Upgrading CentOS 7’s Kernel

CentOS is known for its stability and reliability, but for those of you who are interested here is how to upgrade you kernel in CentOS 7

First,  we’ll add the ELRepo GPG key:

rpm –import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

Next, we’ll need to add the ELRepo:

rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm

It should already be enabled, but if it is not then well need to add it. Enter this in your terminal session:

yum install yum-plugin-fastestmirror

To check your current Kernel version type:

uname -r

your output should look like: 3.10.0-(more numbers).x86_64

For this next part, you will need to reboot your computer or server and then select the new kernel. (The very top one)
