phpMyAdmin is a great tool written in PHP intended to handle the administration of MySQL or MariaDB with the use of a web browser. For security reasons I have been using it over https. Till version 4.6.0 you could force using https instead of http with just configuring the config.inc.php
Executing multiple git post-receive hooks on git/gitolite server
In a past post of mine called Integrate git/gitolite server with slack I have mentioned how you could add a hook to your git/gitolite repository that would notify a slack channel about pushes made on your git server. But what about when you need to have multiple post-receive git hooks?
KVM guests and synhronizing clock
I was launching a couple of Ubuntu 14.04 KVM guests and I ve noticed that time was wrong. OK I thought, a simple ntpdate command and ntp service enabled will fix the issue. Made a reboot of the guest host and show that the time was ok. Then I destroyed the guest and when I checked the time it was wrong. This can’t be right, I thought, and started researching what might be the issue. What I found is that KVM guests should always consider their hardware clock in UTC time while my guests configuration was in local time.

How to issue SSL certificate with Subject Alternate Names for private chef server
I was trying to migrate a private chef server from ubuntu 12.04 to ubuntu 14.04 . I thought that it would be great to use Alternate Names in the certificate that I would be issuing. The certificate would be self signed but one of the issues I have faced was that ssl verification failed from the client and as reported by knife ssl check.
Integrate git/gitolite server with slack
In a project I have been working due to lack of funds we have been using our own git central server and not github or bitbucket. Access control is managed by gitolite. Our team is using slack as a collaboration tool. What we would like is when a developer pushes back to our repository/repositories then every developer is notified through slack.
Issue with vagrant-berkshelf plugin and upgrading chefdk
Running test-kitchen with other than .kitchen.yml configuration file
Till now I have been testing my chef cookbooks using kitchen on my laptop, which means that it’s done with vagrant and virtualbox as its provider. One of the things I wanted to try is to add jenkins in the whole process. I can only have a jenkins server as a KVM guest so this means that I can not have virtualbox as vagrant’s provider since VirtualBox can not run inside KVM.
Network issue with cloning a CentOS 6 VM
As a mentioned in previous posts I have created a simple script that would clone/configure a KVM guest based on existing templates. The scripts can be found in my github https://github.com/mrdimka/kvm-scripts . When I tried to launch a CentOS 6 VM I ve noticed that eth0 was not configured and was failing.
Issue while creating a CentsOS 7 KVM Guest
It’s quite sometime since RHEL/CentOS 7 (2014-06-09) was released so a few days ago I thought I should try it out and maybe create a KVM Guest template in case I need it in the future.
