Sometimes when some services are installed on the server to meet daily needs, they often give up because of the kernel. This blog post is to solve this problem.

Implementation steps:

[root@localhost ~] # uname-r / / View system kernel 3.10.0-862.el7.x86_64 [root@localhost ~] # rpm-- import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org// load public key [root@localhost ~] # rpm-Uvh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm// install import [root] @ localhost ~] # yum-- disablerepo=\ *-- enablerepo=elrepo-kernel repolist// loads elrepo-kernel metadata [root@localhost ~] # yum-- disablerepo=\ *-- enablerepo=elrepo-kernel list kernel*// to view available rpm packages [root@localhost ~] # yum-- disablerepo=\ *-- enablerepo=elrepo-kernel install-y kernel-ml.x86_64// installs the latest version of kernel

Restart and it will appear as shown in the figure:

[root@localhost ~] # yum-y remove kernel-tools-libs.x86_64 kernel-tools.x86_64 / / remove the old version of the toolkit [root@localhost ~] # yum-- disablerepo=\ *-- enablerepo=elrepo-kernel install-y kernel-ml-tools.x86_64// install the new version of the toolkit [root@localhost ~] # uname-r / / View the current system version kernel 5.4.5-1.el7.elrepo.x86 _ 64 [root@localhost ~] # rpm-qa | grep kernel / / query all cores in the system [root@localhost ~] # yum remove-y kernel-3.10.0-862.el7.x86_64 / / remove redundant kernels

After restart, as shown in the figure:
