通过修改Linux服务自动启动指定应用程序(涉及运行级别)
转自：http://www.cnblogs.com/interboy/archive/2008/07/25/1251745.html

Linux中修改系统服务的命令是chkconfig (check config)，命令的详细解释如下:
start)
/usr/Tomcat/bin/startup.sh
touch /var/lock/subsys/tomcat
;;
status)
if [ -f /var/lock/subsys/tomcat ]; then
echo $"tomcat is running"
exit 0
fi
echo $"tomcat has stopped"
exit 3
;;
stop)
/usr/Tomcat/bin/shutdown.sh
rm -f /var/lock/subsys/tomcat
;;
restart)
/usr/Tomcat/bin/shutdown.sh
/usr/Tomcat/bin/startup.sh
;;
*)
echo "Usage: tomcat {start|stop|restart|status}"
exit 1
esac
exit 0
