红帽全球峰会第 25 章 Troubleshooting after installation
The troubleshooting information in the following sections might be helpful when diagnosing issues after the installation process. The following sections are for all supported architectures. However, if an issue is for a particular architecture, it is specified at the start of the section.
25.1. Resuming an interrupted download attempt
You can resume interrupted RHEL ISO image downloads using the curl command to avoid re-downloading large files from the beginning. It saves time and bandwidth when network interruptions occur during the download process, ensuring efficient acquisition of installation media.
Prerequisites
- You have navigated to the Product Downloads section of the Red Hat Customer Portal at https://access.redhat.com/downloads, and selected the required variant, version, and architecture.
- You have right-clicked on the required ISO file, and selected Copy Link Location to copy the URL of the ISO image file to your clipboard.
Procedure
Download the ISO image from the new link. Add the
--continue-at -option to automatically resume the download:$ curl --output directory-path/filename.iso 'new_copied_link_location' --continue-at -Use a checksum utility such as sha256sum to verify the integrity of the image file after the download finishes:
$ sha256sum rhel-x.x-x86_64-dvd.iso `85a...46c rhel-x.x-x86_64-dvd.iso`Compare the output with reference checksums provided on the Red Hat Enterprise Linux Product Download web page.
- Resuming an interrupted download attempt
The following is an example of a
curlcommand for a partially downloaded ISO image:$ curl --output _rhel-x.x-x86_64-dvd.iso 'https://access.cdn.redhat.com//content/origin/files/sha256/85/85a...46c/rhel-x.x-x86_64-dvd.iso?_auth=141...963' --continue-at -
