nginx proxy_pass で複数のアプリを提供する

基本的な nginx リバース プロキシを使用して、それぞれが docker コンテナー内で実行されている 3 つの異なるアプリにアクセスしようとしています。 nginx リバース プロキシが提供されておりhttp://127.0.0.1:8080、次の動作を実現したいと考えています。

  • http://127.0.0.1:8080/apiDjango バックエンド API へのルートhttp://127.0.0.1:8000/api
  • http://127.0.0.1:8080/実行中のメインReactアプリへのルートhttp://127.0.0.1:5200
  • http://127.0.0.1:8080/app22番目のアプリへのルートhttp://127.0.0.1:5300

これはnginx.conf

events {}
http { 
    server {
        listen 8080;
        server_name 127.0.0.1;
        rewrite_log on;
        error_log  /var/log/nginx/error.log notice;
        # debug with cache off
        add_header Cache-Control no-cache;


        location / {
            proxy_pass http://127.0.0.1:5200;
            proxy_set_header  Host 127.0.0.1:5200;
        }
        location /api {
            proxy_pass http://127.0.0.1:8000;
            proxy_set_header  Host 127.0.0.1:8000;
        }
        location = /app2 {
            return 302 /app2/;
        }
        location /app2/ {
            proxy_pass http://127.0.0.1:5300/;
            proxy_set_header  Host 127.0.0.1:5300;
        }
        if ($http_referer ~ https?://[^/]+/app2/(.*))
        {
            # rewrite request URI only if it isn't already started with '/app2' prefix
            rewrite ^((?!/app2).*) /app2$1;
        }
              
    }
}

2番目のアプリでこれらのルートを使用すると、http://127.0.0.1:8080/app2ページが読み込まれず、nginxリバースプロキシから以下のログが取得されます。

        <BrowserRouter>
            <Routes>
                <Route path="/" element={<Comp />} />
                <Route path="/test" element={<Comp2 />} />
            </Routes>             
        </BrowserRouter>

テスト用に2番目のアプリにキャッチオールルートを追加しました

        <BrowserRouter>
            <Routes>
                <Route path="/" element={<Comp2 />} />
                <Route path="/aaa" element={<Comp2 />} />
                <Route path="/bbb" element={<Comp />} />
                <Route path="*" element={<Comp />} />
            </Routes>             
        </BrowserRouter>

今回は、ページは読み込まれますが、app2 のすべてのパスが表示されComp、キャッチオールルールが優先されます。これは、リバースプロキシ経由でアクセスしようとしたときに発生しますhttp://127.0.0.1:8080/app2が、2 番目のアプリにそのサーバー上で直接アクセスするとhttp://127.0.0.1:5300、パスによって正しいコンポーネントが読み込まれます。

http://127.0.0.1:8080/app2 これは、 1/ nginxリバースプロキシにアクセスしたときの、1/ リバースプロキシと2/ app2 nginxサーバーからのログです。

nginxのrewrite（多くのdiff正規表現を使用）も試しましたが、同様のエラーが発生しました

        location /app2/ {
            proxy_pass http://127.0.0.1:5300/;
            proxy_set_header  Host 127.0.0.1:5300; 
            rewrite ^/app2/(.*)$ /$1 break;
        }

/app2パスから削除し、ターゲット アプリから適切なページを返すように nginx リバース プロキシを構成する方法。

答え1

あなたが解決しようとしていることが分かったと思います。

からページをリクエストすると、/app2/のような追加リソースを読み込もうとしますが/main.js、 ではなく である必要があるため、404 エラーが発生します/app2/main.js。

これが問題である場合、それを解決するために非常に複雑で不必要なアプローチを試みていることになります。

さらに、2番目のアプリも最初のアプリと同様にReactアプリであると仮定します。この場合、必要なのはアプリのベースURLを正しく設定する。

package.jsonファイル内のhomepageエントリを、サブドメイン/ネストされたディレクトリを除いた相対パスに変更します。

あなたの場合は次のようになります:

{
  ...,
  "homepage": "/app2/",
  ...
}

その場合、nginx 設定で必要なのは次のものだけです。

        location /app2/ {
            proxy_pass http://127.0.0.1:5300/;
            ### I don't think the Host header is even necessary
            # proxy_set_header  Host 127.0.0.1:5300;
        }

これで、React アプリはリバース プロキシの正しい URL を自動的に生成するはずです。
