Introduction

  • How to download CentOS 7 ISO Image: Use the following links to download the latest CentOS 7 ISO images from CentOS official download page or its mirror pages. CentOS project team finally released CentOS 7 for 64 bit x86 compatible systems. This is the first major release for CentOS 7 and actual version.
  • A DVD inserted into a CentOS 7 server needs to be used to install CentOS in a virtual machine in the server, but I need the location of the ISO file in order to install it.

Here, we provide ready to use CentOS 7 VirtualBox and VMware images for urgent requirements. The VirtualBox and VMware images are created in such a way that they are less in size but contains all the standard packages required for instant run.

Download Links

We build, maintain and update Cloud images that you can find on our Cloud Images server. These images are built and made available for all the architectures that corresponding version supports. People interested in importing ‘GenericCloud’ images into their own cloud solution can find corresponding images on the link above. Worth knowing that you can also import (through Skopeo or other methods) container ima. Click Add, select the downloaded CentOS 7 ISO. Now, again select it from the file area and click on the Choose button. After this simply click on the Start button. Select Install CentOS 7 boot option. As you boot the machine, there will be an option to run the installer for CentOS 7, select that to move forward.

Both VirtualBox and VMware support OVA & OVF image formats which means you can use VirtualBox image on VMware and vice versa. However, sometime you may face network issues due to interface naming, especially in Red Hat Enterprise Linux derivatives.

How CentOS Linux Makes Verification Possible

The CentOS Project has many donated mirrors (not controlled directly by the project) where you can download ISOs and updated packages. We provide several mechanisms to verify that packages and ISOs on those mirrors are unmodified.

ISOs and Images

Release Announcements

Any page where you can download a CentOS ISO or Cloud image also has a Release Notes link. If you visit the Release Notes page, you will see, on an https page controlled by centos.org the sha256sum values for specific ISO name. This tip tells you how to compare your downloaded ISO's sha256sum to the value from the Release Notes page on many different operating systems. This is by far the easiest way to verify the ISOs, so PLEASE look at the Release Notes or Release Announcement for the ISOs or Images to find the sha256sums.

ISO or Install Image Directories

If you can't find the specific release announcement for the ISO you have downloaded, the directory from which the ISO came will have a sha256sum.txt.asc file that you can use to verify the ISO. This procedure is a bit more complicated and we will go thru how to verify all parts of the process here. The provided sha256sum.txt.asc file is signed with the same key that the specific distribution uses for it's signed packages. I will go through the whole process for CentOS-7 and then explain the slight differences for other versions of CentOS. This procedure requires the linux gnupg package > 1.4 installed.

1. Verify the key used to sign the files

Windows 7 iso download free

First create a validate directory (from the command line) with these commands:

The next thing to do is to verify the KEY used to sign the sha256sum file. You can find a list of keys and fingerprints here. In this example we will verify the CentOS-7 key .. it's name is RPM-GPG-KEY-CentOS-7.

On a CentOS-7 Machine

If you are testing on a CentOS-7 machine, this key is already installed at /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7. If you are on a CentOS-7 machine, you would verify the key with this command:

The output would be this:

File

If the fingerprint matches the one from this list for the CentOS 7 Signing Key, you have the right key installed on your system.

Not on a CentOS 7 Machine

If you are not on a CentOS-7 system, but another version of Linux with at least gnupg 1.4, then you need to download the public part of the signing key, in this case the CentOS-7 key.

Now download a copy of the public key:

Please note that even though this is not an https location, we will verify the fingerprint of key, so you know it is correct no matter where it came from

Now, we will check the key:

The output will be:

If the fingerprint matches the one from this list for the CentOS 7 Signing Key, you have downloaded the right key.

2. Import the Key

We now need to import the key into our keyring. We are working with either /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 or ./RPM-GPG-KEY-CentOS-7.

OR

Please note, you only have to do this step one time to get the key into your local keyring.

3. Download the ISO (or Image) file and the sha256sum.txt.asc files to validate

Once we know we have the valid public key to check the signed files, the next step of the process is to verify that the sha256sum files you want to use are valid. If you were getting the ISO file from here:

Then once you got the ISO, you would also get the sha256sum.txt.asc file from the same place. In this particular case, from the following locations.

Once you have the sha256sum.txt.asc file, you would verify it like this:

The output will look something like this:

Please verify the Primary key fingerprint listed is the correct one from this list (we did that above, you can do it again if you prefer)

Once you have verified the signature of the sha256sum.txt.asc file, please make sure you have the ISO (or image file) and the sha256sum.txt.asc file in the same directory. You can then verify the ISO or image file with the following command:

The output in this example is:

4. Other Locations

The only real difference for CentOS 6 ISOs is that the name of the key would be: RPM-GPG-KEY-CentOS-6

You would still use the sha256sum.txt.asc file from the directory where your ISO is located and still import the key once you verified it's Fingerprint.

If you are instead trying to verify a CentOS image from this directory:

CentOS 7 Cloud ImagesSteps still the same, use the sha256sum.txt.asc file from the directory where your ISO is located and still import the key (in this case, RPM-GPG-KEY-CentOS-7 for those cloud images) once you verified it's Fingerprint.

So the basic steps are

  • Verify a Key
  • Import that key
  • grab the image or iso file
  • grab the sha256sum.txt.asc file from the same directory as the iso or image file
  • verify the sha256sum.txt.asc signature
  • verify the iso or image from the sha256sum.txt.asc file

With those steps, you can always verify that your ISO or image is the one released by the CentOS Linux team. You can do this no matter where you got the public key or the image/iso file .. as it relies on gpg key signing.

Using signed CentOS-6 or CentOS-7 Metadata for Repositories Released by the CentOS Project

What is Signed Metadata for Repositories

Using signed metadata means that yum checks that there is a repomd.xml.asc signed by the key listed for that repository. This means that you know this information is what was released by the owner of that key.

Repositories Where Signed metadata is Provided

The CentOS Project provides signed repomd.xml.asc files for the following CentOS Repositories for CentOS-6 and CentOS-7:

  • extras
  • cr
  • centosplus
  • fasttrack
  • updates

For any of these 5 repositories, you can enable using signed metadata in CentOS-6 or CentOS-7.

The yum included in CentOS-5 does not properly support using signed metadata, so CentOS-5 does not have signed repositories.

How to Enable Using Signed Metadata

If you edit the applicable repository file, you will add the following line to the applicable repo section:

The updates, extras, and centosplus repo sections exist in the file /etc/yum.repos.d/CentOS-Base.repo

Centos 7 Download Linux

The cr repo section would be in file /etc/yum.repos.d/CentOS-CR.repo

The fasttrack repo would be in the file /etc/yum.repos.d/CentOS-fasttrack.repo
