Unable to start Sonar as a service on linux machine

I’ve Linux Red Hat Enterprise Linux Server 7.5 (Maipo) and downloaded SonarQube 7.4 and went to its directory - /home/oracle/sonar/sonarqube-7.4/bin/linux-x86-64 and run
./sonar.sh start (based on https://docs.sonarqube.org/latest/setup/operate-server/) but it results into -

Starting SonarQube…
Failed to start SonarQube.

in sonar.log, saw following error -

Launching a JVM...
Unable to start JVM: Permission denied (13)
JVM exited while loading the application.
JVM Restarts disabled.  Shutting down.
<-- Wrapper Stopped

Please help what is wrong here.

Hi,

Check the server logs and come back to us with the errors you see there if the problem’s not already obvious at that point.
