Virtualization and something more...
CentOS 6.2 ships with Python 2.6.6 and depends on that specific version. Be careful not to replace it or bad things will happen. If you need access to a newer version of Python you must compile it yourself and install it side-by-side with the system version.
Here are the steps necessary to install Python 2.7.6. Execute all the commands below as root. Either log in as root temporarily or use sudo.
You'll need to get a usb-serial adapter and then connect with a console cable.

Today we will install chef server in our home lab based on proxmox 3.4.6. So we have installed server 2cpu, 2Gb memory, Centos 6.7
First of all I switched off selinux, and configured hostname of server in /etc/sysconfig/network and /etc/hosts
Let's go on:

More and more people reconfigured their sites to ssl connection. So I decided to use ssl certificate and secure connection on my blogs too.
The Chinese CA WoSign offers free SSL certificates which are valid for 2 years and may contain up to 100 domains each (multi-domain/SAN/UCC) which is very useful to host various domains on one single IP address (Better option than SNI if you still have Windows XP clients). Before you stop reading because you don't trust a Chinese company for your website encryption please keep in mind that you don't have to trust them at all! You generate the SSL key on your server and only send them the CSR (certificate signing request) which doesn't contain any private information.
Today we need to get a wildcard SSL certificate into a Java Keystore format. First copy everything you need to a /tmp folder. There are gd_bundle.crt , domain.com.crt and domain.com.key
After some manipulations described in this post you can receive this error
