Restarts FreeRADIUS when NAS entries are changed in SQL database

FreeRADIUS NAS change restarter

Yes, the name is a mouthful.

What is this?

A MySQL table definition, triggers, and a python program to track changes to the NAS table and restart FreeRADIUS after ensuring that other RADIUS servers are running (to avoid creating downtime).

Why would I use it?

• You run FreeRADIUS with a MySQL backend.
• You have a web interface to add or change NAS definitions.
• You don't want to manually restart FreeRADIUS on each server every time you change a NAS with your web interface.
• Yes, FreeRADIUS only reads the NAS table once at startup: http://lists.cistron.nl/pipermail/freeradius-users/2005-June/msg00113.html

What does it need to run?

• Python 2
• pyrad 2: http://pypi.python.org/pypi/pyrad/2.0
• MySQL for Python (python-mysqldb)

How do I use this?

• Create the NAS updates table by loading sql/table.sql into MySQL.
• Load triggers from sql/triggers.sql
• Customize reloader.json for your environment. Save reloader.json to /etc/reloader.json
• Make sure /var/lib/reloader exists and the user that will run reloader has read and write permissions to it.
• Make sure there is at least one entry in the nas_changes table as the result of a change in the nas table
• Run reloader.py from cron every 5 minutes or so.
