linux – 如何在Ubuntu Precise上的X11之前的启动时加载环境变量?

前端之家收集整理的这篇文章主要介绍了linux – 如何在Ubuntu Precise上的X11之前的启动时加载环境变量?前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
使用Ubuntu Precise 64位,我遇到了一个我无法解决的问题,我将尝试在下面进行描述:

我正在使用一个使用Go,NodeJS,Java和Scala的控制台模式程序(比方说abc).

为了让abc使用这些语言,我要声明以下语句:

a)在/ etc / environment中:

PATH =在/usr/local / sbin中:在/usr/local / bin目录:/usr/sbin目录:在/usr/bin中:/ sbin目录:/ bin中:在/ usr /本地/去/ BIN”
CLASSPATH = $CLASSPATH:/usr/share/java/scala-library.jar

b)在/etc/login.defs中

ENV_SUPATH PATH = /usr/local / sbin:/usr/local / bin:/usr/sbin:/usr/bin:/ sbin:/ bin:/usr/local / go / bin

ENV_PATH PATH = /usr/local / sbin:/usr/local / bin:/usr/sbin:/usr/bin:/ sbin:/ bin:/usr/local / go / bin

c)a)在/ etc / sudoers中:

`#env_reset

默认值为secure_path =“/usr/local / sbin:/usr/local / bin:/usr/sbin:/usr/bin:/ sbin:/ bin:/usr/local / go / bin”

然后,当我从终端启动abc时,一切都很好,我可以使用上述4种语言中的任何一种.

但是,如果我在/etc/init.d中放置了一个在启动过程中启动abc的脚本(即在启动GUI之前),使用abc中的Java仍然可以,但使用Go,NodeJS或Scala不再起作用了.

然后,我想在启动过程中,在/ etc / sudoers,/ etc / environment和/etc/login.defs中设置的不同环境变量被加载之前,执行启动abc的/etc/init.d中的脚本.

所以,我的问题是:如何在启动我的脚本启动abc之前强制加载环境变量?

任何有关此主题的帮助和建议都将受到全面的赞赏.

TIA.
干杯.

再次感谢Mark和Danila.

下面是我在/etc/init.d中放入的Danila修改后的“abc”脚本文件

#!/bin/sh

现在,当执行此脚本(即.dodo service abc start)时,我收到以下错误消息:

fnux@fx8150-1204-3:~$sudo service abc start
/etc/init.d/abc: 4: /etc/init.d/abc: ENV_SUPATH PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin: not found
/etc/init.d/abc: 5: /etc/init.d/abc: ENV_PATH PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin: not found
/etc/init.d/abc: 6: /etc/init.d/abc: Defaults secure_path=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin: not found
/etc/init.d/abc: 7: export: ENV_SUPATH PATH: bad variable name 
fnux@fx8150-1204-3:~$

那么,我哪里错了?

TIA解释如何修复此脚本.
