error reason: elasticsearch cannot be run directly by root user due to security problems

Solution: liunx creates a new user, sonaruser, and runs sonar using this user

The steps are as follows:

Create user
$addUser sonaruser
create password for user
$passwd sonaruser
enter password twice,
modify the directory and user group of sonar as sonaruser
$chown – R sonaruser: sonaruser sonarqube-6.7.2
Restart sonar
$./sonar.sh start
create password for user
enter password twice,
Modify the directory and user group of sonar as sonaruser
Restart sonar
