目标：在172.16.20.19上配置nfs服务，共享/data2目录，将其挂载至172.16.20.11和172.16.20.12的/data2

一、服务端

1.装置nfs-utils、rpcbind
yum install -y nfs-utils rpcbindsystemctl enable nfs-serversystemctl enable rpcbindsystemctl start nfs-serversystemctl start rpcbind
2.配置目录
echo "/data2 172.16.20.*(rw,sync,no_root_squash)" >> /etc/exportsexportfs -r    #重载失效howmount -e    #查看确认

二、客户端

172.16.20.11和172.16.20.12别离执行以下操作

1.装置nfs-utils
yum install -y nfs-utils
2.挂载
showmount -e 172.16.20.19   #确认通信mkdir /data2    #创立挂载目录mount -t nfs 172.16.20.19:/data2 /data2
3. 增加开机挂载
echo "172.16.20.19:/data2 /data2 nfs defaults 0 0" >>/etc/fstab
