1、准备三台服务器

  • 4c8g （master）
  • 8c16g * 2（worker）
  • centos7.9
  • 内网互通
  • 每个机器有自己域名
  • 防火墙开放30000~32767端口

2、使用KubeKey创建集群

1、下载KubeKey

  1. export KKZONE=cn
  4. curl -sfL https://get-kk.kubesphere.io | VERSION=v1.1.1 sh -
  6. chmod +x kk

2、创建集群配置文件

  1. ./kk create config --with-kubernetes v1.20.4 --with-kubesphere v3.1.1

3、创建集群

  1. ./kk create cluster -f config-sample.yaml

4、查看进度

  1. kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f
