一、新建nfs服务器（192.168.1.44）

1.基础配置（IP地址防火墙等）

2.配置时间同步

[root@localhost ~]# yum -y install ntpdate.x86_64
[root@localhost ~]# ntpdate time2.aliyun.com
27 Sep 10:28:08 ntpdate[1634]: adjust time server 203.107.6.88 offset 0.014965 sec
[root@localhost ~]# crontab -e //设置计划任务
* 3 * * * /sbin/ntpdate time2.aliyun.com

3.安装nfs服务应用

[root@localhost ~]# yum -y install rpcbind nfs-utils

4.配置文件

[root@localhost ~]# echo "/root/pes *(rw,sync)" >> /etc/exports
[root@localhost ~]# cat /etc/exports
/root/pes *(rw.sync)

5.准备pes资源目录（部署考试系统项目）

6.启动服务

[root@localhost ~]# systemctl start rpcbind.service nfs-server.service //启动
[root@localhost ~]# systemctl enable rpcbind.service nfs-server.service //设置开机启动
Created symlink from /etc/systemd/system/multi-user.target.wants/nfs-server.service to /usr/lib/systemd/system/nfs-server.service.

7.验证

[root@localhost ~]# showmount -e localhost //这样代表成功
Export list for localhost:
/root/pes *

二、部署前端

1.创建web-deployment.yaml资源清单文件

[root@k8s-master ~]# mkdir pes-k8s
[root@k8s-master ~]# cd pes-k8s
[root@k8s-master pes-k8s]# vim web-deployment.yaml

[root@k8s-master pes-k8s]# kubectl create -f web-deployment.yaml
deployment.apps/web-deployment created
[root@k8s-master pes-k8s]# kubectl get po -owide

2.访问测试

[root@k8s-master pes-k8s]# curl 172.16.169.186
