This document describes how to setup a FreeRADIUS server. A MySQL server is used as backend and for the user accounting.

RADIUS is an industry-standard protocol for providing authentication, authorization, and accounting services.

• Authentication is the process of verifying a user’s identity and associating additional information (attributes) to the user’s login session.
• Authorization is the process of determining whether the user is allowed on the network and controlling network access values based on a defined security policy.
• Accounting is the process of generating log files that record session statistics used for billing, system diagnosis, and usage planning.

MySQL Cluster is a popular backend for FreeRADIUS, as it provides a scalable backend to store user and accounting data. However, there are situations when the backend database becomes a centralized datastore for additional applications and services, and needs to take a more general-purpose role. NDB usually works very well for FreeRADIUS data, but for wider use cases and reporting type applications, InnoDB can be a better storage engine. For users who need to keep their data in InnoDB and still benefit from a highly available clustered datastore, Galera Cluster can be an appropriate alternative.

In this post, we will show you how to deploy FreeRadius both with MySQL Cluster and Galera Cluster to store user and accounting data. All servers are running CentOS 6.4 64bit.

FreeRadius Deployment with Galera

We will deploy a two-node FreeRadius cluster …

As network use grows and services become more dynamic, so existing Authentication, Authorization and Accounting (AAA) environments can struggle to keep pace with demand.

Tune into this webinar where you can hear from the Alan Dekok, one of the founders of the FreeRADIUS project and CEO of Network RADIUS, discuss the concepts and implementation of RADIUS services using the FreeRADIUS server and the MySQL Cluster database to deliver highly available and scalable AAA services.

As always, this webinar is free and you can register here. I will be manning the Q&A during the webinar.

In this session, you will learn about:

• potential AAA limitations as network environments grow
• advantages of deploying FreeRADIUS with MySQL Cluster
• Performance, sizing and deployment of an AAA environment using …

Scalable, Highly Available RADIUS solution using FreeRADIUS and MySQL Cluster

Before a client can start to access and consume services on a network, they must first be Authenticated to the network and then Authorized to use the services they are entitled too.  Their consumption of network resources then needs to be captured via the Accounting processes.  Collectively, Authentication, Authorization and Accounting (AAA) is a cornerstone of today’s network security, management and in many cases, monetization. RADIUS is a standard protocol to implement this AAA service.

As these networks grow, limitations can occur which add administrative overhead, inhibit flexible scaling and impact the timely synchronization of data across the AAA environment.

Using MySQL Cluster as the data store for a RADIUS server makes …
