Server Setup

1. Description

This git repository contains scripts for setting up remote servers. It contains both bash scripts to build packages from source, as well as docker files to build docker images.

2. Folders

docker/: this folder contains Dockerfiles and Docker Compose (docker-compose.yml) files for multi-container builds.
dpkg/: this folder contains build scripts where dependencies are installed via apt. Mostly for builds on Debian (and possibly also Ubuntu)
yum/: this folder contains build scripts where dependencies are installed via yum. Mostly for builds on Amazon Linux.
scripts/: this folder contains build scripts that do not involve package managers such as apt, yum, or apk.

3. Quick setup for a new server

3.1 SSH Keys

ssh-keygen -t rsa -b 4096 -f ~/.ssh/id_rsa -q -N ""

cd ~/.ssh/
KEY_NAME="keypair-use1"; KEY_FILE="keypair-use1.pem"; REGION="us-east-1"
ssh-keygen -t rsa -b 4096 -f ~/.ssh/$KEY_FILE -q -N ""
aws ec2 import-key-pair --key-name ${KEY_NAME} --public-key-material fileb://${KEY_FILE}.pub --region ${REGION}

3.2 Shell

3.2.1 Bash

Customize ~/.bashrc as follows:

cat >> ~/.bashrc << EOF
export PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
export SUDO_PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
HISTSIZE=50000
HISTFILESIZE=50000
TERM='xterm-256color'
alias ls='ls --color=auto'
alias grep='grep --color=auto'
EOF
source ~/.bashrc

3.2.2 Zsh + Starship

Check current shell

echo $SHELL

Change shell to Zsh using:

chsh -s /bin/zsh

Install Starship as follows:

curl -sS https://starship.rs/install.sh | sh

Customize ~/.zshrc as follows:

cat >> ~/.zshrc << EOF
export PS1="%F{green}%n@%m%f %F{red}%W%f %F{yellow}%1~%f %# "
export SUDO_PS1="%F{green}%n@%m%f %F{red}%W%f %F{yellow}%1~%f %# "
export HISTFILE=~/.zsh_history
export HISTSIZE=20000
export SAVEHIST=\$HISTSIZE
eval "\$(starship init zsh)"
EOF

3.2.3 Instance Metadata

GIT_USERNAME=$(git --no-pager show -s --format='%an' HEAD)
GIT_USEREMAIL=$(git --no-pager show -s --format='%ae' HEAD)
git config --local user.name "$GIT_USERNAME"
git config --local user.email "$GIT_USEREMAIL"
