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.

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:

• https://github.com/nexcess/magento-turpentine/blob/master/app/code/community/Nexcessnet/Turpentine/etc/system.xml#L320

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.

Weitere Informationen zum Einrichten von SSL für Magento + Terpentine:

• https://github.com/nexcess/magento-turpentine/issues/596
• https://github.com/nexcess/magento-turpentine/wiki/SSL_Support
• https://www.digitalocean.com/community/tutorials/how-to-configure-varnish-cache-4-0-with-ssl-termination-on-ubuntu-14-04

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.
