MySQL on CentOS 6 - via SCL 
RedHat offers a nifty little collection of add-on software:

"Enterprise Linux distributions are designed to be around for a long time. They are also designed to maintain ABI/API compatibility over the lifetime of the distribution, so that you can create your own custom programs on day 1 of the release and have them work as long as the distribution is supported. For CentOS that is currently 10 years. This means, however, that by the end of the lifetime of a distribution, the programming language or database versions (think php, python, perl or mysql, postgresql) included are getting very old compared to those that are available in "cutting edge" Linux distributions.

For many enterprise users, that is OK ... Think a major retailer who spent $10 Million to create an inventory solution using the default languages available and they want to leverage that solution securely for the entire 10 year lifespan to get a return on their programming investment. But many enterprises also want to be able to create software with newer programs as well. They want both stability AND newer software. They want it to work alongside the other system software so they can choose slow and steady or newer software for development.

Enter Software Collections, also known as SCLs. As an example, SCLs allow you to run the default python that comes with CentOS (so yum and other system tools in CentOS work), while also allowing a newer version of python to be installed alongside the default python for use creating and running software with newer requirements."

What a great idea!

Here is what we did:

su
yum install centos-release-SCL
yum install mysql55

For those of us who are used to spending several hours downloading, patching, and integrating ad-hoc super-distro tech, the above three line script might seem positively revolutionary.

su
yum install postgresql92

Other goodies include more recent versions of Python, Ruby, PostgreSQL, and more. -Follow the "Related Link" (below) to see the 1.0 of yet another truly inspiring idea from Red Hat!



-Enjoy the upgrade!

Filezilla on CentOS 6 
Another essential tool.

When you see "No package filezilla available", just:

su
rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpm ... f.i386.rpm
yum install filezilla

That RPM path is h-t-t-p://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

After installed, merely type in `filezilla` at the command prompt to fire-it up.

One might also notice that the screen-shot ability is not part of the Live-CD installation process. To enable ALT+Print Screen on CentOS where lacking, simply:

su
yum install gnome-utils -y
(source)


Cheers,

Virtualbox on CentOS 6 
Well, it is time to leave Ubuntu behind. Not only has the UI become so odd that students are inadvertently deleting files, but the new user interface is - to say the least - intrusive, as well as unpredictable.

Most of my associates are running either Red Hat or CentOS. -Now we will be doing so, as well.

Here is how to install Virtualbox on CentOS 6:


cd /etc/yum.repos.d/
wget http://download.virtualbox.org/virtualb ... albox.repo
yum update
yum install binutils qt gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms
yum install VirtualBox-4.3
service vboxdrv setup


That wget path is h-t-t-p://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo

Worked great on my machine. See the related link (below) for the source of the above scrips, as well as for other platforms.
