The default Heimdall server username is “admin” and the password is EITHER:
- “heimdall“; or
- In AWS and similar environments, the AWS instance ID.
If the password is not set to “heimdall” please see the server log (/var/log/heimdallserver.out.log or /opt/heimdall/log/heimdall.log) and look for a line such as:
2016-12-11 20:10:32,516 5153 [INFO] [http-nio-8087-exec-1] Initializing access control, user=admin, password=i-0aa1234a1a1a12abc
Advanced
The default username and password for a server can be controlled explicitly by creating a file /etc/heimdall.conf prior to the server being first run, and add the lines:
- hduser=<username>
- hdpassword=<password>
When the http query “http://169.254.169.254/latest/meta-data/instance-id” returns a value, this value is used as the default password if no configuration is set in the /etc/heimdall.conf. This will happen in AWS instances, and some other cloud environments. This value can be obtained with:
echo `curl -s http://169.254.169.254/latest/meta-data/instance-id`
In the event the passwords need to be deleted from a current configuration, the following steps can be used to delete the configured accounts:
- Open the file $heimdallhome/config/heimdall.conf (the default install directory is /opt/heimdall/)
- Remove the json array values for the “address” variable, i.e. replace:
“addresses”:[{“enabled”:true,”file”:”config/admin_1.conf”,”name”:”admin”,”version”:1}]
With
“addresses”:[]
Once saved, if all accounts are removed, then the default admin account will be re-initialized once the Heimdall server is restarted.
