CentOS7 Installation |Bottleneck |

Post by jmacdougca » 2019/06/16 21:05:45

Hey guys,I am trying install CentOS7 over my current machine(Fedora), the walkthrough is taking me to a local host login. I don't know what this is, I tried my user and password for root access login but it does not work?

When I try install to a hard drive says no room:

What I really want to do is a fresh install of CentOS7 on one of the IntelSSDs. I am in bit of a pickle here. I am open to other options to achieve the goal of installing CentOS7 on one of the intel SSDs

Huh?!? I'm lost here. One one your bootable options says CentOS. As ridiculous as this sounds, did you highlight and and hit enter the option that says CentOS?!?

Assuming you want to install CentOS 7.6 on a HDD or SSD, and assuming you know *which* HDD or SSD you want to install it on -- not a VM, but an actual physical install -- first run fdisk -l to find out its device name ( /dev/sd* where *=a-z), as well as its size and I.D. (Intel model # and size). As a safety precaution disconnect all your other devices except for you CD/DVD or USB which should be the first drive the computer boots from.

Next find a mirror and burn an an .iso to a DVD ( CentOS-7-x86_64-DVD-1810.iso ). Reboot the machine and the install menu will pop up and you can be on your Merry Way.

A word to the wise: Install as a LEGACY BIOS, not UEFI, unless you are forced to. It will save you a lot of headaches.

If this does not answer your question it may be because I am not sure what you are asking.

this option brings me the the local host login screen shot i attached.

sda2 is where i want to install the image. But when I get to assign an installation disk in the installation process it says my hard drives have 0 free space apparently. I attached a picture in the original post

I have a USB bootable .iso that is working fine. Again I can't assign a HD to it.

Neither your username + password nor "root" + root password works as intended to login to CentOS?

Just select the hard disk sda anyway and select "I will configure partitioning" in the options below. When pressing "Done" afterwards, you will get the opportunity to select partitions for yourself.

OK IF there is is ZERO (0) free space is left that means that the disk is full. There are a few things you can do. I still would disconnect all the other drives as a safety precaution first so that the ONLY drive that is connected is the one you wish to write to, that way you can't accidentally overwrite a drive you don't want overwritten.

The easiest thing to do is what owl102 says: select Custom install set up the partitions, and after that it will say do you want to format, say Yes; alternately you also have the option to erase the existing data, once that is done partition as you would like, it will say format the partition, and be on your marry way.

A second alternative is simply to use GParted and simply erase the existing drive, and reformat the entire drive, then proceed with the install. Now 100% of the drive will be available to receive new data. The great thing about GParted is you can visually see exactly what partitions currently on the drive, and you can then opt to erase them, and then reformat the entire drive. Indeed when I discover an old funky drive in a hand-me-down the first thing I do is reformat the drive using GParted. That way I *know* there is *nothing* on the drive, after that I then proceed to do the fresh install using the Custom Install, with Custom Partitions. Do yourself a favour and make sure all the partitions are set up as ext4 partitions. An alternative here is once you have used GParted and reformated the entire drive, during the install if you don't want to go the the Custom partition route you can allow the machine to do it using LVM -- it does not matter now as you already have a "clean" reformated drive to start with, whereas if the disk is full... you might get an error message such as the one you are getting.

In other words the first thing you need to do is to erase the data on the drive before you can create new partitions. If you know the CentOS install program upside down and sideways, go that route; otherwise use GParted to first erase the current partitions and then reformat the drive.

Again set it up to use a Legacy BIOS, NOT UEFI.

root +root doesn't work.

Thanks for this tip. I tried to add a disk but there was an error:
Picture: https://www.dropbox.com/s/7v12najp9ies8 ... 2.jpg?dl=0
Picture2: https://www.dropbox.com/s/ep3suk55qpixt ... 2.jpg?dl=0
Saying no free space. Yup the disks are full.

Also when I try to boot my device in legacy mode the machine fails. does nothing. When I boot in UEFI mode the installation begins.

Now as for gparted: I like this approach. Just wipe the two hard drives I have and do an install. How do I run gparted though if i am trying to reformat the HD the OS is running on? Can I run a terminal and then do gparted from the commandline and wipe out the OS? If so cool.

Thanks for the help so far.

Trying to create partition in installation.
I tried / and /boot as mount points.

YUS! gparted worked! one tip was the dropdown bar to select your various disks.

CentOS7 installed. But now I can only log into the cmd is this because I installed a minimal install? I wanted to keep this machine as a working computer.

In the CentOS7 install it is not showing sda3 as a selectable partition. Am I supposed to do something so the installation will pick it up?
