Upgrade the first node in a vCenter Single Sign-On installation for high availability.
About this task
vCenter Server 5.5 supports connection between vCenter Server and vCenter Server components by IP address only if the IP address is IPv4-compliant. To connect to a vCenter Server system in an IPv6 environment, you must use the fully qualified domain name (FQDN) or host name of the vCenter Server. The best practice is to use the FQDN, which works in all cases, instead of the IP address, which can change if assigned by DHCP.
For more information about vCenter Single Sign-On, see How vCenter Single Sign-On Affects vCenter Server Upgrades and the vSphere Security documentation.
Review Prerequisites for the vCenter Server Upgrade.
- In the software installer directory, double-click the autorun.exe file to start the installer.
- Under Custom Install, select vCenter Single Sign-On, and click Install.
- Follow the prompts in the installation wizard to choose the installer language, and agree to the end user patent and license agreements.
- Enter the password for the vCenter Single Sign-On administrator account.
- Click Install.
The first high availability vCenter Single Sign-On node is upgraded.
After vCenter Single Sign-On is installed or upgraded, the following default identity sources and users are available:
All local operating system users. These users can be granted permissions to vCenter Server. If you are upgrading, those users who already have permissions keep those permissions.
Contains all users who have administrator access to the vCenter Single Sign-On server. Initially, only the user administrator is defined.
To add other identity sources, such as a native Active Directory (Integrated Windows Authentication) domain or an OpenLDAP directory service, see Add a vCenter Single Sign-On Identity Source.
