我们是Sonar的新手，刚刚下载了v2.13.1并开始使用我们的项目。它很棒，直到它开始慢慢运行，我意识到这是因为我们仍在运行包含的Derby。我们在同一个盒子上运行MySQL Server 5.1（以及TeamCity CI），所以我按照步骤设置MySQL。
extras\database\mysql\create_database.sql来创建声纳用户并分配权限。我更新了conf\sonar.properties以包含：
sonar.jdbc.url: jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8
sonar.jdbc.driverClassName: com.mysql.jdbc.Driver
sonar.jdbc.validationQuery: select 1
我重新启动了Sonar服务器，并从日志中看到数据库表已创建，我可以通过浏览数据库来独立确认。
当我启动服务器时，我在日志中得到以下内容：
2012.02.07 13:50:58 INFO o.s.c.p.Database Create JDBC datasource
2012.02.07 13:51:01 INFO org.sonar.INFO Initializing Hibernate
2012.02.07 13:51:11 INFO org.sonar.INFO Start services...
当我运行我的TeamCity配置执行“mvn clean install”后跟“mvn sonar:sonar”目标（之前在Derby下工作）时，我们的构建成功完成，但Sonar死于以下信息：

后面的错误行提到端口1527，它被注释掉的Derby配置行引用。
[14:11:31] [ERROR] Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.0:sonar (default-cli) on project my-project: Can not execute Sonar: PicoLifecycleException: method 'public final org.sonar.core.persistence.DefaultDatabase org.sonar.core.persistence.DefaultDatabase.start()', instance 'org.sonar.batch.bootstrap.BatchDatabase@1d4d6a, java.lang.RuntimeException: wrapper: Fail to connect to database: Cannot create PoolableConnectionFactory (java.net.ConnectException : Error connecting to server localhost on port 1527 with message Connection refused: connect.) -> [Help 1]
如果我注释掉上面的sonar.jdbc行并恢复以下行，那么我们的“mvn clean install”和“mvn sonar:sonar”都会成功完成。
sonar.jdbc.url: jdbc:derby://localhost:152/sonar;create=true
sonar.jdbc.driverClassName: org.apache.derby.jdbc.ClientDriver
sonar.jdbc.validationQuery: values(1)
Maven目标的配置是否与Sonar服务器直接使用的配置不同？是否有明确的方法来确定连接哪个JDBC数据源？
答案 0 :(得分：7)
Sonar服务器和Maven客户端是单独配置的。
除非另有配置，否则Maven会自动假设Sonar在本地运行Derby数据库，解释您的错误。
Sonar documentation解释了Maven如何配置为支持MySQL。

昨天（2012年4月11日）我遇到了类似的问题 1）输入：
2）结果：
日志包含异常
Fail to connect to database: Cannot create PoolableConnectionFactory (java.net.ConnectException : Ошибка соединения с сервером localhost на порту 1527
3）可能的原因：
4）解决方案：
