分布式缓存系统Memcached简介与实践

Memcached的使用
一 Memcached服务器端的安装（此处将其作为系统服务安装）
下载文件：memcached 1.2.1 for Win32 binaries (Dec 23, 2006)
   1 解压缩文件到c:\memcached
   2 命令行输入 'c:\memcached\memcached.exe -d install'
   3 命令行输入 'c:\memcached\memcached.exe -d start' ，该命令启动 Memcached ，默认监听端口为 11211
通过 memcached.exe -h 可以查看其帮助
二   .NET memcached client library
   下载文件：https://sourceforge.net/projects/memcacheddotnet/

里面有.net1.1 和 .net2.0的两种版本还有一个不错的例子。

三应用

1 将Commons.dll，ICSharpCode.SharpZipLib.dll，log4net.dll，Memcached.ClientLibrary.dll 等放到bin目录
2 引用Memcached.ClientLibrary.dll
3 代码

1 namespace Memcached.MemcachedBench
2 {
3     using System;
4     using System.Collections;
5
6     using Memcached.ClientLibrary;
7
8     public class MemcachedBench
9     {
10         [STAThread]
11         public static void Main(String[] args)
12         {
13             string[] serverlist = { "10.0.0.131:11211", "10.0.0.132:11211" };
14
15             //初始化池
16             SockIOPool pool = SockIOPool.GetInstance();
17             pool.SetServers(serverlist);
18
19             pool.InitConnections = 3;
20             pool.MinConnections = 3;
21             pool.MaxConnections = 5;
22
23             pool.SocketConnectTimeout = 1000;
24             pool.SocketTimeout = 3000;
25
26             pool.MaintenanceSleep = 30;
27             pool.Failover = true;
28
29             pool.Nagle = false;
30             pool.Initialize();
31
32             // 获得客户端实例
33             MemcachedClient mc = new MemcachedClient();
34             mc.EnableCompression = false;
35
36             Console.WriteLine("------------测  试-----------");
37             mc.Set("test", "my value");  //存储数据到缓存服务器，这里将字符串"my value"缓存，key 是"test"
38
39             if (mc.KeyExists("test"))   //测试缓存存在key为test的项目
40             {
41                 Console.WriteLine("test is Exists");
42                 Console.WriteLine(mc.Get("test").ToString());  //在缓存中获取key为test的项目
43             }
44             else
45             {
46                 Console.WriteLine("test not Exists");
47             }
48
49             Console.ReadLine();
50
51             mc.Delete("test");  //移除缓存中key为test的项目
52
53             if (mc.KeyExists("test"))
54             {
55                 Console.WriteLine("test is Exists");
56                 Console.WriteLine(mc.Get("test").ToString());
57             }
58             else
59             {
60                 Console.WriteLine("test not Exists");
61             }
62             Console.ReadLine();
63
64             SockIOPool.GetInstance().Shutdown();  //关闭池，关闭sockets
65         }
66     }
67 }

static void Main(string[] args)
       {
           string[] serverlist = { "192.168.0.129:11211" };
           //初始化池
           SockIOPool sock = SockIOPool.GetInstance();
           sock.SetServers(serverlist);

           sock.InitConnections = 3;
           sock.MinConnections = 3;
           sock.MaxConnections = 5;

           sock.SocketConnectTimeout = 1000;
           sock.SocketTimeout = 3000;

           sock.MaintenanceSleep = 30;
           sock.Failover = true;

           sock.Nagle = false;
           sock.Initialize();

           //获取客户端实例

           MemcachedClient memcached = new MemcachedClient();
           memcached.EnableCompression = false;

           Console.WriteLine("-------Memcached测试-------");
           memcached.Set("key1", "Value1");
           if (memcached.KeyExists("key1"))
           {
               Console.WriteLine("存在key1..");
               Console.WriteLine(memcached.Get("key1").ToString());
           }
           else 
           {
               Console.WriteLine("不存在key1键");
           }

           Console.Read();
           SockIOPool.GetInstance().Shutdown();  //关闭池， 关闭sockets
}
