This video shows the Scientific Linux CERN 6.3 installation. For a sake of simplicity, this will be done in a virtual machine (VM).
I'll start creating a new virtual machine for the Linux.
Instead of using a real DVD media, I'll use those ISO files shown in the previous tutorial.
The Operating System is Linux and I'll use the configuration for a 64 bits version 2.6 kernel.
I'll give a meaningful name for the file (folder) in which the VM will be saved.
The VM starts. I'll stop it because there is some additional configuration to be done.
First of all, I'll change the number of processor to two, as this actual hardware is dual core. I'll also increase the amount of RAM to use 1GB of the 4GB of my real hardware.
Let's increase the size of the virtual hard disk. The virtual hard disk is actually system files.
20GB shoud be ok. I'll not allocate all this space now. The VM will allocate it on demand.
Let's start the VM. It will boot from DVD which is in fact the DVD1 ISO file downloaded from the CLC6.3 website.
The keyboard arrows can be used to choose one of the menu items. I type "Enter" to choose de marked default option, the first one. From this menu it is also possible to choose text based installation.
The VM restart ...
At this point, it's possible to test the media integrity. I won't do that because it's was already done in the previous video with openssl and the signature file (message digest).
The actual installation process starts.
The graphical environment starts.
Choose the language of your preference.
This time you must choose the configuration of your keyboard.
Choose the regular file system.
Press "Yes" to continue. This is only a warning message informing that the disk will be written.
Choose the standard configuration. You can set all this network thing afterwards.
Choose your timezone. I'll choose my time zone which is "São Paulo". It can be changed after installation.
ATTENTION: choose the "root" user password and write it down. This give access to everything in the system.
It is important you choose a good password. In this case I chose a weak (and easy to remember) password because this is a test.
Choose the default option. The first option can also be chosen, especially if the target disk is being used exclusively for the Linux. Those other options should be used in the case you want to install the Linux in a disk that have other partitions and/or other Operating Systems.
No big deal here. The disk will be written.
Choose the Desktop option for this machine. I think this is the best option for GEANT4 beginners.
Below is shown the Scientific Linux as the software repository. This will be important to install some software after installation in order to configure the system for GEANT4.
Do you have your DVD medias available? If you have them, then continue.
Copying files from the DVD to the HD.
This copying process can take a while.
Time to change from DVD1 to DVD2.
In this case, I'll change the ISO, not the actual media.
The process resume.
The "boot loader" is being installed. This is an especial piece os software responsible for the primary system start.
The installation is now completed. There is a couple of additional things to be set up.
Here is the boot loader. By pressing any key it's possible to choose another OS, if this was the case.
The system starts.
A few additional set up.
Let's create an user called "geant4" that I'll use to work with GEANT4. You can choose a different name.
Again, as this is a test, I'll choose a easy to remember password.
These are some configurations that can be done afterwards. They are no important.
Don't worry about this. I don't think this is gonna jeopardize the use of GEANT4.
Logging in on the system using the geant4 user.
Voilá!!!
Let's shut the system down.
Thank you!!!
