如何在Java中以root身份执行Shell命令

[英]How to execute shell commands as root in Java

原文 2013-08-02 15:19:25 9 2 java/ bash/ processbuilder

I'm working on a cross-platform installation utility written in Java. 我正在使用Java编写的跨平台安装实用程序。 I would like to be able to execute shell commands, for example "apt-get ..." on Linux. 我希望能够执行shell命令，例如在Linux上执行“ apt-get ...”。 I'm using the ProcessBuilder API for this purpose. 我为此使用ProcessBuilder API。

Unfortunately, some commands require root privileges. 不幸的是，某些命令需要root特权。 I would like to execute the following shell command as root: 我想以root身份执行以下shell命令：

bash -c apt-get install -y [some package] bash -c apt-get install -y [某些软件包]

If I try to add "sudo" before "apt-get" nothing works because there is no terminal "sudo" can get the password from. 如果我尝试在“ apt-get”之前添加“ sudo”，则不会起作用，因为没有终端“ sudo”可以从中获取密码。

What should I do in order to ask the user for a password and then execute the above mentioned shell command? 为了询问用户密码然后执行上述shell命令，我该怎么做？

A short code snippet would be very appreciated! 简短的代码片段将不胜感激！ Thanks in advance! 提前致谢！ Max 马克斯

您可以运行gksudo <your command>但这会将您的应用程序gksudo <your command>到某个UI，例如gnome，kde等。

You could write all the the root-tasks to a scriptfile and ask the user to execute it with root privileges. 您可以将所有的根任务写入脚本文件，并要求用户以root特权执行它。 I know this sounds clumsy, but its done that way by quite a lot of "enterprise level" software vendors (eg the (Java-) installer of the Oracle RDBMS at least up to 11g). 我知道这听起来很笨拙，但是它是由许多“企业级”软件供应商（例如，Oracle RDBMS的（Java）安装程序至少达到11g）完成的。
