HI people,
I am using centos 5 and I am confused on what file to put in my yum.repo.d to update my centos.
do you mean "update", or "upgrade" ??
update simply means to install whatever fixes/enhancements have been released for Centos 5. you still end up with Centos 5, but it has all the various fixes/enhancements Centos has made available for it. You can do the "update" by simply becoming root (in a terminal, "su -" and enter root's password) then type in "yum update". that's it.
upgrade means to go to Centos-6 or Centos-7. Until recently, there has been no centos-blessed upgrade mechanism (though in earlier versions I have used the installer's upgrade mode, it was always suggested not to do so because things could go bad in a hurry).
The recommended method of doing a system upgrade was to back up ALL your data, install the new version over the prior one, then restore your data. there is a new upgrade tool now, and some people have tested it, but I'm not sure if it is officially approved, yet, or not. And, unfortunately, I don't remember what it's called.
