redis 应用

1：首先下载redis:redis-2.0.2.zip(32bit)，解压。

从下面地址下：http://code.google.com/p/servicestack/wiki/RedisWindowsDownload，看到下面有redis-2.0.2.zip(32bit)，就是他了，下载完成后，解压到D:\redis-2.0.2.

2：创建redis.conf文件：

这是一个配置文件，指定了redis的监听端口，timeout等。如下面有：port6379。

把下面内容COPY到一新建文件中，取名redis.conf,再保存到redis-2.0.2目录下：

3：在cmd下面执行以下命令，指定它使用我们的redis.conf，同时也是启动，把redis运行起来，这里指定用redis.conf的配置运行服务器

D:\redis-2.0.2>redis-server.exeredis.conf

4:开一新DOS窗口cmd.执行以下命令，这是Redis的客户端程序：

redis-cli.exe-h172.18.5.1-p6379

172.18.5.1是我本机IP地址，端口6379就是上面配置文件中指定的监听端口

执行完成后，应该能看到redis启动了，这时在第一个cmd窗口可以看到连接信息。

执行一条保存keyvalue操作

setmystock300156

再查询一下

getmystock
