Once you have logged on to mi-linux.wlv.ac.uk you can then access MongoDB

Starting MongoDB

Once logged into the server, you should see the Linux prompt:

csl-student$

MongoDB can be started in several ways from the Linux prompt:

First time

To start MongoDB type:

runMongo

This runs with a default password, that should be changed when you first login (see below).

The system should respond with:

Hello: yourStudentNumber
MongoDB shell version: 3.2.8
connecting to: 127.0.0.1:27017/dbyourStudentNumber
>

Any MongoDB command should be typed in at the > prompt.

With Password

Once you have changed your password, use instead:

runMongo yourPassword

Note: only run this from the Linux command line, not within MongoDB itself.

Using mongo directly

runMongo is a script file setup for your convenience that runs the mongo command and logs you into your own database.

If you need to use any of the other mongo options for any reason, you will need to run mongo directly:

mongo dbYourStudentNumber --port 27017 -u yourStudentNumber  -p yourMongoPassword -whatever_options_are_required

For example, if yourStudentNumber is 1612345 and MongoDB password is myMongoPwd then you would login as:

mongo db1612345  --port 27017 -u 1612345 -p myMongoPwd -whatever_options_are_required

Changing Password

Once you have logged into MongoDB successfully you can change the default password:

db.updateUser("myStudentNumber",
{
    pwd: "myNewPassword",
 }
);

Replacing myStudentNumber with your University student number and myNewPassword with your new password.

Note, the function names in MongoDB are case sensitive.

Exiting MongoDB

To leave MongoDB type:

exit
