Initial setup script for Ubuntu

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

• Change default repository to Tsinghua Ubuntu Mirror
• Setup the timezone for the server
• Update and upgrade the packages on Ubuntu
• Install some basic packages

Installation

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

sudo apt-get update
sudo apt-get install git

Clone this repository into your home directory:

cd ~
git clone https://github.com/pspdada/ubuntu-initializer.git

Run the setup script

cd ubuntu-initializer
./setup.sh

Different Line Endings

Windows/MS-DOS text files use a pair of characters, carriage return (CR or \r) and line feed (LF or \n), as their line endings, whereas Unix text files use only the line feed (LF) character. Therefore, for files created on a Windows system that have been copied to a Linux system for some reason, the format needs to be converted. You can use the following command:

dos2unix ./setup.sh

Supported versions
