MediaWiki/Sphinx : setup a full text indexer

12 August 2013 in Debian, Hi-Tech, Linux, Web

You certainly know and have used the default MediaWiki search. It’s quite good but it’s not an optimal search. I wanted to have better one for my wiki that’s why I added Google search some years ago. I didn’t want to setup Apache Lucene or Apache Solar as both are in Java. I always heard good feedback about Sphinx, that’s why I decided to add it at work and to my wiki as well.

PackStack : quickly deploy OpenStack for production

8 August 2013 in Debian, Hi-Tech, Linux, OpenStack, Puppet, Red Hat

Last week, I’ve assisted to a webinar organized by Puppet Labs. The talk was about PackStack which is a solution to deploy OpenStack in a production environment. How does PackStack works ? Some of you may tell me that DevStack do the same thing. But I warn once again about DevStack which is absolutely not build for production usages ! PackStack is a bundle of current modules for OpenStack available on Puppet Forge.

PuPHPet : speed up your Vagrant deployment

6 August 2013 in Databases, Debian, Hi-Tech, Linux, Mac, Puppet, Red Hat, SQL, Virtualization, Web

Vagrant is a fast solution build on top of VirtualBox. I already talked about it in a previous post. The thing is, you could do really more with Vagrant by adding Puppet manifests or Chef recipes in your Vagrant configuration file. For those who don’t often use one of those 2 softwares, it quickly could transform into a nightmare when they want to deploy softwares in addition of the OS.

Do you want to try my desktop configuration ?

4 August 2013 in Debian, Developement, Hi-Tech, Linux, Others, Private life

Some of you already told me how complicated the setup of my software configurations could be. Depending on which configuration you’re talking about, it may be more or less complicated to install in the good folders, launching the good commands etc… In addition, sometimes I need to set up a quick desktop environment with my preferences and deploy all I need may take a while. That’s why I’ve written some scripts (in Python and shell script) to help on deploying all my configuration and all the packages I wish.

LXC : Debian reported issue still not fixed

2 August 2013 in Debian, Hi-Tech, Linux

Hi everyone ! As you know I recently started to play with LXC :-) At the beginning of my tests, I unfortunately found an annoying bug which avoid performing correct Debian installation over LVM. I tried to resolve it by myself but didn’t had enough time to finish my investigation. After quick searches, I found that other people found the bug on github : https://github.com/simonvanderveldt/lxc-debian-wheezy-template/issues/1#issuecomment-21303483 As a rule, I searched it on Debian bugs list but nothing was reported.

Galera Cluster : How to do maintenance and recover

29 July 2013 in Hi-Tech, Linux, SQL

To finish my Galera’s posts, I’ve wrote tips to help on maintenance and recover for the Galera Cluster (in french). As most of the time, Galera is able to manage automatically data recovering, some times (if split brain occurs for example) you need to manually do specific stuffs to recover the cluster. I hope this will help some of you if problems occurs.

Galera Cluster : choose the better SST method

25 July 2013 in Hi-Tech, Linux, SQL

Last month, I’ve wrote a document accessible on slideshare to explain some of basic/advanced features of MySQL/MariaDB. In addition, there were some informations related to Galera Cluster running on top of MariaDB. I’ve updated my documentation to help on choosing the better SST method and understand the differences (in french).
