Lab 26: Installing VMware vCenter Server Components

vCenter server is ta centralised platform for managing all the VMware vSphere environments components like ESXi hosts, clusters, virtual machines, virtual machine templates, replication, high availability. It is a Centralised visibility, proactive management and extensibility for VMware vSphere from a single console.

The main purpose of the VMwere vCenter is to manage virtual machines and ESXi hosts centrally. vCenter server is a vSphere component which is mostly used in the large environment where there are many ESXi servers and dozens of virtual machines. The vCenter server is also accessed by vSphere client for management purpose.

VMwere vCenter can be installed windows operating system, and vCenter Server Appliance (VCSA) is the SUSE Linux based operating system. The components of the vCenter are Single Sign-On, vSphere Web Client, vCenter Inventory Service, and vCenter Server.

In this lab,  I will demonstrate how to install the vCenter 5.5 Single Sign-On components in the windows server 2012 R2.

The tasks of the lab 26: 

  • To install vCenter Single Sign-On
  • To install vSphere Web Client
  • To install vCenter Inventory Service
  • To install vCenter Server
  • To VMWare Update Manager

Install the vCenter Server Components:


  • Download VMware vCenter Server Software
  •  VMware vCenter Server VM with windows server 2012 R2 operating system
  • vCenter Server must be registered with the domain controller.
  • You may need adobe flash player to run vCenter Server onto the browser.
  • You may need to install the “.NET3.5 extensibility” during installation.

Step1: Double click VMware vCenter Server Software to install it. The software will begin to run with “simple install“. Simple install included vCenter Single-Sign on, VShphere Web Client, vCenter inventory server, and vCenter Server on same host or VM


Step for the task: To install vCenter Single Sign-on  Setup

It is a secure token exchange mechanism that allows various vSphere software components to communicate with each other with vCenter Single Sign-On authentication service in the VMware infrastructure platform instead of each component requires authenticating the users separately with a directory service like the Active directory.


Accept the End-User License Agreement


This step, You need to check the “simple install” prerequisites test that prerequisites must fulfil before installing begun; Otherwise, you will get the error in the middle of installation.


You need to setup domain name, user name, the password for administrator account for Single Sing-Up. This information will authenticate and authorised you when you will log in any other component of the vCenter Server.


Type an appropriate site name instead of default site name.



You can change the destination folder if you want. This is the folder where your application will be loaded after installation.


Steps for the task: To install vSphere Web Client

The vSphere Web Client enables you to connect to a vCenter Server system to manage an ESXi host through a browser.

Select the vSphere Web Client from WMware vCenter Server to continue installation.

Provide the information vSphere web client with vCenter Single Sign-On credentials.



You need to install certification to configure vSphere web client with the URL. Client “Install certificate”



Step for the task: To install vCenter Inventory Service





In this step, You have to give your “Fully Qualified Domain Name” (FQDN). The part will be your vCenter Server machine name and your domain controller name.

Note: Be careful in this step, don’t forward further installation until you verified FQDN matching with your local system name, which you recorded; otherwise, you will get an error when your system will working with inventory services.



vCenter JVM memory inventory size depends on how many VM you want to implement on ESXi host. In my case, I am doing it as the college project, I will create may be 3-5 VM in my ESXi host. Therefore, I chose small inventory size.

Step for the task: To install vCenter Server 

In this step, I will demonstrate the installing process of vCenter Server.

VMware vCenter Server allows for the management of multiple ESX servers and virtual machines (VMs) from different ESX servers through a single console application.






Now you need to install database system for your vCenter Server. Select the “Microsoft SQL Server 2008 Express instance”.









In this step, you will get vCenter Inventory Server URL to access your inventory system through the browser.













Step for the task: To VMWare Update Manager

Update Manager enables centralised, automated patch and version management for VMware vSphere and offers support for VMware ESX/ESXi hosts, virtual machines, and virtual appliances.

Select the “vSphere UpdateManager” fromVMware vCenter Client to run the installation56


Provide the VMware vCenter Server Information to the UpdateManager.  Update Manager requires network connectivity with VMware vCenter Server. Each installation of Update Manager must be registered with a single vCenter Server instance.Therefore, when vCenter Server component will be updated, it gets update automatically.5960.jpg61.jpg

Recommendation: Installing VMware vCenter Server Components are very easy and friendly. You just need to carefully read every step instruction to go next step.

VMware vSphere vCenter Single Sign-On

vCenter Single Sign On lets you add identity sources, manage default domains, configure a password policy, and edit the lockout policy. A collection of users and groups data are identity source.Data of the users and group are stored in a repository, such as Active Directory, LDAP, or a database that is internal to Single Sign On or local to an operating system.

It is an authentication broker and a security token exchange providing a more secure way of accessing your vSphere solutions. When logging in to vSphere you actually pass authentication to the vCenter Single Sign-On server which can be configured with multiple identity sources such as  Active Directory and OpenLDAP and on successful authentication, your username and password is exchanged for a security token which is then used to access the vSphere components like vCenter Server and vCenter Orchestrator.

Thank you 🙂
