• [转]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 FilesRedis - 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 FilesRedis: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
