设置服务:

chmod +x /opt/demo_name/demo_name.sh
/bin/ln -sf /opt/demo_name/demo_name.sh /etc/init.d/demo_name


# debian|ubuntu
which update-rc.d && update-rc.d demo_name defaults

# centos
which chkconfig && chkconfig demo_name on



常见错误:service XXX does not support chkconfig

在脚本的开头#!/bin/sh后面添加下面两行即可

#chkconfig: - 85 15
