Memcache分布式实战

Ps：经过半天的努力，终于初窥memcache门径，记录分享。

三部曲<大纲>

1、安装服务

2、WebConfig配置

3、程序中引用相应dll

4、编码

5、telnet中监测

1、安装参考  http://www.2cto.com/os/201205/132641.html

    1）安装比较简单无难度，参考上面博文的步骤，应该没有问题。

2、WebConfig中配置是关键，参考如下代码

    <modules runAllManagedModulesForAllRequests="true"/>

</configuration>

 

3、引用dll

 

4、编码

  1）application start中添加如下代码

    

  void Application_Start(object sender, EventArgs e)
        {
            // Code that runs on application startup
            try
            {
                string[] serverlist = new string[] { "192.168.1.216:11211" }; ;

                string poolName = "MemcacheIOPool";
                // initialize the pool for memcache servers

                SockIOPool pool = SockIOPool.GetInstance(poolName);

                //设置连接池的初始容量，最小容量，最大容量，Socket 读取超时时间，Socket连接超时时间

                pool.SetServers(serverlist);

                pool.InitConnections = 1;

                pool.MinConnections = 1;

                pool.MaxConnections = 500;

                pool.SocketConnectTimeout = 1000;

                pool.SocketTimeout = 3000;

                pool.MaintenanceSleep = 30;//表示是否需要延时结束

                pool.Failover = true;//表示对于服务器出现问题时的自动修复。

                pool.Nagle = false;

                pool.Initialize();//容器初始化
            }
            catch (Exception err)
            {
                log4net.ILog log = log4net.LogManager.GetLogger("log");
                log.Info(err);
            }
        }

 

  2) set cookie

 1  public partial class _Default : System.Web.UI.Page
 2     {
 3         string poolName = "MemcacheIOPool";
 4         // [STAThread]
 5         protected void Page_Load(object sender, EventArgs e)
 6         {
 7             MemcachedClient mc = new MemcachedClient();//实例化一个客户端
 8 
 9             mc.PoolName = poolName;
10 
11             mc.EnableCompression = false;
12 
13             string key = "user_info";//key值
14 
15             object obj = new object();
16 
17             if (!mc.KeyExists(key)) //测试缓存中是否存在key的值
18             {
19                 mc.Add("list", CreateListInt(), System.DateTime.Now.AddMinutes(30));
20                 mc.Set("dd", "cc", System.DateTime.Now.AddMinutes(30));
21                 mc.Set("dic", CreateDic(), System.DateTime.Now.AddMinutes(30));
22             }
23         }
24 
25         protected List<int> CreateListInt()
26         {
27             int[] intArray = new int[] { 1, 2, 3, 4, 5, 6, 6, 7, 8, 9, 11 };
28             List<int> list = new List<int>();
29             foreach (int item in intArray)
30             {
31                 list.Add(item);
32             }
33             return list;
34         }
35 
36         protected Dictionary<int, string> CreateDic()
37         {
38             Dictionary<int, string> dic = new Dictionary<int, string>();
39             dic.Add(1, "hacksl");
40             dic.Add(2, "magusW");
41             dic.Add(3, "jack");
42             dic.Add(4, "helen");
43             return dic;
44         }

5、TelNet中监测

    开启telnet服务 http://jingyan.baidu.com/article/8065f87fc3b31123312498e5.html

    1） cmd 中 输入 telnet 192.168.1.xx 11211

    2) http://www.cnblogs.com/jeffwongishandsome/archive/2011/11/06/2238265.html 可参考这里面的命令

完工。
