spring memcache

spring memcache

学习了memcache，这是个好东西，分享一下自己的小实例，也方便以后查找使用

一、前期准备

1)  下载memcached服务端memcached-1.2.6-win32-bin.zip，地址：http://code.jellycan.com/memcached/

2)  下载java版客户端 java_memcached-release_2.6.1.zip
3)  解压缩memcached-1.2.6-win32-bin.zip到指定目录，例如：D:\memcached-1.2.6-win32 ，在终端（即cmd命令行界面）

D:\memcached-1.2.6-win32\memcached.exe -d install
D:\memcached\memcached.exe -d start

这样memcache就会作为windows系统服务在每次开机时启动memcache服务。

常用命令

-p 监听的端口  -l 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 以的身份运行 (仅在以root运行的时候有效)  -m 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 最大同时连接数，默认是1024  -f 块大小增长因子，默认是1.25  -n 最小分配空间，key+value+flags默认是48  -h 显示帮助
