下载常用软件，需下载 socat
apt install -y screenfetch git wget net-tools vim openssh socat
2.5.1 安装
# 下载并安装sealos, sealos是个golang的二进制工具，直接下载拷贝到bin目录即可, release页面也可下载
wget -c https://sealyun.oss-cn-beijing.aliyuncs.com/latest/sealos && \
chmod +x sealos && mv sealos /usr/bin
# 下载离线资源包
wget -c https://sealyun.oss-cn-beijing.aliyuncs.com/05a3db657821277f5f3b92d834bbaf98-v1.22.0/kube1.22.0.tar.gz
# 安装一个三master的kubernetes集群

sealos clean --node 192.168.0.6-192.168.0.9 # 或者多个连续IP
2.5.6 清理集群
sealos clean --all
2.5.2 使用 kubeasz安装
使用纯净服务器，未安装过 docker k8s
安装
export release=3.0.0
wget https://github.com/easzlab/kubeasz/releases/download/${release}/ezdown
chmod +x ./ezdown
./ezdown -D
./ezdown -S
docker exec -it kubeasz ezctl start-aio
5.清理
以上步骤创建的K8S开发测试环境请尽情折腾，碰到错误尽量通过查看日志、上网搜索、提交issues等方式解决；当然你也可以清理集群后重新创建。
在宿主机上，按照如下步骤清理
- 清理集群
docker exec -it kubeasz ezctl destroy default - 清理运行的容器
./ezdown -C - 清理容器镜像
docker system prune -a - 停止docker服务
systemctl stop docker - 删除docker文件
umount /var/run/docker/netns/default
umount /var/lib/docker/overlay
rm -rf /var/lib/docker /var/run/docker
2.6 安装配置 zsh
apt-get install -y zsh

cat /etc/ssh/ssh*pub>>/home/ubuntu/.ssh/authorized_keys
cat /home/ubuntu/.ssh/authorized_keys >/root/.ssh/authorized_keys
chmod 644 /root/.ssh/authorized_keys
3.2 配置静态 IP
