Another free webinar today – FreeRADIUS & MySQL Cluster: Scalable and Highly Available AAA Services

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 FreeRADIUS with MySQL Cluster
• customer case studies
• how to get started

More details for today’s webinar:

Tuesday, September 29, 2009

Join us for the last of our 4 part webinar series exploring the different aspects of using MySQL as the backend database for online applications. With real life experience gained working with MySQL Customers such as Facebook, Alcatel Lucent and Google, this webinar series will give you the information you need to run scalable, highly available online applications.

In this last installment we look at MySQL high availability technologies and architectures. We will explore the uses cases for implementing:

• MySQL Replication
• MySQL Cluster
• Distributed Replicated Block Device (DRBD)
• Other high-availability technologies

Also, covered will be the fundamentals of how these technologies work and how they can be combined to create a more scalable and highly available database infrastructure. Several case studies will be presented to show how these technologies have been implemented in the real world.

Whether you are already using MySQL for your online application or considering it for a new project then register today to learn how you can make best use of the world’s most popular database for online applications.

MySQL Cluster Helps Mapion to Improve its User Experience

A new case study has been published that describes how and why Mapion adopted MySQL Cluster as the real-time, mission critical database for their Mapion Mobile applications.

Mapion adopted MySQL Cluster Databse because it allows for the availability of existing applications through its ‘shared-nothing’ distributed architecture with no single point of failure, to meet Mapion’s mission-critical application requirements of 99.999% availability. This is coupled with automatic data partitioning with load balancing, which allows almost unlimited database scalability for the company. Mr. Takashi Ando comments, “Some databases supported clusters when we previously reviewed our database technology, but they were hard to operate and would have increased costs substantially. We found ourselves in a completely different situation when planning the introduction of the new system. MySQL Cluster Database had made it possible to construct a highly available system while keeping costs down.”

Mapion’s online map service enables users to search for addresses as well as gain access to navigation information such as directions for driving and public transport routes. The fee-based service for mobile users, Mapion Mobile, sends maps and directions direct to users’ mobile phones, while the Mapion BB broadband service offers more detailed maps, which smoothly and instantaneously refresh as the user navigates around the displayed map.

Free Guide released: Scalable Authentication Services with FreeRADIUS and MySQL Cluster

MySQL/Sun have releases a new white paper…

Do you want to ensure that your Authentication, Authorization and Accounting (AAA) infrastructure will scale to support your business growth?

As network use grows and services become more dynamic, limitations can occur which add administrative overhead, inhibit flexible scaling and impact the timely synchronization of data across the AAA environment.

To address these challenges, Sun has collaborated with the FreeRADIUS server team, the most widely deployed RADIUS server in the world, to integrate the carrier-grade, real-time MySQL Cluster database with the FreeRADIUS Server.

Download our free whitepaper “Delivering Scalable and Highly Available Authentication, Authorization and Accounting Services” now to better understand:

• The concepts of current data storage solutions for AAA environments and their potential limitations as network use grows
• How you can implement an infrastructure for high growth and high availability with low complexity by deploying the FreeRADIUS server and MySQL Cluster
• How the solution performs in real world AAA environments via a user case study.

MySQL Cluster 6.3.26 binaries released

The binaries for MySQL Cluster 6.3.26 have now been released and can be downloaded from http://dev.mysql.com/downloads/cluster/6.3.html

A description of all of the changes (fixes) that have gone into MySQL Cluster 6.3.26 (compared to 6.3.25) can be found in the MySQL_Cluster_6_3_26_ChangeLog.

MySQL Cluster 7.0.7 binaries released

The binaries for MySQL Cluster 7.0.7 have now been released and can be downloaded from http://dev.mysql.com/downloads/cluster/7.0.html

A description of all of the changes (fixes) that have gone into MySQL Cluster 7.0.7 (compared to 7.0.6) can be found in the MySQL Cluster 7.0.7 Change Log.

MySQL Cluster 7.0.7 source released

Update: As explained in “MySQL Cluster 7.0.7 binaries released” you can now download the compiled binaries for your particular platform. I am going to leave this entry in place as it will hopefully be useful for future releases but for 7.0.7 you should refer to that other post.

You’ll need to wait for the pre-built binaries but you can now download the source code and build it for yourself to get started. This article explains where to get it and how to build, install and test the installation.

In this example, I’ve used Ubuntu.

The first step is to download the compressed tar ball containing the source code by pointing your browser to ftp://ftp.mysql.com/pub/mysql/download/cluster_telco/mysql-5.1.35-ndb-7.0.7/mysql-cluster-gpl-7.0.7.tar.gz

Then you need to extract the code and then build and install the software:

billy@billy-laptop:~/mysql$ tar -xzf mysql-cluster-gpl-7.0.7.tar.gz
billy@billy-laptop:~/mysql$ mv mysql-cluster-gpl-7.0.7 7_0_7
billy@billy-laptop:~/mysql$ cd 7_0_7
billy@billy-laptop:~/mysql/7_0_7$ autoreconf --force --install
billy@billy-laptop:~/mysql/7_0_7$ ./configure --with-plugins=max --prefix=/usr/local/mysql
billy@billy-laptop:~/mysql/7_0_7$ make
billy@billy-laptop:~/mysql/7_0_7$ sudo make install
billy@billy-laptop:~/mysql/7_0_7$ sudo cp storage/ndb/src/kernel/ndbd /usr/local/mysql/bin
billy@billy-laptop:~/mysql/7_0_7$ sudo cp storage/ndb/src/kernel/ndbmtd /usr/local/mysql/bin
billy@billy-laptop:~/mysql/7_0_7$ sudo cp storage/ndb/src/mgmsrv/ndb_mgmd /usr/local/mysql/bin
billy@billy-laptop:~/mysql/7_0_7$ cd /usr/local/mysql/mysql-test
billy@billy-laptop:/usr/local/mysql/mysql-test$ sudo chmod 777 .
billy@billy-laptop:/usr/local/mysql/mysql-test$ sudo chmod 777 *

You can then test that the installation has been successful:

billy@billy-laptop:/usr/local/mysql/mysql-test$ ./mtr ndb_basic
