Redis缓存服务搭建及实现数据读写

发现博客园中好多大牛在介绍自己的开源项目是很少用到缓存，比如Memcached、Redis、mongodb等，今天得空抽时间把Redis缓存研究了一下，写下来总结一下，跟大家一起分享 一下。由于小弟水平有限又是第一次接触Redis，有些的不对的地方欢迎指出纠正。

1、 下载安装Redis

下载地址：https://github.com/MSOpenTech/Redis。

2、 安装Redis

在下载的文件中找到bin并打开。

　　


redis-server.exe：服务程序(目前我们只用到这一个)

redis-check-dump.exe：本地数据库检查

redis-check-aof.exe：更新日志检查

redis-benchmark.exe：性能测试，用以模拟同时由N个客户端发送M个 SETs/GETs 查询 (类似于 Apache 的ab 工具).

Redis有很多配置参数，这里就不介绍了，有兴趣的朋友可以到网上查查。

双击redis-server.exe或者在命令窗口中输入D:\redis-2.6\redis-server.exe即可启动Redis服务。



注意端口号：Port：6379 在我们的程序中会用到该端口号。

3、 数据读、写、删测试，并实现list存数。

首先引用下面四个DLL文件

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using ServiceStack.Redis;
using ServiceStack.Text;
using ServiceStack.Redis.Generic;

namespace RedisStudy
{
public class RedisHelper:IDisposable
{
public RedisClient Redis = new RedisClient("127.0.0.1", 6379);
//缓存池
PooledRedisClientManager prcm = new PooledRedisClientManager();

//默认缓存过期时间单位秒
public int secondsTimeOut = 30 * 60;

/// <summary>
/// 缓冲池
/// </summary>
/// <param name="readWriteHosts"></param>
/// <param name="readOnlyHosts"></param>
/// <returns></returns>
public static PooledRedisClientManager CreateManager(
string[] readWriteHosts, string[] readOnlyHosts)
{
return new PooledRedisClientManager(readWriteHosts, readOnlyHosts,
new RedisClientManagerConfig
{
MaxWritePoolSize = readWriteHosts.Length * 5,
MaxReadPoolSize = readOnlyHosts.Length * 5,
AutoStart = true,
});// { RedisClientFactory = (IRedisClientFactory)RedisCacheClientFactory.Instance.CreateRedisClient("127.0.0.1", 6379) };
}
/// <summary>
/// 构造函数
/// </summary>
/// <param name="OpenPooledRedis">是否开启缓冲池</param>
public RedisHelper(bool OpenPooledRedis=false)
{

if (OpenPooledRedis)
{
prcm = CreateManager(new string[] { "127.0.0.1:6379" }, new string[] { "127.0.0.1:6379" });
Redis = prcm.GetClient() as RedisClient;
}
}

}

public bool Add<T>(string key, T t, int timeout)
{
if (timeout >= 0)
{
if (timeout > 0)
{
secondsTimeOut = timeout;
}
Redis.Expire(key, secondsTimeOut);
}
return Redis.Add<T>(key, t);
}

}
}
#endregion
//释放资源
public void Dispose()
{
if (Redis != null)
{

}
}
}

4、 测试

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Threading;

namespace RedisStudy
{
public class User
{
public string Name { get; set; }
public int Id { get; set; }
}

class Program
{
static RedisHelper redisHelper = new RedisHelper(true);

static void Main(string[] args)
{
User u = new User() { Name = "eric1", Id = 1 };
redisHelper.Set<User>("user", u);//设置缓存
u=redisHelper.Get<User>("user");
Console.WriteLine(u.Name);

List<User> list = new List<User>()
{
new User(){Name="eric1",Id=1},
new User(){Name="eric2",Id=2}
};

redisHelper.Remove("list1");//删除缓存
redisHelper.AddList<User>("list1", list);//添加缓存链表
redisHelper.AddEntityToList<User>("list1", new User() { Name = "eric3",Id=3 });
list = redisHelper.GetList<User>("list1").ToList();
Console.WriteLine(list.Count);

redisHelper.RemoveEntityFromList<User>("list1", list[0]);
redisHelper.RemoveEntityFromList<User>("list1", it => it.Id == 2);
list = redisHelper.GetList<User>("list1").ToList();
Console.WriteLine(list.Count);

redisHelper.Dispose();
Console.ReadLine();

}

}
}

整篇文章写的比较仓促，很多基本点都没有说明，有不懂的请百度一下。
