Hi there,

I want to change my yum repository to RHEL 5 repository from RHEL 6 is this possible if so how do I go about doing it?

The reason I am doing this is because I have downloaded and installed a previous version of MySQL but they only had RHEL5.rpm. Now when I try to install Percona toolkit I get dependency errors and trying to downloading and finding rpm's for those dependency's seems to be a hard task.

There is no option to take down MySQL and upgrade as the server is a live server and is the Master in replication configuration.

Would be grateful for any help thanks in advance.

Alex.

You're going to work around installing the wrong packages by going on to install more and more and more incorrect packages?? I think it's possible, but you'd need to do some fairly offensive tricking of RHN into thinking your system is something it isn't. If it HAS to be done then I would just manually find the RPM's one by one. I wouldn't want to deliberately wreck yum / rhn.

At some point you'll hit a really nasty dependency and find you're being told your version of glibc is incompatible or something. Do the right thing and fix MySQL somehow.

Thanks for the quick reply I was afraid you may say that, I cant't really change MySQL seeing as we need the specific version 5.1.44 and that doesn't exist for RHEL6.

I guess I'll have to try work around it but as you said I think I will hit some nasty dependency.

why do you need that specific version?

Because the MySQL replication slaves use that version and a MYSQL replication master needs either the same MySQL version or lower in order for replication to be at it's best.
