# 20240205150537 Caddyをraspi4にインストール
|
||
#raspi #caddy #web_server
|
||
|
||
### インストール
|
||
|
||
[How to Setup a Raspberry Pi Caddy Web Server - Pi My Life Up](https://pimylifeup.com/raspberry-pi-caddy-web-server/) の方法が現在 20240205 は利用できない。
|
||
```
|
||
Err:4 https://dl.cloudsmith.io/public/caddy/stable/deb/debian any-version InRelease
|
||
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY ABA1F9B8875A6661
|
||
```
|
||
このgpgエラーは、鍵が公開されていないのか、解決不能。
|
||
|
||
仕方ないのでソースからビルド。
|
||
|
||
まずgoが必要。
|
||
[[20240205152229 raspi4にgoをインストールする|raspi4にgoをインストールする]]
|
||
|
||
caddyをビルド。
|
||
```sh
|
||
$ sudo apt install git (インストールしてなければ)
|
||
$ git clone --depth=1 https://github.com/caddyserver/caddy.git
|
||
$ cd caddy/cmd/caddy/
|
||
$ go build
|
||
$ cd ../../..
|
||
$ sudo mv caddy /usr/local
|
||
```
|
||
`/usr/local/caddy/cmd/caddy`
|
||
にパスを通す。 /etc/profileに追加。
|
||
|
||
```
|
||
$ sudo setcap cap_net_bind_service=+ep /usr/local/caddy/cmd/caddy/caddy
|
||
$ sudo visudo
|
||
```
|
||
|
||
`[username] ALL=(ALL:ALL) NOPASSWD: /usr/sbin/setcap` を追加。
|
||
|
||
WEBサーバーのルートを作る
|
||
```
|
||
$ sudo mkdir /var/www
|
||
$ sudo chmod a+rw /var/www
|
||
```
|
||
|
||
Caddyfileを /etc 以下に作成
|
||
```
|
||
$ sudo mkdir /etc/caddy/
|
||
$ sudo touch /etc/caddy/Caddyfile
|
||
$ sudo chmod a+rw /etc/caddy/Caddyfile
|
||
```
|
||
|
||
Caddyfileを編集
|
||
```
|
||
localhost, 127.0.0.1 192.168.1.100(自分で決めたIPアドレス), saipi4.local(自分で決めたhostname), notes.kinoshita-lab.org(cludflareで設定したhostname) {
|
||
root * /var/www
|
||
file_server
|
||
}
|
||
|
||
```
|
||
/var/wwwにindex.htmlを作成
|
||
|
||
```
|
||
<!doctype html>
|
||
<html>
|
||
<head>
|
||
<title>AYBABTU</title>
|
||
</head>
|
||
<body>
|
||
<p>All your base are belong to us.</p>
|
||
</body>
|
||
</html>
|
||
```
|
||
|
||
caddyを起動
|
||
```
|
||
caddy run --config /etc/caddy/Caddyfile
|
||
```
|
||
証明書が無いなど、色々怒られるかもだけど、とりあえずネットワーク内から接続できる。 saipi4は私のraspi4のhostname。

### サービス化
|
||
[Keep Caddy Running — Caddy Documentation](https://caddyserver.com/docs/running#linux-service)
|
||
|
||
上記を参考にしつつ、パスなどを自分の環境にあわせる。
|
||
|
||
```
|
||
$ sudo groupadd --system caddy
|
||
```
|
||
|
||
caddy.serviceはこちらを使用
|
||
[dist/init/caddy.service at master · caddyserver/dist · GitHub](https://github.com/caddyserver/dist/blob/master/init/caddy.service)
|
||
|
||
変更点は下記2カ所
|
||
```
|
||
ExecStart=/usr/local/caddy/cmd/caddy/caddy run --environ --config /etc/caddy/Caddyfile
|
||
ExecReload=/usr/local/caddy/cmd/caddy/caddy reload --config /etc/caddy/Caddyfile --force
|
||
```
|
||
|
||
あとは書いてある通りに実行
|
||
```
|
||
$ sudo systemctl daemon-reload
|
