1.简单介绍
Redis是一个开源,高级的键值存储和一个适用的解决方案,用于构建高性能,可扩展的Web应用程序。
Redis有三个主要特点,使它优越于其它键值数据存储系统 -
- Redis将其数据库完全保存在内存中,仅使用磁盘进行持久化。
- 与其它键值数据存储相比,Redis有一组相对丰富的数据类型。
- Redis可以将数据复制到任意数量的从机中。
2.安装redis服务
下载文件Redis-x64-3.2.100.msi
3.常用redis命令
卸载服务:redis-server --service-uninstall
开启服务:redis-server --service-start
停止服务:redis-server --service-stop
4.安装redis可视化工具
redis-desktop-manager-0.8.8.384.exe
5.存取数据
