![]() You need to provide your own public key (such as the contents of ~/.ssh/id_rsa.pub) for the value of ssh-authorized-keys: - it has been shortened here to simplify the example. Make sure that the whole cloud-init file is copied correctly, especially the first line. For this example, create the file in the Cloud Shell not on your local machine. To add a user to a Linux VM, create a file in your current shell named cloud_init_add_user.txt and paste the following configuration. Keys are added to the ~/.ssh/authorized_keys file with this cloud-init script. SSH keys are best practice for security and usability. One of the first tasks on any new Linux VM is to add an additional user for yourself to avoid the use of root. For more information about how cloud-init works natively in Azure and the supported Linux distros, see cloud-init overview. This cloud-init script runs on first boot once the resources have been provisioned by Azure. This article shows you how to use cloud-init to add a user on a virtual machine (VM) or virtual machine scale sets (VMSS) at provisioning time in Azure. If you have any questions or suggestions, feel free to leave them in the comments.Applies to: ✔️ Linux VMs ✔️ Flexible scale sets With that, you’ve given a user sudo permissions! The commands should be mostly, if not completely functional on other distros such as Debian, Fedora, or Arch Linux. Look for the same output as mentioned before. Step 2: Toggle the Administrator switch to on.Īnd that’s it! If you want to see if it worked, log in as the user you gave administrator permissions to and try running the same command as before. Enter your password when prompted to do so. Step 1: Open up the Settings application, go to ‘Users’ and click ‘Unlock’. Giving a user sudo permissions on Ubuntu Desktop is a simple two-step process: Giving sudo access to a user on Ubuntu Desktop If you get an error about the user not being in the sudoers file, try going through the instructions again, or you can use the graphical method below. All members of the sudo group granted sudo and root-level access on Ubuntu and Debian based systems. It is time to add the wendy user account to the sudo group. Now we have added a user named wendy with a password. If everything’s set up correctly, it’ll output I am root!. Step 3 Add the new user to the sudo group. You can check if the user is part of sudo group with the following: groups usernameĪlternatively, you can log in as the other user you just gave sudo access to and run a command with sudo. There are various ways you can check if a user has sudo access. How to verify if the user has sudo access If a sudo command on Linux gets you a message that a user 'is not in the sudoers file,' you'll need to get on the 'sudoers' list. To control what a user can do with sudo, edit the sudoers file with visudo. You’ll find the username near the end of the command’s output. If you're being told a user 'is not in the sudoers file,' you can add a sudo user with the usermod command. If you don’t know the exact username, you can list the users on your system using the compgen -u command. username: This is the name of the user you want to add to the sudo group.sudo: the second sudo in the command represents the sudo group.If you exclude the a option, the user would be removed from all its groups except sudo (you don’t want that). So, this adds the specified group to the specified user, without touching the user’s existing groups. -aG: The a option means append(or add), G is for groups.usermod: The usermod command is used for modifying an existing user in Linux.Let’s go over what that command just did: Just adding the user to the sudo group takes care of everything. The above command adds the user to the sudo group, which is used to track the users who are allowed to have sudo permissions. Giving a user sudo permission from the command line is just a single command if you know the username of the user: sudo usermod -aG sudo username ![]() Giving sudo permissions from the command line Lastly, to give sudo access to another user, you must have sudo access yourself. I’m assuming any users you’re doing this for have already been created. ![]() Note: this tutorial is not about creating users in Ubuntu. The GUI method will work for the desktop version of Ubuntu, while the command line method will work for both the desktop and server versions. In this tutorial, I’ll go over the steps you need for adding a user to sudoers in Ubuntu, from both the command line and a GUI. Steps to create a new sudo user on Ubuntu. That’s good, because you need root privileges to do things like perform updates and install packages(probably wouldn’t be too nice if any user could do that).īut what about new users you created after installing Ubuntu? What if the new user also needs sudo permissions? When installing Ubuntu, you’re asked to create a user, and that user gets sudo access by default. ![]()
