#!/bin/bash
#
# How to use
# ----------
# 
# This file automates the installation of hubzilla under Debian Linux
#
# 1) Copy the file "hubzilla-config.txt.template" to "hubzilla-config.txt"
#       Follow the instuctions there
# 
# 2) Switch to user "root" by typing "su -"
# 
# 3) Run with "./hubzilla-setup.sh"
#       If this fails check if you can execute the script.
#       - To make it executable type "chmod +x hubzilla-setup.sh"
#       - or run "bash hubzilla-setup.sh"
# 
# 
# What does this script do basically?
# -----------------------------------
# 
# This file automates the installation of hubzilla under Debian Linux
# - install
#        * apache webserer, 
#        * php,  
#        * mysql - the database for hubzilla,  
#        * phpmyadmin,  
#        * git to download and update hubzilla itself
# - download hubzilla core and addons
# - configure cron
#        * "poller.php" for regular background prozesses of hubzilla
#        * to_do "apt-get update" and "apt-get dist-upgrade" to keep linux
#          up-to-date
#        * to_do backup hubzillas database and files (rsnapshot)
# - configure dynamic ip with cron
# - to_do letsencrypt
# - to_do redirection to https
# 
# 
# Discussion
# ----------
# 
# Security - password  is the same for mysql-server, phpmyadmin and hubzilla db
# - The script runs into installation errors for phpmyadmin if it uses
#   different passwords. For the sake of simplicity one singel password.
# 
# Security - suhosin for PHP
# - The script does not install suhosin.
# - Is the security package suhosin usefull or not usefull?
#
# Hubzilla - email verification
# - The script switches off email verification off in all htconfig.tpl.
#   Example: /var/www/html/view/en/htconfig.tpl
# - Is this a silly idea or not?
#
# 
# Remove Hubzilla (for a fresh start using the script)
# ----------------------------------------------------
#
# You could use /var/www/hubzilla-remove.sh
# that is created by hubzilla-setup.sh.
#
# The script will remove (almost everything) what was installed by the script.
# After the removal you could run the script again to have a fresh install
# of all applications including hubzilla and its database.
# 
# How to restore from backup
# --------------------------
#
# Daily backup
# - - - - - - 
# 
# The installation
# - writes a script /var/www/hubzilla-daily.sh
# - creates a daily cron that runs the hubzilla-daily.sh
#
# hubzilla-daily.sh makes a (daily) backup of all relevant files
# - /var/lib/mysql/ > hubzilla database
# - /var/www/html/ > hubzilla from github
# - /var/www/letsencrypt/ > certificates
# 
# hubzilla-daily.sh writes the backup
# - either to an external disk compatible to LUKS+ext4 (see hubzilla-config.txt)
# - or to /var/cache/rsnapshot in case the external disk is not plugged in
# 
# Restore backup
# - - - - - - - 
# 
# This was not tested yet.
# Bacically you can copy the files from the backup to the server.
# 
# Credits
# -------
#
# The script is based on Thomas Willinghams script "debian-setup.sh"
# which he used to install the red#matrix.
#
# The script uses another script from https://github.com/lukas2511/letsencrypt.sh
#
# The documentation for bash is here
