How to automatically keep only 3 kernels/headers at max in centos server

SarahGurung · 06-09-2015, 06:10 AM

Hello,

I have a centos server and has many kernels and the old kernels aren't deleted. I want only 3 kernels/headers to be present and want the old one to be deleted automatically. For this i did

Code:

vi /etc/yum.conf

and made

Code:

installonly_limit=3

.

But when i restarted the server and did

Code:

rpm -qa | grep kernel

it still showed the past five old kernels. Do i need to mnually remove it for that above changes to take place or did i go wrong somehere?
