shejin983 · 10-29-2012, 07:59 AM

I have CentOS 6.2 DVD1 & DVD2 ISO's....

I have an 8GB usb drive..

HOW can I install Cent OS from USB ???
I mean how to make a bootable USB from two ISO files.... so that I can install the cent os from my USB...

This seems to be the official way. http://wiki.centos.org/HowTos/InstallFromUSBkey

Some live cd to usb type creator might work with live centos too.

There may be a few ways. I haven't tested this but grub4dos may be able to directly boot to one iso image. Then when asked to find the second it might show up on the usb or you may have to create a second partition on the usb to find it.

Sometimes network installers can be booted on a usb and then look to either the files extracted to partitions on a usb or the iso image.

and use the CentOS 6.3 dvd !!!
the 6.2 version is NOT supported and you WILL have to UPGRADE to 6.3
so do your self a favor and use a supported operating system .

But my RHCSA syllabus is beased on RHEL 6.2...
So I thought I should use the exact version for CENT OS too....
What u think ???

If this is just for a class then use the 6.2 would be my guess.

you can TRY ??? and that is a big TRY to use 6.2

but the software repos are DEAD
the 6.2 files were MOVED to the historical vault

you will have to manually edit the base 6.2 repo manually
to point to the OLD and NEVER to be updated rpms
--- this is NOT recommended because it is very insecure ---

there are not even the LAST updates around
so all you have is the dvd -- and NO OTHER SOFTWARE

so have "fun" trying

Take no notice of John: he's talking rubbish. From CentOS: "Each CentOS version is supported for 10 years (by means of security updates). A new CentOS version is released approximately every 2 years and each CentOS version is periodically updated (roughly every 6 months) to support newer hardware." In other words, 6.x is good to 2021.

NO this IS THE READ ME
that is the PLACE HOLDER for the 6.2 mirror
http://centos.arcticnetwork.ca/6.2/readme
PLEASE READ!!!!!!!
to quote

Quote:

This directory (and version of CentOS) is depreciated. For normal users,
you should use /6/ and not /6.2/ in your path. Please see this FAQ
concerning the CentOS release scheme:

http://www.centos.org/modules/smartfaq/faq.php?faqid=34

If you know what you are doing, and absolutely want to remain at the 6.2
level, go to http://vault.centos.org/ for packages.

Please keep in mind that 6.0, 6.1 and 6.2 no longer gets any updates, nor
any security fix's.

also 10 years NO
try 7 years
red hat supports it for an extra 3 on a extended support

now if you use the "roling release" that is the ?.x
that is a bit different

The statement I quoted is taken from the CentOS website — that's why it's in quotation marks. If they are mistaken about their own distro, I can only apologise for quoting their mistake.
