首先，Magento 1和2中的Redis缓存配置有几个先决条件：
- Redis服务
- PHP Redis扩展
注意：建议使用最新版本。
步骤1：更新并安装Redis-server
wget http://download.redis.io/releases/redis-stable.tar.gz tar xzf redis-stable.tar.gz cd redis-stable make make test sudo make install cd utils sudo ./install_server.sh sudo service redis_6379 start sudo update-rc.d redis_6379 defaults
第2步：在Magento中配置Redis
A.配置Magento 2以将Redis用作缓存存储
将以下代码添加到您的应用程序app/etc/env.php：
<?php
// app/etc/env.php
return [
// Other directives
'cache' => [
'frontend' => [
'default' => [
'backend' => 'Cm_Cache_Backend_Redis',
'backend_options' => [
'server' => '127.0.0.1',
'database' => '0',
'port' => '6379',
'password' => ''
]
],
'page_cache' => [
'backend' => 'Cm_Cache_Backend_Redis',
'backend_options' => [
'server' => '127.0.0.1',
'database' => '1',
'port' => '6379',
'compress_data' => '0',
'password' => ''
]
]
]
]
];
B.配置Magento 2以将Redis用作会话存储
首先，您需要找到以下代码段：
'session' => [
'save' => 'files'
],
And replace it with snippet as follows:
'session' => [
'save' => 'redis',
'redis' => [
'host' => '127.0.0.1',
'port' => '6379',
'password' => '',
'timeout' => '2.5',
'persistent_identifier' => '',
'database' => '2',
'compression_threshold' => '2048',
'compression_library' => 'gzip',
'log_level' => '3',
'max_concurrency' => '6',
'break_after_frontend' => '5',
'break_after_adminhtml' => '30',
'first_lifetime' => '600',
'bot_first_lifetime' => '60',
'bot_lifetime' => '7200',
'disable_locking' => '0',
'min_lifetime' => '60',
'max_lifetime' => '2592000'
] ],
其次，通过运行以下命令清除所有缓存会话：
bin/magento c:f
C.配置Magento 1使用Redis
首先，转到您的app/etc/local.xml，然后改变：
<?xml version="1.0"?>
<config>
<global>
<install>
<date><![CDATA[Tue, 04 Oct 2016 09:53:37 +0000]]></date>
</install>
<crypt>
<key><![CDATA[e972f3c4e8436052de805bdf1f40de0f]]></key>
</crypt>
<disable_local_modules>false</disable_local_modules>
<resources>
<db>
<table_prefix><![CDATA[]]></table_prefix>
</db>
<default_setup>
<connection>
<host><![CDATA[localhost]]></host>
<username><![CDATA[magento]]></username>
<password><![CDATA[magento]]></password>
<dbname><![CDATA[magento]]></dbname>
<initStatements><![CDATA[SET NAMES utf8]]></initStatements>
<model><![CDATA[mysql4]]></model>
<type><![CDATA[pdo_mysql]]></type>
<pdoType><![CDATA[]]></pdoType>
<active>1</active>
</connection>
</default_setup>
</resources>
<session_save><![CDATA[files]]></session_save>
</global>
<admin>
<routers>
<adminhtml>
<args>
<frontName><![CDATA[admin]]></frontName>
</args>
</adminhtml>
</routers>
</admin>
</config>
为：
<?xml version="1.0"?>
<config>
<global>
// Other directives
<!-- This is a child node of config/global -->
<cache>
<backend>Cm_Cache_Backend_Redis</backend>
<backend_options>
<server>127.0.0.1</server> <!-- or absolute path to unix socket -->
<port>6379</port>
<database>0</database> <!-- Redis database number; protection against accidental data loss is improved by not sharing databases -->
<password></password> <!-- Specify if your server requires authentication -->
</backend_options>
</cache>
<!--session_save><![CDATA[files]]></session_save-->
<session_save>db</session_save>
<redis_session> <!-- All options seen here are the defaults -->
<host>127.0.0.1</host> <!-- Specify an absolute path if using a unix socket -->
<port>6379</port>
<password></password> <!-- Specify if your server requires authentication -->
<timeout>2.5</timeout> <!-- This is the connection timeout, not the locking timeout -->
<db>0</db> <!-- Redis database number; protection from accidental loss is improved by using a unique DB number for sessions -->
<compression_threshold>2048 </compression_threshold> <!-- Set to 0 to disable compression (recommended when suhosin.session.encrypt=on); known bug with strings over 64k: https://github.com/colinmollenhour/Cm_Cache_Backend_Redis/issues/18 -->
<compression_lib>gzip</compression_lib> <!-- gzip, lzf, lz4 or snappy -->
<log_level>1</log_level> <!-- 0 (emergency: system is unusable), 4 (warning; additional information, recommended), 5 (notice: normal but significant condition), 6 (info: informational messages), 7 (debug: the most information for development/testing) -->
<max_concurrency>6</max_concurrency> <!-- maximum number of processes that can wait for a lock on one session; for large production clusters, set this to at least 10% of the number of PHP processes -->
<break_after_frontend>5</break_after_frontend> <!-- seconds to wait for a session lock in the frontend; not as critical as admin -->
<fail_after>10</fail_after> <!-- seconds after which we bail from attempting to obtain lock (in addition to break after time) -->
<break_after_adminhtml>30</break_after_adminhtml>
<first_lifetime>600</first_lifetime> <!-- Lifetime of session for non-bots on the first write. 0 to disable -->
<bot_first_lifetime>60</bot_first_lifetime> <!-- Lifetime of session for bots on the first write. 0 to disable -->
<bot_lifetime>7200</bot_lifetime> <!-- Lifetime of session for bots on subsequent writes. 0 to disable -->
<disable_locking>0</disable_locking> <!-- Disable session locking entirely. -->
<min_lifetime>60</min_lifetime> <!-- Set the minimum session lifetime -->
<max_lifetime>2592000</max_lifetime> <!-- Set the maximum session lifetime -->
</redis_session>
</global>
<admin>
<routers>
<adminhtml>
<args>
<frontName><![CDATA[admin]]></frontName>
</args>
</adminhtml>
</routers>
</admin>
</config>
其次，通过运行以下命令清除会话的所有缓存：
rm -rf /var/www/html/magento/var/session/* rm -rf /var/www/html/magento/var/cache/*
第3步：重新启动并检查结果
接下来，您应该重新启动：
service redis-server restart
要检查Redis服务器是否正常工作，请输入：
redis-cli ping
如果结果是：
PONG
然后你的服务器正在响应。
此外，您可以通过以下方式监控所有流量：
redis-cli monitor
然后刷新页面。如果您可以在终端上看到生成的日志，有随机的字母数字字符，这意味着缓存正在运行。
您还可以检查 Redis-server是否能够设置密钥：
redis-cli 127.0.0.1:6379> set mykey KEY OK 127.0.0.1:6379> get mykey "KEY" 127.0.0.1:6379> exit
此外，您可以使用“info”命令获取服务器信息和统计信息：
redis-cli info
