in the topic vCenter Server Hardware Requirements.
12 Enter the information to register vCenter Server with vCenter Single Sign-On.
The vCenter Single Sign-On administrator user name is [e-mail], and the password
must match the password you entered when you installed vCenter Single Sign-On. The Lookup Service
URL takes the form https://SSO_host_FQDN_or_IP:7444/lookupservice/sdk, where 7444 is the default
vCenter Single Sign-On HTTPS port number. Your entry should match the entry you made when you
installed vCenter Single Sign-On. If you entered a different port number when you installed vCenter
Single Sign-On, use that port number.
NOTE If you installed vCenter Single Sign-On in a vCenter Server Appliance, you can enter the vCenter
Single Sign-On administrator user as root@localos. In this case, the password is the root password of the
vCenter Server Appliance. The Lookup Service URL takes the form
https://vCenter_Appliance_IP_or_host_name:{7444}/lookupservice/sdk.
13 Enter the Inventory Service URL.
The Inventory Service URL takes the form https://Inventory_Service_host_FQDN_or_IP:10443. 10443 is
the default Inventory Service HTTPS port number. If you entered a different port number when you
installed Inventory Service, use that port number here.
