把日志信息都打进去。。下面是报错的，

看了mongod.log 报错的日志是：

2016-06-24T22:31:32.755+0800
 E NETWORK  [initandlisten] listen(): bind() failed errno:98
 Address already in use for socket: 0.0.0.0:27017

2016-06-24T22:31:32.755+0800
 E NETWORK  [initandlisten] addr already in use

2016-06-24T22:31:32.755+0800 
E STORAGE  [initandlisten]
 Failed to set up sockets during startup.
2016-06-24T22:31:32.755+0800 
I CONTROL  [initandlisten] dbexit:  rc: 48

弄了好久，卸了几次还是不行。。也没有网上说的什么lock文件。。。实在不懂是什么问题，麻烦知道的朋友解答一下、、真心谢谢QAQ

查看了27017端口

Answer 1

Can’t you understand such a simple error message? The port is occupied. Check whether port 27017 is occupied and see if you have started a mongod.

Answer 2

The listening port is occupied. Use netstat -nap|grep [port number to be used] to see which process is occupied, or change the mongo configuration file to listen to other ports.
