Bugzilla 4.2 will be end of life in November 2015, so if you are thinking of upgrading, then you might want to take a look at Bugzilla 5.0 ( released in July )

You can follow the ‘Installation and Maintenance Guide’ at bugzilla.readthedocs.org or use a configuration template.

If Ansible is your thing, then the repository at bitbucket.org/wrightsolutions/ansible16bugzilla5 can be used to configure an Ubuntu server ( dedicated or cloud )

In ~/hosts.list for Ansible give your server a name such as ‘myubuntu’
and then clone the repository using:

hg clone ssh://hg@bitbucket.org/wrightsolutions/ansible16bugzilla5

From within the local cloned copy you should be able to see site.yml and then run the following:

ansible-playbook site.yml -i ~/hosts.list -u root -l myubuntu

A video demonstration of the automation is available as follows:
