introduction

This is a short rundown for setting up deployment for a jekyll blog using a self-hosted git repository and a vserver running nginx. Deployment is done with capistrano (version 3).

Github is probably the most common and most convenient way to host your code for your jekyll blog, but sometimes you might want to keep everything under your own control or you're just curious what barebones git does for you.

setting up the git repository

For setting up a git repository on a linux machine I used this guide. A short wrapup:

• add a git user

#!/bin/bash

# function to generate random password, on input requires an argument - lenght of password 
genpasswd() {
  local l=$1
  [ "$l" == "" ] && l=20
  tr -dc A-Za-z0-9_ < /dev/urandom | head -c ${l} | xargs
}

# MySQL default root password

# Clone rbenv into ~/.rbenv
git clone git@github.com:sstephenson/rbenv.git ~/.rbenv

# Add rbenv to your PATH
# NOTE: rbenv is *NOT* compatible with rvm, so you'll need to 
# remove rvm from your profile if it's present. (This is because
# rvm overrides the `gem` command.)
echo 'export PATH="$HOME/.rbenv/bin:$HOME/.rbenv/shims:$PATH"' >> ~/.bash_profile
exec $SHELL
