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.

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.

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.

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.

You may remember the first introduction of that tool here. I’ve made changes to support tables’ partition, to avoid a big lock on huge tables. The solution is to rebuild every partition one by one instead of rebuilding the whole table. This is smoother and less stressing Galera. I hope you’ll enjoy this new version (v0.2). Note: I still got issues on MariaDB 10 with such thing, I’m working on it.

I recently played with ElasticSearch Cluster and I totally fall in love! How easy it is, everything is automatic, it works perfectly, wowwww!!! I made a little documentation on how to setup one, you can find it there. ElasticSearch is a really powerful solution and I really like working with it. If you’re searching a full text search solution, try ElasticSearch, you’ll be happy!
