在RHEL系统中注册和使用subscription是两个过程：

NOTE: With Red Hat Subscription-Manager, registration and utilization of a subscription is actually a two-part process. First register a system, then apply a subscription.

可以使用下面命令一次完成两个过程：

# subscription-manager register --username <username> --password <password> --auto-attach

在我的RHEL 7.2系统上执行上述命令：

# subscription-manager register --username=xxxx --password=xxxx --auto-attach
Registering to: subscription.rhn.redhat.com:443/subscription
The system has been registered with ID: 333486bb-xxxxxx

Installed Product Current Status:
Product Name: Red Hat Enterprise Linux Server
Status:       Subscribed

然后检查状态：

# subscription-manager list

+-------------------------------------------+
    Installed Product Status
+-------------------------------------------+
Product Name:   Red Hat Enterprise Linux Server
Product ID:     69
Version:        7.2
Arch:           x86_64
Status:         Subscribed
Status Details:

接下来就可以使用“yum install”，“yum update”等命令安装和更新软件了，非常方便。
