Tutorial: reconfiguring virtual hosts after upgrading to Apache 2.4.7 on Ubuntu – what you need to change


Once upon a time, I was running Apache 2.2.22. I had set up my virtual hosts by making up some fantasy domain names for each of my sites, such as drupal.kevin. I would then edit /etc/apache2/vhosts.conf to add information about my DocumentRoot, DirectoryIndex and CustomLog for each of my sites. Because I wanted to make sure they were always backed up properly, I kept my websites in my /home folder rather than /var/www/html, which meant I also needed a symlink from there to my websites directory. Lastly, I would add a line for every virtual host in /etc/hosts, such as drupal.kevin

Though I am told it is possible, I didn’t have the time on top of all this to go & read up on how this could be done via a Live CD!
