hi all,im new here and this is my first post so please bear with me and if i did anything wrong please tell me...
I am asking this because i just joined RHCE course recently.so to study i have to download the Red Hat Enterprise Linux to study the os.but since i am jobless and i cant afford to buy that and i dont want to download the evaluation version.i heard that centos and fedora are sumwat similar to redhat enterprise linux and are free[correct me if i am wrong].so what should i download to study the os?i meam if they are somewhat or almost same i could use the free version and later i could buy the Red Hat Enterprise Linux when i gat a job.thanks for ur replies..take care
Welcome to LQ.
At first, please don't use text-/SMS-speak, this is not appreciated here.
I would recommend to use CentOS, it is RHEL recompiled without the Red Hat branding. Other than the missing branding it is 100% compatible, so it would be the best to learn for the certification.
Fedora is used as a testbed for RHEL, to work out the bugs in new versions of software before they're implemented in RHEL. As a result, the overall layout of Fedora and the usage of the package management system will be the same as RHEL, however Fedora will be more unstable and the look and feel will probably be very different. CentOS would provide a better 1:1 comparison with RHEL.
Live cds are mostly for demoing distros. If you plan to make/test any changes to the OS, you'll need a persistent install, otherwise anything you modify will be lost the next time you reboot. I can't imagine truly "getting to know" any OS without being able to make persistent changes to it.
If you don't want to bother with partitioning and bootloaders I would recommend to install Virtualbox and install CentOS into a virtual machine. This way you can also use the snapshot feature to go back to a known good state of the OS, if something weird happens.
Thanks for the answers.since im a newbie i just want familiarise with redhat or centOS for initial 5 days.so i guess the live cd will be enough?coz its smaller than the centos os and after some days i will switch from live cd to os.but can i install the centOS 6.0 live cd to my hard disk?if so that will save some time downloading the o.s.i found some ways to install the 5.0 version but i am completely clueless abt installing the 6.0 version.
I also recommend TobiSGD's suggestion. Download and install VirtualBox (its free) on your windows 7 install, and then install CentOS onto a virtual machine, and run it form within windows.
This will also make things easier with other hurdles along the way, that whilst you are learning if you lose your network connection with the CentOS install, you wont be able to look up how to get it back, etc.
