PostGIS 1.5 in Postgresql 9.0 install on CentOS 5.6

I love short and consist install instructions. I know this is a MySQL blog but our good friend PostGreSQL has a great GIS library. This is what I learned upgrading our PostGIS system to GIS 1.5. Much thanks to Jeremy Tunnell for give this document it’s start.

Start with CentOS 5.6 x86_64 basic install.

Add the PostgreSQL Yum repository to your system.

 $ wget http://yum.pgrpms.org/reporpms/9.0/pgdg-centos-9.0-2.noarch.rpm
 $ rpm -i pgdg-centos-9.0-2.noarch.rpm

Another location for these is DAG. I have to tried these so your results may very.

You will need to exclude the packages CentOS provide by added two lines to the BASE and UPDATE sections of /etc/yum.repos.d/CentOS-Base.repo. They are:

exclude=postgresql*
exclude=geos*

You you are ready to install the needed packages. This includes proj version 4 and geos version 3.

 $ yum install postgresql90-contrib.x86_64
 $ yum …

MySQL Workbench on CentOS

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 the required libraries to support MySQL Workbench.

And unfortunately CentOS 5.5 is still the latest release. So an upgrade to CenOS 6 is not yet possible.

Using HandlerSocket Plugin for MySQL with PHP

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 of them are still rough and neither of them have documentation beyond their source code.  Maybe this will move things forward.

Here are the applications you need to have installed that where not installed in my last two posts.  Run this to …

Installing HandlerSocket (NoSQL plugin) into MiariaDB on CentOS 5.5.

The title says it all. If you don’t know what HandlerSocket is or why you would want to use it you need to reads Yoshinori Matsunobu’s blog post.

Lets get started.

 login as root

Make sure you have these packages installed:

 yum install git perl libtool gcc make openssl-devel gcc-c++ perl-DBI perl-DBD-MySQL.x86_64

If you haven’t already, install MariaDB and it’s source do that first and make sure it works. Look here http://askmonty.org/wiki/MariaDB:Download#Packages for the packages.

I’m using CentOS 5.5 x64 so I used:

 wget http://ftp.osuosl.org/pub/mariadb/mariadb-5.2.4/kvm-rpm-centos5-amd64/rpms/MariaDB-client-5.2.4-94.el5.x86_64.rpm

Downloading, compiling, and installing MySQL Server from source code

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 …

[CentOS] OpenVZ – container based virtualization quick guide. Part 1 of 2

This quick guide will walk you through setting up OpenVZ on CentOS. I followed these steps on CentOS release 5.5 x64 version. If you want more detail on install via different methods and/or have different flavor of CentOS and run into an issue, you can follow instructions provided by OpenVZ site. Once you are done with this guide, you will have CentOS container running for you to play with.

For my purposes, I started with very basic installation of CentOS 5.5. I have done this on existing installations of CentOS without any issues as well. Ok so let’s start with getting the OpenVZ repository added to our system. This means that we will be going down “yum” path instead of “rpm” path. This is the quickest and easiest way to get OpenVZ installed.

cd /etc/yum.repos.d
wget http://download.openvz.org/openvz.repo
rpm --import …

[Bash] Performing array intersection with Bash

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 servers, etc, etc. The problem came during the last
step. We decided to use a symlink to point to the active build out of a
number of builds that could be available on the server at any given time.
Since all of our servers should be running the exact same version of the
build, it …
