Linux – yum update kernel without removing old

centoskernellinuxrpmyum

When I yum update it wants to remove the oldest of the 3 kernel I have and upgrade to a new.

Is it possible to get yum not to remove old kernels?

In /etc/yum.conf set installonly_limit=3. Quoting from the documentation:

installonly_limit Number of packages listed in installonlypkgs to keep installed at the same time. Setting to 0 disables this feature. Default is ’0’. Note that this functionality used to be in the "installonly" plugin, where this option was altered via. tokeep. Note that as of version 3.2.24, yum will now look in the yumdb for a installonly attribute on installed packages. If that attribute is "keep", then they will never be removed.

Linux Bash – How to Sort du -h Output by Size

As of GNU coreutils 7.5 released in August 2009, sort allows a -h parameter, which allows numeric suffixes of the kind produced by du -h:

du -hs * | sort -h

If you are using a sort that does not support -h, you can install GNU Coreutils. E.g. on an older Mac OS X:

brew install coreutils
du -hs * | gsort -h

From sort manual:

-h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G)

Yum update to specific kernel version

You are on the right track. You just didn't specify the kernel version the way yum expects it. The correct command would be

yum install kernel-2.6.18-128.8.1.el5

(Note that kernel packages are not updates for each other, each of them is a separate install, and the old ones remain until you run "rpm -e".)
