在《memc_nginx+srcache_nginx+memcached构建透明的动态页面缓存》一文中，我们使用到memcached来作为缓存载体。想必大家都知道memcached有存储大小的限制，不得超过1M。 本文将使用redis来作为缓存载体。nginx的srcache_nginx模块指令参数解释参见《memc_nginx+srcache_nginx+memcached构建透明的动态页面缓存》。
1. nginx模块

nginx模块安装参见ttlsa.com中相关文档。
2. redis安装配置
安装步骤参见：http://www.ttlsa.com/html/1646.html
配置参数解释参见：http://www.ttlsa.com/html/1226.html
配置实例：

由于只把redis当做缓存使用，因此没有启用持久化。
3. nginx配置

4. 测试
没有做缓存状态：
有做缓存状态：
5. 响应头状态
第一次请求：
再次请求：
6. 查看redis是否缓存以及过期时间
