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/
