基於Ubuntu-22.04安裝K8s-v1.28.2實驗（三）數據卷掛載NFS（網絡文件系統）

安裝 NFS 服務器： 首先，打開終端並安裝 NFS 服務器軟件包：

sudo apt update
sudo apt install nfs-kernel-server

創建共享目錄： 決定哪個目錄你想要共享，然後創建它（如果還不存在）：

sudo mkdir -p /nfs/data

配置共享目錄權限： 配置目錄的權限，確保 NFS 客戶端可以訪問它：

sudo chown root:root /nfs/data
sudo chmod 777 /nfs/data

編輯 /etc/exports 文件： 決定你想要共享的目錄和哪些客戶端可以訪問它，然後編輯 /etc/exports 文件：

sudo nano /etc/exports
在這個文件中，添加以下行

/nfs/data *(rw,sync,no_subtree_check,no_root_squash)

應用 exports 文件並重啓服務： 修改完 /etc/exports 文件後，應用更改並重啓 NFS 服務：

sudo exportfs -ra
sudo systemctl restart nfs-kernel-server

節點安裝數據卷驅動

每個節點都要運行 apt install nfs-common
