Instalei o SonarQube no CentOS e o serviço Sonar está ativo e em execução. No arquivo de configuração, a porta de uso está definida como 9000. Mas a interface do usuário do Sonar não pode ser acessada em localhost:9000
.
Este é o meu sonar.log:

Pela documentação
Além disso, certifique-se de reiniciar o serviço após fazer qualquer alteração na configuração.
