Sonar setup with MySql

Question

Iam trying to change the sonar Qube 5.5 default database to Mysql.But it is still connecting to default H2 DB.

Configuration as below.

I have run the below scripts in Mysql DB

# Create SonarQube database and user.
#
# Command: mysql -u root -p < create_database.sql
#

    CREATE DATABASE sonar CHARACTER SET utf8 COLLATE utf8_general_ci;

    CREATE USER 'sonar' IDENTIFIED BY 'sonar';
    GRANT ALL ON sonar.* TO 'sonar'@'%' IDENTIFIED BY 'sonar';
    GRANT ALL ON sonar.* TO 'sonar'@'localhost' IDENTIFIED BY 'sonar';
    FLUSH PRIVILEGES;

uncommented the sonar.jdbc.url for Mysql,Iam not able to see the configuration for H2 DB to comment it.

  # Property values can:                                                                                                                               
    # - reference an environment variable, for example sonar.jdbc.url= ${env:SONAR_JDBC_URL}

Then I restarted the server from Administration->system -> Systeminfo.

After restart using cmd line getting this error:

Answer 1

You appear to have made the correct configuration changes, but the in-UI restart you did is not a "full" restart. Do a restart from the command line and your instance should connect to your configured database.
