由于Shadowsocks在国内被大范围识别封锁，所以转向V2Ray。虽然V2Ray作为一个平台，比起Shadowsocks复杂许多，但是安装部署其实已经集成的非常好。以下是部署步骤：

1、安装V2Ray服务端

bash <(curl -L -s https://install.direct/go.sh)

执行完后得到以下内容

以上信息中，有两项需要记下：UUID和PORT

启动V2Ray服务

systemctl start v2ray
systemctl enable v2ray

由于需要端口通讯，建议将端口加入防火墙白名单。这里只是示范，所以关闭防火墙

iptables -F
systemctl stop firewalld

2、安装Windows客户端

Windows系统客户端可以使用V2RayN，首先去Github上下载最新的release：

• 【V2RayN-Core 发布地址】：下载页面列表中v2rayN-Core.zip这个文件

将压缩包解压，执行v2rayN.exe即可启动客户端。

启动之后，选择服务器->添加[VMess]服务器，按之前在服务器上得到的UUID和PORT填写
