MySQL Workbench on CentOS
+0 Vote Up -0Vote Down

Every once in a while I use MySQL Workbench. First is was only for Windows, then it was unstable and now it is very well usable. Or at least that is the situation when you run on a recent Ubuntu machine.

I'm now using CenOS 5.5 in a VirualBox VM to do some testing. Unfortunately the download site for MySQL Workbench has RPMs for RedHat 6 and Fedora Core 14 and some other platforms. No CentOS, No RHEL5, only the latest Fedora en RHEL.

So I downloaded the RHEL6 RPMs and tried to install them with yum localinstall, but that failed. So they are not backwards compatible with 5.5.

Turns out that CentOS/RHEL 5 doesn't have …

Using HandlerSocket Plugin for MySQL with PHP
+2 Vote Up -0Vote Down

This document was updated and tested for CentOS 6.0

In my last two posts I installed the HandlerSocket plugin into MariaDB and showed how to use it with Perl.  That’s good, but if you are thinking of using HandlerSocket  I’m guessing you have a very high traffic website and it’s written in PHP.  In this post I’m going to connect HandlerSocket with PHP.  In the next post I’ll discuss using HandlerSocket on a production system.

There are a couple of HandlerSocket php modules projects.  I tried each of them and I found PHP-HandlerSocket was the best.  Both …

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 …

[Bash] Performing array intersection with Bash
+0 Vote Up -0Vote Down

I am currently working on a project to deploy new website builds to a
small number of servers. I needed something simple and reliable that could
be built in a very short period of time. I decided to whip something up in
bash with the intent of refining it in Python later.

As I began to write this code, I realized that it probably would have been
quicker to do it in Python from the start. I decided to stick with bash as
somewhat of an academic exercise. The vast majority of these deployment
scripts were trivial; check the code out of git, create a manifest, package
it up, spew it to the …

Sphinx As MySQL Storage Engine (SphinxSE)

Sphinx As MySQL Storage Engine (SphinxSE)

SphinX is a great full-text search engine for MySQL. Installing the Sphinx daemon was straightforward as you can compile it from the source or use a .DEB/.RPM package but SphinxSE was a little bit tricky since it needed to be installed as a plugin on a running MySQL server. So if you use Debian or Centos and install your MySQL from a .deb or .rpm package this is how you do it.

How to install MongoDB on CentOS 5.4 / RHEL5 and interface with PHP 5
+0 Vote Up -1Vote Down

If you’ve been reading up on the various NoSQL offerings and have wanted to try out one but don’t know how to get started, this is one of the easiest ways. I chose MongoDB for this example because I’m going to start using it for a project that needs features that MySQL isn’t as fast at: namely denormalized data with billions of rows. MongoDB has plenty of drivers for other scripting and high-level languages but I’ll focus on the PHP driver today. If there is interest I can do a write up on Python usage later. This example is limited to CentOS, Fedora, and Redhat 5 servers that use the yum package management system. For more information you can reference their …

Is MariaDB really a drop in replacement for MySQL?   I’m running CentOS 5.4.  What happens if…

  2. Go to http://askmonty.org/wiki/MariaDB:Download and download the CentOS 5 packages.
