Windows下Redis缓存服务器的使用 .NET StackExchange.Redis Redis Desktop Manager
Redis缓存服务器是一款key/value数据库，读110000次/s，写81000次/s，因为是内存操作所以速度飞快，常见用法有存用户令牌、短信验证码等
官网显示Redis本身并没有Windows版本的，微软官方开发了基于Windows的Redis服务器：MSOpenTech/redis
一、Redis服务端
首先下载Redis服务器，点击前往下载.msi版本，双击安装Redis服务端就有了，并以服务的形式随系统一起启动：
安装好Redis服务器之后第一件事就是设置密码，进入安装目录：C:\Program Files\Redis - 找到配置文件：redis.windows-service.conf - 找到：# requirepass foobared - 回车换行加上：requirepass 这里写自己的新密码（顶行写，前面不要留空格） - 到服务里重启Redis服务，或者重启电脑
不设置密码的坏处，看看携程这哥们的遭遇就知道了：记一次Redis被攻击的事件
二、Redis客户端（命令行和可视化工具RDM）
命令行方式演示：启动Redis客户端、读写Redis服务器
上图命令解释：
cd C:\Program Files\Redis：cd命令进入Redis安装目录，相当于Windows系统里双击进入Redis的安装目录
redis-cli.exe：打开redis-cli客户端程序，相当于Windows系统里双击运行一个exe程序（安装了上面的Redis服务端程序，需要一个客户端程序连接这个服务端。连接本机redis服务器直接敲此命令，连接远程的需要加ip和端口，例：redis-cli.exe -h 111.11.11.111 -p 6379）
keys *：查看所有键值对（如果Redis服务器设置了密码，这条命令会报错，需要先输入密码，执行此命令：auth 你的密码）
set blog oppoic.cnblogs.com：设置一个键值对，键是：blog，值是：oppoic.cnblogs.com（按目录存储：set 目录名:键 值）
get blog：获取键为blog对应的值
keys *：查看所有键值对
其他常用命令：
config get dir：获取redis安装目录
ping：返回PONG表示redis服务器正常
redis-cli.exe：进入第一个数据库（默认），redis一共0到15共16个库，进入第三个库 redis-cli -n 2（已经进去了，select 0~15 随意切换）
quit：退出redis程序
exit：退出dos窗口
flushdb：删除当前选择数据库中的所有key
flushall：删除所有数据库中的数据库
更多命令：https://redis.io/commands
至此，一个运行在本机的Redis缓存服务器已经搭建完成，并且可以读写了。但是命令行显然对小白用户不友好，可视化工具登场：Redis Desktop Manager
左侧树显示已经有一个连接了，点击底部的Connect to Redis Server再添加一个连接：
Name：连接名称，随便起
Host：主机地址，本机就是127.0.0.1，远程的输入对应IP
Port：端口，Redis服务器默认端口6379
Auth：密码，设置了就输，没设置留空
连上Redis服务器就可以看到，默认16个库（配置文件可改），索引从0开始。常见用法是一个项目一个库，项目下不同功能模块分不同目录存在这个库下。
有了可视化工具之后的操作就不用说了，双击，右键新建、删除。。。会用Windows系统的都会用这个工具。相比于命令行，Redis Desktop Manager这个可视化工具更友好，调试远程服务器上的数据也更方便，指哪打哪。
注：本机可以这样，连接远程服务器需要到服务器上的Redis安装目录下，找到redis.windows-service.conf文件，找到bind 127.0.0.1 前面加"#"注释掉，然后到服务里右键重启redis服务
三、C#操作Redis服务器
以上都是命令行和可视化工具操作Redis服务器，C#程序操作Redis需要借助StackExchange.Redis，为了统一调用，封装了一个RedisHelper帮助类：

String
RedisHelper.StringSet(CacheFolderEnum.Folder1, "string", "hello world", 60);
效果：
List
RedisHelper.ListRightPush(CacheFolderEnum.Folder2, "list", student1);
RedisHelper.ListRightPush(CacheFolderEnum.Folder2, "list", student2);
RedisHelper.ListRightPush(CacheFolderEnum.Folder2, "list", student3);
效果：
Hash
RedisHelper.HashSet<Student>(CacheFolderEnum.Folder3, "hash", "h1", student1);
RedisHelper.HashSet<Student>(CacheFolderEnum.Folder3, "hash", "h2", student2);
效果：
SortedSet
RedisHelper.SortedSetAdd<Student>(CacheFolderEnum.Folder3, "zsort", student1, 111);
RedisHelper.SortedSetAdd<Student>(CacheFolderEnum.Folder3, "zsort", student2, 99);
RedisHelper.SortedSetAdd<Student>(CacheFolderEnum.Folder3, "zsort", student3, 100);
效果：（有序集合。不管插入顺序，始终按照score排好顺序）
注：
1.把要操作的目录写到枚举里，方便程序统一调用，不容易出错。如果多个目录嵌套就在Description上写[Description("一级目录:二级目录:三级目录")]
2.配置文件里的redis_store_db节点表示默认存在哪个库里，帮助类的每个方法也单独接收db参数，方便个性化存储到特定库
