# Nginxの設定

1. `/etc/nginx/conf.d/misskey.conf`もしくは`/etc/nginx/sites-available/misskey.conf`を作成し、下の設定例をコピーします。\
   （ファイル名はmisskeyでなくても構いません。）
2. 次のように編集します。
   1. example.tldを自分が用意したドメインに置き換えます。\
      `ssl_certificate`と`ssl_certificate_key`はLet's Encryptで取得した証明書のパスになるようにします。
   2. CloudflareなどのCDNを使う場合は、「If it's behind another reverse proxy or CDN, remove the following.」から4行を削除します。
3. `/etc/nginx/sites-available/misskey.conf`を作成した場合は、`/etc/nginx/sites-enabled/misskey.conf`としてシンボリックリンクを作成します。\
   `sudo ln -s /etc/nginx/sites-available/misskey.conf /etc/nginx/sites-enabled/misskey.conf`
4. `sudo nginx -t` で設定ファイルが正常に読み込まれるか確認します。
5. `sudo systemctl restart nginx` でnginxを再起動します。
