脚本安装地址：
https://github.com/angristan/wireguard-install
curl -O https://raw.githubusercontent.com/angristan/wireguard-install/master/wireguard-install.sh
chmod +x wireguard-install.sh
./wireguard-install.sh
运行之后：
IPv4 or IPv6 public address:（这里填写服务器的外网ip地址）
Public interface: （eth0）绑定的网卡
WireGuard interface name: wg0（wg虚拟网卡，不用改）
Server WireGuard IPv4: 10.66.66.1（wg组网的ip4，不用改）
Server WireGuard IPv6: fd42:42:42::1（wg组网的ip6，不用改）
Server WireGuard port [1-65535]: 62313（wg使用端口，可改了，然后在服务器防火墙添加进去放行这个端口，注意添加UDP协议）
First DNS resolver to use for the clients: 1.1.1.1（DNS，或改成8.8.8.8）
Second DNS resolver to use for the clients (optional): 1.0.0.1（备用DNS）
WireGuard uses a parameter called AllowedIPs to determine what is routed over the VPN.
Allowed IPs list for generated clients (leave default to route everything): 0.0.0.0/0,::/0 （允许客户端ip，不用改）
Okay, that was all I needed. We are ready to setup your WireGuard server now.
You will be able to generate a client at the end of the installation.
Press any key to continue…
开始，随便取个名称：
The client name must consist of alphanumeric character(s). It may also include underscores or dashes and can’t exceed 15 chars.
Client name: jb
Client WireGuard IPv4: 10.66.66.2
Client WireGuard IPv6: fd42:42:42::2
然后会生成一个配置文件和二维码：
Here is your client config file as a QR Code:
。。。。。。。。。。。。。。。。。。。。。
。。。。。。。。。。。。。。。。。。。。。
。。。。。。。。。。。。。。。。。。。。。
Your client config file is in /root/wg0-client-jb.conf
If you want to add more clients, you simply need to run this script another time!
WireGuard is running.
You can check the status of WireGuard with: systemctl status wg-quick@wg0
If you don’t have internet connectivity from your client, try to reboot the server.
在客户端下载个工具软件导入刚才的conf文件，或者扫码就行：
