So in Previous post i tried to explain what problem VMware solving with vCAv , now let’s get in to the installing of the components , there are two ways to install vCAv either using automated way or manually running few commands on vCAv appliance which will automatically install and configure stuff , this we can call semi automated and in next few posts i will be installing is using semi automated way as this gives me more comfort around understanding of what component is getting installed and integrate with whom…..

So lets get into the installation mode and first thing we need few Linux VM for

Cassandra	01 Nodes
RabbitMQ	01 Nodes
Cloud Proxy	02 Nodes

Since this is Demo environment , so i am not considering HA for any VMs.So first lets create a Cent OS VM with all the required pre-requisite installed on this and then template it , which will help us in saving considerable amount of time. same approach can be taken to your production deployment with customisation specification.

For this Demo , i am creating a new Linux VM based on CentOS-7-x86_64-Minimal-1804.iso and install the OS, Once OS installation is completed, Connect to the VM with SSH and first update yum:

#yum update yum and Reboot the guest OS.

Install the packages required by vCD.

#yum install alsa-lib bash chkconfig coreutils findutils glibc grep initscripts krb5-libs libgcc libICE libSM libstdc++ libX11 libXau libXdmcp libXext libXi libXt libXtst module-init-tools net-tools pciutils procps redhat-lsb sed tar wget which

I would suggest to install NTP to keep the VM clock in sync:

#yum install ntp

Configure ntp servers ,using VI, change the lines beginning with server to NTP servers. All components connecting to vCD should share the same NTP servers for accurate timekeeping:

#vi /etc/ntp.conf

Start the ntpd service

#systemctl start ntpd
#systemctl enable ntpd

Check ntpd is syncing to correct ntp servers using – #ntpq -p

There are lots of features depend on DNS , so i would suggest to install DNS bind utilities and verify that VM is able to resolve DNS queries.

#yum install bind-utils (to install nslookup)
#nslookup VMNAME
#nslookup VMNAME.DOMAIN.COM
#nslookup 192.168.110.1

For this lab environment, I turn off selinux as well as firewall, while in production deployment please choose correct configuration.

Go to selinux file and edit – #vi /etc/sysconfig/selinux and change SELINUX=enforcing to “SELINUX=disabled”.

To disable firewalld, run the following command as root: #systemctl disable firewalld and stop firewalld, run the following command as root: #systemctl stop firewalld

Install VMware tools , reboot the VM to takes effect all the above changes. now we are done with OS configuration , shutdown the VM and Change the VM as template and deploy 7 VMs from this template. while i am deploying These external VMs, also we need to deploy vCAv Appliance. download the appliance from here. and deploy the appliance by following below steps:

Choose OVF
