memcache配置实践

一、下载安装memcache服务器

/Files/dlz1123/memcacheddotnet_clientlib-1.1.5.zip，

解压，然后在cmd命令行安装c:

cd \解压后文件所在目录

memcached.exe -d install

memcached.exe -d start        该命令启动 Memcached，默认监听端口为 11211

 

参数解释：

-d 以守护程序（daemon）方式运行 memcached；

-m 设置 memcached 可以使用的内存大小，单位为 M；

-l 设置监听的 IP 地址，如果是本机的话，通常可以不设置此参数；

-p 设置监听的端口，默认为 11211，所以也可以不设置此参数；

-u 指定用户，如果当前为 root 的话，需要使用此参数指定用户。

 

-h 帮助 

二、安装客户端 

/Files/dlz1123/memcacheddotnet_clientlib-1.1.5.zip

解压之后将文件中的Memcached.ClientLibrary.dll 添加到项目的引用中

代码

  public   void  clear()
        {
         string [] servers  =  {  " 10.10.80.94:11211 "  };
            SockIOPool pool  =  SockIOPool.GetInstance();
            pool.SetServers(servers);
            pool.InitConnections  =   3 ;
            pool.MinConnections  =   3 ;
            pool.MaxConnections  =   5 ;
            pool.SocketConnectTimeout  =   1000 ;
            pool.SocketTimeout  =   3000 ;
            pool.MaintenanceSleep  =   30 ;
            pool.Failover  =   true ;
            pool.Nagle  =   false ;
            pool.Initialize();
            MemcachedClient mc  =   new  Memcached.ClientLibrary.MemcachedClient();
            mc.EnableCompression  =   false ;
            mc.Delete( " cache " );
            Response.Write( " 清除缓存成功 " );
        }


         public   void   get ()
        {
             string [] servers  =  {  " 10.10.80.94:11211 " };
            SockIOPool pool  =  SockIOPool.GetInstance();
            pool.SetServers(servers);
            pool.InitConnections  =   3 ;
            pool.MinConnections  =   3 ;
            pool.MaxConnections  =   5 ;
            pool.SocketConnectTimeout  =   1000 ;
            pool.SocketTimeout  =   3000 ;
            pool.MaintenanceSleep  =   30 ;
            pool.Failover  =   true ;
            pool.Nagle  =   false ;
            pool.Initialize();
            MemcachedClient mc  =   new  Memcached.ClientLibrary.MemcachedClient();
            mc.EnableCompression  =   false ;
            StringBuilder sb  =   new  StringBuilder();
             // 写入缓存
            sb.AppendLine( " 写入测试： " );
            sb.AppendLine( " <br>_______________________________________<br> " );
             if  (mc.KeyExists( " cache " ))
            {
                sb.AppendLine( " 缓存cache已存在 " );
            }
             else
            {
                mc.Set( " cache " ,  " 写入缓存时间： "   + DateTime.Now.ToString());
                sb.AppendLine( " 缓存已成功写入到cache " );
            }
            sb.AppendLine( " <br>_______________________________________<br> " );
            sb.AppendLine( " 读取缓存内容如下：<br> " );
            sb.AppendLine(mc.Get( " cache " ).ToString());


             // 分析缓存状态
            Hashtable ht  =  mc.Stats();
            sb.AppendLine( " <br>_______________________________________<br> " );
            sb.AppendLine( " Memcached Stats: " );
            sb.AppendLine( " <br>_______________________________________<br> " );
             foreach  (DictionaryEntry de  in  ht)
            {
                Hashtable info  =  (Hashtable)de.Value;
                 foreach  (DictionaryEntry de2  in  info)
                {
                    sb.AppendLine(de2.Key.ToString()  +   " :&nbsp;&nbsp;&nbsp;&nbsp; "   +  de2.Value.ToString()  +   " <br> " );
                }
            }
            Response.Write(sb.ToString());
        }
