# echo -e “ your_id ALL=(ALL) NOPASSWD: ALL' > /etc/sudoers.d/020_sudo_for_meĭuring RHEL system installation, you can enable sudo for the user you create during the installation. Also, since this doesn’t involve changing groups, you won’t have to log out and back in again. This method is easier to script and automate. You can create files in /etc/sudoers.d that will be part of the sudo configuration. %wheel ALL=(ALL) NOPASSWD: ALL Alternate method: Create a new file in /etc/sudoers.d # Allows people in group wheel to run all commands When you are done, it should look like this: Uncomment that line and comment out the wheel line without NOPASSWD. The default /etc/sudoers file contains two lines for group wheel the NOPASSWD: line is commented out. The advantage of using visudo is that it will validate the changes to the file. Edit /etc/sudoersĪs root, run visudo to edit /etc/sudoers and make the following changes. The first is more straightforward, but the latter is easier to script and automate. You can either edit /etc/sudoers or you can create a new file in /etc/sudoers.d/. To set this up, two different methods are shown. However, for developers running a RHEL VM on their laptop, this is a reasonable thing to do since access to their laptops is probably already protected by a password. For many situations (such as for real servers) this would be considered too much of a security risk. You can also configure sudo to not ask for a password to verify your identity. Note: there is no comment symbol ( #) in front of that line.Īfter logging out and back in again, you can verify that you are in group wheel by running the id command: That line enables all users in group wheel to run any command with sudo, but users will be asked to prove their identity with their password. This works because the default /etc/sudoers file on RHEL contains the following line: For the next five minutes, sudo will remember that you’ve been authenticated, so you won’t be asked for your password again. You will be asked to enter the password for your user ID when you run a sudo command. Now you will be able to use sudo when logged in under your normal user ID. To enable sudo for your user ID on RHEL, add your user ID to the wheel group: Why sudo seems to work out of the box for some users and not others.How to enable sudo during system installation.Configuring sudo to not ask for your password.How to configure sudo access on Red Hat Enterprise Linux (RHEL) and CentOS so you won’t need to use su and keep entering the root password.However when you try it, you get told your user ID is “not in the sudoers file, this incident will be reported.” For developers, sudo can be very useful for running steps that require root access in build scripts. You’ve probably seen tutorials that use sudo for running administrative commands as root.
