Question

我有一段代码，我想以非root身份运行。如果程序以非root身份运行，则不需要执行任何操作。但是如果程序以root身份运行，则需要删除root权限，执行代码段，然后再次启用root权限。你如何为启用/禁用编写代码？

Answer 1

尝试os.getuid()和os.setuid()。您可以使用它们在脚本中切换用户。

Answer 2

尝试以下方法：

import os
print "user who executed the code: %d" % os.getuid()
print "current effective user: %d" % os.geteuid()
if os.getuid() == 0:
    os.seteuid(65534) # user id of the user "nobody"
    print "current effective user: %d" % os.geteuid()
    # do what you need to do with non-root privileges here, e.g. write to a file
    print >> open("/tmp/foobar.txt", "w"), "hello world"
    os.seteuid(0)
print "current effective user: %d" % os.geteuid()

以root输出方式运行：

user who executed the code: 0
current effective user: 0
current effective user: 65534
current effective user: 0

Python禁用并启用根权限
