Redis安装：http://www.runoob.com/redis/redis-install.html

Configuration:https://www.cnblogs.com/ArvinZhao/p/6007043.html

Redis可视化工具Redis Desktop Manager：https://redisdesktop.com/download

千万要记住，给Redis设置访问密码，Redis的连接字符串中也要设置好密码。

Redis设置密码：https://blog.csdn.net/qq_35357001/article/details/56835919

启动服务：dos中 cd Redis安装目录，运行 redis-server.exe redis.windows.conf；

启动命令：dos中 cd Redis安装目录，运行 redis-cli.exe -h 127.0.0.1 -p 6379；

设置密码：config set requirepass xsj10011 注意：密码尽量设置长一点

获取密码：config get requirepass  注意：获取密码之前需要先验证密码，不然获取不到

验证密码：auth xsj10011

密码改变之后，代码中的连接字符串里的密码也要对应改变，不然操作不了Redis。对应的可视化工具里的密码也要改。

1.打开VS的NuGet》搜索：StackExchange.Redis，安装到项目中

2.配置文件：

<appSettings>

    <!-- 系统前缀 -->

    <add key="redisKey" value="jay"/>

  </appSettings>

  <connectionStrings>

    <!-- Redis连接字符串 -->

    <add name="RedisExchangeHosts" connectionString="127.0.0.1:6379,allowadmin=true,password=xsj10011,keepAlive=180"/>

  </connectionStrings>

web.config

RedisHelper

4.使用

[HttpPost]

        public JsonResult SetV()

        {

            bool result = new RedisCommon.RedisHelper().StringSet("name", "jay.star");

            return Json("result:" + result, JsonRequestBehavior.AllowGet);

        }

        [HttpGet]

        public JsonResult GetV()

        {

            string name = new RedisCommon.RedisHelper().StringGet("name");

            return Json("name:" + name, JsonRequestBehavior.AllowGet);

        }
