我已经在 Azure 中创建了 Ubuntu 20.04 的实例,并且我注意到我可以运行 sudo 命令而无需输入密码。
我假设这是通过使用文件NOPASSWD
中的指令来完成的/etc/sudoers
,但该文件是完全标准的并且不包含该指令。
有人可以告诉是否还有其他方法可以实现这一目标吗?
/etc/sudoers 文件:
#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.

Defaults env_reset
Defaults mail_badpass
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
