Quickly upgrade the CentOS 6.5 kernel to 3.10.28 using Yum

There are many articles on the Internet that upgrade the CentOS kernel, such as "CentOS 6.5 upgrade kernel to 3.10.28", most of them are compiled by download source code, a bit of trouble.

In the Elrepo source of Yum, there are 2 kernel versions of mainline (3.13.1), long-term (3.10.28), which are more stable and will be updated for a long time, so choose this version.

1. Import Public key

1	RPM --import HTTPS://www.elrepo.org/rpm-gpg-key-elrepo.org

2, install Elrepo to CentOS-6.5

1	RPM -ivh http://www.elrepo.org/elrepo-release-6-5.el6.elrepo.noarch.rpm

3, installation kernel-lt (lt=long-term)

1	Yum- -Enablerepo=Elrepo-kernel install kernel-lt -y

or install kernel-ml (ml=mainline)

1	Yum- -Enablerepo=Elrepo-kernel install kernel-ml -y

Confirm the location of the newly installed kernel, then set the default value (starting from 0), generally the newly installed kernel is in the first position, so set default=0.

5. Reboot to see the kernel version number

12	[root@dev ~]# uname-r 3.10.28-1.el6.elrepo.x86_64
