官方文档：https://guide.v2fly.org/advanced/h2_tls_web.html#web-%E6%9C%8D%E5%8A%A1%E5%99%A8

编辑/usr/local/etc/v2ray/config.json文件，写入如下内容

UUID可在这里生成：https://www.uuidgenerator.net/version1

{
  "inbounds": [
    {
      "port": 44302,
      "listen":"127.0.0.1",
      "protocol": "vmess",
      "settings": {
        "clients": [
          {
            "id": "你的UUID",
            "alterId": 0
          }
        ]
      },
      "streamSettings": {
        "network": "ws",
        "wsSettings": {
        "path": "/ray"
        }
      }
    }
  ],
  "outbounds": [
    {
      "protocol": "freedom",
      "settings": {}
    }
  ]
}

service v2ray restart
# 启动v2ray

service v2ray status
# 查看状态

systemctl enable v2ray
# 允许开机自启

配置Caddy v2

创建Caddyfilev2ray文件

vim /etc/caddy/Caddyfilev2ray

写入以下内容

/usr/share/caddy是你的网站源文件目录

将example.com改成你的域名

example.com {
    root * /usr/share/caddy
    file_server
    log {
        output file /etc/caddy/caddy.log
    }
    tls {
        protocols tls1.2 tls1.3
        ciphers TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256
        curves x25519
    }
    @v2ray_websocket {
        path /ray
        header Connection *Upgrade*
        header Upgrade websocket
    }
    reverse_proxy @v2ray_websocket localhost:44302
}

caddy stop
caddy start --config /etc/caddy/Caddyfilev2ray --adapter caddyfile
# 启动caddy

设置Caddy开机自启

编辑/lib/systemd/system/rc-local.service，在文件尾部添加以下内容

[Install]
WantedBy=multi-user.target

创建/etc/rc.local文件并输入以下内容

#!/bin/sh -e
# 
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# caddy v2ray start
/usr/bin/caddy start --config /etc/caddy/Caddyfilev2ray --adapter caddyfile
/usr/bin/caddy reload --config /etc/caddy/Caddyfilev2ray

exit 0 # 如果文件末尾不存在exit 0，请添加此行

sudo chmod +x /etc/rc.local
# 添加执行权限

systemctl enable rc-local.service
# 启用rc-local服务
