教程：
1. freenom 免費域名+地址解析
ytvideo2.tk
2. 安裝web伺服器+域名證書
2.1 安裝Caddy
2.1.1 安裝curl
Debian 或Ubuntu用戶
sudo apt update
sudo apt upgrade
sudo apt install curl
CentOS用戶
sudo yum update
sudo yum install curl
檢查curl安裝位置：
which curl
2.1.2 安裝caddy（https://www.cloudbooklet.com/install-caddy-with-php-https-using-letsencrypt-on-ubuntu/）
curl https://getcaddy.com | sudo bash -s personal tls.dns.cloudflare
檢查
which caddy
sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep /usr/local/bin/caddy
2.1.3 配置caddy
sudo mkdir /etc/caddy
sudo mkdir /etc/ssl/caddy
sudo mkdir /var/log/caddy
sudo chown -R root:root /etc/caddy
sudo chown -R root:www-data /etc/ssl/caddy
sudo chown -R root:www-data /var/log/caddy
sudo chmod 0770 /etc/ssl/caddy
wget https://raw.githubusercontent.com/caddyserver/caddy/master/dist/init/linux-systemd/caddy.service
sudo cp caddy.service /etc/systemd/system/
sudo chown root:root /etc/systemd/system/caddy.service
sudo chmod 644 /etc/systemd/system/caddy.service
sudo systemctl daemon-reload
sudo mkdir /var/www
sudo chown www-data:www-data /var/www
sudo nano /var/www/index.html
sudo nano /etc/caddy/Caddyfile
sudo service caddy start
sudo service caddy restart
sudo service caddy status
2.2 更改v2ray伺服器配置
sudo nano /etc/v2ray/config.json
sudo service v2ray restart
說明：
1. 在文件/etc/v2ray/config.json中添加（參考文獻1）：
“streamSettings”: {
“network”: “ws”,
“wsSettings”: {
“path”: “/ray”
}
}
即變成如下形式的內容：
{
“inbounds”: [
{
“port”: 10000,
“listen”:”127.0.0.1″,
“protocol”: “vmess”,
“settings”: {
“clients”: [
{
“id”: “b831381d-6324-4d53-ad4f-8cda48b30811”,
“alterId”: 64
}
]
},
“streamSettings”: {
“network”: “ws”,
“wsSettings”: {
“path”: “/ray”
}
}
}
],
“outbounds”: [
{
“protocol”: “freedom”,
“settings”: {}
}
]
}
2 文件Caddyfile參考內容：
ytvideo2.tk {
root /var/www/
tls [email protected]
gzip
protocols tls1.2 tls1.3
ciphers ECDHE-ECDSA-AES128-GCM-SHA256 ECDHE-RSA-AES128-GCM-SHA256 ECDHE-ECDSA-AES256-GCM-SHA384 ECDHE-RSA-AES256-GCM-SHA384 ECDHE-ECDSA-WITH-CHACHA20-POLY1305 ECDHE-RSA-WITH-CHACHA20-POLY1305
proxy /ray localhost:10000 {
websocket
header_upstream -Origin
}
}
註： Caddyfile的埠和/etc/v2ray/config.json的埠要一致，比如都是10000。
