magento + redis 安装

1

////////////wget http://redis.googlecode.com/files/redis-2.4.11.tar.gz

wget http://redis.googlecode.com/files/redis-2.6.14.tar.gztar xzf redis-2.6.14.tar.gzcd redis-2.6.14make

2

cd srccp redis-server /usr/local/bin/cp redis-cli /usr/local/bin/

3

mkdir /etc/redismkdir /var/redismkdir /var/redis/6379

4

cd ..cp utils/redis_init_script /etc/init.d/redis_6379cp redis.conf /etc/redis/6379.conf

开机启动：

/etc/init.d/redis_6379 start

5

vim /etc/redis/6379.confdaemonize to yespidfile to /var/run/redis_6379.pidlogfile to /var/log/redis_6379.logdir to /var/redis/6379maxmemory 268435456

maxmemory to some value appropriate for your system (otherwise it will gobble it all up) example:268435456(256MB)

上面下载的文件和下面这个，可以在资源里面下载：http://download.csdn.net/download/terry_water/6775255，我已经下载好了

//如果下面的git运行报错，找不到命令，那么安装git  yum install git

git clone git://github.com/owlient/phprediscd phpredis

/usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-configmake && make install 

如果安装了php的多线程模块，上面的地址可能会报错：/www/tools/phpredis/redis.c:4284: error: too many arguments to function ‘redis_serialize’

那么使用这个地址：下载redis的地址：

 git clone git://github.com/nicolasff/phpredis

/etc/php.ini  添加：

extension=redis.so 

7

git clone git://github.com/colinmollenhour/Cm_Cache_Backend_Redis.gitmkdir /www/web/test/magento/app/code/community/Cm/Cachemkdir /www/web/test/magento/app/code/community/Cm/Cache/Backend/mv Cm_Cache_Backend_Redis/Cm/Cache/Backend/* /www/web/test/magento/app/code/community/Cm/Cache/Backend/ 

上面就是 app/code/community/Cm/Cache/Backend/Redis.php

可以直接来这里下载：

下载一：原始版本：http://download.csdn.net/detail/terry_water/7695041

下载二：如果原始版本报错sAdd 4paramster，那么使用下载二：在Client.php 860行，注释代码：

 // if($argsFlat !== NULL) {                    //    $args = $argsFlat;                    //    $argsFlat = NULL;                    //}

修改配置文件

vim /etc/sysctl.conf

添加

vm.overcommit_memory=1

刷新配置使之生效

sysctl vm.overcommit_memory=1 

app/ect/local.xml:

global标签内添加：

重启linux（上面的所有配置都重启了，笨办法）
启动：

redis-server /etc/redis/6379.conf

关闭redis

/usr/local/bin/redis-cli -h 127.0.0.1 -p 6379 shutdown

清空缓存redis

redis-cli flushall

如果想清空缓存，重启redis是没有作用的，需要执行清空缓存命令，这点和memcache不一样

查看：
redis-cli info
使用参考资料

命令中文参考：

其他：
redis-server：Redis服务器的daemon启动程序
    redis-cli：Redis命令行操作工具。当然，你也可以用telnet根据其纯文本协议来操作
    redis-benchmark：Redis性能测试工具，测试Redis在你的系统及你的配置下的读写性能
    redis-stat：Redis状态检测工具，可以检测Redis当前状态参数及延迟状况 


内核参数说明如下：


overcommit_memory文件指定了内核针对内存分配的策略，其值可以是0、1、2。
0， 表示内核将检查是否有足够的可用内存供应用进程使用；如果有足够的可用内存，内存申请允许；否则，内存申请失败，并把错误返回给应用进程。
1， 表示内核允许分配所有的物理内存，而不管当前的内存状态如何。
2， 表示内核允许分配超过所有物理内存和交换空间总和的内存


 **编辑redis.conf配置文件（/etc/redis.conf），按需求做出适当调整，比如：
daemonize yes #转为守护进程，否则启动时会每隔5秒输出一行监控信息
save 60 1000 #减小改变次数，其实这个可以根据情况进行指定
maxmemory 256000000 #分配256M内存


在我们成功安装Redis后，我们直接执行redis-server即可运行Redis，此时它是按照默认配置来运行的（默认配置甚至不是后台运 行）。我们希望Redis按我们的要求运行，则我们需要修改配置文件，Redis的配置文件就是我们上面第二个cp操作的redis.conf文件，目前 它被我们拷贝到了/usr/local/redis/etc/目录下。修改它就可以配置我们的server了。如何修改？下面是redis.conf的主 要配置参数的意义：


    daemonize：是否以后台daemon方式运行
    pidfile：pid文件位置
    port：监听的端口号
    timeout：请求超时时间
    loglevel：log信息级别
    logfile：log文件位置
    databases：开启数据库的数量
    save * *：保存快照的频率，第一个*表示多长时间，第三个*表示执行多少次写操作。在一定时间内执行一定数量的写操作时，自动保存快照。可设置多个条件。
    rdbcompression：是否使用压缩
    dbfilename：数据快照文件名（只是文件名，不包括目录）
    dir：数据快照的保存目录（这个是目录）
    appendonly：是否开启appendonlylog，开启的话每次写操作会记一条log，这会提高数据抗风险能力，但影响效率。
    appendfsync：appendonlylog如何同步到磁盘（三个选项，分别是每次写都强制调用fsync、每秒启用一次fsync、不调用fsync等待系统自己同步）
