Ubuntu Server Setup Scripts

This repository contains multiple shell scripts to help you quickly set up a new Ubuntu server with essential tools, security configurations, Python/Django environment, and Docker images.

Table of Contents

Introduction

These scripts are designed to automate the initial setup of a new Ubuntu server by installing necessary packages and performing essential configurations. Each script focuses on a specific aspect of server setup:

  1. Basic Setup – Installs commonly used utilities.
  2. Security Setup – Configures basic security settings (SSH, firewall, Fail2Ban, etc.).
  3. Python and Django Setup – Installs Python, PostgreSQL, and sets up an environment for Django applications.
  4. Docker Setup – Installs Docker and lets you choose which popular Docker images to download.

Basic Setup

The basic_setup.sh script installs a set of essential tools and utilities that are commonly needed on a fresh Ubuntu server.

Installed Tools:

  • curl, wget, build-essential, software-properties-common
  • vim (text editor)
  • git (version control)
  • tmux (terminal multiplexer)
  • fish (user-friendly shell)
  • htop (system monitor)

To run this script:

chmod +x basic_setup.sh
./basic_setup.sh

Security Setup

The security_setup.sh script focuses on configuring security-related settings for the server. It does the following:

  • Creates a new non-root user with sudo privileges.
  • Configures SSH for key-based authentication and disables password login.
  • Installs and configures UFW (firewall) and Fail2Ban to protect against brute-force attacks.

To run this script:

chmod +x security_setup.sh
./security_setup.sh

Python and Django Setup

The python_django_setup.sh script installs the necessary packages and dependencies for running Python and Django applications on your server. It installs:

  • Python 3, pip, and virtualenv.
  • PostgreSQL database and libraries required for connecting Django to PostgreSQL.
  • Nginx and Gunicorn for serving Django applications.

To run this script:

chmod +x python_django_setup.sh
./python_django_setup.sh

Docker Setup

The docker_setup.sh script installs Docker, Docker Compose, and allows you to pull popular Docker images based on your needs. After installation, you can choose from a set of common Docker images to download.

Available Docker Images:

  • PostgreSQL
  • MongoDB
  • MySQL
  • Redis
  • Nginx
  • Python
  • Node.js

To run this script:

chmod +x docker_setup.sh
./docker_setup.sh

Once the script asks, simply input the names of the images you'd like to pull, separated by spaces. For example:

Options: postgres mongo redis nginx

How to Use

  1. Clone this repository to your Ubuntu server:
git clone https://github.com/mr-fact/linux-setup.git
cd linux-setup
  1. Make sure the scripts are executable:
chmod +x *.sh
  1. Run the scripts in the order you need, depending on your setup requirements. For example, to start with the basic setup:
./basic_setup.sh
  1. Follow the instructions provided by each script. You may need to input some data (like a username) or make configuration choices along the way.
