windows下安装redis
下载地址https://github.com/dmajkic/redis/downloads。下载到的Redis支持32bit和64bit。根据自己实际情况选择，我选择64bit。把64bit文件内容拷贝到需要安装的目录下E:\molly\redis\redis-windows
打开一个cmd窗口，使用cd命令切换到指定目录（E:\molly\redis\redis-windows）运行 redis-server.exe redis.conf 。运行以后出现如下界面
这就说明Redis服务端已经安装成功。
重新打开一个cmd窗口，使用cd命令切换到指定目录（E:\molly\redis\redis-windows）运行 redis-cli.exe
-h 127.0.0.1 -p 6379，其中 127.0.0.1是本地ip，6379是redis服务端的默认端口。运行成功如下图所示。
这样，Redis windows环境下搭建已经完成，是不是很简单。
环境已经搭建好，总得测试下吧。比如：存储一个key为test，value为hello word的字符串，然后获取key值
正确输出 hell word，测试成功！
3.java应用redis
Jedis 是 Redis 官方首选的 Java 客户端开发包
开发前置准备工作：
使用Java操作Redis需要jedis-2.1.0.jar，如果需要使用Redis连接池的话，还需commons-pool-1.5.4.jar，下载地址：可以参考我的下载资源，也可以自己网页下载
