The explanation in this article is simple and clear and easy to learn and understand. please follow Xiaobian's train of thought to study and learn "how to configure sudo commands in Linux to run without entering a password".

Suppose you run Linux on a computer that you only use, such as on a laptop, and you need to enter a password every time you call sudo, which will be boring in the long run. Therefore, in this guide, we will describe how to configure the sudo command to run without entering a password.

This setting is done in the / etc/sudoers file, which is the default security policy using the sudo command; in the user rights assignment section.

Important: in the sudeors file, the authenticate parameter turned on by default is used for verification purposes. If it is set, the user must authenticate with a password (or other authentication method) before running the command using sudo.

However, you can use the NOPASSWD (no password is required when the user invokes the sudo command) flag to override this default value.

The syntax for configuring user permissions is as follows:

User_list host_list=effective_user_list tag_list command_list

Where:

User_list-list of users or user aliases that have been set up.

Host_list-list of hosts or host aliases on which users can run sudo.

Effective_user_list-list of users running under that user or alias

Tag_list-list of tags, such as NOPASSWD.

Command_list-A list of commands or command aliases that the user runs using sudo.

To allow users (aaronkilik in the following example) to run all commands without entering a password using sudo, open the sudoers file:

$sudo visudo

Add the following line:

Aaronkilik ALL= (ALL) NOPASSWD: ALL

For groups, use% characters before the group name; this means that all members of the sys group can use sudo without a password.

% sys ALL= (ALL) NOPASSWD: ALL

To allow the user to run the specified command (/ bin/kill) without a password using sudo, add the following line:

Aaronkilik ALL= (ALL) NOPASSWD: / bin/kill

The following line allows members of the sys group not to enter a password when running the command: / bin/kill, / bin/rm using sudo:

% sys ALL= (ALL) NOPASSWD: / bin/kill, / bin/rm
