    • sonar.jdbc.url: The JDBC URL for your database.
    • sonar.jdbc.username: The username for your database.
    • sonar.jdbc.password: The password for your database.

    For example, if you're using PostgreSQL, you might configure these properties like this:

    sonar.jdbc.url=jdbc:postgresql://localhost:5432/sonarqube
sonar.jdbc.username=sonar
sonar.jdbc.password=sonar

  4. Save the Configuration File: Save the changes to the sonar.properties file.

Step 4: Start SonarQube

With SonarQube configured, you're now ready to start the server. Here’s how:

  1. Open a Command Prompt: Open a command prompt window as an administrator. You can do this by searching for “cmd” in the Start menu, right-clicking on “Command Prompt,” and selecting “Run as administrator.”

  2. Navigate to the Bin Directory: Use the cd command to navigate to the bin directory inside the extracted SonarQube folder. For example, if you extracted SonarQube to C:\sonarqube, you would use the following command:

    cd C:\sonarqube\bin\windows-x86-64

    Note: The windows-x86-64 directory may be different depending on your system architecture. Make sure to choose the correct directory.

  3. Start SonarQube: Run the StartSonar.bat file to start the SonarQube server. This will start the SonarQube server in the background.

    StartSonar.bat
