2，配置nfs服务端
[root@localhost ~]# mkdir /nfs //创建共享目录
[root@localhost nfs]# vim /etc/exports /nfs 192.168..* (rw,sync,root_squash) //分别是共享目录、允许访问的客户端、权限（读写、同步内存和硬盘数据、映射root用户为匿名用户）
3，启动nfs服务端
[root@localhost nfs]# systemctl is-enabled nfs-server //查看"nfs-server"是否开机启动
disabled
[root@localhost nfs]# systemctl enable nfs-server //将"nfs-server"加入开机启动
ln -s '/usr/lib/systemd/system/nfs-server.service' '/etc/systemd/system/nfs.target.wants/nfs-server.service'
[root@localhost nfs]# systemctl is-enabled rpcbind //查看"rpcbind"是否加入开机启动，"nfs-server"依赖于"rpcbind"
enabled
[root@localhost nfs]# systemctl restart rpcbind
[root@localhost ~]# showmount -e //查看是否共享成功
Export list for localhost.localdomain:
/nfs (everyone)
二，通过客户端验证
1，安装nfs-utils
[root@localhost ~]# yum -y install nfs-utils

2，启动"rpcbind"和"nfs-server"，并加入开机启动
3，挂载服务端的nfs共享目录"/nfs"到客户端"/mnt/nfs"下
[root@localhost ~]# showmount -e 192.168.1.10 //查看可用共享文件
Export list for 192.168.1.10:
/nfs (everyone)
[root@localhost ~]# mkdir /mnt/nfs
[root@localhost ~]# mount -t nfs 192.168.1.10:/nfs /mnt/nfs
[root@localhost ~]# ls /mnt/nfs/ [root@localhost ~]# cat /mnt/nfs/
hello
或者将挂载信息写入"/etc/fstab"中，开机自动挂载
[root@localhost ~]# vim /etc/fstab #
# /etc/fstab
# Created by anaconda on Sat Feb ::
#
