Caddy

Caddy 入门

创建 Caddyfile

localhost {
    respond "Hello, world!"
}

localhost:2016 {
    respond "Goodbye, world!"
}

localhost:2017 {
    root * /home/me/mysite
    file_server
}

localhost:2018 {
    reverse_proxy 127.0.0.1:9000
}

在当前目录运行 caddy run

后台运行

• caddy start
• caddy stop

本地文件 caddy file-server --listen :2015 --root ~/mysite

反向代理 caddy reverse-proxy --from :2016 --to 127.0.0.1:9000

HTTPS

只要有域名就可以默认 HTTPS

example.com

respond "Hello, privacy!"

caddy  file-server --domain example.com

*.example.com {
    tls {
        dns <provider_name> [<params...>]
    }

    @foo host foo.example.com
    handle @foo {
        respond "Foo!"
    }

    @bar host bar.example.com
    handle @bar {
        respond "Bar!"
    }

    # Fallback for otherwise unhandled domains
    handle {
        abort
    }
}

默认的 Caddy 不能使用其它的 providers，需要自行用 xcaddy 编译，或者在选择对应的模组下载，然后替换。
