一、下载安装Redis（windows版本）
1、下载地址：https://github.com/MicrosoftArchive/redis/releases
2、安装：
1）打开运行窗口，输出cmd，进入DOS命令窗口。然后打开至redis目录，执行redis-service redis.windows.conf命令（下图为安装成功）。
2）这个窗口要保持开启关闭时redis服务会自动关闭，所以需要把redis添加到windows服务（可以保存成两个bat批处理文件）。
安装命令：redis-server.exe --service-install redis.windows.conf --loglevel verbose
卸载命令：redis-server --service-uninstall
二、.net环境应用，以ServiceStack.Redis类库为例（功能：删除商品下Key值为xxxxx的缓存）。
1、定义redis单独配置文件。
1）web.config
2）redis.config
2、定义RedisSection类，redis相关属性等。
namespace Demo.Util
{
public class RedisSection : ConfigurationSection
{
private static RedisSection _instance; public static RedisSection Instatce
{
get
{
_instance = ConfigurationManager.GetSection("redissection") as RedisSection;
return _instance;
}
} /// <summary>
/// 服务器
/// </summary>
[ConfigurationProperty("host", IsRequired = true)]
public string Host
{
get { return this["host"].ToString(); }
} /// <summary>
/// 端口号
/// </summary>
[ConfigurationProperty("port", IsRequired = true)]
public string Port
{
get { return this["port"].ToString(); }
} /// <summary>
/// 密码
/// </summary>
[ConfigurationProperty("password", IsRequired = false)]
public string Password
{
get { return this["password"].ToString(); }
} /// <summary>
/// 过期时间 单位：小时
/// </summary>
[ConfigurationProperty("expireTime", IsRequired = false)]
public int ExpireTime
{
get { return int.Parse(this["expireTime"].ToString()); }
} /// <summary>
/// 最大写链接数
/// </summary>
[ConfigurationProperty("MaxWritePoolSize", IsRequired = false, DefaultValue = )]
public int MaxWritePoolSize
{
get
{
int maxWritePoolSize = (int)base["MaxWritePoolSize"];
return maxWritePoolSize > ? maxWritePoolSize : ;
}
set
{
base["MaxWritePoolSize"] = value;
}
} /// <summary>
/// 最大读链接数
/// </summary>
[ConfigurationProperty("MaxReadPoolSize", IsRequired = false, DefaultValue = )]
public int MaxReadPoolSize
{
get
{
int maxReadPoolSize = (int)base["MaxReadPoolSize"];
return maxReadPoolSize > ? maxReadPoolSize : ;
}
set
{
base["MaxReadPoolSize"] = value;
}
} /// <summary>
/// 自动重启
/// </summary>
[ConfigurationProperty("AutoStart", IsRequired = false, DefaultValue = true)]
public bool AutoStart
{
get
{
return (bool)base["AutoStart"];
}
set
{
base["AutoStart"] = value;
}
} [ConfigurationProperty("keys", IsDefaultCollection = true)]
public KeyCollection Keys
{
get { return this["keys"] as KeyCollection; }
}
} public class KeyCollection : ConfigurationElementCollection
{
protected override ConfigurationElement CreateNewElement()
{
return new KeyElement();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((KeyElement)element).Name;
} public KeyElement this[int index]
{
get
{
return this.BaseGet(index) as KeyElement;
}
}
new public KeyElement this[string Name]
{
get
{
return (KeyElement)BaseGet(Name);
}
}
new public int Count
{
get { return base.Count; }
}
} public class KeyElement : ConfigurationElement
{
[ConfigurationProperty("name", IsRequired = false)]
public string Name
{
get { return this["name"].ToString(); }
} [ConfigurationProperty("key", IsRequired = true)]
public string Key
{
get { return this["key"].ToString(); }
}
}
}
3、定义RedisHelper类，redis相关操作。
public class RedisHelper
{ private static string password = string.IsNullOrEmpty(RedisSection.Instatce.Password) ? "" : RedisSection.Instatce.Password + "@"; //Redis服务器和端口号（密码@127.0.0.1:6379）
private static string RedisPath = string.Format("{0}:{1}", password + RedisSection.Instatce.Host, RedisSection.Instatce.Port); //过期时间（小时）
//private static int ExpireTime = RedisSection.Instatce.ExpireTime; private static PooledRedisClientManager prcm = CreateManager(new string[] { RedisPath }, new string[] { RedisPath }); /// <summary>
/// 缓存池
/// </summary>
/// <param name="readWriteHosts">“写”链接池链接数</param>
/// <param name="readOnlyHosts">“读”链接池链接数</param>
/// <returns></returns>
private static PooledRedisClientManager CreateManager(string[] readWriteHosts, string[] readOnlyHosts)
{
// 支持读写分离，均衡负载
return new PooledRedisClientManager(readWriteHosts, readOnlyHosts, new RedisClientManagerConfig
{
MaxWritePoolSize = RedisSection.Instatce.MaxWritePoolSize,
MaxReadPoolSize = RedisSection.Instatce.MaxReadPoolSize,
AutoStart = RedisSection.Instatce.AutoStart
});
} public static void Remove(string key)
{
using (var redis = prcm.GetClient())
{
redis.Remove(key);
}
} public static void RemoveAll(IEnumerable<string> keys)
{
using (var redis = prcm.GetClient())
{
redis.RemoveAll(keys);
}
} }
4、使用
var key = RedisSection.Instatce.Keys["product"].Key;
Util.Redis.RedisHelper.Remove(key);
