Run multiple MySQL server on a single machine

Can we run multiple MySQL servers on a single machine?

Thanks.

From stackoverflow

• Yes, you just need to run them on separate ports and point them at different lib directories for their data.

  Here's a good reference: http://dev.mysql.com/doc/refman/5.1/en/mutiple-servers.html
