回答1:

Looks as if your database file is locked by another process, did you try restarting the machine?

回答2:

Just for notes. In my case, after I create db with:

sudo mkdir -p /data/db

I also have to do this:

sudo chmod 777 /data/db

Then the environment is up for running by entering:

mongod

to enter the mongoldb shell.
