15.2.2. Registering from the Command Line
The simplest way to register a machine is to pass the
registercommand with the user account information required to authenticate to Customer Portal Subscription Management. When the system is successfully authenticated, it echoes back the newly-assigned system inventory ID and the user account name which registered it.
registeroptions are listed in Table 15.2, “register Options”.
Example 15.1. Registering a System to the Customer Portal
[root@server1 ~]# subscription-manager register --username admin-example --password secret The system has been registered with id: 7d133d55-876f-4f47-83eb-0ee931cb0a97
Example 15.2. Automatically Subscribing While Registering
registercommand has an option,
--autosubscribe, which allows the system to be registered to the subscription service and immediately attaches the subscription which best matches the system's architecture, in a single step.
[root@server1 ~]# subscription-manager register --username admin-example --password secret
This is the same behavior as when registering with the default settings in the Subscription Manager UI.
Example 15.3. Registering a System with Subscription Asset Manager
With Subscription Asset Managr or CloudForms System Engine, an account can have multiple, independent subdivisions called organizationst is required that you specify which organization (essentially an independent group or unit within the main account) to join the system to. This is done by using the
--orgoption in addition to the username and password. The given user must also have the access permissions to add systems to that organization.
To register with a subscription service other than Customer Portal Subscription Management, several additional options must be used to identify the environment and organizational divisions that the system is being registered to:
- The username and password for the user account withint the subscription service itself
--serverurlto give the hostname of the subscription service
--baseurlto give the hostname of the content delivery service (for CloudForms System Engine only)
--orgto give the name of the organization under which to register the system
--environmentto give the name of an environment (group) within the organization to which to add the system; this is optional, since a default environment is set for any organizationA system can only be added to an environment during registration.
[root@server1 ~]# subscription-manager register --username=admin-example --password=secret
--org="IT Department" --environment="dev" --serverurl=sam-server.example.comThe system has been registered with id: 7d133d55-876f-4f47-83eb-0ee931cb0a97
If the system is in a multi-org environment and no organization is given, the
registercommand returns a Remote Server error.

|--baseurl=URL||Gives the hostname of the content delivery server to use to receive updates. Both Customer Portal Subscription Management and Subscription Asset Manager use Red Hat's hosted content delivery services, with the URL https://cdn.redhat.com. Since CloudForms System Engine hosts its own content, the URL must be used for systems registered with System Engine.||Required for CloudForms System Engine|
|--org=name||Gives the organization to which to join the system.||Required, except for hosted environments|
|--environment=name||Registers the system to an environment within an organization.||Optional|
|--name=machine_name||Sets the name of the system to register. This defaults to be the same as the hostname.||Optional|
|--autosubscribe||Automatically ataches the best-matched compatible subscription. This is good for automated setup operations, since the system can be configured in a single step.||Optional|
