It’s interesting to see how all of these entities blog about technology, and there is more and more interest shown by managerial technologists about the database. This Log Buffer Edition appeases their appetites along with the others in [...]

Got open source cloud storage? Red Hat buys Gluster
+0 Vote Up -0Vote Down

Red Hat’s $136m acquisition of open source storage vendor Gluster marks Red Hat’s biggest buy since JBoss and starts the fourth quarter with a very intersting deal. The acquisition is definitely good for Red Hat since it bolsters its Cloud Forms IaaS and OpenShift PaaS technology and strategy with storage, which is often the starting point for enterprise and service provider cloud computing deployments. The acquisition also gives Red Hat another weapon in its fight against VMware, Microsoft and others, including OpenStack, of which Gluster is a member (more on that further down). The deal is also good for Gluster given the sizeable price Red Hat is paying for the provider of open source, software-based, scale-out storage for unstructured data and also as validation of both open source and software in

Open Query looking for new colleagues!
+1 Vote Up -1Vote Down
My colleagues and I are looking for extra talent – is that you? What we do:help clients prevent problems (rather than being the fire department), we work on a subscription basis although we also do some ad-hoc consulting, and training. Apart from MySQL/MariaDB query and DBA work, we do quite a bit of system administration. Mainly Red Hat and Debian based distros, and expect to see replication and the MySQL-MMM multi-master system. You’d work from home, whereever it might be, so you will need to be self-motivating (but we do keep in touch online). What we’re not: a full-time employer. With us, you make a life rather than a living. Everybody is contracted part-time. You can make enough to live comfortably, but that has nothing to do with hours. If you’re stressed about not filling all hours in your week with work-work-work, we’re not  [Read more...]

Just follow our very simple installation instructions.

Downloading, compiling, and installing MySQL Server from source code
+0 Vote Up -0Vote Down

This content has been updated and moved to a new place.


If you are running any GNU/Linux server operating system like RHEL 5 or CentOS 5, you may probably install MySQL server that comes with the operating system packages either during the initial setup or later using yum(8). The advantage being addition/removal of packages either using the GUI package manager or rpm(8), yum(8). Fair enough. But unfortunately the MySQL package (mysql-server) that comes bundled with RHEL 5.5 or CentOS 5.5 is fairly old (5.0.77). What if you want to install the latest stable version of MySQL yet have the advantage of removing/re-installing the software using rpm(8)?


In this blog post, I will guide you with compiling MySQL from source code yet installing the software through rpm(8) so that we tune and

MySQL in RHEL5/CentOS5 gets an update
+1 Vote Up -0Vote Down

It’s worth noting that Red Hat Enterprise Linux (RHEL) 5 has had an update to MySQL in the last month. This naturally means that CentOS 5 also had a similar update. It’s now bumped up to MySQL 5.0.77 (goodbye 5.0.45!; which is what RHEL5 shipped with). This is a moderate security release, so consider updating, if you can afford a mysqld restart.

Read more about the 4 CVE bugs fixed. CentOS followed suit within two weeks.

Red Hat’s organic growth opportunities

We reported recently on Red Hat’s revenue growth and deferred revenue. One of the things I have been looking at recently is the slowdown in Red Hat’s growth in recent years, and the opportunities that the company has to improve that growth.

For some perspective it is worth noting that while Red Hat’s revenue has been growing steadily:

The rate of growth has been in decline for some time:

MySQL: How do you enable sphinxse (Sphinx Storage Engine) in your mysql installation?
+0 Vote Up -0Vote Down

As you may know mysql fulltext search is not highly scalable.  One of the options to get around this scalability limitation, which I prefer, is to use Sphinx.  You can use Sphinx with out having to alter your mysql installation.  But, if you would like to use from within mysql and not have to worry about how to pass data between Sphinx and MySQL, you can enable sphinxse (sphinx storage engine).  It is not included with mysql by default so you will have to compile it yourself.

Here are the instructions on how to get sphinxse compiled with your mysql installation on CentOS x64.  I am sure same instructions will work for other flavors but I have not tested it.  I will be compiling the most current version of sphinx (0.9.8) with most current stable version of mysql (5.0.51b) at the time of the writing.  Let’s get the

Maatkit in RHEL and CentOS
+0 Vote Up -0Vote Down

Update: Karanbir says “Just one thing to keep in mind is that we dont want too many people using it from the Testing repository - we only need enough feedback to move it from testing to stable ( and to be honest, there are already 8 people who have said yes it works - so move to stable should happen within the next 24 - 48 hrs ). Once the package is in stable, users on CentOS4 and 5 wont need to do anything more than just ‘yum install maatkit’ and it will install for them.”

At least one person (Karanbir Singh) is working to get Maatkit into the CentOS repositories, and I believe there might be movement towards RHEL also. From an email to the Maatkit discussion list a little while ago,
