Apache2 configuration for SOGo and MediaWiki

From WickyWiki


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
SSLRandomSeed startup file:/dev/urandom 1024 
SSLRandomSeed connect file:/dev/urandom 1024

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:

Configuration (Raspberry Pi)

Another example of an Apache2 conf file, targeting a Rasberry 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
