Memcached开机启动方式
　　方法一：
　　在 /etc/rc.d/rc.local 文件中追加启动命令
　　/usr/local/memcached/bin/memcached  -u root -d -m 2048 -l 192.168.137.99 -p 11211 -P /tmp/memcached.pid
　　也可不指定IP，默认是本机，如
　　/usr/local/memcached/bin/memcached  -u deamon -d -m 2048 -p 11211 -P /tmp/memcached.pid
　　用户好是 apache 或 deamon
　　方法二：
　　#写服务脚本
　　vim /etc/init.d/memcached
　　粘贴如下代码
#!/bin/sh
#
# memcached:    MemCached Daemon
#
# chkconfig:    - 90 25
# description:  MemCached Daemon
#
# Source function library.

#[ ${NETWORKING} = "no" ] && exit 0
#[ -r /etc/sysconfig/dund ] || exit 0
#. /etc/sysconfig/dund
#[ -z "$DUNDARGS" ] && exit 0
