1.hostname-所有节点

hostnamectl set-hostname l-master
hostnamectl set-hostname l-worker-01
hostnamectl set-hostname l-worker-02

2.hosts-所有节点

192.168.31.66   l-master
192.168.31.67   l-worker-01
192.168.31.68   l-worker-02

3.yum安装依赖-所有节点

yum install -y update 
yum install -y wget && yum install -y vim && yum install -y lsof && yum install -y net-tools

4.关闭防火墙-所有节点

systemctl stop firewalld
systemctl disable firewalld

5.关闭 selinux-所有节点

9.下载kk-master节点

mkdir /opt/kubesphere
cd /opt/kubesphere

export KKZONE=cn
curl -sfL https://get-kk.kubesphere.io | VERSION=v3.0.7 sh -

10.准备配置文件-master节点

cat /opt/kubesphere/k8s-config.yaml

11.执行安装-master节点

./kk create cluster -f k8s-config.yaml -y --container-manager containerd

12.验证-master节点

kubectl get pod -A
