Chapter 13. Changing proxy settings

First option: Rerun the installer to update the global RHUI tools configuration and answers file:

rhui-installer --rerun --proxy-protocol <PROTOCOL> \
                       --proxy-hostname <HOSTNAME> \
                       --proxy-port <PORT> \
                       --proxy-username <USERNAME> \
                       --proxy-password <PASSWORD>

Second option: Create (or edit) the local overrides file, /root/.rhui/rhui-tools-custom.conf, so that it contains:

[proxy]
proxy_protocol: <PROTOCOL>
proxy_host: <HOSTNAME>
proxy_port: <PORT>
proxy_user: <USERNAME>
proxy_pass: <PASSWORD>

In either case, the parameters are as follows:

Make sure you have a list (or lists) of your repositories so that you can add them again. If you do not have such a list, you can use rhui-manager to generate a file with all your currently added Red Hat repositories.

To generate a list of Red Hat repositories, first create a raw list with one ID per line:

rhui-manager --noninteractive repo list --redhat_only --ids_only > /root/rawlist

Then create a YAML file with repositories. Start by creating a stub:

echo -e "name: all Red Hat repositories\nrepo_ids:" > /root/repo_list.yml

Next, append the repositories from the raw list as YAML list items:

sed "s/^/  - /" /root/rawlist >> /root/repo_list.yml

Delete all Red Hat repositories from your RHUI:

Use the text user interface, or delete them one by one on the command line. For the latter, you can use the raw list created earlier:

while read repo; do rhui-manager --noninteractive repo delete --repo_id $repo; done < /root/rawlist

When the repositories have been deleted, re-add them. They will be added with the new proxy settings (or with no proxy URL) this time. It is also necessary to re-synchronize the repositories. You can add and re-synchronize them in one step on the command line:

rhui-manager --noninteractive repo add_by_file --file /root/repo_list.yml --sync_now

Alternatively, use your own methods to synchronize the repositories, for example, in a specific order. Lastly, you can also simply wait for the synchronization to start automatically: in six hours, or in any other time defined as repo_sync_frequency in /etc/rhui/rhui-tools.conf.
