基于Ubuntu-22.04安装K8s-v1.28.2实验(三)数据卷挂载NFS(网络文件系统)

安装 NFS 服务器: 首先,打开终端并安装 NFS 服务器软件包:

sudo apt update
sudo apt install nfs-kernel-server

创建共享目录: 决定哪个目录你想要共享,然后创建它(如果还不存在):

sudo mkdir -p /nfs/data

配置共享目录权限: 配置目录的权限,确保 NFS 客户端可以访问它:

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

编辑 /etc/exports 文件: 决定你想要共享的目录和哪些客户端可以访问它,然后编辑 /etc/exports 文件:

sudo nano /etc/exports
在这个文件中,添加以下行

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

应用 exports 文件并重启服务: 修改完 /etc/exports 文件后,应用更改并重启 NFS 服务:

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

节点安装数据卷驱动

每个节点都要运行 apt install nfs-common
