Installing SonarQube on CentOS 7

SonarQube is an open-source platform for continuous code quality inspection that helps to identify bugs, vulnerabilities, and maintainability issues in your codebase. By analyzing source code and providing detailed reports, SonarQube helps development teams improve code quality and maintain high standards.

Installation Steps

First, update your CentOS 7 system packages:

SonarQube requires Java to run. Install the JDK:

Download the latest version of SonarQube:

Create a new system unit file for SonarQube:

Create a new system user to run SonarQube:

Change the ownership of the SonarQube installation directory:

Start the SonarQube service and enable it to start on boot:

After starting the service, you can access the SonarQube web interface by navigating to http://your_server_ip_or_domain:9000 in your web browser. This will launch the SonarQube dashboard where you can configure projects and perform code analysis.

1. Update System Packages
2. sudo yum update -y
3. Install Java Development Kit (JDK)
4. sudo yum install java-1.8.0-openjdk-devel -y
5. Download and Configure SonarQube
6. wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-8.9.0.43852.zip

   Unzip the downloaded file:

   unzip sonarqube-8.9.0.43852.zip

   Move the extracted folder to the desired location:

   sudo mv sonarqube-8.9.0.43852 /opt/sonarqube
7. Configure SonarQube as a Systemd Service
8. sudo vi /etc/systemd/system/sonar.service

   Add the following configuration:

   [Unit]
Description=SonarQube service
After=syslog.target network.target

[Service]
Type=forking
ExecStart=/opt/sonarqube/bin/linux-x86-64/sonar.sh start
ExecStop=/opt/sonarqube/bin/linux-x86-64/sonar.sh stop
User=sonarqube
Group=sonarqube
Restart=always
LimitNOFILE=131072
LimitNPROC=8192

[Install]
WantedBy=multi-user.target

   Save and close the file.

9. Create a SonarQube System User
10. sudo useradd -r -s /bin/false sonarqube
11. Set File Permissions
12. sudo chown -R sonarqube:sonarqube /opt/sonarqube

    Ensure that other users cannot access the SonarQube installation directory:

    sudo chmod -R 775 /opt/sonarqube
13. Start and Enable the SonarQube Service
14. sudo systemctl start sonar
sudo systemctl enable sonar
15. Accessing SonarQube Web Interface

Congratulations! You have successfully installed SonarQube on CentOS 7. You can now start using SonarQube to analyze and improve your code quality.
