redis 配置初体验

下载redis

1、新增start.bat
编辑redis-server redis.windows.conf

2、。改动redis.windows.conf配置文件改动password：找到例如以下行：
找到# requirepass foobared 去掉前面的凝视#。并把foobared 替换为你自己的password：admin

或者命令:

（mac系统安装完Redis后，在终端中输入：

$src/redis-server

即可启动Redis服务。）

3、启动start.bat

链接命令：redis-cli -h 127.0.0.1 -p 6379 -a admin

4、

commons-pool-1.5.6.jar
commons-pool2-2.0.jar
jedis-2.7.2.jar
junit-4.9b2.jar

5、
