SysAdmin with Me: Initial Server Setup Ubuntu 24.04 LTS

System Administration on Linux

Initial Server Setup. Ubuntu 24.04 LTS

Watch as we set up a brand new DigitalOcean Droplet and prepare it for further software installation. Steps performed: Add a user, give the user 'sudo' privileges, configure UFW firewall.

All the configuration steps are taken directly from DigitalOcean's tutorials. When making your own server, feel free to change any of the steps or to make this process individualized for your needs. The tutorial will stick directly with the article just for consistency!

First, create your server.

Then, log in:

ssh root@your_server_ip

Create a user.

adduser sammy

Grant privileges by adding your user to the 'sudo' group.

usermod -aG sudo sammy

Set up a firewall. First, list the UFW profiles

ufw app list

Allow the OpenSSH profile.

ufw allow OpenSSH

Enable UFW.

ufw enable

View UFW status.

ufw status

Sync SSH key used to provision the server with the newly created user.

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

SSH with the new user account.

ssh sammy@your_server_ip

Of course make sure to substitute your own user name if you aren't named 'sammy'.
