Installation

Apache/mod_wsgi/mysql

First, make sure you have the following software installed:

On ubuntu, sudo apt-get install apache2 libapache2-mod-wsgi python-virtualenv mysql-server should suffice.

To create the database and user homunculus will use, enter the following in a mysql-shell:

CREATE DATABASE homunculus;
GRANT ALL PRIVILEGES ON *.* TO 'homunculus'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;

Then, choose a directory where you want to install homunculus. In this example, we assume /var/www/homunculus

$ mkdir -p /var/www/homunculus
$ mkdir -p /var/www/homunculus/data
$ mkdir -p /var/www/homunculus/data/webserver/apache
$ cd /var/www/homunculus

To install the dependencies in a virtualenv and create a runner, run this:

$ virtualenv --no-site-packages pythonenv
$ pythonenv/bin/pip install homunculus_server mysql-python

Copy the file examples/runner.wsgi into /var/www/homunculus, and edit it, so that it fits your needs.

Add the following lines to your apache config:

Include /var/www/homunculus/data/webserver/apache

<VirtualHost *>
        ServerName homunculus.example.com
        WSGIScriptAlias / /var/www/homunculus/runner.wsgi
</VirtualHost>

Homunculus needs privileges to restart the webserver, via sudo /etc/init.d/apache2 reload. To grant these privileges, on ubuntu/debian edit your sudoers file, and append the following:

www-data   ALL = NOPASSWD: /etc/init.d/apache2

Make sure, all files beneath /var/www/homunculus are writeable by the webserver. Assuming the webserver’s user is www-data, you can achieve that by this command:

sudo chown www-data:www-data -R /var/www/homunculus

Restart apache. The command is something like /etc/init.d/apache2 reload, reload apache2 or simimlar, and depends on your OS.

With a webbrowser, visit http://homunculus.example.com/migrations/ and click “Execute all”

Go to http://homunculus.example.com. Homunculus should now be running.
