This article will explain in detail how to configure sudo commands under Linux to run without entering a password. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

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.

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

Run sudo without a password
