Sonar fails to connect to database

问题:

I am using the following software:

• Sonar 3.4.1
• Mysql 5.1
• Maven 2.2.1
• Tomcat 7

I have a pom.xml file which I am trying to execute with Sonar but getting the follwing error.

[INFO] Building asgard-bpm [INFO] task-segment: [sonar:sonar] (aggregator-style) [INFO] ----------------------------------------------------------------------- [INFO] [sonar:sonar {execution: default-cli}] [INFO] Sonar host: http://{host:8080}/sonar [INFO] Sonar version: 3.4.1 [INFO] Execute: org.codehaus.sonar:sonar-maven-plugin:3.4.1:sonar [INFO] [sonar:sonar {execution: default-sonar}] [INFO] [14:34:54.474] Load project settings [INFO] [14:34:54.552] Install plugins [INFO] [14:34:56.674] Apply project exclusions [INFO] [14:34:56.674] Install JDBC driver [WARN] [14:34:56.736] H2 database should be used for evaluation purpose only [INFO] [14:34:56.736] Create JDBC datasource for jdbc:h2:tcp://host/sonar [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Can not execute Sonar  Embedded error: Fail to connect to database Connection refused: connect 

I have created a user in the DB with the username as 'sonar' and password as 'sonarsonar'.

Created schema named 'sonar' and granted all privileges also.

BELOW IS THE PROPERTIES SET IN THE SONAR.properties file.

sonar.web.host:                           {127.0.0.1} sonar.web.port:                           80 sonar.web.context:                        /   sonar.jdbc.username:                       sonar sonar.jdbc.password:                       sonarsonar  sonar.jdbc.url:                                      {jdbc:mysql://host:3306/sonaruseUnicode=true&characterEncoding=utf8} sonar.jdbc.driverClassName:                com.mysql.jdbc.Driver sonar.jdbc.validationQuery:                select 1 

Can someone please tell me how to resolve this error.

回答1:

Your Sonar is not connected to your database. Check your <.m2/settings.xml> file. You need to change the < sonar.jdbc.url > under the properties :

<!-- H2 - Default DB --> <!-- <sonar.jdbc.url>        jdbc:h2:tcp://localhost:9092/sonar      </sonar.jdbc.url> --> <!-- MySQL DB -->     <sonar.jdbc.url>       jdbc:mysql://localhost:3306/sonar?useUnicode=true&amp;characterEncoding=utf8     </sonar.jdbc.url> 

Also, look at this answer : https://stackoverflow.com/questions/17102025/sonar-not-connecting-to-mysql-db

回答2:

Configure "sonar-runner.properties" to connect to MySQL Database.

Try uncommenting this lines:

sonar.jdbc.url=jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8 sonar.jdbc.username=sonar sonar.jdbc.password=sonar sonar.sourceEncoding=UTF-8
