How to Initial server setup on Ubuntu 22.04

In the continuation of this article, we will teach you How to Initial server setup on Ubuntu 22.04. To get started, the first step is to be able to login as root using the following command. Note that after entering the following command you need to enter your root password to log in. You will also change the root password the first time you log in to the server with a password.

For Initial server setup on Ubuntu 22.04, follow the steps below to the end of the article.

How to Create a New User

After you have successfully logged in by running the above command, you now need to create a new user using the following command:

adduser michael

After running the above command, you can enter your password and then press Enter.

How to Grant Administrative Privileges

Once you’ve been able to create a new user, you now need to setup what is known as a superuser or root privilege for a regular user account to get more user privileges.

Note: Note that after this you can type sudo before the commands and execute them with superuser privileges.

usermod -aG sudo michael

How to Setup a Firewall

In this section, we are going to teach you how to setup a firewall. You should note that once installed, applications can register their profiles in the UFW. These profiles allow the UFW to manage these applications by name.

You can check the list of installed UFW profiles by running the following command:

ufw app list

Then you need to allow SSH connections in the next step. To do this, run the following command:

ufw allow OpenSSH

Now it’s time to enable the firewall using the following command:

ufw enable

After runing the following command, type “y” and then press Enter.

If you want to check the status of SSH connections, you can use the following command:

ufw status

How to Enable External Access for User

In this section we are going to enable External Access for the new user we created. The important thing to know is that configuring SSH access for your new user depends on whether your server root account uses a password or SSH keys.

As mentioned, there are two ways to access SSH, the first is to use a password and the second is to authenticate using SSH keys. In the first method, if you log in to your main account using a password, you should know that password authentication is enabled for SSH. So you can SSH to your new account using the following command:

ssh [email protected]_server_ip

If you want to run commands with administrative privileges, you can use the following command:

sudo command_to_run

In the second method, you should note that if you have logged in to your main account using SSH keys, password authentication for SSH is disabled. So to log in as your regular user with an SSH key, you need to add a copy of your local public key to the file below, which is for the new user.


You can use the following command to copy files such as the public key contained in the ~/.ssh /authorized_keys file to a root account with the correct ownership and permissions:

rsync --archive --chown=michael:michael ~/.ssh /home/michael

After you have completed all the above steps, you can now open a new terminal session on your local device and use SSH with your new username, as in the following command:

ssh [email protected]_server_ip

Note: You can enter your desired username instead of “michael” in the instructions of this tutorial.
