檢視 Caddy 的原始碼

'''Caddy'''是一個[[HTTP]]伺服器，主打自動化[[HTTPS]]以及簡易的設定。

== 安裝 ==

在[[Debian]]與[[Ubuntu]]上都可以使用官方的APT repository安裝：

<syntaxhighlight lang="bash">
curl -Lfs https://dl.cloudsmith.io/public/caddy/stable/gpg.key | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg; echo -e "deb [signed-by=/usr/share/keyrings/caddy-stable-archive-keyring.gpg] https://dl.cloudsmith.io/public/caddy/stable/deb/debian any-version main\ndeb-src [signed-by=/usr/share/keyrings/caddy-stable-archive-keyring.gpg] https://dl.cloudsmith.io/public/caddy/stable/deb/debian any-version main" | sudo tee /etc/apt/sources.list.d/caddy-stable.list; sudo apt update; sudo apt install -y caddy; sudo apt clean
</syntaxhighlight>

另外下面的範例會用到transform，可以透過這個指令安裝：

<syntaxhighlight lang="bash">
sudo caddy add-package github.com/caddyserver/transform-encoder
</syntaxhighlight>

=== xcaddy ===

xcaddy是官方維護的module管理套件，有蠻多module會需要透過xcaddy安裝，通常需要搭配Golang一起裝：

<syntaxhighlight lang="bash">
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/xcaddy/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-xcaddy-archive-keyring.gpg; curl -1sLf 'https://dl.cloudsmith.io/public/caddy/xcaddy/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-xcaddy.list; sudo apt update; sudo apt install -y golang xcaddy; sudo apt clean
</syntaxhighlight>

== 設定 ==

重複使用設定的方法：

<syntaxhighlight lang="nginx">
(subdomain-log) {
        log {
                format transform `{request>remote_ip} - {request>user_id} [{ts}] "{request>method} {request>uri} {request>proto}" {status} {size} "{request>headers>Referer>[0]}" "{request>headers>User-Agent>[0]}"` {
                        time_format "02/Jan/2006:15:04:05 +0000"
                }
                output file /var/log/caddy/{args[0]}_access.log {
                        mode 0640
                }
        }
}

bar.example.com {
        # ...
        import subdomain-log bar.example.com
        # ...
}

foo.example.com {
        # ...
        import subdomain-log foo.example.com
        # ...
}
</syntaxhighlight>
