推荐答案

启动MongoDB的用户帐户需要对/data/db/目录具有写权限 ...您可以像这样更改所以...

The user account that is starting MongoDB needs to have write privileges to the /data/db/ directory ... you can change this like so ...

此命令会将/data/db/的所有者更改为所使用的用户帐户.

This command will change the owner of the /data/db/ to the user account being used.

$ sudo chown `id -u` /data/db
$ mongod 

如果启动MongoDB时仍然遇到问题，则需要删除/data/db/mongod.lock，然后对数据库进行修复...

If you still run into problems with MongoDB starting, you need to delete /data/db/mongod.lock and then run repair on your database ...

mongod --repair
