Terpentin + Lack, extrem langsam (30s +) bei Verwendung von SSL

8

Ich bin neu in Terpentin und Lack. Hier sind meine Einstellungen:

nginx -> lack -> nginx -> php5-fpm

Lack funktioniert gut, wenn ich nginx so einstelle, dass er Port 80 abhört und dann ohne Verwendung von ssl zum Lack weiterleitet (ohne direkt Lack auf 80 auszuführen). Es funktioniert gut, zwischengespeicherte Seite ist schnell, der erste Treffer ist etwas langsamer (erster Treffer ca. 200 ms, zwischengespeichert Seitentreffer ca. 7-20 ms).

Dann versuche ich, den Lack mit https zu verpacken. Zuerst habe ich ihn mit einem selbstsignierten Zertifikat getestet. Der erste Treffer wurde höllisch langsam ( 30s + , ja, Sekunden, nicht ms). Der zwischengespeicherte Treffer ist immer noch schnell, 7-20ms. Dann bekomme ich ein Zertifikat von letsencrypt.org, das das Problem jedoch nicht behoben hat.

Ich verstehe nicht ganz, was hier vor sich geht, und habe keine Ahnung, wie ich herausfinden kann, warum es so langsam ist.

Bearbeiten: Während der Wartezeit von 30 Jahren ist keine signifikante Erhöhung der RAM- oder CPU-Auslastung zu verzeichnen.

Ich habe versucht, Pfund zu verwenden, um Lack zu wickeln, das gleiche Problem. nginx version: nginx / 1.4.6 (Ubuntu) varnishd (lack-4.0.3 revision b8c4a34).
Kaninchen.aaron
Nginx 1.4.6 ??? Auch mit Ihrem Magento stimmt etwas nicht. Haben Sie versucht, https direkt bei nginx anzurufen?
MagenX
@MagenX Ich habe den Lack entfernt, Nginx bedient PHP5-Fpm direkt mit SSL, es gibt kein Problem. Ca. 200 ms pro Seitenladung.
Kaninchen.aaron
Könnte damit zusammenhängen, wie Sie SSL auslagern - können Sie dasselbe ausführen, ohne SSL auszulagern?
Robbie Averill
Scheint jetzt kein Lackproblem zu sein, ich habe die Lackzeit auf 3 Sekunden eingestellt, jetzt heißt es Timeout. Daher ist es eine Auszeit von Magento.

Antworten:

Die Ursache ist höchstwahrscheinlich SSL Termination oder TLS Termination Proxy .

Ich sehe, dass Sie das SSL in Nginx selbst einstellen, die Verwendung von Pfund in Betracht ziehen oder wenn Sie einen Load Balancer verwenden, um das SSL dort anstelle von Nginx zu beenden.

Wenn Sie eine genaue Verzögerung von 30 Sekunden erhalten, tritt höchstwahrscheinlich eine Zeitüberschreitung auf:

Nachdem Sie die IP-Adressen des Site-Crawlers deaktiviert haben, konnte die lokale Rückschleife für die SSL-Cookies ordnungsgemäß eingestellt werden und nicht versucht werden, das Frontend zu erreichen.

Ihre Konfiguration sollte besser anders sein:
Lack vorne an Port 80, dann Nginx an Port 443 und 8000:

        varnish:80 -> nignx:8000 -> php-fpm:9000 
user ->|         |
        nginx:443

Wenn Sie HTTPS auch für Varnish verwenden, fügen Sie diese Header besser hinzu: 

proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Forwarded-Port 443;

dann auf nginx: 8000 empfangsteil musst du echte ip hinzufügen:

set_real_ip_from   127.0.0.1;
real_ip_header     X-Forwarded-For;

sonst wird es ein Chaos sein. Auf diese Weise fängt Varnish: 80 immer direkte Benutzeranforderungen ab, und nginx: 443 entschlüsselt ssl an Varnish, und Varnish sendet dann eine nicht zwischengespeicherte Anforderung an nginx: 8000

Diese Konfiguration ist etwas sauberer, aber es ist wirklich schwer zu sagen, warum Sie 30 + Sek. haben.

Nun, der gesamte Datenverkehr läuft über SSL, sodass Port 80 nicht öffentlich zugänglich sein muss. Ich werde versuchen, morgen Header hinzuzufügen
rabbit.aaron
Offensichtlich haben Sie in Ihrer Konfiguration keine Weiterleitung zum 443-Server, und
Nginx
Der erste serverBlock dient nur zu Testzwecken. Der zweite serverBlock ist auf 443 zu hören. Und das
