Introduction
When you buy a vps or dedicated server with Ubuntu 18.04 server installed, there are a few steps that you should take. Those steps will increase the security and usability of your server and keep away the attackers.
Note: The guide Initial Server Setup for Ubuntu 18.04 demonstrates how to manually complete the steps we recommend for new Ubuntu 18.04 servers. Following this procedure manually can be useful to learn some basic system administration skills and as an exercise to fully understand the actions being taken on your server.
Step 1 — Logging in as Root
In order to log in to your server, you need to know the public IP address of the server. You will also need the password or if you installed an SSH key for authentication, the private key for the root user’s account.
If you are not already connected to your server, go ahead and log in as the root user using the following command (substitute the highlighted portion of the command with your server’s public IP address):
ssh root@your_server_ip
Accept the warning about host authenticity if it appears.
About Root
The root user is the administrative user in a Linux environment that has very broad privileges. Because of the heightened privileges of the root account, you are discouraged from using it on a regular basis. This is because part of the power inherent with the root account is the ability to make very destructive changes, even by accident.
The next step is to set up an alternative user account with a reduced scope of influence for day-to-day work. We’ll teach you how to gain increased privileges during the times when you need them.
