CentOS 7 (1611) for the i386 32-bit architecture has been released The CentOS AltArch SIG is a group of people working to build alternative architecture support derived from CentOS Linux's sources.

CentOS developer and maintainer Johnny Hughes is announcing today, January 30, 2017, the immediate availability of the latest CentOS 7.3 (1611) GNU/Linux operating system for the 32-bit (i386) hardware architecture.

If some of the most popular GNU/Linux distributions have started dropping support for 32-bit (i686/x86) installations or plan to do so in the near future, many are still installable on older computers from 10 years ago.

CentOS 7.3 (1611) is the latest addition to the list of 32-bit supported Linux-based operating systems, thanks to a group of hard working people from the CentOS AltArch SIG initiative trying to create alternative architecture support for CentOS Linux.

'This is the release announcement for the i386 (Intel 32-bit) Architecture based on the source code released for CentOS-7 (1611). It includes all packages that build on x86 32-bit processors,' said Johnny Hughes in today's announcement.

GNOME and KDE Live ISO images now available for download

The good news, however, is that today's release of CentOS 7.3 (1611) Linux distro for 32-bit hardware architectures also comes with a couple of Live ISO images bundled with the GNOME and KDE desktop environments.

As such, you'll be able to test drive the operating system with either KDE or GNOME on your personal computer without installing anything on the local disk drive. Of course, DVD, Everything, Minimal, and NetInstall ISO images are also available for download.

Existing CentOS 7 32-bit users don't need to download anything, just open a terminal emulator and run the 'yum update' command as root, which will automatically download and install the latest package versions.

We remind you that CentOS 7.3 (1611) is based on the freely distributed source code of Red Hat Enterprise Linux 7.3 and you can also download the official, 64-bit ISO images directly from our website if you want to install the operating system on your PCs.

If you have a Red Hat subscription, you can download ISO image files of the Red Hat Enterprise Linux 7 installation DVD from the Red Hat Customer Portal. If you do not have a subscription, either purchase one or obtain a free evaluation subscription from the Software & Download Center at https://access.redhat.com/downloads/.
There are two basic types of installation media available for the AMD64 and Intel 64 (x86_64), ARM (Aarch64), and IBM Power Systems (ppc64) architectures:
Binary DVD
A full installation image that boots the installation program and performs the entire installation without additional package repositories.
Binary DVDs are also available for IBM Z. They can be used to boot the installation program using a SCSI DVD drive or as installation sources.
Boot.iso
Centos 7 32 Bit Iso Download Linux
A minimal boot image that boots the installation program but requires access to additional package repositories. Red Hat does not provide the repository; you must create it using the full installation ISO image.
Supplementary DVD images containing additional packages, such as the IBM Java Runtime Environment and additional virtualization drivers may be available, but they are beyond the scope of this document.
If you have a subscription or evaluation subscription, follow these steps to obtain the Red Hat Enterprise Linux 7 ISO image files:

Procedure 2.1. Downloading Red Hat Enterprise Linux ISO Images

Centos 7 32 Bit Iso Download Linux 10

  1. Visit the Customer Portal at https://access.redhat.com/home. If you are not logged in, click LOG IN on the right side of the page. Enter your account credentials when prompted.
  2. Click Red Hat Enterprise Linux.
  3. Ensure that you select the appropriate Product Variant and Architecture for your installation target. By default, Red Hat Enterprise Linux Server and x86_64 are selected. If you are not sure which variant best suits your needs, see http://www.redhat.com/en/technologies/linux-platforms/enterprise-linux. Additionally, a list of packages available for every variant is available in the Red Hat Enterprise Linux 7 Package Manifest.
  4. A list of available downloads is displayed; most notably, a minimal Boot ISO image and a full installation Binary DVD ISO image. These files are described above. Additional images can be available, such as preconfigured virtual machine images, which are beyond the scope of this document.
  5. Choose the image file that you want to use. You have two ways to download it from the Customer Portal:
    • Click its name to begin downloading it to your computer using your web browser.
    • Right-click the name and then click Copy Link Location or a similar menu item, the exact wording of which depends on the browser that you are using. This action copies the URL of the file to your clipboard, which allows you to use an alternative application to download the file to your computer. This approach is especially useful if your Internet connection is unstable: in that case, you browser might fail to download the whole file, and an attempt to resume the interrupted download process fails because the download link contains an authentication key which is only valid for a short time. Specialized applications such as curl can, however, be used to resume interrupted download attempts from the Customer Portal, which means that you need not download the whole file again and thus you save your time and bandwidth consumption.

      Procedure 2.2. Using curl to Download Installation Media

      1. Make sure the curl package is installed by running the following command as root:
        If your Linux distribution does not use yum, or if you do not use Linux at all, download the most appropriate software package from the curl web site.
      2. Open a terminal window, enter a suitable directory, and type the following command:
        Replace filename.iso with the ISO image name as displayed in the Customer Portal, such as rhel-server-7.0-x86_64-dvd.iso. This is important because the download link in the Customer Portal contains extra characters which curl would otherwise use in the downloaded file name, too. Then, keep the single quotation mark in front of the next parameter, and replace copied_link_location with the link that you have copied from the Customer Portal; copy it again if you copied the commands above in the meantime. Note that in Linux, you can paste the content of the clipboard into the terminal window by middle-clicking anywhere in the window, or by pressing Shift+Insert. Finally, use another single quotation mark after the last parameter, and press Enter to run the command and start transferring the ISO image. The single quotation marks prevent the command line interpreter from misinterpreting any special characters that might be included in the download link.

        Example 2.1. Downloading an ISO image with curl

        The following is an example of a curl command line:
        Note that the actual download link is much longer because it contains complicated identifiers.
      3. If your Internet connection does drop before the transfer is complete, refresh the download page in the Customer Portal; log in again if necessary. Copy the new download link, use the same basic curl command line parameters as earlier but be sure to use the new download link, and add -C - to instruct curl to automatically determine where it should continue based on the size of the already downloaded file.

        Example 2.2. Resuming an interrupted download attempt

        The following is an example of a curl command line that you use if you have only partially downloaded the ISO image of your choice:
  6. Optionally, you can use a checksum utility such as sha256sum to verify the integrity of the image file after the download finishes. All downloads on the Download Red Hat Enterprise Linux page are provided with their checksums for reference:
    Similar tools are available for Microsoft Windows and Mac OS X. You can also use the installation program to verify the media when starting the installation; see Section 22.2.2, “Verifying Boot Media” for details.

  • Burn it to a CD or DVD as described in Section 3.1, “Making an Installation CD or DVD”.
  • Use it to create a bootable USB drive; see Section 3.2, “Making Installation USB Media”.
  • Place it on a server to prepare for a network installation. For specific directions, see Section 3.3.3, “Installation Source on a Network”.
  • Place it on a hard drive to use the drive as an installation source. For specific instructions, see Section 3.3.2, “Installation Source on a Hard Drive”.
  • Use it to prepare a Preboot Execution Environment (PXE) server, which allows you to boot the installation system over a network. See Chapter 23, Preparing for a Network Installation for instructions.
