      One-liner Command

      subscription-manager config --server.proxy_hostname=proxy.example.com --server.proxy_port=8080 --server.proxy_user=admin --server.proxy_password=secret

      Alternatively, proxy information can be added into configuration

      /etc/rhsm/rhsm.conf:

      # an http proxy server to use
proxy_hostname =

# port for http proxy server
proxy_port =

# user name for authenticating to an http proxy, if needed
proxy_user =

# password for basic http proxy auth, if needed
proxy_password =
      Testing the connectivity to RHN

      Without Proxy

      curl -v https://subscription.rhn.redhat.com/subscription/ --cacert /etc/rhsm/ca/redhat-uep.pem

      With Proxy

      curl -v --proxy-user user:password --proxy proxy.example.com:8080 https://subscription.rhn.redhat.com/subscription/ --cacert /etc/rhsm/ca/redhat-uep.pem

curl -v --proxy-user user:password --proxy proxy.example.com:8080 https://subscription.rhsm.redhat.com/ --cacert /etc/rhsm/ca/redhat-uep.pem

      FAQ

      Registering to: subscription.rhsm.redhat.com:443/subscription
      Network error, unable to connect to server. Please see /var/log/rhsm/rhsm.log for more information.

      Solution: Check the firewall by following the instructions below.

      • subscription.rhn.redhat.com:443 [https] AND subscription.rhsm.redhat.com:443 [https] (This is the new default address in newer versions of RHEL 7)
      • cdn.redhat.com:443 [https]
      • *.akamaiedge.net:443 [https] OR *.akamaitechnologies.com:443 [https]

      It is not recommended to specify the IP addresses because the packages are distributed through the Akamai network and the IP addresses are subject to change. However, if your firewall is unable to use host name filtering, Red Hat provides a pool of IP addresses that should provide CDN delivery.

      Q: subscription-manager attach --auto

      Installed Product Current Status:
      Product Name: Red Hat Enterprise Linux for x86_64
      Status: Not Subscribed

      Solution:

      1. 登入 https://access.redhat.com/，確定帳戶裡有可用的訂閱服務。
      2. 如果是免費版 RedHat Developer 帳號，在訂閱清單裡如果沒有看到 Red Hat Developer Subscription for Individuals 這一項，請先登入 https://developers.redhat.com/ 然後再確認一次。  注意: 免費版個人授權需要每年手動更新一次有效期。
      3. 執行 subscription-manager refresh

      This system is registered to Red Hat Subscription Management, but is not receiving updates. You can use subscription-manager to assign subscriptions.

      Solution:

      subscription-manager attach --auto
