Activate a Datameer License Without UI Access

Problem

I need to activate a Datameer license, but UI is not available.

Solution

In case the Datameer UI is not available for some reason, there are alternative approaches to upload a license.

REST API

• Ensure that Datameer is up and running.
• Execute the following REST API call.
  
  curl -u <username>:<password> -X POST --form "file=@<license path>" http://<Datameer-server-address>:<port-number>/license/upload
  
  
• The call should return an updated license status. If successful, the expected response is VALID.
  
  

Direct license file upload

The current license is stored as file license in /<Datameer service user home folder>/.datameer/ on the Datameer server. The file license is a base64 encoded version of the license.lic file.

To convert the initial license.lic and copy it to the target folder, use the following command: 

base64 /<License file location>/<license>.lic | tr -d '\n' > /home/<Datameer service user>/.datameer/license

Please note that this command has been tested on CentOS and might have different syntax on another OS.

• Stop Datameer.
• Convert the .lic file and overwrite the license file with the above command.
• Start Datameer to let it pick up the updated license.
