在/etc/rc.local中添加
如果不想将脚本粘来粘去，或创建链接什么的，
则:
step1. 先修改好脚本，使其所有模块都能在任意目录启动时正常执行;
step2. 再在/etc/rc.local的末尾添加一行以绝对路径启动脚本的行;
如:
$ vim /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
. /etc/rc.d/rc.tune
/opt/pjt_test/test.pl
保存并退出;
