One-click initialize Ubuntu instance

Overview

init.sh is used to initialize many kinds of Ubuntu 20 instances including WSL, vagrant, or server instances(AWS EC3, Vultr.com server, etc). It installs necessary dependencies and applications.

By default, the scripts won't set up my personal configurations and private keys unless the environment variable EVA is set.

Usage

[EVA=] ./init.sh <command>

For instance, if I create a new server from any cloud service provider, all I need to do is to run

./init.sh server

and enter the password if needed, then I'm all set.

If I want to install docker on the machine, I'll do

./init.sh docker

If I want to set up the /etc/sudoers file so that I won't need to enter the passwd to run sudo, I'll do

./init.sh config_sudo

However, if I want to set default shell to zsh and import my configuration for oh-my-zsh and spacemacs, I'll do

EVA= ./init.sh config_terminal

All <command> are defined by the scripts within src folder and are declared within the type of bash functions.

Type of instance

• server - AWS EC2 instance or other ubuntu server. Install basic.
• sa_server - Servers that I didn't have sudo permission.
• wsl - reinstall openssh-server and set up ssh listening port on port 2233.
• vagrant - similar to how server is set up. Set up ssh listening port on port 2233.

App name to be installed

• basic - install all development environments and necessary terminal utils, including zsh, build-essential, python, etc.
• docker - follows the official document to install docker

Configurations

Note that only config_sudo runs without the environment variable $EVA set since they all import my personal configurations

• config_sudo - make sudo not need to enter password
• config_git - add git configuration and add github.com to authorized_keys
• config_terminal - configure zsh, emacs, and clone this repo to ~/.eva
• config_vim - add vim configuration and download dependencies
• config_server - add id_rsa.pub to authorized_keys
• config_wsl - set up wsl according to WSL-CLion
