Question

我一直在尝试使用Redis for Magento来提升性能，但我在Magneto CE 1.9.2.4中遇到Redis问题。

当我使用Redis时，我的网站在几个小时后变慢，有时可能需要大约一分钟才能加载页面。奇怪的是管理区域正常工作。

我正在使用easyengine堆栈将主要依赖项安装到服务器：hhvm作为php编译器，nginx作为web服务器，redis作为缓存服务器。

服务器操作系统：Ubuntu 14.04 CPU：4 x 2.40 GHz RAM：3072 MB + 384 MB加+ 1536 MB SWAP（使用3261 MB）

我的local.xml配置：

Redis会话锁定

第1步：

将<disable_locking>添加到您的Magento local.xml

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

第2步：

注意：旧版本的Cm_RedisSession没有此功能。要找到答案，请打开app / code / community / Cm / RedisSession / Model / Session.php并查找“disable_locking”。

grep disable_locking app / code / community / Cm / RedisSession -r app / code / community / Cm / RedisSession / Model / Session.php ::！（strlen（“{$ config-＆gt; descend（'disable_locking'）}”）？（bool）“{$ config-＆gt; descend（'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.
