如何在Ubuntu中使用python以非root用户身份运行root用户命令

Question

我正在从事一个python项目，该项目涉及运行一些sudo命令。在项目中，我必须运行systemctl命令来获取正在运行的服务的状态。为此，我有以下代码：

cmd = "sudo service mongodb status > " + status_logs
subprocess.call(cmd, shell=True)
cmd = "grep \'" + search_tag + "\' " + status_logs
status_string = str(subprocess.check_output(cmd, shell=True))

start = status_string.index(":") + len(":")
end = status_string.index(')', start)
status = status_string[start:end]
status = status + ")"
status = status.replace(" ", "")

如果我以sudo python3 app.py的形式运行上面的代码，那么我将得到active(running)或inactive(dead)的正确响应。但是我需要在没有sudo的情况下运行代码，即python3 app.py

在这种情况下，它会不断询问终端中当前用户的密码。如何删除此项并继续。请帮忙。谢谢

@alani对OP的评论是好的，特别是我会尽可能地压制，这样你的节目中的问题就不会产生灾难性的后果。例如，如果您的程序将在组mongo_checkers下运行，则类似这样的操作将启用它只检查状态：

%mongo_checkers ALL= NOPASSWD: /usr/sbin/service mongodb status

这应该是相对无害的
