准备工作
请注意开始前工作确定各个软件版本情况，本文章要想阅读比较舒服请还得有些Go开发经验
- CentOS 7.9
- KubeKey v1.21
- KubeSphere v3.2.1
Docker 和 Kubernetes 根据支持进行选择：
获取支持可以通过如下命令：
./kk version --show-supported-k8s
v1.15.12
v1.16.8
v1.16.10
v1.16.12
v1.16.13
v1.17.0
v1.17.4
v1.17.5
v1.17.6
v1.17.7
v1.17.8
v1.17.9
v1.18.3
v1.18.5
v1.18.6
v1.18.8
v1.19.0
v1.19.8
v1.19.9
v1.20.4
v1.20.6
v1.20.10
v1.21.4
v1.21.5 (我测试选择的版本)
v1.22.1
开始前必须准备
请认真阅读对应官方的几个文档说明
Documentation (kubesphere.com.cn)
根据自己的安装选择进行阅读，注意准备干净的机器环境
在开始进行安装前可以不安装Docker kk 都会帮解决

依赖说明，在刚安装好的 CentOS机器上会提示：socat、conntrack 必须条件要安装
yum -y install socat conntrack-tools
关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
单机安装
https://kubesphere.com.cn/docs/quick-start/all-in-one-on-linux/
单机安装一般没有什么坑，一般比较顺畅。
./kk create cluster --with-kubesphere v3.2.1
多机安装
多节点安装 (kubesphere.com.cn)
./kk create cluster -f sample.yaml --with-kubesphere v3.2.1
遇到的坑
不部署 KubeSphere ，只是部署 Kubernetes
1.根据文档进行如下命令进行部署，多次发现 KubeSphere 一直没有部署成功。Docker ps 中进程也少
./kk create cluster -f sample.yaml
部署中提示到 Congratulations! Installation is successful. 进行技术
经过源码查证后发下如下：
- 查看 Congratulations! Installation is successful. 出现位置
mgr.Logger.Infoln("Congratulations! Installation is successful.")
网上看发现
if mgr.KsEnable && !noNetworkPlugin
``
执行 else 才会进行打印
2.确认网络是否启动 noNetworkPlugin
```golang
noNetworkPlugin := mgr.Cluster.Network.Plugin == "" || mgr.Cluster.Network.Plugin == "none"
查看代码发现和网络插件有关，已经配置啦
network:
plugin: calico
kubePodsCIDR: 10.233.64.0/18
kubeServiceCIDR: 10.233.0.0/18
3.推出只有 mgr.KsEnable ，然后，本地进行代码调试发现。执行结果确实是 false 是不是有些坑，因此开始寻找 KsEnable 如何赋值
// pkg\util\executor\executor.go
mgr.KsEnable = executor.Cluster.KubeSphere.Enabled
// pkg\cluster\install\install.go
// Execute executes the tasks based on the parameters in the Manager.
func Execute(executor *executor.Executor) error {
mgr, err := executor.CreateManager()
if err != nil {
return err
}
return ExecTasks(mgr)
}
// 找到出现位置啦 ksEnabled
// CreateCluster is used to create cluster based on the given parameters or configuration file.
func CreateCluster(clusterCfgFile, k8sVersion, ksVersion string, logger *log.Logger, ksEnabled, verbose, skipCheck, skipPullImages, inCluster, deployLocalStorage bool, downloadCmd, containerManager string) error
// 找到啦，结果知道如果执行啦
// cmd
clusterCmd.Flags().BoolVarP(&opt.Kubesphere, "with-kubesphere", "", false, "Deploy a specific version of kubesphere (default v3.2.0)")
最终执行命令行为
./kk create cluster -f sample.yaml --with-kubesphere v3.2.1
