After completing the configuration and preparation for the above articles, the next step is to directly configure to enable VCSA high availability.

Launch the vCenter HA configuration page

Log in to vsphere web client as an administrator

Navigate to the vCenter object in the listing through vsphere web client and select configure vCenter HA configuration

By launching the configuration vCenter HA wizard, you can see that there are both basic and advanced configuration modes seen above, and an error will be reported because the vCenter of this environment is not satisfied with being located on the ESXI that you manage or on the VC that is connected to the same PSC. In fact, the basic configuration is more than the advanced configuration. The system will automatically clone the active vCenter Server according to the set IP.

Select advanced configuration options

Next, configure the IP address (non-administrative IP) of the HA network of the passive node and witness node summarized by the HA model, and click next to detect and confirm.

Keep the page in the clone virtual machine page, and be careful not to click finish or cancel until the next step is completed; just keep the page

Clone the primary vCenter node

In the advanced configuration, we need to manually clone the active VCSA;. If the basic configuration options are met, the configuration content in this section will be completed automatically.

Select the main VCSA virtual machine, right-click and select clone

Specify the virtual machine name of the VCSA

Specify Cluster

Specify resource pool

Designated memory

Check "Power on this virtual machine after creation" and "customize using the Custom Wizard" in the client customization.

The computer name in the open client customization page ensures that it is the same as the host and the single user.

The same time zone as the master node is retained in the time zone setting, and the time zone of the master node of this environment is set to Asia / Shanghai.

Select Custom Settings in the network

You can see that there are two network cards on the VCSA. The network card 1 (that is, the management IP) is set to the same IP information as the main vCenter.

Set the network card 2 (that is, the HA network) and set the HA ip information corresponding to the page just now. Note that the gateway should be kept blank.

Specify DNS server information

You can choose to retain the custom specification

Confirm the custom specification click finish

Click finish on Clone Progress

Next, the system starts to clone the primary VCSA

After the cloning is completed, another one is cloned from the main VCSA according to the same process and method, and the difference is on the network card setting. On the witness node, because it does not participate in the actual work of vCenter Server, it only undertakes the cluster witness work. Therefore, the network card 1 is left empty and does not set up. The IP setting of Nic 2 is to be set to the IP of the HA network of the witness node specified in the wizard

Both virtual machines have been cloned and powered on

After both virtual machines are cloned and booted, go back to the vCenter HA configuration page and click finish.

After waiting for the vCenter HA configuration to be completed, you can see the cluster node status of vCenter HA, which has three nodes: active, passive, and witness.

You can see the replication status under vCenter HA by switching to the monitoring page.
