I was trying out CodeIgniter  today. I found it quite lightweight and easy to get started with. MVC was fine until I came across a strange issue. Every time I tried to connect to the database, I would end up getting the infamous "500 Internal server error". Unfortunately, even after checking through all http logs, I was not able to trace it to anything that could've gone wrong. I had apache, php, mysql installed and configured correctly. Spent about 4 hours trying out different configurations, playing around with the database names, model names, etc, just to realise later that I did not have the php-mysql driver installed! This time I was on an ubuntu machine, so I had to: apt-get install php5-mysql and then although I could see that apt-get had already restarted apache2 for me, I just thought of doing it myself as well, service apache2 restart and there it was.

I had a setup of tomcat running on port 8080 and Apache proxying for tomcat on port 80.

This post is a very trivial one, but it's just that I've found myself ignoring these things time and again. Every time I need to setup a new system for development in PHP or Drupal, I've ran into almost all of these small "issues". I would always prefer to have the working copy of the code somewhere in my home directory , and maybe have it symlinked from the directory which is set as my "Document Root" in Apache. # cd /var/www/html # ln -s ~ausmarton/Public/website/drupal-7.7 drupal Assuming, everything is set up and will work, I go ahead to access the application in my browser, just to find out that all I can get is a big "Forbidden"  message. Now, this happens because, in linux, to be able to access the contents of a directory, you should have the 'x' permission. But, unfortunately, home directories are by default set not to be accessible by anyone other than the designated user. drwx------. 37 ausmarton ausmarton  4096 Aug 25 17:08 a...
