你能帮帮我吗？

此外，没有其他进程在端口9000上运行，而这正在发送给sonarqube

Answer 1

您的SonarQube配置为使用Postgresql数据库，但是根据此错误，您的服务器无法连接到此数据库：

Caused by: org.postgresql.util.PSQLException: Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

您应该检查sonar.jdbc.url属性。

Answer 2

您是否在sonar.properties中解除了这些行的注释？（senarqube_folder/conf/sonar.properties）

 sonar.jdbc.username= 
 sonar.jdbc.password=
 sonar.jdbc.url=jdbc:postgresql://localhost/sonar

并将用户名，密码设置为您为角色设置的用户名和密码？例如：

 sonar.jdbc.username=sonar 
 sonar.jdbc.password=sonar

在我创建角色时没有设置角色的权限之前我遇到了另一个问题，在重新启动我的电脑后我无法连接到数据库。创建新角色后，我必须右键单击新角色并在pgAdmin中添加权限。有时我也不得不手动连接到服务器。

打开pgAdmin
右键单击服务器并连接

SonarQube启动然后停止
