![]() The user needs to provide password before but after making changes the user can restart the apache service with sudo without entering the password. The -e flags tells chpasswd that the password is already encrypted, and U6aMy0wojraho is the hash of the empty string. But if you just hit enter without typing anything, and it logins as the user test-user-0. See the below screenshot before and after enabling the password-less sudo privileges for an account. sudo useradd test-user-0 echo test-user-0:U6aMy0wojraho sudo chpasswd -e su test-user-0 The password prompt still shows unfortunately. The command syntax will be like: sudo your_command_here Update entry for your user account with NOPASSWD: option as showing below:Ĭhange username with your user account and save file.Īll done, to test run any superuser command with sudo.Follow the steps to use the visudo tool and test the sudo privileges for your user account.

Learn how to modify the sudoers configuration file to allow specific users or groups to run commands without entering a password using sudo.After completing this tutorial, you can run super user commands (allowed) without entering a password. ![]() In this tutorial, you will understand how to configure passwordless sudo account on a Linux machine. Sudo is also an effective way to log who ran which command. The basic philosophy is to give as few privileges as possible but still allow people to get their work done. Then you can assign sudo privileges to that account. Sudo (sometimes considered as short for S uper- u ser do) is a program designed to let system administrators allow some users to execute some commands as root (or another user). I dont want to break a working system while trying to preemptively solve a non-existent problem. Otherwise, at least for the time being, I think Ill let good enough alone and leave the configuration as-is. None other than the root user can reboot a Linux system but you want to provide the privilege to your team member, so they can reboot the instance on the absence of you. If anyone wants to follow up with a guess why the ubuntu user needs passwordless sudo functionality, Id love to hear it. For example, a command to reboot the server.

Here’s what’s contained in those files: sudo cat /etc/sudoers To eliminate other potential issues, I created a new VM for the project, went through the setup process again, and gave the jupyter admin user a different username than my own.
