Changing 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)

Once the system is back up, login and check to see what the kernel version is.  It should be 4.13.5 or a newer version.
