使用KubeKey快速部署k8s v1.31.8集群
实战环境涉及软件版本信息：
使用kubekey部署k8s
1. 操作系统基础配置
设置主机名、DNS解析、时钟同步、防火墙关闭、ssh免密登录等等系统基本设置
dnf install -y curl socat conntrack ebtables ipset ipvsadm
2. 安装部署 K8s
2.1 下载 KubeKey
###地址
https://github.com/kubesphere/kubekey#下载最新版的 KubeKey
export KKZONE=cn ####国内用户先执行此配置mkdir ~/kubekey
cd ~/kubekey
curl -sfL https://get-kk.kubesphere.io | sh -

生成配置文件
./kk create config -f k8s-v1318.yaml --with-kubernetes v1.31.8
2.2 创建 K8s 集群部署配置文件
修改配置文件
采用 3 个节点同时作为 control-plane、etcd 和 worker 节点。
编辑配置文件 k8s-v1288.yaml，主要修改 kind: Cluster 小节的相关配置
修改 kind: Cluster 小节中 hosts 和 roleGroups 等信息，修改说明如下。
hosts：指定节点的 IP、ssh 用户、ssh 密码、ssh 端口
roleGroups：指定 3 个 etcd、control-plane 节点，复用相同的机器作为 3 个 worker 节点
internalLoadbalancer：启用内置的 HAProxy 负载均衡器
domain：可自定义域名
clusterName：可使用默认值 cluster.local
autoRenewCerts：该参数可以实现证书到期自动续期，默认为 true
containerManager：使用 containerd
部署完成需要大约 10-20 分钟左右，会在终端上看到类似于下面的输出。
安装的时候最好走代理，因为大部分包在国外，不走代理慢到哭，首先要让服务器走代理
cat << 'EOF' > /etc/profile.d/proxy.sh
export HTTP_PROXY="http://ip"
export HTTPS_PROXY="http://ip"
export NO_PROXY="127.0.0.1,localhost,ip,10.233.0.0/18,10.233.64.0/18"
EOF

执行安装，安装时长看网速
