In the past I made a script for automating svn updates. Since sourceforge has been making a habit of crashing lately, I decided to start using the git repo instead and adjusted my script to work with git.
I figured others might benefit from it so why not share…
#!/bin/bash
clear
# -------------------------------------------
# Fog Git Updater
# -------------------------------------------
# -------------------------------------------
# Script Purpose
# -------------------------------------------
# This script is designed to run an automated update of the latest FOG Git dev build and it's cron friendly
# -------------------------------------------
# -------------------------------------------
# Some prereqs for this script
# -------------------------------------------
# 1. Already have an existing working install/configuration of FOG 1.0 or later
#
# 2. Have git installed and setup. You can do that by doing....
# sudo apt-get install git
# mkdir /home/fog/fogInstalls/git
# git clone https://github.com/FOGProject/fogproject.git /home/fog/fogInstalls/git
#
# 3. A script to echo the encrypted version of your sudo password, create one with this function
# just put in your password into the following in place of your_super_secret_password (leave the quotes)
# and then uncomment and copy paste the function into a terminal and then run it with just the name of the function pw
# pw(){
# touch /home/fog/fogInstalls/.~
# ossl=`echo "your_super_secret_password" | openssl enc -des -a -e -pass pass:PASSWORD`
# echo 'echo "$(echo '$ossl' | openssl enc -des -a -d -pass pass:PASSWORD)"' >> /home/fog/fogInstalls/.~
# sudo chown fog.root /home/fog/fogInstalls/.~
# sudo chmod 700 /home/fog/fogInstalls/.~
# }
# -------------------------------------------
# -------------------------------------------
# Variables
# -------------------------------------------
# -------------------------------------------

srvUpdate(){
# Enter sudo mode aand do some quick server maintenance update fun times
# First, enter sudo mode by echoing the output of decrypting your encrypted password and pipe that into an apt-get update
# Don't worry, it doesn't output the password into the terminal
# Now that the password is in once the terminal will keep it stored for the next bunch of sudo commands
echo "Running Sever updates!..."
echo $pw | sudo -S apt-get update -y
sudo apt-get upgrade -y # install any upgrades you just downloaded
}
backupConfig(){
# Backup custom config and other files
# Copy the latest versions of any files you've changed that will be overwritten by the update and backup the database just in case.
# For example you may want to back up...
# Config.php
# To be on the safe side your config file in the /opt folder that has may have a corrected webroot for ubuntu 14.04 and may have stored encrypted credentials (i.e mysql)
# I think that the installer uses this file and keeps it anyway, but I like to be careful
# Exports file
# Because this runs the installer with a yes pipe, it ends up telling it that the image path is "y",
# simply backing up and restoring your current one avoids the issue of fog not finding your precious images.
# Custom pxe boot background
# If you have a custom background for the pxe menu, the bg.png file
# Mysql database dump
# It would be rather troublesome if something went horribly wrong in the update and your database goes kaboom, it's unlikely but backups are a good thing
# Just a note, It's a good policy to also have backups of these outside of your server, which you could add to this script with an scp command or something like that
