(1)检测ELRepo是否安装

yum --disablerepo="*" --enablerepo="elrepo-kernel" list available

(2)安装ELRepo

centos6 使用

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org 
rpm -Uvh https://www.elrepo.org/elrepo-release-6-8.el6.elrepo.noarch.rpm 

centos7 使用

rpm -Uvh https://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm 

2.升级内核

yum --disablerepo="*" --enablerepo="elrepo-kernel" list available 

yum --enablerepo=elrepo-kernel install kernel-lt

3.查看是否成功

rpm -qa | grep -i kernel
