前置默認都安裝了k8s，且k8s都正常

1、nfs文件系統

1.1、安裝nfs-server

# 在每個機器。
yum install -y nfs-utils# 在master 執行以下命令 
echo "/nfs/data/ *(insecure,rw,sync,no_root_squash)" > /etc/exports# 執行以下命令，啟動 nfs 服務;創建共享目錄
mkdir -p /nfs/data# 在master執行
systemctl enable rpcbind
systemctl enable nfs-server
systemctl start rpcbind
systemctl start nfs-server# 使配置生效
exportfs -r#檢查配置是否生效
exportfs

?

1.2、配置默認存儲

• 創建nfs.yam文件

vi nfs.yaml

• 根據自己的情況，更改文件內容即可

## 創建了一個存儲類
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"  ## 刪除pv的時候，pv的內容是否要備份---
apiVersion: apps/v1
kind: Deployment

1.3、k8s應用nfs

kubectl apply -f nfs.yaml

2、安裝kubesphere

• 下面操作主節點執行即可

2.1、下載核心文件

wget https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/kubesphere-installer.yaml

wget https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/cluster-configuration.yaml

2.2、修改

• 需要指定下etcd服務IP，一般為master節點的IP
• cluster-configuration.yaml包含了kubesphere工具，默認都是false，在安裝kubesphere時不會安裝這些工具，我們可以選擇想要安裝的工具，改為true即可
• 配置低的話，不建議在安裝時去同步安裝工具

2.3、執行安裝

kubectl apply -f kubesphere-installer.yaml

kubectl apply -f cluster-configuration.yaml

?

• 注意：電腦配置一定要滿足官方的最低要求，否則安裝會不成功！

2.4、查看安裝進度

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f

• 安裝時間會有點長，建議用上面命令查看
• 安裝成功截圖如下：

• 也可以查看service的生成狀態，下面這個是成功后的service列表

kubectl get svc -A

2.5、登錄

地址：http://k8s節點的IP:30880
