中断测试
两台web服务器安装nginx
web1
[root@web01 ~]# echo web1 > /usr/share/nginx/html/index.html //添加测试页
[root@web01 ~]# route add -net 10.3.0.0/20 gw 192.168.52.100 //添加路由
web2
[root@web01 ~]# echo web2 > /usr/share/nginx/html/index.html //添加测试页
[root@web01 ~]# route add -net 10.3.0.0/20 gw 192.168.52.100 //添加路由

nfs-server服务器
安装nfs-utils
[root@nfs-server ~]# yum -y install nf-utils
[root@nfs-server ~]# mkdir /webdata //创建存放网站代码目录
[root@nfs-server ~]# echo "nfs-test..." > /webdata/index.html
配置nfs服务器
[root@nfs-server ~]# vim /etc/exports
//在文件中输入以下数据
/webdata 192.168.52.0/24 (rw)
[root@nfs-server ~]# systemctl start nfs-server.service //启动nfs服务
[root@nfs-server ~]# exportfs -v //检查nfs输出是否正常
