Windows上使用C#访问ubuntu上的redis数据库

it2024-08-08 52

一、在win中安装redis数据库

1、在windows上安装Redis,由于博客园不支持上传msi文件，所以我把后缀改为了rar,下载下来的时候别忘了将rar改为msi，安装的时候把加入到环境变量勾选上。 2、安装好后，win+r打开运行输入cmd进入控制台程序，直接输入redis-cli并且输入ping，回复pong则链接成功，

1、简单字符串存取 set key value get key ···

3、安装RedisStudio，redis管理界面，个人觉得最好使用的。

二、在ubuntu中安装redis数据库

1、在Vmware中安装Ubuntu虚拟机； 2、安装redis

//下载redis-3.2.6 sudo wget http://download.redis.io/releases/redis-3.2.6.tar.gz //解压redis-3.2.6 sudo tar -zxvf redis-3.2.6.tar.gz

3、在~/下新建一个redis文件夹并且将redis-3.2.6下的文件全部拷贝进该redis文件夹下

//如果没有安装gcc sudo apt-get install gcc //进入redis文件夹执行make sudo make sudo make install

4、此时就将redis安装到了/usr/local/bin（服务端，客户端都在里面启动）下了

//进入/usr/local/bin文件夹中 cd /usr/local/bin //启动redis-server redis-server ~/redis/redis.conf redis-cli

5、为了能在我们的win中访问linux下的redis，我们还需要对redis.conf进行少量的更改

protected-mode yes --> protected-mode no bind 127.0.0.1 --> #bind 127.0.0.1

6、在终端输入ifconfig，查看ubuntu的IP地址inet addr:xxx.xxx.xxx.xxx

三、C#使用redis

1、Nuget安装StackExchange.Redis,程序中加入SeRedisHelper类

2、使用

/**************************************************************** * 作者：xuxuzhaozhao * CLR 版本：4.0.30319.42000 * 创建时间：2017/5/8 10:30:26 * 当前版本：1.0.0.1 * * 描述说明： * * 修改历史： * *****************************************************************/ using System; using Common.Redis; namespace Redis.Test { class Program { static void Main(string[] args) { var loginUser = new LoginUser { Id = 1, Name = "xuxuzhaozhao", Gender = true, CreateTime = DateTime.Today, Money = 12.12M }; var updateUser = new LoginUser { Id = 2, Name = "xuchengyi", Gender = false, CreateTime = DateTime.Now, Money = 19.92M }; while (true) { Console.WriteLine(); Console.WriteLine("========================================"); Console.WriteLine("请输入想要对实体进行的操作："); Console.WriteLine("1、将实体加入Redis；"); Console.WriteLine("2、从Redis查询实体；"); Console.WriteLine("3、从Redis更改实体；"); Console.WriteLine("4、从Redis删除实体；"); Console.WriteLine("======================================="); var op = Console.ReadLine(); switch (op) { case "1": Console.WriteLine("请输入键名："); var key1 = Console.ReadLine(); if(SERedisHelper.Set(key1,loginUser,new TimeSpan(0,0,30,0))) Console.WriteLine("实体成功加入Redis！过期时间为30分钟！"); else Console.WriteLine("加入失败！"); break; case "2": Console.WriteLine("请输入要查询值对应的键："); var key2 = Console.ReadLine(); LoginUser user = SERedisHelper.GetEntityBykey<LoginUser>(key2); if (user != null) { Console.WriteLine("查询成功！实体信息如下："); Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(user)); } else Console.WriteLine("没有查询到{0}对应的实体！",key2); break; case "3": Console.WriteLine("请输入要更改的键："); var key3 = Console.ReadLine(); if(SERedisHelper.Set(key3,updateUser,new TimeSpan(0, 0, 30, 0))) Console.WriteLine("实体更新成功！"); else Console.WriteLine("更新失败！"); break; case "4": Console.WriteLine("请输入要删除实体对应的键："); var key4 = Console.ReadLine(); if (SERedisHelper.DeleteKey(key4)) Console.WriteLine("实体删除成功！"); else Console.WriteLine("删除失败！"); break; default: Console.WriteLine("请输入数字进行操作！"); break; } } } } class LoginUser { public int Id { get; set; } public string Name { get; set; } public bool Gender { get; set; } public DateTime CreateTime { get; set; } public decimal Money { get; set; } } }
