Vagrant environment to test MySQL Group Replication 0.8

Vadim Tkachenko recently released  Docker images for Group Replication (thank you for that ).

As not everybody is already using Docker or just because having multiple choices is also nice (this is an OpenSource world isn’t it ?), I decided to share a Vagrant environment that you can use to evaluate Group Replication.

This environment provides also a module that can be used to deploy GR on any other environment managed by Puppet.

The repository is available on my github account: mysqlGR-vagrant

This is a quick demo on how to use it:

Tadam ! You have a MySQL Group of 3 members ready to use !

Streamlined Percona XtraDB Cluster (or anything) testing with Consul and Vagrant

Introducing Consul

I’m always interested in what Mitchell Hashimoto and Hashicorp are up to, I typically find their projects valuable.  If you’ve heard of Vagrant, you know their work.

I recently became interested in a newer project they have called ‘Consul‘.  Consul is a bit hard to describe.  It is (in part):

  • Highly consistent metadata store (a bit like Zookeeeper)
  • A monitoring system (lightweight Nagios)
  • A service discovery system, both DNS and HTTP-based. (think of something like haproxy, but instead of tcp load balancing, it provides dns lookups with healthy services)

What this has to do with Percona XtraDB Cluster

I’ve had some more complex testing for  …

The Tools To Use

Over the past couple of years, several tools have come up to solve some of the long standing problems for developers, DBAs and operations teams. This list is no where near exhaustive and your mileage may vary.

These tools should let you get up and coding, saving your code to a central place.

I run (Mac/Windows), I need a Linux server to learn some of this cool stuff, right?

Not exactly. VirtualBox is a virtualization project for multiple platforms (Mac, Win, Linux, Solaris) that allows you to run a guest OS right from your laptop or desktop. There are repositories of images (alternative here) that you can use to get yourself going quickly, or you can provision your own.

I set up (cool open source package here) and now my team …

Building TokuMX and TokuDB for Production

Recently, we’ve seen a few people ask us about building TokuMX from scratch. While it’s best if you just use the binaries you can get from us (they have all the right optimizations, we’ve tested them, and we can interpret coredumps they generate), we recognize there are other reasons you might need to do a custom build.

Since we actually build six distinct products all using the Fractal Tree indexing® library (community and enterprise versions of TokuDB for MySQL, TokuDB for MariaDB, and TokuMX), our build process is pretty complicated, compared to software packages that might, for example, just involve one source repository and link against a few standard libraries. Our TokuMX builds involve four git repositories, three separate build stages, two different build tools, and …

Vagrant & Rubylibs

I was testing some MySQL puppet modules on my Vagrant box earlier this week and one of them required augeas.
I kept running into "Could not find a default provider for augeas", however all the appropriate augeas , augeas-lib and ruby-augeas packages were installed. I inspected the different ruby directories and the files were perfectly in /usr/lib/ruby/site_ruby/1.8 where I expected them.

With all the files seemd to be in the right place, my next option was to strace a small ruby script that included augeas, guess what that showed ..

  1. stat64("/opt/ruby/lib/ruby/site_ruby/1.8/augeas.rb", 0xbfd2af1c) = -1 ENOENT (No such file or directory)
  2. stat64("/opt/ruby/lib/ruby/site_ruby/1.8/", 0xbfd2af1c) = -1 ENOENT (No such file or directory)
  3. stat64("/opt/ruby/lib/ruby/site_ruby/1.8/i686-linux/augeas.rb", 0xbfd2af1c) = -1 ENOENT (No such file or directory)

Converting KVM to VirtualBox

I have had most of my test environment, aka puppetmasters, test mysql setups etc running in KVM for the past couple of years .. (yes I`m still using a lot of Xen in production environments, but we've also been using KVM for a while already .. it's a good mix) , Virtual box has always been the lesser loved Virtualization platform , however while playing more and more with Vagrant Up I realized I needed to convirt some boxen (e.g my PuppetMaster) to Virtualbox, and google was really no good help(most people seem to go the other way , or want to use some proprietary tools )

So I remembered VBoxManage and apparently I hade blogged about it myselve already ..
I just hate it when I search for stuff and google points right back to me

So I converted my puppetmaster's disks

  1. VBoxManage convertdd Emtpy-clone.img PuppetMasterroot.vdi
