    4. Thanks for the instructions. I just upgraded a fresh CentOS 5.3 install up to CentOS 5.5 final. I followed your instructions exactly and they worked perfectly.

      I had been using Fedora before (way back on Fedora 7). I tried to upgrade through a few Fedora versions, but I decided it was time for the nightmare to end. It’s almost a shock that the same company that makes Fedora is really behind CentOS (Fedora = Beta, Redhat=Paid, CentOS=Free Redhat Clone w/out Support).

      Anyway, thanks for the post. It worked like a charm.

    9. Hi,

      Just done an upgrade from 5.3 to 5.4 using the above process (thanks! )

      It won’t upgrade any further than 5.4. How do I get it to go to 5.5 or above? I’ve tried yum clean all, and repeating the above process, but it just says nothing to upgrade.

      Cheers,

      Darren.

    13. Standard newbie excuse here. Does “yum update” update applications such as apache, php and mysql such that I might end up with compatability issues with my php webpages?

      Additional question: when “yum list updates” for examples shows “php.i386 5.1.6-40.el5_9 updates” is that where I am now, our where I will be if the update suceeds?

      • Hi Alf,

        Yes it’s of course possible, that updating applications like apache, php, mysql breaks your php code (this totally depends on your code). So it’s important to know are you updating php from 5.1 to 5.5 or are you updating just minor versions, like from 5.1.6 to 5.1.7 or even just some new build, like 5.1.6-37 to 5.1.6-40.

        Yum list updates shows new version, but if you use following command:

        
        yum list php httpd mysql
        

        Then you should see installed and available versions, so yum update your package from installed version to available version.

        You can of course “pin” package versions (using /etc/yum.conf) or exclude some packages from upgrade process, if you want, but normally RHEL/CentOS 5 updates are important security updates.

        If you need more help, feel free to ask.

    14. Thank you for that clear explanation. My experience with computers has been that the chances of a failed upgrade is exponentially proportional to the number of modules times the number of revisions to go.
      So does your experience indicate “yum update” from 5.2 to 5.9 has a good chance of success?

      Thanks again.

      • Hi Alf,

        Sorry for the late reply, but I think you have a good change of success, when you upgrade from 5.2 to 5.9. You should of course backup your important stuff first.
