MySQL Fabric – Faulty to Secondary
Employee +1 Vote Up -0Vote Down

MySQL Fabric is a great tool for managing a farm of MySQL servers. In the last two posts you can see how High Availability Fail over and Sharding work. When things are working right, the group lookup_servers will look something like this:
server_uuid address status mode weight

MySQL Fabric and Sharding
Employee +1 Vote Up -0Vote Down

Last time we set up a High Availability server farm with MySQL Fabric. Now it is time to set up sharding. I will be using the good old World database and sharding the City table on the ID field. There are 4,079 cities in this table and they will be split in two. So one shard, that we will call CityLow will have the records 2,000 and below and the other records at 2,001 and above will be called CityHigh. We also need a global group for setting up sharding that will be called CityGlobal.

Sadly, the first step is to remove the previous setup with mysqlfabric manage …

MySQL Fabric — Three Node High Availability Server Farm
Employee +1 Vote Up -0Vote Down

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]

Fabric First Steps, er, Threads
Employee +1 Vote Up -0Vote Down

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 …

High-Availability at MySQL Central
Employee_Team +3 Vote Up -0Vote Down

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 …
