1:环境初始化
1：分别在4台主机设置主机名称
hostnamectl set-hostname node01
hostnamectl set-hostname node02
hostnamectl set-hostname node03
hostnamectl set-hostname node04
2:配置主机映射
cat <<EOF > /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.150.181 node01
192.168.150.182 node02
192.168.150.183 node03
192.168.150.184 node04
EOF
3：node01上执行ssh免密码登陆配置
ssh-keygen #一路回车即可
ssh-copy-id node02
ssh-copy-id node03
ssh-copy-id node04
4：四台主机配置、停防火墙、关闭Swap、关闭Selinux、设置内核、K8S的yum源、安装依赖包、配置ntp（配置完后建议重启一次）
systemctl stop firewalld
systemctl disable firewalld
swapoff -a
sed -i 's/.*swap.*/#&/' /etc/fstab
setenforce 0
sed -i "s/^SELINUX=enforcing/SELINUX=disabled/g" /etc/sysconfig/selinux
sed -i "s/^SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
sed -i "s/^SELINUX=permissive/SELINUX=disabled/g" /etc/sysconfig/selinux
sed -i "s/^SELINUX=permissive/SELINUX=disabled/g" /etc/selinux/config
modprobe br_netfilter
cat <<EOF > /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
sysctl -p /etc/sysctl.d/k8s.conf
ls /proc/sys/net/bridge
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
