手动搭建nfs服务器

1.准备两台服务器，一台客户端，一台服务端

[root@afei ~]# hostnamectl set-hostname client
[root@afei ~]# bash
[root@client ~]# 
[root@clocalhost ~]# hostnamectl set-hostname server
[root@client ~]# bash
[root@server ~]# 

2.两台主机安装NFS

[root@client ~]# yum -y install nfs-utils
Updating Subscription Management repositories.

Repository AppStream is listed more than once in the configuration

4.开放/nfs/shared目录

[root@server ~]# mkdir /nfs
[root@server ~]# cd /nfs
[root@server nfs]# mkdir /shared
[root@server nfs]# vim /etc/exports

5.查看端口号

[root@server ~]# ss -antl

LISTEN           

6.在客户端上挂载nfs目录

[root@client ~]# mount -t nfs 192.168.240.134:/nfs /media/
