解压文件到指定的目录，D:\\ChromeCoreDownloads\\Redis-x64-3.2.100（根据自己情况定）

### 将该目录加入到环境变量中 ：计算机—属性—高级系统设置—高级—环境变量—找到path，在末尾添加 ###

# 在新的cmd中输入redis-cli.exe -h 127.0.0.1 -p 6379 连接数据库 #

### 2增加元素 lpush data\_base a b c(左边插入三个元素a，b，c):先进后出，rpush data\_base x y z(左边插入三个元素x，y，z)：先进先出 ###

### 4删除元素：lpop data\_base 左边删除一个元素的 rpop表示右边删除一个元素 ###
