To complete this guide, you must have access to your server a root or non-root user with sudo privileges. For this purpose, you can visit this guide on Initial Server Setup with AlmaLinux 9.
For detailed information to create a new user with sudo privileges, you can follow the steps below.

At this point, you can create a new user on your server by using the adduser command. For example, we create a new user named orca:
This command automatically creates a home directory for the user named /home/orca. If you want to specify your desired home directory, you must use the -d flag and define your desired path:
useradd orca -d /path/to/home
Step 2 – Add the User to a Specific Group on AlmaLinux 9
You can add your users to your desired groups on AlmaLinux 9. Here we want to add our user to the sudo groups that can have root privileges and run sudo commands.
In AlmaLinux 9, the sudoers group is named wheel. To add the user to the sudoers group, you can use the command below:
usermod -aG wheel orca
This will allow our user orca to run the root privileged commands. To verify it, you can use the following lid command:
You can easily use this command to add your users in the different groups.
Step 3 – Set a Password for the User on AlmaLinux 9
By default, the users you have created, don’t have passwords. You can give a password for them so they can log in to the server by using their own password. To do this, you can use the passwd command. Here we gave our user Orca a password with the command below on AlmaLinux:
You will be asked to enter a new password and verify it.
Changing password for user orca.
Retype new password:
passwd: all authentication tokens updated successfully.
Also, you can check your user ID and groups with the command below:
uid=1000(orca) gid=1000(orca) groups=1000(orca),10(wheel)
Step 4 – Remove Users on AlmaLinux 9
If you plan to remove or delete a specific user from your AlmaLinux 9, you can easily use the userdel command.
For example, to delete the orca user, we run the command below:
This will not remove the home directory of the user. If you want to delete the home directory too, you must use the -r flag in your command. To do this, run the command below:
userdel -r orca
That’s it, you done. These are the basic steps to adding and deleting users on AlmaLinux 9.
