running a process as a different user from Python
提问by EEP
I am running a script as userAwith root access, from this script I want to make a popen()call and run a different process as userB.
我正在运行一个userA具有 root 访问权限的脚本，从这个脚本我想popen()打电话并运行一个不同的进程作为userB.
os.setuid() does not seem to work for this (unless I am doing this wrong?), and I would like to avoid a linux based solution such as su -userB -c <command>
os.setuid() 似乎对此不起作用（除非我做错了？），我想避免使用基于 linux 的解决方案，例如 su -userB -c <command>
Is there a pythonic way of running a process as userBwhile the script is running as userA?
userB当脚本运行时，是否有一种 pythonic 方式来运行进程userA？

The following answer has a really nice approach for this: https://stackoverflow.com/a/6037494/505154
以下答案对此有一个非常好的方法：https: //stackoverflow.com/a/6037494/505154
There is a working code example there, but the summary is to use subprocess.Popen()with a preexec_fnto set up the environment of the subprocess so that it executes as another user.
那里有一个工作代码示例，但总结是subprocess.Popen()与 apreexec_fn一起使用来设置子进程的环境，以便它作为另一个用户执行。
