Memcached Tip 1:使用Memcached Providers

Memcached的Windows版本在这里下载http://code.google.com/p/memcached/wiki/PlatformWindows(或http://memcachedproviders.codeplex.com/),最高的版本是1.4.4,但是已经很难在网上下载到。不过http://www.couchbase.com/对Memcached进行了很好的维护,但是这个团队把Memcached封装进了自己的产品中(1.4.4也是由这个团队开发的,但是它们已经移除了1.4.4的Memcached的独立分支)。我没有试过couchbase的产品,故本例针对1.2.6(你也可以从本站下载memcached.rar,反正只有几十K)。

1:将Memcached注册进Windows服务

memcached -d install

2:启动Memcached服务

memcached -d start

3:停止和移除Memcached服务

memcached -d stop

memcached -d uninstall

4:查看Memcached状态

使用

telnet localhost 11211
然后,输入stats,如果有如下结果就表示安装成功了:

5:Memcached客户端

Memcached的.NET客户端,比较著名的就是http://memcachedproviders.codeplex.com/,它其实封装的是enyim.com Memcached Client。选取Memcached Providers 1.2 .NET 3.5。

6:一个简单的示例

创建一个Winform,引用客户端包中的3个DLL,为其设定App.config,如下:

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="cacheProvider" type="MemcachedProviders.Cache.CacheProviderSection,  MemcachedProviders" allowDefinition="MachineToApplication" restartOnExternalChanges="true"/>
    <sectionGroup name="enyim.com">
      <section name="memcached" type="Enyim.Caching.Configuration.MemcachedClientSection, Enyim.Caching"/>
    </sectionGroup>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
  </configSections>
  <log4net>
    <!-- Define some output appenders -->
    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] 
- %message%newline"/>
      </layout>
    </appender>
    <!--<threshold value="OFF" />-->
    <!-- Setup the root category, add the appenders and set the default priority -->
    <root>
      <priority value="WARN"/>
      <appender-ref ref="ConsoleAppender">
        <filter type="log4net.Filter.LevelRangeFilter">
          <levelMin value="WARN"/>
          <levelMax value="FATAL"/>
        </filter>
      </appender-ref>
    </root>
  </log4net>
  <enyim.com>
    <memcached>
      <servers>
        <!-- put your own server(s) here-->
        <add address="127.0.0.1" port="11211"/>
      </servers>
      <socketPool minPoolSize="10" maxPoolSize="100" connectionTimeout="00:00:10" deadTimeout="00:02:00"/>
    </memcached>
  </enyim.com>
  <cacheProvider defaultProvider="MemcachedCacheProvider">
    <providers>
      <add name="MemcachedCacheProvider" type="MemcachedProviders.Cache.MemcachedCacheProvider, MemcachedProviders" keySuffix="_MySuffix_" defaultExpireTime="2000"/>
    </providers>
  </cacheProvider>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup></configuration>

同时,我们的主程序如下:

        private void buttonSet_Click(object sender, EventArgs e)
        {
            DistCache.Add(this.textBoxKey.Text, this.textBoxValue.Text);
            this.textBoxKey.BackColor = Color.White;
            this.textBoxValue.BackColor = Color.White;
            MessageBox.Show("设置成功");
        }

        private void buttonGet_Click(object sender, EventArgs e)
        {
            object obj = DistCache.Get(this.textBoxKey.Text);
            if (obj != null)
            {
                this.textBoxValue.Text = obj.ToString();
                this.textBoxKey.BackColor = Color.Gray;
                this.textBoxValue.BackColor = Color.Gray;
            }
            else
            {
                this.textBoxValue.Text = "没有这个Key值";
                this.textBoxKey.BackColor = Color.Gray;
                this.textBoxValue.BackColor = Color.Gray;
            }
        }

注意using MemcachedProviders.Cache;

我们也可以很容易将此程序应用到Asp.net中。
