magento memcached未缓存文件

问题：
当我从

magento admin

刷新所有缓存时，没有使用memcached缓存文件。 我已经在magento上安装了memcached 它的统计数据如下所示，配置在local.xml文件上完成，如下所述。 请有人帮忙使它工作。 我怀疑

configuration

或

memcached

上可能存在错误

首先，确保检查Memcache守护进程是否正在实际运行

ps ax | grep memcache

然后，确保您实际安装了PHP扩展

在文档中搜索Memcache以确保它已实际加载

这是Memcache无法工作的两个唯一原因

验证Memcache是否正在使用非常简单

禁用Magento管理（系统>缓存管理）中的所有缓存

单击“刷新缓存存储”

启用所有缓存

然后清空

./var/cache/*

目录，然后在前端重新加载一个页面，并观察上面目录的内容。如果它仍然为空，则表示正在使用Memcache

---

请参见

根据您使用的Magento版本，用于缓存的local.xml选项将有所更改。在never版本中，您应该同时定义后端和slow_后端，并将Memcache配置为后端

以下几点可能会有所帮助：

<cache>
<slow_backend></slow_backend> 
<fast_backend>memcached</fast_backend>
<fast_backend_options>
  <servers>
    <server>
      <host>127.0.0.1</host>
      <port>11211</port>
      <persistent>1</persistent>
    </server>
  </servers>
</fast_backend_options>

<backend>memcached</backend>
<memcached>
  <servers>
    <server>
      <host>127.0.0.1</host>
      <port>11211</port>
      <persistent>1</persistent>
    </server>
  </servers>
</memcached>
</cache>

memcached
127.0.0.1
11211

memcached
127.0.0.1

参考以下设置：

    <config>
    <global>
        <session_save><![CDATA[]]></session_save> <!-- db / memcache / empty=files -->
        <session_save_path><![CDATA[]]></session_save_path><!-- e.g. for memcache session save handler tcp://10.0.0.1:11211?persistent=1&weight=2&timeout=10&retry_interval=10 -->
        <session_cache_limiter><![CDATA[]]></session_cache_limiter><!-- see http://php.net/manual/en/function.session-cache-limiter.php#82174 for possible values -->
        <cache>
            <backend></backend><!-- apc / memcached / xcache / empty=file -->
            <slow_backend></slow_backend> <!-- database / file (default) - used for 2 levels cache setup, necessary for all shared memory storages -->
            <memcached><!-- memcached cache backend related config -->
                <servers><!-- any number of server nodes can be included -->
                    <server>
                        <host><![CDATA[]]></host>

前几天我遇到了这个问题。如果我没记错的话，那是因为没有将文件名前缀留空（或

）

$ aptitude install php5-memcache
$ aptitude install memcached

extension=memcache.so

[memcache]  
memcache.dbpath="/var/lib/memcache"  
memcache.maxreclevel=0  
memcache.maxfiles=0  
memcache.archivememlim=0  
memcache.maxfilesize=0  
memcache.maxratio=0  

;Use memcache as a session handler  
session.save_handler=memcache  

;Defines server urls to use for session storage  
session.save_path="tcp://localhost:11211?persistent=1&weight=2&timeout=10&retry_interval=10"
