I am going to be playing with OpenStack over the next few weeks so I decided to create a Vagrant script which would bootstrap a working OpenStack Kilo↗ installation using RedHat RDO↗ . It uses my CentOS 7 Vagrant box↗ and works with both VirtualBox and VMWare Fusion. To get it up and running create a folder for the Vagrantfile to live; Quick OpenStack Kilo Installation 1/4 mkdir -p ~/Machines/OpenStack/ Download a copy of the Vagrantfile;...
After being nagged by the gaffer to try OpenShift Origin V3 I finally got round to running a test server using Vagrant on my Mac. I must say, going into this that the documentation at this stage is struggling a little to keep up with the development and these instructions are the results of much trial, error & Googling. Also, the product is very much still in active development and there have been several bugs, like this one↗ , which have caused the instructions below not to work....
I haven’t installed an ELK stack since CentOS 7 came out, all of the components which go to make up the stack have been updated quite bit since then so I decided to have a go at installing the stack on a clean CentOS 7 installation. ELK? ELK is a term used for a combination of three Open Source products from Elastic↗ ; Elasticsearch↗ — Search & Analyze Data in Real Time Logstash↗ — Collect, Parse, & Enrich Data Kibana↗ — Explore & Visualize Your Data All three products can be used independently, but when they are used together you find yourself with both a powerful and scaleable central logging service....
I spent Wednesday out of the office at the 2015 AWS Summit in London. It was the first time I had been to a full on AWS event and I must say I was impressed by the scale (pun intended). The main keynote was interesting, and it was great to hear all about new Elastic File System↗ which is going to be a godsend for those who need to have some level of shared storage....
As everyone who knows me will already know, I am a little bit opinionated when it comes to music. However, I haven’t really had a decent sound system for quite a few years. I decided mid last year that I would do something about it and not only start getting back into vinyl (I know, such a hipster) but also get a decent sound system, so started saving. For quite a while I was looking an all-in-one system like the Teac LP-P1000↗ however, I decided I would end up painting myself into a corner with it as I would be only be able to use it in one room, I then started looking at other options....
One of the first things I do on a new server is install fail2ban↗ . I have written about it before, but that was back when I was still using CentOS 6. Now I am using CentOS 7 the installation has a few more steps. Firstly, as EPEL is not enabled by standard on most CentOS 7 installations enable the repo and then install fail2ban. Fail2Ban on CentOS 7 1/8 yum install -y epel-release && yum install -y fail2ban Once installed you can run the following to setup a check and block for failed SSH logins (it bans for 24 hours after three login failures);...
As you may have noticed, the blog looks different (again). This is because I have moved from Wordpress↗ back to Ghost↗ using their GhostPro↗ offering. One of the things I like about Ghost is the default theme, Casper↗ . While I wanted to keep it there were a few things I wanted to tweak, such as removing the full page header image on main index. When I have previously used Ghost I have forked the theme on GitHub and then manually messed about getting any updates from the original code in....
Since I last properly [wrote about Docker](/2014/08/31/docker-fig-nginx-reverse-proxies-and-centos-7/“Docker, Fig, NGINX Reverse Proxies and CentOS 7”) a lot has changed. Docker have introduced some new command line tools which allow for easy orchestration of Docker instances, clusters and container management. These are; Docker Machine↗ — Allows you to easily deploy Docker instances to a lot of different platforms. Docker Compose↗ — A replacement for Fig↗ . Docker Swarm↗ — Native clustering for your Docker instances....
