/home/memcached/bin/memcached -d -m 1024 -p 11211 -u root

参数说明: -d 启动为守护进程 -m 分配给Memcached使用的内存数量,单位是MB,默认为64MB -u 运行Memcached的用户,仅当作为root运行时 -l 监听的服务器IP地址,默认为环境变量INDRR_ANY的值 -p 设置Memcached监听的端口,最好是1024以上的端口 -c 设置最大并发连接数,默认为1024 -P 设置保存Memcached的pid文件,与-d选择同时使用

完成~~~以上仅为试验,如果只是一个小web单机环境的话,只需要php+eaccelerator(或者apc/xcache等)就足够了。用php+memcached+mysql-proxy+mysql是大型网站架构的事情~~
