Hi Rajiv,

I'm curious. Whats the use case for this? I'm not sure I've ever see it done. While its technically possible, you loose a lot of the benefits of redundancy by having it on the same host machine. See this discussion over on DBA StackExchange:

http://dba.stackexchange.com/questions/545/is-it-unwise-to-run-replication-on-same-physical-server

How To Forge has a tutorial doing this by compiling two completely different mysql binaries:

I could also imagine doing it using lxc containers or docker.
