About

This repo contains installation scripts for my personal VM. The initial scrips were a fork of Stanford startup-class settings (http://github.com/startup-class/setup) for Ununtu VM, but as of today they were modified significantly and morphed into my personal environment settings.

Installation

The procedure depends on the OS:

• Ubuntu:

cd $HOME
sudo apt-get install -y git-core
git clone https://github.com/roman-spiridonov/devops
chmod +x ./devops/setup-ubuntu.sh
./devops/setup-ubuntu.sh

• Windows (Cygwin):
  • Go to link: https://cygwin.com/install.html
  • Select packages: openssh, rsync, wget, git-core, zip+unzip
  • Install apt-cyg: https://code.google.com/p/apt-cyg/, https://github.com/transcode-open/apt-cyg

lynx -source rawgit.com/transcode-open/apt-cyg/master/apt-cyg > apt-cyg
install apt-cyg /bin

4. Set up user's home: /etc/passwd > set up user's home, group and bash. Hint: Use /cygdrive/c instead of /home/.
5. Execute ~/devops/setup-cygwin.sh to install totfiles. Note that the skeleton files reside in /etc/skel inside cygwin folder.
6. Set up $PATH env variable to not contain spaces. Use c:\progra1 ("program files") and c:\progra2 ("program files (x86)").
7. Make sure to include c:\cygwin64\bin in $PATH
8. SSH

 chmod u+rwx known_hosts # for system to store identified hosts public keys
 chmod 700 ~/.ssh # .ssh settings folder
 chmod 400 key.pem # private key

Create ~/.ssh/config folder like the following:

Host awshost
HostName 54.213.193.148
User ubuntu
IdentityFile ~/.ssh/key.pem

Finally, set up SSH on Git:

• Generate new key if necessary:

ssh-keygen -t rsa -b 4096 -C "[email protected]" # Creates a new ssh key, using the provided email as a label

• Add the key to SSH agent:

eval $(ssh-agent -s) # launch SSH agent
ssh-add ~/.ssh/cg_aws_spiridonov.pem  # add key

dotfiles

This folder contains dotfiles (.bashrc, .nanorc, .emacs.d/init.el, etc.) for Ubuntu Linux and Cygwin.

The folder structure is as follows:

• Common dotfiles (cross-OS) + Ubuntu: /dotfiles/*
• Cygwin-specific dotfiles: /dotfiles/cygwin/*

Clone and run this on a new EC2 instance running Ubuntu 12.04.2 LTS to configure your the environment as follows:

cd $HOME

if [ -d .emacs.d/ ]; then
    mv .emacs.d .emacs.d~
fi

# Global
ln -sb devops/dotfiles/.nanorc .
ln -sb devops/dotfiles/dircolors.256dark ./.dircolors
ln -sb devops/dotfiles/.gitconfig .
ln -sb devops/dotfiles/.gitignore .
ln -sf devops/dotfiles/.emacs.d .

# Use for Ubuntu VM
ln -sb devops/dotfiles/.screenrc .
ln -sb devops/dotfiles/.bash_profile .
ln -sb devops/dotfiles/.bashrc .
ln -sb devops/dotfiles/.bashrc_custom .

# Use for cygwin
ln -sb devops/dotfiles/cygwin/.bash_profile .
ln -sb devops/dotfiles/cygwin/.bashrc .
ln -sb devops/dotfiles/cygwin/.minttyrc .
ln -sb devops/dotfiles/cygwin/.inputrc .
ln -sb devops/dotfiles/cygwin/.profile .

Git notes

In .gitconfig, note that the core.excludesfile refers to ~/.gitignore. This is the *nix way of defining the home directory. If you are using these dotfiles on Win system, you may need sometimes to fix this to be the following.

*nix:

git config --global core.excludesfile '~/.gitignore'

Windows:

git config --global core.excludesfile "%USERPROFILE%\.gitignore"

Emacs

Do emacs -nw hello.js and hit C-c! to launch an interactive SSJS REPL, among many other features.

Scripts

This folder contains helpful scripts.

• colortest.sh - test color scheme after installing color packages (dircolors, solarized, etc.)
