将脚本保存在 /etc/init.d/目录下，如/etc/init.d/memcached
执行如下命令

chmod +x /etc/init.d/memcached
chkconfig memcached on
service memcached start

让memcached自动启动，防止系统重启后memcached失效chkconfig --add memcached然后检查一下是否设置成功。chkconfig --list memcached如果2~5写的是on的话说明设置成功。但是在一些CentOS版本中，–add命令无法成功，可以用下面的语句代替：chkconfig memcached on然后再次检查一下，一般不会有问题了，只要2~5设置为on，那么memcached就已经会随着系统自动启动了。
