这篇文章主要介绍了Kubekey安装Kubernetes-1.24.8的详细过程，本文给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下
Kubekey简介
官网文档：https://kubesphere.com.cn/docs/v3.3/installing-on-linux/introduction/kubekey/
Github：https://github.com/kubesphere/kubekey
Github中文文档：https://github.com/kubesphere/kubekey/blob/master/README_zh-CN.md
Kubekey采用Go编写，不像Ansible那样依赖运行环境，可以同时安装 Kubernetes 和 KubeSphere。此外Kubekey还可以对K8S集群做升级、扩缩容、根据Yaml安装插件等操作，对非专业运维的开发人员相当友好。

- 完成环境：kubernetes-1.24.8,容器:containerd
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
sed -i 's/enforcing/disabled/' /etc/selinux/config setenforce 0 cat /etc/selinux/config
6.关闭 swap-所有节点
swapoff -a sed -ri 's/.*swap.*/#&/' /etc/fstab free -l -h
7.安装依赖组件### 安装依赖组件-所有节点
yum install -y ebtables socat ipset conntrack
8.安装其他依赖于时间同步-所有节点
yum install -y ebtables socat ipset conntrack
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
