Caddy-简单的反向代理

2026-05-29

只需要三行代码即可实现反向代理并自动申请ssl证书

example.com {
  reverse_proxy 127.0.0.1:1234
}

首先，先安装Caddy

sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install caddy

然后编辑Caddyfile并写入开头的代码，并将域名和端口换为你自己的即可

nano /etc/caddy/Caddyfile

sudo caddy reload --config /etc/caddy/Caddyfile

sudo systemctl restart caddy

最后，申请的证书位置在

/var/lib/caddy/.local/share/caddy/certificates/acme-v02.api.letsencrypt.org-directory/
