Caddy及插件配置自动https

安装

参考官方文档：https://caddyserver.com/docs/install

配置

配置文件路径/etc/caddy/Caddyfile

基础配置

记得把网站目录的权限赋给caddy用户

# The Caddyfile is an easy way to configure your Caddy web server.
#
# Unless the file starts with a global options block, the first
# uncommented line is always the address of your site.
#
# To use your own domain name (with automatic HTTPS), first make
# sure your domain's A/AAAA DNS records are properly pointed to
# this machine's public IP, then replace ":80" below with your
# domain name.

:2333 {
	# Set this path to your site's directory.
	root /ulucky/www

	# Enable the static file server.
	file_server

	# Another common task is to set up a reverse proxy:
	# reverse_proxy localhost:8080

	# Or serve a PHP site through php-fpm:
	# php_fastcgi localhost:9000
}

# Refer to the Caddy docs for more information:
# https://caddyserver.com/docs/caddyfile

反向代理

:2333 {
	 reverse_proxy localhost:8000
}

配置go环境和安装xcaddy（如果已经有了可以跳过）

首先确认一下服务器的架构 uname -m

Go 官网：https://go.dev/dl/ 下载对应的版本

解压go的二进制文件

tar -C /usr/local/ -xzf go1.24.0.linux-amd64.tar.gz 

编辑shell文件

vim ~/.bashrc

添加环境变量

export PATH=$PATH:/usr/local/go/bin

激活配置文件

source ~/.bashrc

验证

go version

安装xcaddy

github地址：https://github.com/caddyserver/xcaddy

go install github.com/caddyserver/xcaddy/cmd/xcaddy@latest

配置环境变量，跟上面Go环境配置一样，增加一行就行

export PATH=$PATH:/root/go/bin
source /root/.bashrc

验证 xcaddy version

以腾讯云为例配置插件

github地址：https://github.com/caddy-dns/tencentcloud

安装插件

xcaddy build --with github.com/caddy-dns/tencentcloud

将新构建的 Caddy 二进制文件替换系统中的 Caddy

# 备份原有的 Caddy
sudo mv /usr/bin/caddy /usr/bin/caddy.backup

# 将新构建的 Caddy 复制到系统目录
sudo cp ./caddy /usr/bin/caddy

全局配置

{
  acme_dns tencentcloud {
    secret_id ""
    secret_key ""
  }
}

单独某一个站点配置

tls {
  dns tencentcloud {
    secret_id "你的ID"
    secret_key "你的key"
  }
}

记住这里还可以用环境变量，就是把ID和Key配置到环境变量中，然后env.TENCENTCLOUD_SECRET_ID这么用，哦还得带上一个括号{}
