Compile Version of Linux Kernel 5.10.x
ELRepo Project The kernel version provided has always been relatively stable, and kernel-ml has always provided the rpm installation package of the latest version of the kernel.
But kernel-ml always no longer provides the old version after the new major version comes out. Kernel-lt is still updating the previous longterm version 5.4 and has not switched to the latest longterm version 5.10.
Kernel-ml branches 5.10 to 5.10.16 will no longer be updated.
So I wondered if I could compile it myself, and I took this opportunity to learn how the ELRepo Project compiles the Linux kernel.
After finding the old versions of kernel-ml-5.10.16-1.el7.elrepo.nosrc.rpm and kernel-ml-5.10.16-1.el8.elrepo.nosrc.rpm, the tossing process can be skipped. mentioned. In short, the latest version of 5.10.x is compiled based on this.

After the download is complete, execute the following command to install:
# yum localinstall kernel-ml-*
After successful installation, execute the following command to view the list of kernels that already exist on this machine:
# awk -F\' '$1=="menuentry " {print i++ " : " $2}' /boot/grub2/grub.cfg
Return value example:
0 : CentOS Linux (5.10.170-1.el7.x86_64) 7 (Core) 1 : CentOS Linux 7 Rescue b2206184ea3c4d8a9be703c8e6b739ab (3.10.0-1127.13.1.el7.x86_64) 2 : CentOS Linux (3.10.0-1127.13.1.el7.x86_64) 7 (Core) 3 : CentOS Linux (0-rescue-00a62363617944e08db8db894ba6145e) 7 (Core)
Set to start the latest kernel (generally the latest installed kernel boot order is 0)
# grub2-set-default 0
Delete the rpm file.
# rm -fv kernel-ml-*
after that reboot Restart the system and enter the system again, which will be the latest version of the kernel.
