NodejsアプリでStunnel、Varnish、nginxを使用していますが、https以外のページ( http://manager.domain.com )をそれぞれのhttpsページ(- https://manager.domain.com )。すべてのトラフィックが最初にワニスを通過するため、リダイレクトループでスタックします。この設定の主な理由は、SSLでソケットを使用することです。
Stunnelはポート443でリッスンします。SSL接続を終了し、ポート80でVarnishにトラフィックを渡します。Varnishはポート80でリッスンし、必要に応じて81のNginxとポート3000のNode.jsの間で他のトラフィックを分割します。Nginxはポート81でリッスンします。静的ファイルおよびその他のNode.js以外のページ。
これがnginxconfファイルです

ポート81に2つのserver
ブロックがあり、manager.domain.com
がホストヘッダーとして構成されています-nginxはリクエストがstunnelを通過したかどうかを知る方法がないため、最初のブロックが優先され、リダイレクトが常に発生します。
リクエストがstunnelからのものかどうかに基づいてVarnishにリダイレクトを行わせるか(リクエストのclient.ip
-127.0.0.1はstunnelからのものであることを確認してください)、またはVarnishにstunnelからのリクエストにヘッダーを付けることをお勧めしますnginxがそれらの処理方法を決定できるようにします。
