由于本教程，我正在尝试将Jenkins 2和SonarQube 6.7.3集成到centos 7上：
我安装和配置所有软件，如：java，PostgreSQL，SonarQube，......我真的很困惑如何正确启动声纳，以便能够在;;上通过http://localhost:9000/打开声纳仪表板，现在我可以＆＃39 ; t打开它是因为声纳服务未正确启动且 PID继续快速变化：
[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 ~]#
sonar can't be opened on FireFox
我通过以下命令启动并启用PostgreSQL：
[root@localhost ~]# systemctl start postgresql-9.6
[root@localhost ~]# systemctl enable postgresql-9.6
[root@localhost ~]# systemctl status postgresql-9.6
