first using Centos is going to be very hard for a new to linux user
CentOS 6.5 is a FREE clone of RHEL 6.5
redhat 6.5 is a SERVER class operating system
it is targeted at
1) the server room
2) the corporate office
3) the laboratory ( like the other clone ScientificLinux 6.5)
4) the "workstation "
5 through every number
THE VERY LAST use " Home general purpose use "
cent uses the redhat documentation
and that documentation ASSUMES that you are a accredited ( experienced) redhat administrator
there is a wiki but it is MOSTLY for the old centos 5 OS ( with some centos 6 )
For other "guides" you AS the CentOS/RHEL/SL user need to PORT THEM FOR USE ON CENT
like the Mjmwired guides for Fedora
( you have to change the instructions FOR USE ON Cent/RHEL )
that above might take a year or so to learn
so for HOME use i would NOT !!!!!!!! recommend using centos
Now i do run ScientificLinux 6.5
BUT NOT as my everyday operating system !!!
( video - dvd,.wmv,.mp4,.avi,... and music support is NOT installed )
for that i run OpenSUSE 12.3
if you still want to use CentOS 6.5
go to the BOOK STORE ( brick and mortar or amazon or Barns and noble )
and BUY !!!!!!!!
one or more books
"Red Hat Enterprise Linux 6 Essentials"
for installing software on CentOS 6.5
cent ONLY !!!!! ships with the base and update repos ( software repositories ) where the programs are located on the web
and that is VERY !!!! limited -- VERY LIMITED INDEED !!!
( think software NEEDED to ONLY run a headless server in a server room )
-- NO support for most music
no support for most video
and not much software
for that you need to install third party repos
see the WIKI page
and PAY ATTENTION!!!!!! to the WARNINGS !!!!!
and install set up "Priorities"
you will need to do a lot of reading
