    Installing an old Kernel

    Good Morning,

    Each of our RHEL5 Servers must be running the same Kernel, which is currently 2.6.18-164-11.1.el5.

    However, one of our servers is running 2.6.18-194.el5 and I need to be able to ensure that 2.6.18-164-11.1.el5 is installed on this server.

    I've checked and can see that there are no previous kernel versions available on this server. Please can you confirm if I can simply install 2.6.18-164-11.1.el5 on this server? If so is there anything that I need/should take into consideration?

    Help on this is much appreciated.

    Kind Regards
    Sharlene

    There isn't much changes in both kernels and I don't think you will any problem. I would suggest you to check change-log of kernels from 2.6.18-164-x.x to 2.6.18-194.x at kernel.org.
    It is amazing what you can accomplish if you do not care who gets the credit.

    Given that there have been a number of security updates to the kernel between 2.6.18-164 and the current/latest which is 2.6.18-194.26.1, I would recommend that you update the kernel on all of the systems. FWIW, the 2.6.18-164 kernel has been deprecated, and I can't even find it on any of the Red Hat or CentOS mirror sites. So, if you need to install the 2.6.18-164 kernel on the one machine because updating the others is not possible, then you will have to either copy the kernel and associated files to the machine you are going to downgrade, or you will have to build the kernel from sources, provided you have them.
    Sometimes, real fast is almost as good as real time.

    Notice that when you manually copy another kernel to your RHEL-box from a different box, you'll loose RedHat support!
