Memcached windows 下安装与测试

Memcached 是一个高性能的分布式内存对象缓存系统，用于动态Web应用以减轻数据库负载。它通过在内存中缓存数据和对象来减少读取数据库的次数，从而提供动态、数据库驱动网站的速度。Memcached基于一个存储键/值对的hashmap。其守护进程（daemon ）是用C写的，但是客户端可以用任何语言来编写，并通过memcached协议与守护进程通信。但是它并不提供冗余（例如，复制其hashmap条目）；当某个服务器S停止运行或崩溃了，所有存放在S上的键/值对都将丢失。

下载Windows的Server端

下载地址：http://code.jellycan.com/memcached/

安装Memcache Server(也可以不安装直接启动)

1. 下载memcached的windows稳定版，解压放某个盘下面，比如在c:\memcached
2. 在CMD下输入 "c:\memcached\memcached.exe -d install" 安装.
3. 再输入："c:\memcached\memcached.exe -d start" 启动。NOTE: 以后memcached将作为windows的一个服务每次开机时自动启动。这样服务器端已经安装完毕了。

如果下载的是二进制的版本，直接运行就可以了，可以加上参数来加以设置。

常用设置：
-p <num>          监听的端口
-l <ip_addr>      连接的IP地址, 默认是本机
-d start          启动memcached服务
-d restart        重起memcached服务
-d stop|shutdown  关闭正在运行的memcached服务
-d install        安装memcached服务
-d uninstall      卸载memcached服务
-u <username>     以<username>的身份运行 (仅在以root运行的时候有效)
-m <num>          最大内存使用，单位MB。默认64MB
-M                内存耗尽时返回错误，而不是删除项
-c <num>          最大同时连接数，默认是1024
-f <factor>       块大小增长因子，默认是1.25
-n <bytes>        最小分配空间，key+value+flags默认是48
-h                显示帮助

然后就可以用.net 的memcached客户端来试一下了。
