Replacing Self-Signed Certificates with Certificates Provided by an
Authority
If you installed vRealize Automation with self-signed certicates, you might want to replace them with
certicates provided by a certicate authority before deploying to production.
For more information about updating certicates, see Managing vRealize Automation.
Change the Master vRealize Automation Appliance Host Name
When maintaining an environment or network, you might need to assign a dierent host name to an
existing master vRealize Automation appliance.
In a high availability cluster of vRealize Automation appliances, follow these steps to change the host name
of the primary, or master, vRealize Automation appliance node.
Procedure
1 In DNS, create an additional record with the new master host name.
Do not remove the existing DNS record with the old host name yet.
2 Wait for DNS replication and zone distribution to occur.
3 From a console session as root on the master vRealize Automation appliance, run the following script.
/usr/lib/vcac/tools/change-hostname/changeHostName-master.sh new-master-hostname
4 Log in as root to the master vRealize Automation appliance management interface.
hps://vrealize-automation-appliance-FQDN:5480
5 Click Network > Address.
6 In the Hostname text box, enter the new master host name, and click Save .
7 From a console session as root, update the HAProxy conguration with the new master host name.
On all vRealize Automation appliances in the cluster, including master and replicas, use a text editor to
replace the old master host name throughout the les in the following directory.
/etc/haproxy/conf.d
8 Restart the master vRealize Automation appliance.
9 Restart replica vRealize Automation appliances, one at a time.
10 Log in as root to the master vRealize Automation appliance management interface.
11 Click vRA  > Database.
12 Reset any replica nodes that show a Status of N/A.
13 Verify that the Sync State is correct for database replication on each vRealize Automation appliance
node.
14 Click vRA  > Cluster.
15 Use Join Cluster to re-join each replica node to the cluster.
