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

127.0.0.1 drupal.kevin

So far so good. Unfortunately, all that stopped working after upgrading from Ubuntu 12.04 LTS (Precise Pangolin) to 14.04 LTS (Trusty Tahr)… Continue reading

Tutorial: Cryptswap1 errors, wonky monitor displays & how to fix things after an Ubuntu 14.04 upgrade

Last week I ran into some serious problems with my Ubuntu 12.04 after some routine updates. I wasn’t able to determine exactly what happened but it was related to one of our usual suspects, the cryptswap1 error at bootup, which announces that ‘the disk drive for /dev/mapper/cryptswap1 is not ready yet or not present‘.

I tried various things suggested in forums, including this one. Unfortunately, due to a slightly different config, this culminated in me somehow partially disabling my swap space. I happened to have a Debian Live CD lying around, so I proceeded to do a harddrive backup (mainly to rescue that morning’s downloaded emails), but that was tricky because my /home folder was encrypted. 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!

Tutorial: using an IDE-to-SATA converter to install a second hard drive

the scenario: one day you stumble upon a box containing a brand new Maxtor 6Y080L0 IDE hard drive. You vaguely recall buying this in the year 2002 but it never got used for anything. You don’t really want give it away either, as it boasts a useful 80 gigabytes…so you decide to bite the bullet and attempt to install it in your PC. The only problem is, technology has moved on. You open your case and discover that your snazzy state-of-the-art motherboard sports a dizzying amount of SATA connectors – but only one IDE connector. That would be okay except for the fact that this connector is already occupied by your CD/DVD writer. Along with trying different jumper switches and drive combinations, daisy-chaining two IDE devices to this connector just won’t work.

the solution: rather than buying a new SATA harddrive and ebaying the old one, you purchase one of those handy little SATA converters for a fraction of the price. The plan is to attach it to that pesky IDE hard drive so that you can effortlessly hook it up to the SATA connectors on the motherboard.
