K8s新版本搭建
文档参考：多节点安装 (kubesphere.com.cn) (opens new window)
# 1、准备环境
# 确保三台机能ping通
ping 10.0.2.23
ping 10.0.2.24
ping 10.0.2.25

# 确保三个节点都能相互访问
ssh 10.0.2.23
ssh 10.0.2.24
ssh 10.0.2.25

# 确保三个节点都能ping通外网
ping www.qq.com

# 安装工具
# docker这里就不展开说明
docker -v
# socat
yum -y install socat
# conntrack
yum -y install conntrack

# 时间同步
# 时间同步
timedatectl

发现时间跟我们的不一样
# 切换到上海
timedatectl set-timezone Asia/Shanghai

再次查看，发现本地时间已经切换到中国时间，并且三台机器的时间都是一样的。
yum -y install chrony
1
安装完后，查看一下时间同步服务器列表
chronyc -n sources -v
1
查看本机时间统统同步状态
chronyc tracking
1
核查本地时间
timedatectl status
1
可以看到三个机器是一样的了，如果要用到集群中某个机器为准点为时间机器，需要修改配置
# 2、下载pubkey
三台机器都能相互ping通后，接下来在master操作
curl -sfL https://get-kk.kubesphere.io | VERSION=v1.1.1 sh -
1
返回：
Downloading kubekey v1.1.1 from https://github.com/kubesphere/kubekey/releases/download/v1.1.1/kubekey-v1.1.1-linux-amd64.tar.gz ...
Kubekey v1.1.1 Download Complete!
为 kk 添加可执行权限：
chmod +x kk
1
# 3、创建集群
# 3.1、创建示例配件文件
./kk create config --with-kubernetes v1.19.8 --with-kubesphere v3.1.1
1
会在当前文件夹生成config.sample.yaml
# 3.2、配置文件
vi config-sample.yaml

# 3.3、开始安装
./kk create cluster -f config-sample.yaml

然后弹出输入yes，接下来耐心等待就OK。
整个安装过程可能需要 10 到 20 分钟，具体取决于您的计算机和网络环境。
# 4、验证安装
安装完成后，您会看到如下内容：
