it looks like there is something already running on port 9001, which is the internal port that sonarqube is trying to start elasticsearch on. please clear up this port and try again
the other option you have if you can not clear up this port, you can configure another one with the property sonar.search.port in your conf/sonar.properties file.
Hi @Tobias_Trabelsi ,
Thank you for your quick response!
I changed as proposed the port of sonar.search.port as well I changed also sonar.web.port.
Now SonarQube is coming up.
Thank you, Florian
