subscription-manager register to CentOS 7
Someone can tell how to register this System CentOS 7 using the subscription-manager. Because, I cannot buy a Red Hat System, any packages that I installed in the System yum is warning that: this System is not registered with an entitlement server. You can use subscription-manager to register.
So, I have tried the command subscription-manager register with all its menu options with Red Hat web site, but still not registering. Consequently, most the Labs classes of all coursers involving Network, Bind, DNS, HTTP... that I am doing coming out failed results.
Please, I appreciate your wizard...
