1、开放/nfs/shared目录，供所有用户查询资料；
服务端：
安装NFS包
[root@localhost ~]# yum install rpcbind
[root@localhost ~]# yum install nfs-utils
关闭防火墙和selinux
[root@localhost nfs]# systemctl stop firewalld
[root@localhost nfs]# setenforce 0
启动NFS服务
[root@localhost ~]# systemctl start nfs-server
[root@localhost ~]# systemctl start rpcbind
编辑配置文件
[root@localhost ~]# vim /etc/exports
[root@localhost ~]# cat /etc/exports
/nfs/shared 192.168.189.0/24(ro)
创建共享目录
[root@localhost ~]# mkdir /nfs/shared -p
重启NFS服务
[root@localhost yum.repos.d]# systemctl restart nfs-server rpcbind
客户端：
安装NFS包
[root@client ~]# yum install rpcbind
[root@client ~]# yum install nfs-utils
关闭防火墙和selinux
[root@client ~]# systemctl stop firewalld
[root@client ~]# setenforce 0
在客户端查看共享目录
[root@localhost ~]# showmount -e 192.168.189.130
Export list for 192.168.189.130:
/nfs/shared 192.168.189.0/24
创建挂载点目录，挂载
[root@clinet ~]# mkdir /haha
[root@localhost haha]# mount 192.168.189.130:/nfs/shared /haha
查看挂载是否成功
[root@localhost haha]# df -h

2、开放/nfs/upload目录，供所有用户上传下载资料；
服务端：
创建共享目录
[root@localhost ~]# mkdir /nfs/upload
修改配置文件
[root@localhost ~]# vim /etc/exports
[root@localhost ~]# cat /etc/exports
/nfs/upload 192.168.189.0/24(rw)
重启NFS服务
[root@localhost ~]# systemctl restart nfs-server
[root@localhost ~]# systemctl restart rpcbind
客户端：
在客户端查看共享目录
[root@client ~]# showmount -e 192.168.189.130
Export list for 192.168.189.130:
/nfs/upload 192.168.189.0/24
创建挂载点目录
[root@client haha]# mkdir /xixi
[root@client haha]# mount 192.168.189.130:/nfs/upload /xixi
查看是否挂载成功
[root@client ~]# df -hT
df: /haha: Stale file handle
