Bash setup script for Ubuntu servers

This is a setup script to automate the setup and provisioning of Ubuntu servers. It does the following:

Update/Upgrade the system
Set up the hostname
Adds or updates a user account with sudo access
Adds a public ssh key for the new user account
Disables password authentication to the server
Deny root login to the server
Setup Uncomplicated Firewall
Create Swap file based on machine's installed memory
Set up the timezone for the server (Default to "Asia/Singapore")
Install Network Time Protocol
Set up nginx
Set up PHP (multiple or one version)
Set up lets encrypt
Set uo composer

This repository is a fork of ubuntu-server-setup from Jason Hee. I flavored it with a few things I need normally on every new server.

Installation

SSH into your server and install git if it is not installed:

sudo apt-get install git

Clone this repository into your home directory:

cd ~
git clone https://github.com/basteyy/ubuntu-server-setup.git

Run the setup script

cd ubuntu-server-setup
bash setup.sh

Setup prompts

When the setup script is run, you will be prompted to enter the username of the new user account.

Following that, you will then be prompted to add a public ssh key (which should be from your local machine) for the new account. To generate an ssh key from your local machine:

ssh-keygen -t ed25519 -a 200 -C "user@server" -f ~/.ssh/user_server_ed25519
cat ~/.ssh/user_server_ed25519.pub

Finally, you will be prompted to specify a timezone for the server. It will be set to 'Asia/Singapore' if you do not specify a value.

Supported versions

This setup script has been tested against Ubuntu 14.04, Ubuntu 16.04, Ubuntu 18.04, Ubuntu 20.04 and Ubuntu 22.04.

Running tests

Tests are run against a set of Vagrant VMs. To run the tests, run the following in the project's directory:
./tests/tests.sh
