I am currently upgrading from sonar 5.6.6 to 6.7.5 (LTS). I never changed ElasticSearch from the root user and did not have issues with Sonarqube starting up. I want to change ElasticSearch since this is not recommended to have it running as root. What is the simpliest way to do this. I was going to do a chown -R on the elasticsearch directory, but the problem with this is that new files won’t maintain ownership as the non superuser. Is there a better alternative approach to this?
Its interesting because Sonar starts up fine for me as root and I don’t see any issues in the logs. I tried to change the sonar.sh script and uncomment Run_AS_USER, however when trying to start up sonar it tells me unable to start sonar. I do not see any logs in the sonar directory either to see what the issue may be. I’m thinking it is a permissions issue. Are their any files that the RUN_AS_USER may change that I should check?
SonarQube 5.6.6 may indeed run fine as root. SonarQube 6.7.5 will not. You can check the upgrade notes (linked from the bottom of this page) if you feel compelled to identify the exact intermediate version that introduced the restriction.
