安裝 open-iscsi
kubectl apply -f https://raw.githubusercontent.com/longhorn/longhorn/v1.1.2/deploy/prerequisite/longhorn-iscsi-installation.yaml
部署完成後，運行以下命令來檢查安裝程序的 pod 狀態：
kubectl get pod | grep longhorn-iscsi-installation
也可以通過以下命令查看日誌，查看安裝結果：
kubectl logs longhorn-iscsi-installation-pzb7r -c iscsi-installation
安裝 NFSv4 客戶端
apt-get install nfs-common
yum install nfs-utils
nfs安裝程序
kubectl apply -f https://raw.githubusercontent.com/longhorn/longhorn/v1.1.2/deploy/prerequisite/longhorn-nfs-installation.yaml
部署完成後，運行以下命令來檢查安裝程序的 pod 狀態：
kubectl get pod | grep longhorn-nfs-installation
NAME READY STATUS RESTARTS AGE
longhorn-nfs-installation-t2v9v 1/1 Running 0 143m
longhorn-nfs-installation-7nphm 1/1 Running 0 143m
安裝 Longhorn
kubectl apply -f https://raw.githubusercontent.com/longhorn/longhorn/v1.1.2/deploy/longhorn.yaml
監視安裝進度的一種方法是觀察在longhorn-system命名空間中創建的 pod ：
kubectl get pods \ --namespace longhorn-system \ --watch
後台介面可以從rancher ui進入
使用以下命令創建一個名為的 StorageClass longhorn：
kubectl create -f https://raw.githubusercontent.com/longhorn/longhorn/v1.1.2/examples/storageclass.yaml
