====== apache2 + dokuwiki + ssl + letsencrypt (certbot) + virtual hosts (2020) ======

  * Install stuff

  apt-get install letsencrypt python3-certbot-apache dokuwiki apache2

  * Configure ssl for main webpage

  a2ensite 000-default-le-ssl.conf
  sudo certbot --apache -d www.memelabs.net --post-hook "/usr/sbin/service apache2 restart"

  * Create ssl for dokuwiki webpage:
    * Copy 000-default-le-ssl.conf to dokuwiki-ssl.conf. Edit DocumentRoot to point to /usr/share/dokuwiki
    * Create ssl certificate for dokuwiki:

  sudo certbot --apache -d wiki.memelabs.net --post-hook "/usr/sbin/service apache2 restart"

  * Redirect non-ssl (port 80) webpages to ssl ones:
  * Edit 000-default.conf, add:

  Redirect permanent / https://www.memelabs.net

  * Do the same with the dokuwiki weppage. Create dokuwiki_ssl.conf:

  <VirtualHost *:80>
  ServerName wiki.memelabs.net
  DocumentRoot /usr/share/dokuwiki
  Redirect permanent / https://wiki.memelabs.net
  RewriteEngine on
  RewriteCond %{SERVER_NAME} =wiki.memelabs.net
