# 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配置nfs-client
# 在两个子节点执行 把ip改为自己的主节点
showmount -e 192.168.0.71这样就是成功了 #创建文件夹
mkdir -p /nfs/data
#绑定文件夹
mount -t nfs 192.168.0.71:/nfs/data /nfs/data配置默认存储 使用vi sc.yaml 创建一个文件,然后把内容复制进去,执行kubectl apply -f sc.yaml 创建了一个存储类
