Create or upgrade the first vCenter Single Sign-On server for a multisite vCenter Single Sign-On installation.


  1. In the software installer directory, double-click the autorun.exe file to start the installer.
  2. Under Custom Install, select vCenter Single Sign-On, and click Install.
  3. Follow the prompts in the installation wizard to choose the installer language, and agree to the end user patent and license agreements.
  4. If you are installing a new instance of vCenter Single Sign-On , proceed to Step 5. If you are upgrading an existing installation of vCenter Single Sign-On , take the following steps:
    1. Enter the password for the vCenter Single Sign-On administrator account.
    2. Proceed to Step 8.
  5. Accept or change the HTTPS port for vCenter Single Sign-On.
  6. Select the deployment mode Standalone vCenter Single Sign-On Server.
  7. Set the password for the vCenter Single Sign-On administrator account.

    This is the password for the user administrator@vsphere.local. vsphere.local is a new domain that is created by vCenter Single Sign-On. After installation, you can log in to vCenter Single Sign-On and in to vCenter Server as adminstrator@vsphere.local.

    By default, the password must have at least eight characters, at least one lowercase character, one uppercase character, one number, and one special character. See the vSphere Security documentation for information about changing the password policy. The following characters are not supported in passwords: non-ASCII characters, semicolon (;), double quotation mark ("), single quotation mark ('), circumflex (^), and backslash (\).

  8. Review the installation options and click Install.


The first vCenter Single Sign-On multisite server is installed or 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.
