Redis 小白指南（一）- 简介、安装、GUI 和 C# 驱动介绍

简介

　　ANSI C 编写，开源，基于内存，可持久化，一个键值对的数据库，用法简单。

　　支持的类型：字符串、散列、列表、集合和有序集合。

　　因为 Redis 默认将所有数据都存储到内存中，并且内存的读写速度远远高于硬盘，因此，比其他基于硬盘存储的数据库在性能上体现的优势非常明显。不过这样也引发了一个数据安全性的问题，程序异常或退出后数据会出现丢失的情形，现在新的版本已经提供了数据持久化（RDB + AOF）的支持，即可以将内存中的数据异步写入到硬盘上，同时不会影响其它功能的运行。

　　redis 可以为每个键设置生存时间，到期自动删除，也就是说可以作为缓存系统（这也是企业主要的运用场景）进行使用。

　　相对于 Memcached，简单的说：Redis 单线程模型，Memcached 支持多线程，但 Redis 支持的功能和数据类型更多，更简单易用，并且 redis 的性能在绝大部分场合下都不会成为系统瓶颈，不过在多核服务器上使用的情况下，理论上 Memcached 比 redis 性能更高。所以，在新项目中，建议使用 redis 代替 Memcached。

　　Redis 还可以限定数据占用的最大内存空间，在数据达到空间限制后按一定规则自动淘汰不需要的键；也支持构建高性能的队列（不过很多企业会选择第三方的 MQ，如：RabbitMQ）。

安装

　　它的约定次版本号（即第一个小数点后的数字）为偶数的版本是稳定版（如 v2.8，v3.0）。

　　为了减少学习成本，我们直接使用 windows 版本的就可以，想学习 Linux 部署的，先搜搜别人的文章吧。

　　redis-windows-3.0（搜索了一下，最新的正式版是 3.2）：下载地址

　　文件简单说明：

入门指令

　　1.启动 CMD：

$ redis-server

$ redis-server --port 6380 //自定义端口

　　2.停止：

$ redis-cli SHUTDOWN

　　3.PING 命令：

　　测试与 redis 的连接是否正常，正常返回 PONG

$ redis-cli PING

GUI 工具

　　Redis Client：一个基于Java SWT 和 Jedis 编写的 redis 客户端 GUI 工具。可从 https://github.com/caoxinyu/RedisClient 下载。

　　从图可知，redis 包含了 16 个数据库。上面的每个数据库默认从 0 开始的递增数字命名。

　　因为该程序打包后的压缩包 >10 M，无法上传到 cnblogs，如有需要的童鞋请加群在群文件中下载压缩包。

　　补充一下园友（心态要好）推荐的其它 GUI 工具 RedisDeskTopManager：https://redisdesktop.com/download。

C# 驱动

　　之前在《使用 StackExchange.Redis 封装属于自己的 RedisHelper》曾经发布了一篇使用 StackExchange.Redis 进行了简单封装的 RedisHelper，你可以选择查看之前的文章，从中借鉴一些思想或者给出一些建议。

　　这里是更新后的 Helper 代码（直接展开即可），代码的后续更新在 GitHub 上。
