服务器未开放80和443端口情况下使用caddy开启https访问
前提：服务器需要能访问外网，且有个能解析的域名，并且在阿里云RAM用户获取AccessKey 和 accesskeysecret
下载源码xcaddy
解压并编译带dns插件的caddy包，我这里服务器是Ubuntu的，但是电脑是windows11的，所以需要交叉编译下
安装golang，网上很多，下载下来直接安装就可以
查看版本，确认安装
PS D:\code\xcaddy\cmd> go version
go version go1.25.6 windows/amd64
使用国内go代理
setx GOPROXY https://goproxy.cn,direct
再打开命令行，安装xcaddy
go clean -modcache
go install github.com/caddyserver/xcaddy/cmd/xcaddy@latest
直接打包windows版本
xcaddy build --with github.com/caddy-dns/alidns日志，第一次编译有点慢

编写配置文件 Caddyfile，tls里面配置的阿里云申请的密钥
v4.forstyle.cc:8091 {
tls {
dns alidns {
access_key_id "your access_key_id"

前台启动服务
./caddy run --config Caddyfile
后台启动
nohup ./caddy run --config Caddyfile &
