Hi Bernhard,

I paste here my working virtual server configuration, "xxx" is my user
directory, under which plugins are stored.

If I find the time I will try to install and configure it on a fresh
14.04 VM and report the steps.


cat /etc/apache2/sites-enabled/000-default.conf
<VirtualHost *:80>

   ServerAdmin webmaster at localhost
   DocumentRoot /var/www/html

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

   # Longer timeout for WPS... default = 40
    FcgidIOTimeout 120
    FcgidInitialEnv LC_ALL "en_US.UTF-8"
    FcgidInitialEnv PYTHONIOENCODING UTF-8
    FcgidInitialEnv LANG "en_US.UTF-8"
    FcgidInitialEnv QGIS_DEBUG 1
    FcgidInitialEnv QGIS_LOG_FILE /tmp/qgis-000.log
    FcgidInitialEnv QGIS_PLUGINPATH "/home/xxx/.qgis2/python/plugins"

    # ABP: needed for QGIS plugins auth
    <IfModule mod_fcgid.c>
        RewriteEngine on
        RewriteCond %{HTTP:Authorization} .
        RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    </IfModule>

  ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
  <Directory "/usr/lib/cgi-bin">
    AllowOverride All
    Options +ExecCGI -MultiViews +FollowSymLinks
    Require all granted
  </Directory>

</VirtualHost>
