How can i remove safely and completely a from source installed version of mysql(it's not a rpm or pkg version)??

Can i delete certain directories and all mysql related files??

Thanks

Yes....
I have not done this in a quite a while. But use locate to find mysql related files/directories.

locate mysql


This will give you a start. Also check for my.cnf files in /etc.

Unless you installed something odd -- all mysql directories should be able to be deleted without problems. However, if you are unsure, I make a tarball of the files first and then delete them. If there are problems, put the files back.
