用yum升级centos6.4内核

一、导入官方Key

[root@i-ylibhc7r ~]# rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

二、升级指定的内核，下载官方源

[root@i-ylibhc7r ~]# wget http://hkg.mirror.rackspace.com/elrepo/kernel/el6/x86_64/RPMS/kernel-lt-4.4.101-1.el6.elrepo.x86_64.rpm

小结：这里给大家介绍的是香港的kernel源，下载速度很快，一般比官方也就慢个2天左右更新。

三、安装kernel的rpm包
[root@i-ylibhc7r ~]# yum install -y kernel-lt-4.4.101-1.el6.elrepo.x86_64.rpm
