Install grsecurity from 3rd party repo

From FiberWiki

Repo

We will need to paste this information under the /etc/yum.repos.d folder. We will name it grsecurity.repo so that it will be easily located later on.

cd /etc/yum.repos.d
nano grsecurity.repo

Paste the following information:

# Yum Repository file for grsecurity by Corey Henderson
# This particular file is for enterprise linux (RHEL, CentOS, etc)
#
# To use this repository, put this file in: /etc/yum.repos.d/
#
# For more RPM repositories from this packager, go to:
# http://rpm.cormander.com/repo/

name=Stable grsecurity kernel
baseurl=http://rpm.cormander.com/repo/grsec/kernel-stable/$basearch/
gpgcheck=1
gpgkey=http://rpm.cormander.com/repo/RPM-GPG-KEY-cormander

Now we need to exit the editor:

Ctrl+x
y
[enter]

Yum

Now we can use yum to install a pre-compiled grsecurity kernel!

yum install kernel-grsec

After yum has finished you may now reboot and switch to grsecurity kernel!
