Ansible: Neo4j role available on Ansible Galaxy

27 February 2015 in Ansible, Databases, Debian, Hi-Tech, Linux, NoSQL, SQL

For a new project (will talk about it later), I needed to use Neo4J (graph database if you don’t know it yet). I tried to cover more features than the current existing Ansible roles available on Ansible Galaxy. More will come in the next weeks. I also tried to make it simple to install it and do not force dependencies at maximum. Here are parameters you can set: # Select neo4j version neo4j_package: neo4j # community version #neo4j_package: neo4j-advanced #neo4j_package: neo4j-enterprise # Neo4j spatial plugin neo4j_install_spatial: false neo4j_spatial_version: '0.

Ansible: LXC role updated for Jessie

25 February 2015 in Ansible, Debian, Hi-Tech, Linux

Since several weeks, I’m playing a lot with Debian Jessie as a server. I discovered some bugs, reported them to Debian, they’ve been fixed etc…good news! I also wanted to test the new version of LXC. So I decided to upgrade my 2 personal servers to Jessie. But that wasn’t so easy with Systemd. I still encounter non critical issues and going to prepare report bugs for Debian (cgroups issues with systemd).

Generate changelog from git commits and integrate with Sphinxdoc

11 February 2015 in Debian, Developement, Git, Hi-Tech, Linux, Red Hat

For another personal project (that I can’t talk about for the moment ;-)), I wanted to have a Changelog file to get a better following of the infrastructure evolution (configuration management, scripts…all under git). Of course the documentation is very important, but when you do not write it at the same time you’re building the infrastructure, it may be complex to remember each little things you’ve done. That’s why a Changelog can help to understand how the infrastructure has been built step by step.

WordPress: how I almost lost my blog and want to switch

29 January 2015 in Databases, Hi-Tech, Others, Private life, SQL, Web

A few days ago I wanted to play with HAProxy SSL offloading. It was a good experience and alternative to Nginx SSL offloading (I already talked about in this blog). But this is not the topic here… When I was trying to make the offload working on the blog, I modified WordPress options which switched my blog into an infinite loop mode. As it was late and I was tired (bad idea), I just wanted to rollback my changes and needed to recover a SQL backup to do it fast.

Offload SSL with HAProxy

27 January 2015 in Cloud, Debian, HA, Hi-Tech, Linux, Red Hat

A few months ago, I already talked about offloading SSL with Nginx. I also wanted to try it with HAProxy which can be more interesting in some cases. The good On HAProxy, the good thing is the simplicity to do it. First of all you need to have at least the version 1.5 of HAProxy so to get SSL support. Then you only need those lines to offload SSL: frontend frontend-https bind :443 ssl crt /etc/haproxy/ssl/server-unified.

Packer role available on Ansible Galaxy

22 January 2015 in Ansible, Cloud, Hi-Tech

Packer is a really great solution to make an image in several formats (VirtualBox, Docker…). I recently wanted to deploy it on a Jenkins server to automatically perform image build with the help of Packer. That’s why I’ve wrote a Packer role for Ansible really easy to use. You simply have to set (or let them by defaults) vars: # Packer version to install packer_version: '0.7.5' # Packer destination folder packer_destination: '/usr/bin' It will install the desired version :-)

Simple EC2 snapshot released !

20 January 2015 in Cloud, Debian, Developement, Hi-Tech, Linux, Red Hat

For my company, I recently had to find a good solution to make Snapshots from Instance IDs or from tags on AWS. I made several searches but unfortunately didn’t find what I was searching for. That’s why I started to make a tool to do this kind of job. It’s written in Python and requires the Boto library. Here is what you can do with Simple EC2 snapshots: The tool is open source and can be downloaded on GitHub :-).
