I have MySQL Server version: 5.0.77-log Source distribution on a RHEL6 server.
I need to reinstall it on a second RHEL6 server to set up a testing environment but I cannot find where to download this exact version.
I was able to find the download at http://downloads.mysql.com/archives/community/.
However, to install it on RHEL6 requires downgrading many other core components. It's recommended to instead set up a RHEL5 server and install it there, if need be.
