安装pvc

安装nfs服务

yum install -y nfs-utils

创建共享目录

sudo mkdir -p /home/hogwarts/nfs
sudo chmod -R 777 /home/hogwarts/nfs

编辑配置

sudo vi /etc/exports
## 加上一下内容
/home/hogwarts/nfs *(rw,sync,no_root_squash,no_subtree_check)

让配置生效

sudo exportfs -rav

# 输出 exporting *:/home/hogwarts/nfs

启动并设置开机自启

sudo systemctl enable --now nfs-server

验证nfs服务

showmount -e localhost
# 输出 Export list for localhost:
# /home/hogwarts/nfs *

apply
