Python禁用並啓用Root權限

Question

我有一段代碼，我想以非root用戶身份運行。如果程序以非root用戶身份運行，則不需要發生任何事情。但是，如果程序以root身份運行，則需要刪除root權限，執行代碼段，然後再次啓用root權限。你如何編寫啓用/禁用代碼？

Answer 1

嘗試以下操作：

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() 

運行此爲根輸出：

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

嘗試os.getuid()和os.setuid()。您可以使用它們在腳本中切換用戶。
