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.
As I do not really have a good blog post for today, here are some things I wanted to talk in a summary. Some good projects have been updated like: WordPress 4: no big updates at the first view but it’s nice to see how this project works and grow (videos, WYSIWYG,…) HAProxy 1.5: Offlloading SSL embedded, Full HTTP Keepalive, ACL enhancement… BIG update! MySecureShell 2.0: Using GnuTLS instead of OpenSSL, available in Debian upstream repositories, new doc… Nginx 1.
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 forgot to talk about 1 meetup I’ve been regarding Neo4j. A friend (evomusic) talked to me about it and as I’m curious, I went to this meetup in July. Neo4j is a highly scalable, robust (fully ACID) native graph database. Neo4j is used in mission-critical apps by thousands of leading startups, enterprises, and governments around the world. I you don’t know what is a graph database, it’s a very good introduction and will help you to understand what it is and how it works.
All, I’m proud to announce my first book available for pre-order! I’m really happy to have finished it and see after several months of hard work that it will be soon available. Who is this book for? MariaDB High Performance is aimed at system administrators/architects or DBAs who want to learn more about how to grow their current infrastructure to support larger traffic. Before beginning with this book, we expect you to be well–practised with MySQL/MariaDB for common usage.
Hello readers! The numbers of readers keeps growing and I really appreciate it :-). Thanks to all followers! You may know that I’m currently writing a book on MariaDB performances/high availability. I’m almost finish and this is the last run before the publication in September. To give the maximum in this book , in the very short delay I have to, I need more time. The current blog post flow is: one blog post every 2 days.
