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.

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).

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.

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.

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 :-).

Following the deployment blog post I made on ES/Kibana/Fluentd, I released new version of Fluentd and Kibana playbooks to support the latests versions of themselves and ElasticSearch. ElasticSearch 1.4 version is ,out which doesn’t changed anything for the deployment. However Kibana requires to enable an ElasticSearch configuration option now, to work properly. I updated the Kibana playbook for it. On its side, Fluentd has the major release 2.0 out and I updated Ansible playbook for the best integration with Debian Wheezy.

I recently had the case, where I lost connexion of my NFS client connexion because NFS server crashed. The problem I had is simple, some of clients couldn’t recover their connexion because the old one was still shown as already connected. And when I tried to remount NFS clients connexions, I got: mount.nfs: mount(2): Protocol not supported mount.nfs: trying text-based options 'udp,sec=sys,rsize=8192,wsize=8192,intr,hard,addr=10.0.0.1' mount.nfs: prog 100003, trying vers=3, prot=17 mount.nfs: trying 10.
