redis服务器环境下mysql实现lnmp架构缓存

这篇文章主要介绍了redis系统环境下mysql实现lnmp架构缓存,本文给大家介绍的非常详细,具有一定的参考借鉴价值,需要的朋友可以参考下

配置环境:redhat6.5

server1:redis(172.25.254.1)

server2:php(172.25.254.2)

server3:mysql(172.25.254.3)

配置步骤:

server2:

1、server2安装php的redis相应模块

测试:访问172.25.254.2/test.php

1、php默认从redis 索取数据,第一次redis无缓存,则php从mysql'索取数据

第一次无缓存

第二次索取数据后:

以上redis 作为 mysql 的缓存服务器,但是如果更新了 mysql,redis中仍然会有对应的 KEY,数据就不会更新,此时就会出现 mysql 和 redis 数据不一致的情况。
