Apache2 configuration for SOGo and MediaWiki

Info

Here I keep the most up-to-date script for server wilbertvolkers.linkpc.net for both MediaWiki and SOGo.

• MediaWiki on http (80) and https (443). Force secure SSL login.
• SOGo only on https (443) redirect http (80) to https (443)

An entry for a Raspberry Pi has been added.

Configuration (Ubuntu)

Disable default SOGo configuration of Apache:

sudo mv /etc/apache2/conf.d/SOGo.conf /etc/apache2/conf.d/SOGo.conf.backup

Create new configuration in 'sites-available':

sudo gedit /etc/apache2/sites-available/wilbertvolkers.linkpc.net.conf

Enable Apache modules and website

Enable needed Apache2 modules:

sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod headers
sudo a2enmod rewrite
sudo a2enmod ssl
sudo service apache2 restart

Enable the site:

sudo a2ensite wilbertvolkers.linkpc.net
sudo service apache2 reload

To test if everything is working go to:

• https://wilbertvolkers.linkpc.net/SOGo
• http://wilbertvolkers.linkpc.net/SOGo
  • You should go to https
• http://wilbertvolkers.linkpc.net/mediawiki
• https://wilbertvolkers.linkpc.net/mediawiki
• http://wilbertvolkers.linkpc.net/mediawiki/index.php?title=Special:UserLogin
  • You should go to https

Configuration (Raspberry Pi)

An example of an Apache2 conf file, targeting a Raspberry Pi system but not exclusively. This configuration:

• allows only https access, http is redirected to https
• contains some additional security measures for MediaWiki
• no SSLv3, search for 'poodle attack' is you want to know more

sudo gedit /etc/apache2/sites-available/raspberrypi.conf
