Resolution

Satellite 6.7 or newer

Follow this documentation directly.

Satellite 6.6 or older:

  • Verify the correct proxy settings in /etc/rhsm/rhsm.conf on Satellite server :

    #http proxy server to use
proxy_hostname = proxyserver.com
# port for http proxy server
proxy_port = 80

  • Update the proxy details into foreman :

      # katello-installer --katello-proxy-url=http://proxyserver.com --katello-proxy-port=80

  OR 

  # satellite-installer --katello-proxy-url=http://proxyserver.com --katello-proxy-port=80 --katello-proxy-username redhat --katello-proxy-password xxxxx

  Where:
    --katello-proxy-password      Proxy password for authentication (default: nil)
    --katello-proxy-port               Port the proxy is running on (default: nil)
    --katello-proxy-url                  URL of the proxy server (default: nil)
    --katello-proxy-username      Proxy username for authentication (default: nil)

  • Check the below files are updated with the correct proxy details:

    # cat /etc/pulp/server/plugins.conf.d/yum_importer.json
# cat /etc/pulp/server/plugins.conf.d/puppet_importer.json
# cat /etc/pulp/server/plugins.conf.d/iso_importer.json
# cat /etc/foreman/plugins/katello.yaml

For more KB articles/solutions related to Red Hat Satellite 6.x Repository Issues, please refer to the Red Hat Satellite Consolidated Troubleshooting Article for Red Hat Satellite 6.x Repository Issues.

Root Cause

  • The proxy server configured in foreman does not match with rhsm.conf file.

    • Check the answer /etc/katello-installer/answers.katello-installer.yaml file on Satellite server:

          # vi /etc/katello-installer/answers.katello-installer.yaml

    proxy_url: "http://10.10.10.10"
    proxy_port: "80"

    • Compare the proxy server details with rhsm.conf file 

      # vi /etc/rhsm/rhsm.conf
proxy_hostname = proxyserver.com
# port for http proxy server
proxy_port = 80

    • Check the proxy value set for CDN 

      # vi /etc/foreman/plugins/katello.yaml
cdn_proxy:
host: http://10.10.10.10
port: 80

  • Check if yum command works from client . If yum works , it means, rhsm.conf proxy is working properly 

    # yum check-update
