2 Why use Scientific Linux?
Scientific Linux is the worldwide reference operating system for scientists and scientific
applications at this beginning of the 21st
century and created in 2004!
among a lot of other distributions:
Scientific Linux forum:
http://scientificlinuxforum.org
You can download the complete 31 Gigabytes Scientific Linux Virtual Box (vdi file) here1
:
https://www.dropbox.com/s/g1p1rymql4x45o4/ScientificLinux7.vdi?dl=0
with all installed stuff detailed in this PDF here:

The password of the Virtual Machin account is: password

https://fr.scribd.com/document/278466634/Scientific-Linux-Virtual-Box
If necessary you can check the kernel version with the following command:
2.1 Updates
When you update the applications of your system (yum update) the kernel will also be updated
and then when start your computer you will get:
To see the list of installed Kernel:

To remove an old Kernel just type:
Upgrades between major versions (from SL 5 to SL 6, or SL 6 to SL 7) are not supported!!!

You will get and click on Edit:

41/216
And activate:

42/216
4.2 Auto log-on

We install Apache:

77/216
We start the server on we change to configuration to make it start automatically at every boot:
Now to make the whole LAMP works correctly we must configure an iptable. We create and

When finish, write ESC + : wq and Enter to save and return to the terminal.

If and only if you can't still access to phpMyAdmin do the following:

101/216
So we can change the following file:
And you change:

7 Science
7.1 R
As we all know, R is actually the most complete statistical software in the world. So we need it
for number analysis
Therefore first thanks to the fedora repo:

144/216
We make an update to be sure to have the last version:
Now we launch R by typing just… R… (not userfriendly but terribly efficient access):

145/216
It may be useful also to know how to uninstall R as sometimes it can be corrupted. Then run the
following commands:
yum uninstall R
yum uninstall R-core
yum uninstall R-devel
yum uninstall R-core-devel
If you get an error when running R for the first time saying that a file is missing in a given folder.
Just go in this folder and copy paste in an existing file in that same folder having a similar name
and just rename it as expected by the R error message!
After you just have to read my R 1'700 pages book on R ;-)

That brings us to:
Wait… almost 3000 modules (LaTeX packages/*.sty) to install…

163/216
To install TeXMaker on SL 7.1 we will need to recompile TeXMaker code source. Then before
we install QT4 compiler!:
yum install pkg-config qt-devel qt-webkit-devel poppler-qt4-devel gcc-c++ make rpmdevtools
