#As a good security practice, SonarQuber Server is not advised to run sonar service as a root user, so create a new user called sonar user  and grant sudo access to manage nexus services as follows.
useradd sonar

visudo

sonar   ALL=(ALL)       NOPASSWD: ALL

Change the owner and group permissions to /opt/sonarqube/ directory.

su - sonar
cd /opt/sonarqube/bin/linux-x86-64/
