Starting the Installation
To get going, you simply need to issue the following command:
sudo apt-get install bugzilla3
This will grab Bugzilla and all the packages required to make Bugzilla work. If you have never installed MySQL before, the first dialog you will be greeted with is the one shown below. This is the step to set the "root" password for MySQL. Just make sure you pick a secure password and don't forget it! When you are done, click "Forward" to move on to the next step.
The next dialog window you will see is the one shown below. This dialog is simply asking if you would like help configuring your database, so just click "Forward" to move on to configuring Bugzilla.
For this step you will need the password for your MySQL database server. More specifically, you need the password for the administrative user "root" (this is the password you entered in the first step) so that the installation program can install the default databases for you .
The next step is to enter a password for the Bugzilla program to use. This is simply the password that is used by Bugzilla to interact with the MySQL database. If you don't want to make up a password for this step, you can just hit "Forward" and the installer will generate a password for you and store it in /etc/bugzilla3/localconf.
A Few Extra Tweaks
Now that you have the base install out of the way, you need to tweak a few files to get everything working. The first step is to copy the example Bugzilla configuration file to the Apache configuration folder. This can be done with the following command:
sudo cp /usr/share/bugzilla3/debian/apache.conf /etc/apache2/conf.d/bugzilla3.conf
This will setup Apache to point to the correct directories and libraries for Bugzilla. Once the file has been copied, restart Apache by issuing the following command:
sudo /etc/init.d/apache2 restart
The final step is to make sure that the Bugzilla parameter file is readable by Apache. This can be done with the following commands:
chmod g+rw /etc/bugzilla3/params
chown www-data:www-data /etc/bugzilla3/params
If all goes well you should be able to browse to your server (http://your_server_name/cgi-bin/bugzilla3) and see the Bugzilla login page. Now you are ready to login and get to smashing bugs!
If It Doesn't Work
If you follow all of these steps and Bugzilla still isn't working, your best option is to watch the Apache error log while you attempt to connect to the Bugzilla main page. You can do this by using the tail command to watch the log:
tail -f /var/log/apache2/error.log
