Preflight checklist
There are some tasks that needs to be done before we can do the deployment of VCF.
Regenerate certificates
Out of the box, the ESXi servers have a default self signed certificates. After the hostname is set, the certificates needs to be regenerated.
On all ESXi servers
These commands needs to be run on all the ESXi servers using ssh.
rm -f /etc/vmware/ssl/rui.crt
rm -f /etc/vmware/ssl/rui.key
# Regenerate ESXi self-signed certificates
/sbin/generate-certificates
# Restart services
services.sh restart
# Verify hostd is running
/etc/init.d/hostd statusNote
This will take a few minutes.
ESXi Fingerprints
After the certificate has been generated, we need to get the fingerprints for the installer.
From the ESXi host
Run the following command on each ESXi host
openssl x509 -in /etc/vmware/ssl/rui.crt -fingerprint -sha256 -noout | sed 's/://g' | sed 's/SHA256 Fingerprint=//'Disable 10G check on vcf-installer
ssh to the VCF Installer and su - to root
ssh [email protected]
# su - to root
su -
# Edit the file
vim /etc/vmware/vcf/domainmanager/application.properties
# Add the following line in the end
enable.speed.of.physical.nics.validation=false
# Restart the SDDC Manager services
/opt/vmware/vcf/operationsmanager/scripts/cli/sddcmanager_restart_services.sh
You are about to restart all SDDC Manager services. Are you sure you would like to continue [y/n]? yNote
This will take a few minutes.
