Comprehensive Guide to implement vRealize Automation 8.x Clustered environment

In my last post, I've discussed how one would deploy a vIDM cluster. Now let's see what does one need to deploy a vRealize Automation 8.x clustered instance


Load Balancer Configuration


I'm using NSX-V as my Load Balancer version 6.4.7


Application Profile

Service Monitor

Pools



Virtual Servers




One more thing to remember, create an application rule and then map it to workspace one virtual server configuration as shown below, why is this needed, I'll explain this later






Once all of these are done, you are pretty much done with the load balancer configuration needed to deploy a distributed instance of vRealize Automation 8.x


Now let's go to the next phase


Configure Certificate and Generate vRA 8.x environment creation request


As a first step, enter all details needed to generate a certificate.

Remember, I am using a default certificate generated by vRLCM so that I can replace it with a CA-signed certificate later






Once the certificate is generated, then create a new vRA environment




Once the vRA 8.1 Cluster option is selected, we will click next and then accept EULA




After EULA, we have to add/apply a license


Enter Certificate information

Enter Infrastructure information

Enter Network Information



Perform PreCheck. All Validations must be successful



I have attached the precheck report here. Download and review if you would like to

Review all the details and then submit a request


Stages in vRA Distributed Installation


We have 11 stages in total for a distributed vRA deployment


Stage 1: validateenvironmentdata



Stage 2: infraprevalidation




Stage 3: vravaprevalidation


Stage 4: vravainstall



Stage 5: vravajoincluster



Stage 6: vravajoincluster




Stage 7: vravasetlicense




Stage 8: vravainstallcertificate



Stage 9: vravainitializecluster


During this phase, I did encounter issues at a stage where it does vravainitialize



Basically, at a point where it was trying to initialize client secrets, it was failing prematurely



This is the reason we created Application rules while trying to configure the Load Balancer.


Once this was configured, we did retry the installation again


After ensuring the application rule is present you can now see the stage is has been completed successfully


Stage 10: environmentupdate


Stage 11: notificationschedules



vRealize Automation 8.x Clustered Deployment is now completed




Logs to monitor during deployment

vRA Appliances : /var/log/deploy.log
vRLCM Appliance : /var/log/vrlcm/vmware_vrlcm.log


Post Deployment Checks


Ensure the status of all pool members is shown as UP

This is how your LCM environment pane would look

Explore your vRA environment


Access your vRA Load Balancer and it responds back with the login page




In the next few blogs, we shall explore the vRA 8.x configuration and using it with a few advanced blueprints
