We recommend two good Linux virtual machine image websites that contain applications.

Http://www.turnkeylinux.org/

Http://bitnami.org/

These two websites are very similar. They are easy to install and use. In contrast, I prefer turnkeylinux and the interface is more friendly.

These two websites provide the environment and applications for configuration.ProgramLinux image (. ISO) or virtual machine program (. vmx). We recommend that you download. vmx and run it with VMWare Player.

VMWare Player is a free software. I use ubuntu11.04 and it runs smoothly.

If you want to first try open-source systems such as WordPress, redmine, and TRAC without making too much effort, we recommend that you have a virtual machine now.
