You can use some common database for the all loggedin users and check every time when one is going to login whther someone has loggedin with a same userid or not.

The obvious way is in your database have a field that tells you a person is logged in, and if they are, don't allow another login. The issue with this is, you cannot be sure to catch any event that tells you a person has logged out, so you should also store a timestamp every time that user requests a page and when you check if they are logged in, also check that to see if it's been long enough to assume it has expired.
