Hello CentOS users,
Currently I have compiled kernel version 4.19.37, which the source is from kernel.org. I compiled the kernel by following
steps:
- get the kernel tarball and unpack it
- install prerequisties as described in https://wiki.centos.org/HowTos/Custom_Kernel (in addition bc and openssl-devel)
- copy the kernel configuration:
$ cp /boot/config-3.10.0-957.21.3.el7.x86_64 ~/linux-4.19.37/.config
- create configuration:
$ cd ~/linux-4.19.37
$ make olddefconfig
$ make nconfig
- compile and create RPM package:
$ make vmlinux
$ make modules
$ make rpm-pkg
- install kernel RPM:
# yum install ~/rpmbuild/RPMS/x86_64/kernel-*.rpm
However, in the last step (installing kernel RPM), I got following notice:
================================================================================

Install 3 Packages
There, the compiled kernel-headers package (4.19.37_sentinel_custom-1) is about to replace stock version
(3.10.0-957.21.3.el7). Is it safe to continue installing from compiled RPM package above, or install kernel manually?
