Centos7 快速部署k8s 1.27版本（一定要升级内核，因为cilium需要）

关闭selinux(一定要做)

关闭防火墙(推荐关闭)

安装内核

wget https://dl.lamp.sh/kernel/el7/kernel-ml-5.10.222-1.el7.x86_64.rpm
wget https://dl.lamp.sh/kernel/el7/kernel-ml-devel-5.10.222-1.el7.x86_64.rpm

yum localinstall -y kernel-ml-5.10.222-1.el7.x86_64.rpm kernel-ml-devel-5.10.222-1.el7.x86_64.rpm
#安装完毕后查看系统可用启动内核
awk -F\' '$1=="menuentry " {print  $2}' /etc/grub2.cfg

查看当前内核

grub2-editenv list
#修改默认内核CentOS Linux (5.10.222-1.el7.x86_64) 7 (Core)是awk查询出来的内核名称
grub2-set-default 'CentOS Linux (5.10.222-1.el7.x86_64) 7 (Core)'	

重新启动

reboot

查看内核

uname -r
