更换内核

rpm -ivh http://linuxsoft.cern.ch/cern/centos/7/updates/x86_64/Packages/kernel-3.10.0-229.1.2.el7.x86_64.rpm --force

设置我们要的内核启动(只有在升级了内核时才需要)

grub2-set-default "CentOS Linux (3.10.0-229.1.2.el7.x86_64) 7 (Core)"

禁止更新内核

yum install -y nano
nano
#[main]最后面加入
exclude=kernel*
exclude=centos-release*
#Ctrl+X退出并按提示保存

剩下的91什么的，选择匹配低的
