Resolves MongoDB failed to start under Ubuntu, prompting couldn ' t remove FS lock errno:9 Bad file descriptor error _MONGODB

According to the official website installation method:

The following error may occur under the Ubuntu system:

Couldn ' t remove FS lock errno:9 Bad file descriptor

The file owner needs to be modified at this time

$ sudo mkdir-p/data/db/

$ sudo chown ' USERNAME '/data/db

The first sentence is to create your database folder, the second sentence to modify the owner of the folder

Then you can start the MongoDB successfully.
