OpCache pro PHP-FPM Pool/Domain

Question

Hallo,

ich würde gerne den OpCache Speicherplatz pro Pool/Domain nutzen. Aktuell wird der Speicherplatz jedoch pro PHP Konfiguration geteilt, d.h. alle Scripts der Domains welche dieselbe PHP Konfiguration verwenden werden mir im OpCache angezeigt. Laut meiner Recherche sollte der OpCache Speicherplatz nur vom jeweiligen PHP-FPM Pool genutzt werden. Da pro Domain ein PHP-FPM Pool angelegt wird, sollte dies doch nicht für alle geteilt werden?

 

# Scripts welche im selben OpCache Speicherplatz gecached werden

/var/customers/webs/customer01/domain-1.com/test-1.php
/var/customers/webs/customer01/domain-2.com/test-2.php
/var/customers/webs/customer01/domain-3.com/test-3.php
/var/customers/webs/customer02/domain-4.com/test-4.php
/var/customers/webs/customer02/domain-5.com/test-5.php

Sollte durch opcache.restrict_api und opcache.use_cwd=1 (default) eigentlich kein problem sein. Du könntest noch opcache.validate_permission auf 1 setzen (Validates the cached file permissions against the current user.) PHP default ist hier wohl 0 (aus). Du musst allerdings hierfür opcache.validate_permission noch in die PHP-FPM Versions Konfiguration eintragen als "erlaubter" php.ini eintrag, das müsste ein php_flag/php_admin_flag sein

Hallo d00p,

danke für deine schnelle Antwort. Leider hat das nicht funktioniert. In der domain-1.conf werden die Werte zwar geschrieben, über die OPcache Info auch angezeigt, trotzdem werden mir alle Scripts derselben PHP-FPM Version angezeigt. Das Blöde ist eben, dass ich mir bezüglich des Speicherverbrauchs nicht sicher sein kann, da ich dort solche Werte erhalte:

Das mache ich bereits. Ich habe zum Testen bei jeder Domain eine opcache.php (https://github.com/rlerdorf/opcache-status) hinterlegt. Das Script wird somit für domain-1.com bis domain-3.com mit dem User customer01 und für domain-3.com und domain-4.com mit dem User customer02 ausgeführt. Trotzdem werden alle Scripts aller PHP-FPM Pools, welche dieselbe PHP-FPM Version verwenden, in einen Topf geschmissen. Ist das Verhalten bei PHP-FPM normal? Ich habe einen anderen Server der dieselbe php.ini hat jedoch PHP-FGCI statt PHP-FPM verwendet. Dort wird korrekt pro Domain der OPcache zur Verfügung gestellt und nicht pro PHP Version.

Werden die Cache Dateien nur im RAM abgelegt oder kann ich irgendwelche Berechtigungen im Filesystem prüfen?
