Red Hat Knowledgebase

Red Hat Network (RHN) has the ISO images for Red Hat Enterprise Linux and has made them available for download. You can use these images as installation media by burning the ISOs as image files to CD-Rs. Please ensure that you burn the ISO images correctly. You can verify this by looking at the burned image. If you see multiple files and directories, then this should be correct. If you just see the filename.iso as the only file on the CD, then the CD will not boot and will need to be re-burned as an image file. Most CD burning applications will have "Burn as ISO" or "Burn as Image" as an option.

1. Open a browser and go to https://rhn.redhat.com/.
2. Log in with your Red Hat/RHN username and password.
3. Select the Channels from the top menu.

4. Select the channel you require from the Channel Name table. Note: You may have to select All from the Software Channels menu on the left to find the particular channel you desire. A channel would be a base channel, for example, Red Hat Enterprise Linux AS (v. 4 for 32-bit x86) or Red Hat Enterprise Linux AS (v. 4 for 64-bit AMD64/Intel EM64T).

   Alternatively, Select Download Software from the Software Channels menu on the left, then choose the base channel.

5. Click the Downloads link in the sub-menu located under the (base) channel name title. The menu is highlighted with Details by default.
6. Download the ISO images and verify the md5sum. Use the md5sum command with the following notation:

   md5sum filename

7. Burn the ISO images to CDs.
8. Use Disc 1 to begin an installation for Red Hat Enterprise Linux.
