I recently needed to set up multiple MySQL servers on a test computer to simulate a master-slave setup. I had never done this before, so I think it might be useful for others if I documented what occurred. This setup was done on a Linux server, however other platforms should operate similarly. I choose to use the "mysqld_multi" script to manage these instances. There is a way that you can compile the MySQL server with different network interfaces, but in my opinion, using "mysqld_multi" to manage activities is much easier.So shall we begin?
