3.安装kubesphere

1.本地存储动态 PVC

# 在所有节点安装 iSCSI 协议客户端（OpenEBS 需要该协议提供存储支持）
yum install iscsi-initiator-utils -y
# 设置开机启动
systemctl enable --now iscsid
# 启动服务
systemctl start iscsid
# 查看服务状态
systemctl status iscsid

# 安装 OpenEBS 
kubectl apply -f https://openebs.github.io/charts/openebs-operator.yaml

# 查看状态（下载镜像可能需要一些时间）
kubectl get all -n openebs

# 在主节点创建本地 storage class
kubectl apply -f default-storage-class.yaml

2.安装

# 安装资源
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.3.1/kubesphere-installer.yaml
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.3.1/cluster-configuration.yaml

# 检查安装日志
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f

# 查看端口
kubectl get svc/ks-console -n kubesphere-system

# 默认端口是 30880，如果是云服务商，或开启了防火墙，记得要开放该端口

# 登录控制台访问，账号密码：admin/P@88w0rd
