就是使用 apt-get、apt-fast 安装软件就会报错,安装失败!

编写了一个tomcat开机自启动脚本,执行没问题,但是在安装mysql的时候出现了大量的:

居然还导致mysql安装后的自动配置提示失败,按照LSB tags规范改写脚本如下(debian8环境):

其实解决办法就是在#!/bin/bash下面添加:

### BEGIN INIT INFO
# Provides:          bbzhh.com
# Required-Start:    $local_fs $network
# Required-Stop:     $local_fs
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: tomcat service
# Description:       tomcat service daemon
### END INIT INFO

当然,也可以一劳永逸的:

apt-get remove insserv

启动脚本文件就放在 /etc/init.d/ 文件夹下,文件名就叫报错的服务名。我报的是 tomcat8 ,是按别人教程安装的 tomcat ,看来就算是按着教程来,也不一定就没错误。
(PS:我还是建议不要走所谓的一劳永逸,还是改上面的文件比较稳妥。反正我是按上面的成功了,一劳永逸的方法不成功,反而出了另外的一些问题。)
