如何在python子流程中由其他用户运行文件

你可以尝试下面的解决方案

def change(user_uid, user_gid):
    def result():
        report_ids('starting demotion')
        os.setgid(user_gid)
        os.setuid(user_uid)
        report_ids('finished demotion')
    return result

def report_ids(msg):
    print 'uid, gid = %d, %d; %s' % (os.getuid(), os.getgid(), msg)


import subprocess
filename = '/mount/test.sh'
#mention UID and GID here
p = subprocess.Popen(filename, preexec_fn=change(1000, 1000))
result = p.wait()
print(result)

注意:我用check_输出代替popen。因为我不能测试,如果有打字或错误,请原谅。另外,检查p.communicate是否与check_输出一起工作。
