To clarify: with sudo su, you’re using more than one root setuid command in the background. Where it differs from sudo su is that sudo -i is a much cleaner way of gaining root and a root environment without directly interacting with the root user. sudo -i is also very similar to using sudo su: it’ll read all of the environmental files (“.profile”, etc.) and set the environment inside the shell. Much like sudo su, the -i flag allows a user to get a root environment without having to know the root account password. Using sudo -i is virtually the same as the sudo su command with one exception: it does not directly interact with the root user. While you could do this in the meantime, you should still reset the root password at some point. This is useful in situations where you may have forgotten the root password if it’s different from the password for your user account. Root is given with sudo su by requesting the current user’s password, which makes it possible to gain root without the root password. Though there isn’t a large divergence between sudo su and su, the former is still a very useful command for one important reason: when a user is running su to gain root access on a system, they must know the root password. If any command is run with sudo in front of it, it is given root privileges. When sudo su is run, “.profile,” “.bashrc” and “/etc/profile” will be started, much like running su (or su root). Try it on VPS hosting from Atlantic.It’s essentially the same as just running su in the shell, save for one crucial difference: instead of telling the system to “switch users” directly, you’re telling it to run the su command with superuser privileges. You can now grant superuser privileges to any regular user in your Linux environment. In this post, we explained how to create a sudo user in Rocky Linux 8. How to Use the id Command in Linux Conclusion The above output confirms that the user has sudo rights and can run administrative commands. Provide the password of user1 to run the above command. #3) With great power comes great responsibility. It usually boils down to these three things: If everything is fine, you will be asked to provide a password for user1: We trust you have received the usual lecture from the local SystemĪdministrator. Next, run any administrative command with sudo: sudo dnf update To verify, switch the user to the user1 using the following command: su - user1 Verify the Sudo UserĪfter adding a normal user to the sudo group, you will need to verify whether the newly created user has sudo rights. This command will add a user1 to the wheel group. You can use the usermod command to add a normal user to the wheel group. Next, you will need to add your created user to the sudo (wheel) group in order to grant it administrative privileges. Add a Normal User to the sudo (wheel) Group Save and close the file after the confirmation. Make sure the following line exists: %wheel ALL=(ALL) ALL Next, you will need to edit /etc/sudoers file and confirm that the wheel group is enabled. How to Change or Set User Passwords in Linux Enable Wheel Group access for All Users Passwd: all authentication tokens updated successfully. You will be asked to set a password as shown below: Changing password for user user1. Next, set a password for this user with the following command: passwd user1 Let’s create a new user named user1 with the following command: adduser user1 If you have not created any normal or no-root user on your system, then you will need to create one user. Connect to your Cloud Server via SSH and log in using the credentials highlighted at the top of the page. Create a new server, choosing Rocky Linux 8 as an operating system with at least 1GB RAM. A root password configured on your serverįirst, log in to your Atlantic.Net Cloud Server.A server running Rocky Linux 8 on the Atlantic.Net Cloud Platform.In this post, we will show you how to create a sudo user in Rocky Linux 8. In this case, you will need to add a normal user to the sudo group in order to execute administrative commands. The sudo command, short for “super-user do,” is a Linux utility that allows a normal user to run any commands with unlimited privileges. The non-root users have limited interactions with an operating system environment and they can perform only user-specific tasks. The root user has full control of the operating system and it has privileges to run administrative commands like installing, removing, and updating software packages, changing permissions, and configuring different services. In Linux or Unix-based operating system, there are two types of users: a superuser (root) and a normal or regular user.
