/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~~
