MySQL & Dockers...a simple set up

MySQL & Dockers... are not new concepts,  people have been moving to Dockers for some time now.  For someone who is just moving to this for development, it can have a few hurdles.

While MySQL works just fine running locally, if you are testing code across different versions of MySQL it is nice to have several versions easily available.

One option for years has been of course https://mysqlsandbox.net/ by Giuseppe Maxia.  This is a very valid solution to be able to get several instances up and test replication and etc etc.

Dockers are now also another often used scenario when it comes to testing across different versions of MySQL. The following will just go over some of the steps to get several versions installed easily. I use OSX so these examples are for OSX.

You need Docker to start and of course and …

Using dbdeployer to manage MySQL, Percona Server and MariaDB sandboxes

Some years ago, Peter Z wrote a blogpost about using MySQL Sandbox to deploy multiple server versions. Last February, Giuseppe  introduced us to its successor: dbdeployer. In this blogpost we will demonstrate how to use it. There is a lot of information in Giuseppe’s post, so head there if you want a deeper dive.

First step is to install it, which is really easy to do now since it’s developed in Go, and standalone executables are provided. You can get the latest version …

mysqld_multi: How to run multiple instances of MySQL

The need to have multiple instances of MySQL (the well-known mysqld process) running in the same server concurrently in a transparent way, instead of having them executed in separate containers/virtual machines, is not very common. Yet from time to time the Percona Support team receives a request from a customer to assist in the configuration of such an environment. MySQL provides a tool to facilitate the execution of multiple instances called mysqld_multi:

“mysqld_multi is designed to manage several mysqld processes that listen for connections on different Unix socket files and TCP/IP ports. It can start or stop servers, or report their current status.”

For tests and development purposes, …

Percona Server with TokuDB (beta): Installation, configuration

My previous post was an introduction to the TokuDB storage engine and aimed at explaining the basics of its design and how it differentiates from InnoDB/XtraDB. This post is all about motivating you to give it a try and have a look for yourself. Percona Server is not officially supporting TokuDB as of today, though the guys in the development team are working hard on this and the first GA release of Percona Server with TokuDB is looming on the horizon. However, there’s a beta version available now. For the installation tests in this post I’ve used the latest version of …

Quick test run with infobright

After reading Jonathan Levin's article about infobright I decided I had to try Infobright.

So I downloaded the 32-bit tarball. Normally I would have gone for a 64-bit build but those only came in RPM and DEB flavour.

Then I tried to run infobright community edition (ICE) in a MySQL Sandbox, but that failed as the resolveip utility failed to give an answer for localhost.


error while creating grant tables
Neither host 'daniel-thinkpad' nor 'localhost' could be looked up with
/home/dveeden/opt/mysql/4.0.7-ice/bin/resolveip
Please configure the 'hostname' command to return a correct
hostname.
If you want to solve this at a later stage, restart this script
with the --force option

Then I used docker. This went really smooth. You can …

Running Percona XtraDB Cluster in a Sandbox on Ubuntu

I wanted to do some experimentation with Percona XtraDB Cluster (Galera) and I didn't want to use virtual machines. I'm already using MySQL Sandbox for many other projects so that's the natural choice.

I've downloaded the tarball for Percona XtraDB Cluster 5.5.29 and I've extracted it to ~/opt/mysql/5.5.29-pxc.

Then I've installed 3 nodes:
make_sandbox 5.5.29-pxc -- --sandbox_port 4551 \
--sandbox_directory msb_5_5_29-pxc01 

make_sandbox 5.5.29-pxc -- --sandbox_port 4552 \
--sandbox_directory msb_5_5_29-pxc02 

make_sandbox 5.5.29-pxc -- --sandbox_port 4553 \
--sandbox_directory msb_5_5_29-pxc03 

But when I try to start a node this error happens:
130327 14:21:03 [Note] WSREP: wsrep_load(): loading provider library '/home/dvee
den/mysql/5.5.29-pxc/lib/libgalera_smm.so'

MySQL Creatively in a Sandbox by Giuseppe Maxia

Giuseppe Maxia of Continuent and long time creator of MySQL Sandbox.

Only works on Unix-like servers. Works with MySQL, Percona & MariaDB servers. MySQL server has the data directory, the port and the socket – you can’t share these.

To use it: make_sandbox foo.tar.gz. Then just do ./use.

$SANDBOX_HOME is ~/sandboxes. You can also create ~/opt/mysql/ and if you have MySQL 5.0.91 binary in that directory, you can just do “sb 5.1.91″.

Sandbox has features to start replication systems as well. You can have varying master/slave setups with varying versions as well (good idea to test from MySQL -> MariaDB master->slave for migration).

You can now also play with tungsten-sandbox, which is a great way to start playing with …

Recently in MariaDB #1

The aims of this kind of blog post is simple – I want to help keep the masses informed as to what’s happening with MariaDB, as a whole. There is a community growing, and MariaDB is a community project, not necessarily a Monty Program Ab baby (and we’re clear on this distinction: think of it like Canonical/Ubuntu). So, think of it as such that I’m sharing the good news, and summarising what’s been happening, to save you time.

MariaDB added to the Debian/Ubuntu wishlists
One of MariaDB’s goals is that it should be easily available for download. While we provide binaries and source at the MariaDB download page, we would love to see the binaries sitting in Linux distributions. So it is definitely good to see that it is on …

Using MariaDB with MySQL Sandbox

A few days back MariaDB announced their first GA release (see Released: MariaDB 5.1.42), so it is time to start testing it and there is not better way to test any MySQL version in a control environment other than MySQL Sandbox. However Sandbox relies on the fact that the tarball and tarball target directory are prefixed with mysql, which is not true with MariaDB. So here are the 2 tricks I had to use to make it work out of the box.

These steps are explained to create a single sandbox, the tips can be extrapolated to any other configuration. Also, I am trying to avoid renaming any files and/or directories as to leave the packages as close to the original as possible.
Step 1: Use A Symlink For The TarballThe make_sandbox script will then …
