Can not run elasticsearch as root sonarqube Error - SonarQube Elasticsearch do not run as root

When you tried to configure SonarQube, you may experience the below error:

2018.10.15 17:32:13 ERROR es[][o.e.b.Bootstrap] Exception
java.lang.RuntimeException: can not run elasticsearch as root

at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:106) 

SonarQube does not support being run as root user, so we need to create regular user like sonar and give privilege to that use.

Fix for the above issue:
create a user called sonar by executing below command:
sudo useradd sonar

sudo chown -R sonar:sonar sonar-install-folder/

Edit the sonar.sh start script and change the #RUN_AS_USER to be RUN_AS_USER=sonar

sudo vi /opt/sonarqube/bin/linux-x86-64/sonar.sh

Change 
RUN_AS_USER=sonar

now start the server 

sudo sh /opt/sonarqube/bin/linux-x86-64/sonar.sh start

This should fix that issue.
