It is possible to change the domain names of the various AEN nodes by updating the configuration files.
To edit the information for all of the data centers that you are changing the base domain name for:
Go to the Site Admin section of the Admin Settings page.
In the Data Centers section, click the Edit button.
Make any necessary updates.
This must include the service port if it is different from the default—80 for HTTP and 443 for HTTPS.
In the Enterprise Resources sub-section of the Providers section, edit each compute node that has a changed domain name.
These URLs should include the protocol, hostname and port.
After the configuration files are updated, the associated nodes need to be restarted.
sudo service wakari-compute restart
