前置默认都安装了k8s，且k8s都正常
1、nfs文件系统
1.1、安装nfs-server
# 在每个机器。
yum install -y nfs-utils# 在master 执行以下命令
echo "/nfs/data/ *(insecure,rw,sync,no_root_squash)" > /etc/exports# 执行以下命令，启动 nfs 服务;创建共享目录
mkdir -p /nfs/data# 在master执行
systemctl enable rpcbind
systemctl enable nfs-server
systemctl start rpcbind
systemctl start nfs-server# 使配置生效
exportfs -r#检查配置是否生效
exportfs
1.2、配置默认存储
- 创建nfs.yam文件
vi nfs.yaml- 根据自己的情况，更改文件内容即可
## 创建了一个存储类
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:name: nfs-storageannotations:storageclass.kubernetes.io/is-default-class: "true"
provisioner: k8s-sigs.io/nfs-subdir-external-provisioner
parameters:archiveOnDelete: "true" ## 删除pv的时候，pv的内容是否要备份---
apiVersion: apps/v1
kind: Deployment

kubectl apply -f nfs.yaml
2、安装kubesphere
- 下面操作主节点执行即可
2.1、下载核心文件
wget https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/kubesphere-installer.yamlwget https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/cluster-configuration.yaml
2.2、修改
- 需要指定下etcd服务IP，一般为master节点的IP
- cluster-configuration.yaml包含了kubesphere工具，默认都是false，在安装kubesphere时不会安装这些工具，我们可以选择想要安装的工具，改为true即可
- 配置低的话，不建议在安装时去同步安装工具
2.3、执行安装
kubectl apply -f kubesphere-installer.yamlkubectl apply -f cluster-configuration.yaml
- 注意：电脑配置一定要满足官方的最低要求，否则安装会不成功！
2.4、查看安装进度
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f
- 安装时间会有点长，建议用上面命令查看
- 安装成功截图如下：
- 也可以查看service的生成状态，下面这个是成功后的service列表
kubectl get svc -A
2.5、登录
地址：http://k8s节点的IP:30880
账号：admin
密码：P@88w0rd
