Magento Redis Sitzung Problem: nach ein paar Stunden Website verlangsamt

Question

Ich habe versucht, Redis für Magento für Leistungssteigerung zu verwenden, aber ich habe Probleme mit Redis in Magneto CE 1.9.2.4.

Meine Website nach einigen Stunden verlangsamt, wenn ich Redis verwende, manchmal kann es etwa eine Minute dauern, um eine Seite zu laden. Seltsam, dass Admin-Zone normal funktioniert.

Ich benutze easyengine Stapel, um Hauptabhängigkeiten zu Server zu installieren: hhvm als PHP-Compiler, Nginx als Webserver, Redis als Cache-Server.

Server OS: Ubuntu 14.04 CPU: 4 x 2,40 GHz RAM: 3072 MB + 384 MB plus + 1536 MB SWAP (mit 3261 MB)

Answer 1

Redis Sitzung

SCHRITT 1 Verriegelung:

hinzufügen <disable_locking> zu Ihrem Magento local.xml

<session_save><![CDATA[db]]></session_save> 
<redis_session> 
. 
. 
    <disable_locking>1</disable_locking> 
</redis_session> 

SCHRITT 2:

NB: Ältere Versionen von Cm_RedisSession diese Funktion nicht haben. Um dies herauszufinden, öffnen Sie die App/code/community/Cm/RedisSession/Model/Session.php und suchen Sie nach "disable_locking".

grep disable_locking App/Code/Gemeinschaft/Cm/RedisSession -r App/Code/Gemeinschaft/Cm/RedisSession/Model/Session.php::! (string ("{$ config-> descend ('disable_locking')}}")? (bool) "{$ config-> absteigend ('disable_locking')}}": self :: DEFAULT_DISABLE_LOCKING);

If you see the above, it will work with no further action. This updated code is bundled as of Magento CE 1.9 or EE 1.14. 
If you don’t see that, then the module needs to be updated.
