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", );

List

RedisHelper.ListRightPush(CacheFolderEnum.Folder2, "list", student1);
RedisHelper.ListRightPush(CacheFolderEnum.Folder2, "list", student2);
RedisHelper.ListRightPush(CacheFolderEnum.Folder2, "list", student3);

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, );
RedisHelper.SortedSetAdd<Student>(CacheFolderEnum.Folder3, "zsort", student2, );
RedisHelper.SortedSetAdd<Student>(CacheFolderEnum.Folder3, "zsort", student3, );

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
