Memcached入门

Memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

一）Memcached服务器
从http://www.splinedancer.com/memcached-win32/下载安装文件并解压到c:\memcached；在Windows命令行控制台(cmd)界面上，进入cd c:\memcached目录下。可执行以下操作：
# 安装
memcached -d install
# 启动
memcached -d start
# 停止
memcached -d stop


二）Memcached客户端
从https://github.com/gwhalin/Memcached-Java-Client/tree/master/src下载Jar包(选择Download)，添加Jar到项目中。可写如下的简单测试程序：

import com.danga.MemCached.MemCachedClient;
import com.danga.MemCached.SockIOPool;

public class BasicTest {
	protected static MemCachedClient mcc  = new MemCachedClient();
	static {	
		String[] servers = { "127.0.0.1:11211" };		
		Integer[] weights = { 3 };
		SockIOPool pool = SockIOPool.getInstance();	
		pool.setServers(servers);
		pool.setWeights(weights);
		pool.setInitConn(5);
		pool.setMinConn(5);
		pool.setMaxConn(250);
		pool.setMaxIdle(1000 * 60 * 60 * 6);	
		pool.setMaintSleep(30);
		pool.setNagle(false);
		pool.setSocketTO(3000);
		pool.setSocketConnectTO(0);
		pool.initialize();
	}

	public static void main(String[] args) throws Exception {
		mcc.set("foo", "Hello, world!");
		Object bar = mcc.get("foo");
		System.out.println(bar);	
	}
}

三）Memcached更多的资料
Memcached在Google上的网址：http://code.google.com/p/memcached/
Memcached的官方网址：http://memcached.org/
上面的服务器是搭建在Windows平台上，客户端使用的是Memcached-Java-Client提供的Jar包。其他平台、语言（各种语言有多个实现库）的Memcached实现及其详细的使用方法，在上面两个网址中可以找到丰富的参考资料（比如Wiki, FAQ等）。
