Update CentOS 7 kernel in OVH

I need to update newer version of CentOS 7 kernel to allow my server to use Docker with OverlayFS.

Identify the server kernel

uname -r

Navigate to the boot directory

cd /boot

Download the kernel

wget https://last-public-ovh-kernel.snap.mirrors.ovh.net/builds/4.9.185/799710/bzImage/4.9.185-xxxx-std-ipv6-64/bzImage-4.9.185-xxxx-std-ipv6-64

Regenerate grub2

grub2-mkconfig -o /boot/grub2/grub.cfg

Reboot the server

reboot
