Я не могу запустить SonarQube в CENTOS 7, потому что PID постоянно меняются

Question

Я пытаюсь интегрировать Jenkins 2 и SonarQube 6.7.3 в centos 7 из-за этого урока:

https://www.youtube.com/watch?v=osc0j_Z1x0w

Я устанавливаю и настраиваю все программное обеспечение, такое как: java, PostgreSQL, SonarQube, ... Я действительно запутался, как правильно запустить сонар, чтобы иметь возможность открыть панель гидролокатора на Firefox с помощью http://localhost:9000/, теперь я не могу открыть его потому что служба эхолота не запустилась правильно и PID продолжает быстро меняться :

[root@localhost ~]# service sonar status
SonarQube is running (36211).
[root@localhost ~]# service sonar status
SonarQube is not running.
[root@localhost ~]# service sonar status
SonarQube is running (36602).
[root@localhost ~]# service sonar status
SonarQube is running (36602).
[root@localhost ~]# service sonar status
SonarQube is not running.
[root@localhost ~]# service sonar status
SonarQube is running (36993).
[root@localhost ~]# service sonar status
SonarQube is running (36993).
[root@localhost ~]# 

сонар не может быть открыт в FireFox

Я запускаю и включаю PostgreSQL с помощью следующих команд:

[root@localhost ~]# systemctl start postgresql-9.6
[root@localhost ~]# systemctl enable postgresql-9.6
[root@localhost ~]# systemctl status postgresql-9.6

при повторном запуске команды systemctl status postgresql-9.6 вывод такой же, как при последнем запуске с Main PID: 1288 (postmaster):

но когда я запускаю и запускаю гидролокатор, выходы отличаются, и основной ПИД продолжает быстро меняться:
