Welcome to this OpenVPN "road warrior" installer!
 
I need to ask you a few questions before starting the setup.
You can leave the default options and just press enter if you are ok with them.
 
First, provide the IPv4 address of the network interface you want OpenVPN
listening to.
IP address: 172.28.0.3
 
This server is behind NAT. What is the public IPv4 address or hostname?
Public IP address / hostname: xxx.xxx.xxx.xxx
 
Which protocol do you want for OpenVPN connections?
   1) UDP (recommended)
   2) TCP
Protocol [1-2]: 1
 
What port do you want OpenVPN listening to?
Port: 5556
 
Which DNS do you want to use with the VPN?
   1) Current system resolvers
   2) 1.1.1.1
   3) Google
   4) OpenDNS
   5) Verisign
DNS [1-5]: 1
 
Finally, tell me your name for the client certificate.
Please, use one word only, no special characters.
Client name: yangzhou
 
Okay, that was all I needed. We are ready to set up your OpenVPN server now.
Press any key to continue...

Your client configuration is available at: /root/yangzhou.ovpn
If you want to add more clients, you simply need to run this script again!

将客户端配置文件 /root/client.ovpn，下载到本地以备客户端使用

1.2. 添加账号

在openvpn目录下的userfile.sh中添加用户和密码，以空格隔开

cat /etc/openvpn/userfile.sh
username password

 开发云服务器端口 端口有tcp和udp 记得要开对应的

二. 客户端部署使用

2.1. 安装openvpn客户端

1. 客户端下载地址：https://swupdate.openvpn.org/community/releases/openvpn-install-2.4.0-I602.exe
   安装步骤略(可自定义安装路径)

2.2. 配置客户端

将安装好的客户端打开，点击Import file 把准备好的客户端配置文件导入进去。

2.3. 连接openvpn服务器

打开客户端，点击Connect，使用服务器端已添加的账号登录

END

附：

安装完毕后，再次执行脚本openvpn-install.sh 会有四个菜单选项(添加、撤销、卸载、退出)，可根据自身实际情况应用,如下：

Looks like OpenVPN is already installed.
 
What do you want to do?
   1) Add a new user
   2) Revoke an existing user
   3) Remove OpenVPN
   4) Exit
Select an option [1-4]:

这里有个不足之处是，当使用多证书时，账号是通用的。即同一个账号，可以应用于不同的证书。

如果想要不同用户使用不同的证书进行登录[无账号]，欢迎访问原项目地址：
