Hello guys!
Today is my very first day of my challenge. I'm going to log in to my server for first time and configure all necessary settings: updating server's dependencies and setting up user's permissions.
Update
After logging in, the very first thing you have to do is make sure all dependencies are up to date. For updating in Ubuntu there are two commands:
apt update
apt upgrade
If you're getting error related to permissions, because you're not logged in as root, put sudo before each command.
Optionally, you can remove outdated packages by running command apt autoremove, which I did.
New user
Using root account on daily basis is not the best move as it is the most powerful one on the machine, especially when you want to use it from SSH. I need to create new user that will have administrative rights.
I recommend you to use password manager for keeping your login informations. My first choice for storing passwords for free is KeePass.
To create new user, I typed in:
adduser johndoe
First I entered password and repeated it, then skipped all remaining fields and confirmed them. Second step of creating user is to grant permissions.
usermod -aG sudo johndoe
That's it! For confirmation, I logged in to new account and run sudo reboot now command.
In next post I will talk about securing server by setting up firewall and disable root access from ssh. See you tomorrow!
