Last week I posted about upgrading my servers to CentOS 7, one of the main factors about upgrading to CentOS 7 was the jump in kernel version (from 2.6.x to 3.10.x). Also, it was so that I could use more modern versions core of software without having to worry about installing numerous additional repos. The funny thing is that all of the software I have been waiting to use have been available in both Fedora↗ and Ubuntu↗ for quite a while, so why have I waited? ...
==PLEASE NOTE: THESE INSTRUCTIONS ARE NOW OUTDATED, SEE THIS POST FOR AN UPDATE== After I dabbled with CentOS 7 a few weeks ago I decided to take the plunge and upgrade the few servers I run at DigitalOcean↗ to CentOS 7. I run two machines, one is a Puppet and Salt Master, the second runs Docker. Puppet Master Server A while back I added a few bash scripts to deploy both a Puppet Master & Agent↗ to GitHub, as Puppet provide a repo for CentOS 7 I decided to just update the installation script to use this repo and then give ago. I use stephenrjohnson/puppet↗ to deploy the Puppet Master. the Puppet part worked, however it failed to install Passenger and its Apache module because there is no mod_passenger available for CentOS 7 yet. To get around this I grabbed the require packages from The Foremans nightly builds↗ repo. This turned the initial yum install line into the following; ...

As part of another work project I needed to install some central logging to run in AWS. Simple you may say, create an instance and use Puppet to install ELK server stack↗ on there, or go back to basics and create a rsyslog↗ server. Normally this would be well and good, however I needed to ensure that all parts solution were highly available and fully redundant, this meant that I would have engineer a lot of HA into my ELK or rsyslog servers. ...
I am currently working on a technical project for work where I need to keep a combination of code and technical documentation together, at the moment it is only me working on the project though other people may start to contribute later. Normally on projects like this I dump all of my work in either a Google Docs ↗ document or use files in Basecamp↗ however as this was mostly technical documentation along side snippets of code I decided I wanted to use Markdown↗ . ...
As I didn’t get chance to have a play with the pre-release CentOS 7.0 builds I decided to wait until DigitalOcean↗ lauched their image↗ which they did just in time for the weekend. Check the IP Address First thing I did was type in ifconfig and got ….. First play with CentOS 7.0 1/5 [root@server ~]# ifconfig -bash: ifconfig: command not found ….. not a good start, have dabbled with a Fedora↗ when I installed OpenShift I remembered about the ip command ….. ...
I have been missing in action for a while, busy with work and other “stuff”. Since I last posted ….. Docker 1.0 has been released.↗ CentOS↗ 7 has been released↗ . I have updated the sites theme again to use So Simple↗ . Aphex Twin’s Long Lost Caustic Window LP was released.↗ Also new albums from Neil Finn↗ , Anathema↗ and Crippled Black Phoenix↗ have all been released. I have written a blog post for work↗ on MFA in AWS. ….. suppose I had better make more of an effort to post now that everything has caught up. ...
Having ran a local copy of OpenShift Origin↗ using VirtualBox↗ I decided to have a go at running it on a Digital Ocean↗ Droplet running CentOS 6.5. This should be easy as there is an installer↗ which claims; You’re one shell command away from deploying your own Platform as a Service. Well, sort of, after a few failed installs I finally managed it using the following (this assumes you are running a clean and minimal CentOS 6.5 installation) ...
