2.2. Registering from the Command Line
The simplest way to register a machine is to pass the
register command 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.
The
register options are listed in Table 2, “register Options”.
Example 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 2. Automatically Subscribing While Registering
The
register command has an option, --auto-attach, 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 --auto-attach
This is the same behavior as when registering with the default settings in the Subscription Manager UI.
Table 2. register Options
| Options | Description | Required |
|---|---|---|
| --username=name | Gives the content server user account name. | Required |
| --password=password | Gives the password for the user account. | Required |
| --serverurl=hostname | Gives the hostname of the subscription service to use. The default is for Customer Portal Subscription Management, subscription.rhn.redhat.com. If this option is not used, the system is registered with Customer Portal Subscription Management. | Required for Subscription Asset Manager or Satellite 6 |
| --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.

| --servicelevel=None|Standard|Premium | Sets the service level to use for subscriptions on that machine. This is only used with the --auto-attach option. | Optional |
| --release=NUMBER | Sets the operating system minor release to use for subscriptions for the system. Products and updates are limited to that specific minor release version. This is used only used with the --auto-attach option. | Optional |
