ubuntu操作系统创建开机启动脚本

1.创建一个脚本

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

exit 0

2.在exit 0之前写好shell脚本
3.给脚本增加执行权限

sudo chmod +x test.sh

4.在启动目录下创建软链接

sudo ln -s test.sh /etc/init.d/

5.添加自启动

cd /etc/init.d/
sudo update-rc.d test.sh defaults 90

说明90为优先级，数字越大，启动越晚。
6.放弃开机启动

sudo update-rc.d -f test.sh remove
