Accessing all VM via one entry server/domain

I installed a reverse proxy to access Geonode, TileStream, Wiki

to read up a bit:
- see http://stackoverflow.com/questions/224664/difference-between-proxy-server-and-reverse-proxy-server
- see http://httpd.apache.org/docs/current/vhosts/examples.html

setting up re-routing to VMs

on cedeusgeonode machine
go to file /etc/apache2/sites-available/
sudo nano 000-default.conf
add the follwing content, and do afterwards the apprpriate setting in geosteiniger.cl domain using the DNS zone editor:


<VirtualHost *:80>
	# The ServerName directive sets the request scheme, hostname and port that
	# the server uses to identify itself. This is used when creating
	# redirection URLs. In the context of virtual hosts, the ServerName
	# specifies what hostname must appear in the request's Host: header to
	# match this virtual host. For the default virtual host (this file) this
	# value is not decisive as it is used as a last resort host regardless.
	# However, you must set it for any further virtual host explicitly.
       # ServerName www.example.com

	ServerAdmin webmaster@observatorio.cedeus.cl
       ServerName observatorio.cedeus.cl
       ServerAlias cedeusgeonode.ing.puc.cl
       ServerAlias observatorio.geosteiniger.cl
	DocumentRoot /var/www/html

	# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
	# error, crit, alert, emerg.
	# It is also possible to configure the loglevel for particular
	# modules, e.g.
	#LogLevel info ssl:warn

	ErrorLog ${APACHE_LOG_DIR}/error.log
	CustomLog ${APACHE_LOG_DIR}/access.log combined

	# For most configuration files from conf-available/, which are
	# enabled or disabled at a global level, it is possible to
	# include a line for only one particular virtual host. For example the
	# following line enables the CGI configuration for this host only
	# after it has been globally disabled with "a2disconf".
	#Include conf-available/serve-cgi-bin.conf

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

enabling other webpages aside GeoNode on a machine

on the machine that has geonode installed...
on Ubuntu 12.04 open sudo nano /etc/apache2/sites-evailable/geonode

(usually this would be file default, or so, but in this case geonode is already installed)
below the entry Alias /robots.txt /var/www/geonode/robots.txtadd the entry: Alias /other/ /var/www/html/

Note, the /var/www/html/ folder does not exist on Ubuntu 12.04 in contrast to Ubunutu 14.04 where it exist already
restart apache sudo service apache2 restart
for testing one may copy the default index.html file into the new /var/www/html/ folder
test with opening http://localhost/other/

ToDo

startup VMs automatically : see http://askubuntu.com/questions/404665/how-to-start-virtual-box-machines-automatically-when-booting

=> I tried to set this up, see CEDEUS Server Setup , but got some mayor crash. In this case the grub loader of CedeusDB was damaged... however, maybe it was just co-incidence?
install Elgg for use by researchers (as forum, blog, etc)
- requires installing an email client too, so I can send out messages
install CartoDB
check how to synchronize user and passwords (LDAP?)
test GeoNode 2.x on 14.04
documentation
contracts
add data
add maps
