You can easily run yum update command to updates everything but the kernel using the exclude directive. This option define list of packages to exclude from updates or installs. This should be a space separated list. Shell globs using wildcards * and ?) are allowed.
yum syntax to update all except Kernel
The syntax is:
yum --exclude=packgeName\* update
yum --exclude=packgeName1\* --exclude=packgeName2\* update
yum -x 'packageName*' update
yum -x 'packageName1*' -x 'packageName2*' update
Examples
To prevent yum command from updating the Kernel type:
yum -y --exclude=kernel\* update |
OR
yum -y -x 'kernel*' update |
How do I prevent yum from Updating the Kernel permanently?
Edit /etc/yum.conf file, enter:
# vi /etc/yum.conf
Append/modify exclude directive line under [main] section, enter:
exclude=kernel*
Save and close the file. Now, you can just run the following without passing the -x or –exclude option to yum command:
# yum -y update

It suggest leaving out the ‘-y’ option in the example or at least explain its use lest someone expecting to be prompted ends up surprised.
Thanks it is useful article, I agree with Chris if we do without -y then we can verify the packages.

Eg: if there are around 200 packages now who to upgrade them at once. kindly reply me
I tried this on a vm, unfortunately the kernel was still updated anyway.
