MySQL End Of Life (EOL) Policy

We’ve discussed today how we should implement MySQL Version advisory in mk-audit tool. One obvious questions was to look at the end of life – it is often bad idea to run MySQL versions past end of life as even security bugs may not be fixed in these (though do not get paranoid, if you’re […]

Should we proclaim MySQL Community Edition Dead ?

We were chatting with Jeremy Cole today and he brought to my attention last version of MySQL Community Eddition (5.0.51) was released in November 2007 – over 7 months ago. MySQL 5.0.51a and MySQL 5.0.51b security fixes were released but these can’t be considered proper releases. If we look at the old Kaj’s Announcement we […]

MySQL Performance Blog now uses Sphinx for Site Search

I never liked how build in WordPress search works. it shows full documents rather than snippets it does not search comments and it does not have any query language so I always used Google search if I wanted to find something on MySQL Performance Blog. Today we have published new search functionality for our site […]

CentOS Comes with free build of MySQL Enterprise ?

As I already wrote you can well go to Linux distribution vendors if you’re looking for recent MySQL version in a hassle free binary form. (On the time of this writing you could only get binaries for MySQL Community 5.0.45 from MySQL Download Pages which was released in July and so about half a year […]

MySQL Master-Master replication manager released

The MySQL Master-Master replication (often in active-passive mode) is popular pattern used by many companies using MySQL for scale out. Most of the companies would have some internal scripts to handle things as automatic fallback and slave cloning but no Open Source solution was made available. Few months ago we were asked to implement such […]

MySQL sources from development tree

First of all you need a fresh free client – bk-client2.0 http://www.bitkeeper.com/Hosted.Downloading.html . Once you get it, you can clone latest tree: bkf clone bk://mysql.bkbits.net/mysql-5.0 mysql-5.0 New client supports “changes” command, so you can look […]

Heartbleed: Separating FAQ From FUD

If you’ve been following this blog (my colleague, David Busby, posted about it yesterday) or any tech news outlet in the past few days, you’ve probably seen some mention of the “Heartbleed” vulnerability in certain versions of the OpenSSL library. So what is ‘Heartbleed’, really? In short, Heartbleed is an information-leak issue. An attacker can […]

Percona XtraDB Cluster: Setting up a simple cluster

Percona XtraDB Cluster (PXC) is different enough from async replication that it can be a bit of a puzzle how to do things the Galera way.  This post will attempt to illustrate the basics of setting up 2 node PXC cluster from scratch. Requirements Two servers (could be VMs) that can talk to each other. […]

Getting Percona PAM to work with Percona Server & its client apps

Percona Server is bundled with the PAM plugin which opens a plethora of ways to authenticate to MySQL such as restricting time when users can connect to MySQL, authenticate via a USB key, authenticate to an external authentication system such as LDAP and many, many more PAM compatible mechanisms. If you want to use PAM […]

Your troubles are over, pt-heartbeat 2.1

Poor pt-heartbeat 2.1: it was perfectly fine through Percona Toolkit 2.1.7, but it’s had a rough life since. Its troubles are finally over as of Percona Toolkit 2.1.10. At a conference recently, a user joked to me that “Percona Toolkit is awesome, but you really broke pt-heartbeat.” It’s true, and if you haven’t heard or […]
