报错1：

[ftdc] Unclean full-time diagnostic data capture shutdown detected, found interim file, some metrics may have been lost.

解决办法：

1、删除掉diagnostic数据：

rm -f /var/lib/mongo/diagnostic.data/*

2、启动mongodb。

进入MongoDB的bin目录下，

sudo ./mongod

报错2：

2018-07-20T22:42:08.645+0800 I STORAGE  [initandlisten] exception in initAndListen: DBPathInUse: Unable to lock the lock file:

(Unknown error). Another mongod instance is already running on the /data/db directory, terminating.

2018-07-20T22:42:08.645+0800 I CONTROL  [initandlisten] now exiting
2018-07-20T22:42:08.645+0800 I CONTROL  [initandlisten] shutting down with code:100

解决办法：mongodb非正常关闭删除mongod.lock文件即可.(lock文件所在路径各有不同)

sudo rm /data/db/mongod.lock

报错3：

2018-07-20T22:29:17.982+0800 I CONTROL  [initandlisten] MongoDB starting : pid=3499 port=27017 dbpath=/data/db 64-bit host=xumovm

......

2018-07-20T21:12:05.974+0800 E STORAGE  [initandlisten] Failed to set up listener: SocketException: Address already in use

解决办法：

找到mongo之前运行的PID号，关掉它，重新输入启动命令

sudo netstat -anp|more
激活Internet连接 (服务器和已建立连接的)
Proto Recv-Q Send-Q Local Address           Foreign Address         State      
 PID/Program name    
tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN     
 2515/./mongod       

sudo kill 2515

正确的关闭方法：停止Mongodb

方法一：查看进程，使用kill命令；不能使用kill -9

方法二：在在客户端进去，使用shutdown命令

/usr/local/mongodb/bin:$ ./mongod
> use admin; 
switched to db admin 
> db.shutdownServer();
 server should be down...

1、新安装mongodb，执行sudo service mongod start（sudo service mongod restart），都报启动失败。

查看/var/log/mongodb/mongod.log：

解决步骤：

  1、删除日志文件/var/log/mongodb/mongod.log

rm /var/log/mongodb/mongod.log

  2、删除lock文件

rm /var/log/mongodb/mongod.log

  3、执行修复

sudo /usr/bin/mongod –repair –dbpath /var/lib/mongodb / –repairpath /tmp/mongodb

4-最终方式：重启服务器端

reboot
