This is a setup script to automate the setup and provisioning of Ubuntu servers. It does the following: * Adds a new 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 * Setup the timezone for the server (Default to "Asia/Singapore") * Install Network Time Protocol
SSH into your server and install git if it is not installed:
bash sudo apt-get update sudo apt-get install git
Clone this repository into your home directory:
bash cd ~ git clone https://github.com/jasonheecs/ubuntu-server-setup.git
Run the setup script
bash cd ubuntu-server-setup bash setup.sh
When the setup script is run, you will be prompted to enter the username and password 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:
bash ssh-keygen -t rsa cat ~/.ssh/id_rsa.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.
This setup script has been tested against Ubuntu 14.04, Ubuntu 16.04, Ubuntu 18.04 and Ubuntu 20.04.
Tests are run against a set of Vagrant VMs. To run the tests, run the following in the project's directory:
