Installing vCenter Server Appliance 6.5

VMware vCenter Server 6.5 has many new and innovative features. The installer has been overhauled, resulting in a new, modern look and feel. It is now supported on Microsoft Windows, macOS, and Linux operating systems (OSs) without the need for any plug-ins. With vSphere 6.5, the VMware vCenter Server Appliance has surpassed the Windows installable version. It offers the following exclusive features:
• Migration Tool
• Improved appliance management
• Native high availability
• Native backup and restore
There are also general improvements to vCenter Server 6.5, including the vSphere Web Client and the fully supported HTML5-based vSphere Client.

Today we are going to install the new vCenter Server Appliance 6.5.

First you must download the VMware VCSA 6.5 iso file from VMware site, after you login with your vmware account. Here you can find the link.

Second you need a running ESXi host reachable from your network and at least 4GB on your host and 20GB on a datastore.

Installation of VMware vCenter Server Appliance 6.5 (vCSA) is divided into 2 parts:

Stage 1: Deploy Appliance

Stage 2: Set Up vCenter Server Appliance

First we will deploy appliance on an esxi server on our network. Once you have downloaded the VCSA 6.5 ISO, mount on any machine in your network and browse to the iso folder and run installer:  vcsa-ui-installer\win32\installer.exe


When you have run the installer, you can see that you have several options, which are available in this new version 6.5 of vCSA.

  • Install: to run the VCSA installation (I choose this option)
  • Upgrade: if you want to upgrade an existing VCSA to 6.5 version
  • Migrate: to migrate a Windows vCenter Server to vCenter Server Appliance
  • Restore: to recover the VCSA from a previous backup


Next wizard shows as I mention above, there are two steps to deploy the VCSA. In the first step, we will deploy the appliance and in the second one, we will configure it. Click Next to continue and accept license agreement on next screen and click next again.


We have to choose a deployment type of vCenter Server Appliance. There are 2 different types of deployment:

– vCenter Server with an embedded Platform Services Controller – All services that are bundled with the Platform Services Controller are deployed together with the vCenter Server services on the same virtual machine or physical server.

– vCenter Server with an external Platform Services Controller – Only the vCenter Server services are deployed on the virtual machine or physical server. You must register such a vCenter Server instance with a Platform Services Controller instance that you previously deployed or installed.

We go with Embedded type and click Next.


Here we need to specify the target ESXi host details on which the appliance will be deployed. Click Next and in Certificate Warning  windows that will appear click Yes.


After that, we specify the name of the VCSA and the root password for the appliance itself.


In the next screen, you can choose the appliance size. Depending on your current virtual infrastructure decide with which appliance size you will go. You see, bigger that your environment is, more resources are needed for VCSA. I go with Tiny and click Next.


After that choose a datastore where the VM will be deployed and click on next. For more efficent use of datastore, I checked Enable Thin Disk Mode.


And then finally you have to configure the networking for appliance. You can choose either static or DHCP for IP assignment. Make sure to have record on DNS server with correct IP and FQDN name for VCSA and click Next.


To begin the appliance deployment, click on Finish in the below screen after you have checked all the above configuration made.


This step maybe last for about 10 minutes or less. During the deployment, you will see a progress bar indicated the current state of process.


After the deployment will finish, you will see a green ticket, if deployment was successfull. If so, click Continue with the stage 2 of the process.


In the stage 2, we will configure the appliance which just deployed. Click Next to continue with next steps.


Next specify some NTP server to synchronize the time. You can choose to enable or not the SSH access to the appliance. Click Next.


Here you need to specify the SSO information about new VCSA, login account, password and site name. Click Next to proceed.


Next you can accept to join the VMWare’s Customer Experience Improvement Program (CEIP) or not (optional). Click Next to be ready for setting up.


And last, click on Finish to run the all configuration made.


During the configuration, you should have a progress bar to inform you where you are in the process.

Once the configuration is finished and it was successfull, you should have the below screen. You can access your vCenter Server Appliance from url provided in the screen. Click close to exit the installer.


In web browser, open the VCSA using the  https://ip or fqdn:443/vsphere-client

In the vCenter Single Sign-On enter the administrator account and password you provided during the deployment and Login.


After a successfull login to your new vCenter Server 6.5 environment, you should see the screen below:


And that’s all for installing new vCenter Server Appliance 6.5.

Thanks for reading and share it !!!
