安装Memcached 1.4.5 版本
1、将下载的文件解压到任意目录。
2、1.4.5之后版本的memcached不能作为Windows服务来运行，可以在命令行中启动memcache。以管理员身份打开cmd，然后输入如下命令：
Memcached-x86 –p 11211 –m 128 –vv
memcached启动选项如下：
3、在java中如何使用Memcache
添加jar包：
commons-pool-1.5.6.jar、
java_memcached-release_2.6.6.jar、
slf4j-api-1.6.1.jar、
4、添加辅助类MemcachedUtil.java
见下
5、import java.util.Date;
import com.danga.MemCached.MemCachedClient;
import com.danga.MemCached.SockIOPool;
public class MemcachedUtil {
/**
* memcached客户端单例
*/
private static MemCachedClient cachedClient = new MemCachedClient();
/**
* 初始化连接池
*/
static {
//获取连接池的实例
SockIOPool pool = SockIOPool.getInstance();
//服务器列表及其权重
String[] servers = {"127.0.0.1:11211"};
Integer[] weights = {3};
//设置服务器信息
pool.setServers(servers);
pool.setWeights(weights);
//设置初始连接数、最小连接数、最大连接数、最大处理时间
pool.setInitConn(10);
pool.setMinConn(10);
pool.setMaxConn(1000);
pool.setMaxIdle(1000*60*60);
//设置连接池守护线程的睡眠时间
pool.setMaintSleep(60);
//设置TCP参数，连接超时
pool.setNagle(false);
pool.setSocketTO(60);
pool.setSocketConnectTO(0);
//初始化并启动连接池
pool.initialize();
//压缩设置，超过指定大小的都压缩
// cachedClient.setCompressEnable(true);
// cachedClient.setCompressThreshold(1024*1024);
