CentOS Installation
 

Hello All,

I am going to install CentOS on my system. I have two iso files.
CentOS-6.5-x86_64-bin-DVD1.iso
CentOS-6.5-x86_64-bin-DVD2.iso
How can I install it using bootable usb drive. I have installed ubuntu OS using bootable flash drives but it had only one iso file. I do not know how to install in this case because It has two iso files. I can not use dvd to install. I have only usb port.
Please help.

I have one more question. What is the difference between different CentOS iso files like CentOS LIVE cd iso, LIVE dvd iso, Minimal iso, netinstall iso and bin iso? Which iso should I install? It is very confusing.
I have watched this url.

Please help.
Thank You

--Kind Regards
Sam

Use DVD1, it's all you need. DVD2 just has some extra packages, but if you need those packages you can just grab them from yum once the system is running.

Live CD - a Live session with a bunch of packages stripped out so it can fit on a CD
Live DVD - a Live session that's big enough that it requires a DVD
Minimal - an ISO with just the packages required to install the OS, anything additional you want will have to be installed via yum once the system is running
Netinstall - just the installer itself, all required packages are downloaded from mirrors on-the-fly, which means you must have a working internet connection during the installation process.
bin DVD - the regular installation ISO

Also, you should be using CentOS 6.6, 6.5 is out of date.

Thanks for your solution.

I took a step ahead and download CentOS 7. It took patience and lots of courage (Extra Internet Plan ). It was 6.6 GB. God I wanted to download blueray of Intersteller.

I learnt lots of new things.
Do not use unetbootin to make bootable pen drive for CentOS 7. It will give you boot error and make you think if your 6.6 gb is a corrupt file. Result lots of irritation, impatient and annoyance.
I had to manage a windows laptop to install win32diskimager. While making bootable pen drive it says it may corrupt your device. God will my 16GB pendrive survive? Who says open source is free.

I took risk because I wanted centos on my system ( what was the use of that 6.6 GB file)
Now it did not give boot error and finally I saw the language selection option :)
God I know you are there. After facing some trouble while doing LVM partitions and some force throw out on reboot , finally I was able to install CentOS 7 successfully.

unetbootin does not say it's compatible with CentOS 7, so I'm not surprised it didn't work. I've never used unetbootin, there are plenty of other tools out there. I typically just use lili or yumi, and yumi works just fine with CentOS 7.

There was no reason to get the 6.6 GB iso for CentOS 7, that was a waste of bandwidth (since apparently you're bandwidth-conscious). You should have just downloaded the live or minimal version instead and saved yourself 5+ GB of bandwidth and the associated time.

I'm glad you were able to get it running eventually though, hope you like it.

a word of WARNING with cent7
if you dislike Gnome3 -- have fun --ha,ha,ha,......

also rpmforge IS NO MORE!!!
there are NO!!!!!! el7 multimedia rpms from them

the replacement "repoforge" is not up and ready yet

so have "fun" installing anything

i gave up and deleted the VM image i had

i will NOT !!! be upgrading to 7 any time soon

o you have a linux install on your computer if so dd works.
If you're showing 6.6 G it may be corrupt because the DVD iso is only 3.9G

xfce4 works just fine.

THAT SAID - I have CentOS 7 on my workstation at...work, and I recently had to mount an HFS+ (mac) external hard drive. Digging around, I couldn't find ANY hfsplus utilities in any of the standard or even optional repos (epel, repoforge, none of them). I finally found an el7 hfsplus rpm on pbone.net (not going to post the link here for reasons you're about to see). I installed it without issue, but the installation did take a LONG time (modern quad core xeon machine, plenty of RAM, SSD drive for the OS, and the installation of this little 170kB RPM took a solid 10 minutes). Then I plugged in the drive, issued a mount command, and the entire system shut off. When it booted back up, it wouldn't detect my displays correctly. The right monitor wasn't detected at all, and the left one was the wrong resolution, wrong orientation, and it wouldn't let me change anything. I uninstalled the hfsplus RPM (which again took a solid 10 minutes), rebooted, but no change. Nothing I did made any difference, it WOULD NOT detect my monitors correctly. I even booted into an older kernel, nothing.

I eventually had to reinstall the OS. I almost installed Cent 6 in its place, but I decided to give 7 another go.

normally rhel / cent /sl are not bad about "new versions"
going from 5 to 6 was not a issue
( 4 to 5 with the move from up2date to yum might have caused problems )

7 is different

i will relook at it when 7.1 comes out

Most of the bugs should be worked out by then

but then again the software that i NEED is built for 6
and that will not change any time soon

OP.
i would recommend you stay with cent 6.6 for the time being .

Thanks again to all of you.
Yes CentOS 7 is different. It is surrounded by security concerns all over.

I have to understand lots of new things yet but I have come to know some.

Like you can not give root privileges to any user by editing passwd file making uid, gid 0:0.
You will not have root login on GUI.
I stopped iptables but I was not able to access service, I didnot want to define port there.May be I was doing something wrong or I should have rebooted.
Service command is deprecating, thanks they are redirecting
It doesnt understand what mysql is. mariadb is the new boss.

There are many new things.I hope they will understand me how I operate Linux. :)

MariaDB is a drop in replacement for MySQL:-

I haven't had any problems with MariaDB but I also configured the secure_ installation and answered all of the questions in the terminal-
