MySQL Fabric — Three Node High Availability Server Farm

So how do you use MySQL Fabric to set up a Highly Available Server Farm? The last two postings in this series were on installing Fabric on a master and then setting up slaves. Now it is time to get get the Fabric Farm started.

The Fabric controller is node number 1 and the slaves are 10, 20, and 30 at IP 10.10.13.1, 10, 20, and 30 respectively. I am keeping with the last octet of the IP addresses for clarity. I am trying to recreate the Fabric Farm from this image.

On the 10, 20, and 30 systems we need to add the following to the mysld section of the my.cnf
[mysqld]
binlog-format=ROW
log-slave-updates=true
gtid-mode=on
enforce-gtid-consistency=true
master-info-repository=TABLE
relay-log-info-repository=TABLE
sync-master-info=1
report-host=192.168.0.201
report-port=3306
server-id=1

Fabric First Steps, er, Threads

I will be presenting MySQL Fabric to the Triangle MySQL User Group in Raleigh on February 11th and then I will be speaking the next day at Percona University. Part of my first talk will have a live demo. Most presenters dread live demos as anything that can go wrong usually does go wrong and in very spectacular fashion to ensure humiliation, disgrace, and well deserved scorn.

To add to the pressure is a new laptop that is so far reluctant to perform well during the first two presentations of this year. Hopefully third presentation is a charm.

So how do you start with Fabric? First, download the MySQL Utilities. I am using the 1.5.2 version (1.6 Alpha is also …

High-Availability at MySQL Central

This year’s MySQL Central at Oracle Open World was an exhilarating experience. In contrast to the previous year’s MySQL Connect events, MySQL have now got their own Central at the main Oracle Open World. In the previous years, we were always short on time and trying to get a lot of sessions into just two days was just to much. This time I could both present sessions, attend sessions by other users, and also to talk to people in the MySQL community: something that I really enjoy and also find very valuable to see where we should be heading.

This year, the “MySQL Fabric Team” representation on MySQL Central was me and Narayanan Venkateswaran, which is heading the sharding solution in MySQL Fabric. Together with the conference, we also released MySQL Fabric 1.5.2 as the GA release of MySQL Fabric 1.5 containing a few new features:

Q&A: Putting MySQL Fabric to use

Martin Arrieta and I gave an online presentation last week on “Putting MySQL Fabric To Use.” If you missed it, you can find a recording and the slides here, and the vagrant environment we used plus a transcript of the commands we ran here (be sure to check out the ‘sharding’ branch, as that’s what we used during the webinar).

Thank you all for attending and asking interesting questions. We were unable to answer all of them in the scheduled time, so here are our replies to all the questions.

What is GTID? And how does it relate to MySQL Fabric?
GTID stands for Global …

Putting MySQL Fabric to Use: July 30 webinar

The focus of the webinar is to help you get started quickly on this technology, so we’ll include very few slides (mostly just a diagram or two) and then jump straight into shared screen mode, with lots of live console and …

Managing shards of MySQL databases with MySQL Fabric

This is the fourth post in our MySQL Fabric series. In case you’re joining us now, we started with an introductory post, and then discussed High Availability (HA) using MySQL Fabric here (Part 1) and here (Part 2). Today we will talk about how MySQL Fabric can help you scale out MySQL databases with sharding.

Introduction

At the time of writing, MySQL Fabric includes support for range- and hash-based sharding. As with HA, the functionality is split between client, through a MySQL Fabric-aware connector; and server, through the mysqlfabric utility and …
