Automating VCSA 5.1 (vCenter Server Appliance) Configurations

If you have seen my previous article on Automating VCSA (vCenter Server Appliance) 5.0, you will notice the existing script will not work on latest VCSA 5.1, without a minor tweak. The reason for this is due to the new vCenter SSO (Single Sign-On) configuration that is now part of the initial setup.

Note: If you would like to learn more about the new vCenter SSO, I would recommend you take a look at the What's New vCenter Server 5.1 whitepaper.

Luckily, the change is quite simple and in the example below, you will be configuring vCenter Server SSO to run in the embedded mode on the VCSA. I have also enhanced the script to include the joining of an Active Directory domain if you wish to have the VCSA backed by AD.

Disclaimer: This is for educational purposes only, this is not officially supported by VMware. Please test this in a development environment before using it on actual systems.

Here is a script with the minimal commands needed for running an embedded configuration:

#!/bin/bash

# User Configurations
JOIN_AD=0
AD_DOMAIN=primp-industries.com
AD_USER=administrator
AD_PASS=mysupersecurepassword
VCENTER_HOSTNAME=vcenter51-1.primp-industries.com

## DO NOT EDIT BEYOND HERE ##

echo "Accepting EULA ..."
/usr/sbin/vpxd_servicecfg eula accept

if [ ${JOIN_AD} -eq 1 ]; then
        echo "Configuring vCenter hostname ..."
        SHORTHOSTNAME=$(echo ${VCENTER_HOSTNAME} |  cut -d. -f1)
        /bin/hostname ${VCENTER_HOSTNAME}
        echo ${VCENTER_HOSTNAME} > /etc/HOSTNAME
        sed -i "s/localhost.localdom/${VCENTER_HOSTNAME}/g" /etc/hosts
        sed -i "s/localhost/${SHORTHOSTNAME}/g" /etc/hosts

        echo "Configuring Active Directory ..."
        /usr/sbin/vpxd_servicecfg ad write "${AD_USER}" "${AD_PASS}" ${AD_DOMAIN}
fi

echo "Configuring Embedded DB ..."
/usr/sbin/vpxd_servicecfg db write embedded

echo "Configuring SSO..."
/usr/sbin/vpxd_servicecfg sso write embedded

echo "Starting VCSA ..."
/usr/sbin/vpxd_servicecfg service start

Note: By default the script will not join an AD domain, you will need to change the JOIN_AD variable to 1 and ensure you specify all the Active Directory configurations including the FQDN of your vCenter Server as this is required for properly join your VCSA to your AD domain. If you choose to join an AD domain, make sure you have proper forward/reverse DNS configured on the VCSA and you will also need to reboot the VCSA for the changes to take effect.

To run the script remotely (you do not need to copy it to VCSA), use the following command:

# ssh root@[vcsa-ip] < configureVCSA.sh

You can now quickly deploy and configure your VCSA in just minutes versus spending 5-10 minutes clicking around and waiting for the web interface. Once you have tried this script, you will never go back to manually configuring the VCSA using the web interface!
