How to Free Up Space in /boot on CentOS Server

Asked by bitmap
I have a CentOS box at home and I’m trying to install the latest Kernel but it is failing as my /boot partition is too small and there’s not enough space.
Can I just use rm and delete some of the old Kernels stored in there? Or do I have to resize the partition so that I could have more space? Or is there a better way to sort that out?
Thank you!

Please note that you would need to reboot your server in order for the change to take effect.
To check your system information you could then simply run:
