Step 1: Update Your System
First, update all packages to the latest versions:
sudo apt update && sudo apt upgrade -y
Step 2: Install Java
SonarQube requires Java to run. Install OpenJDK 17 with:
sudo apt install openjdk-17-jdk -y
Verify installation:
java -version
Step 3: Create a SonarQube User
It’s best practice to run SonarQube under a dedicated user account for security:
sudo adduser --system --no-create-home --group --disabled-login sonarqube
Step 4: Download and Install SonarQube
Navigate to the /opt directory and download SonarQube:
cd /opt
sudo wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-9.9.1.69595.zip
sudo unzip sonarqube-9.9.1.69595.zip
sudo mv sonarqube-9.9.1.69595 sonarqube
Set permissions for the SonarQube user:
sudo chown -R sonarqube:sonarqube /opt/sonarqube
Step 5: Configure SonarQube as a Service
Create a systemd service file to manage SonarQube:
sudo nano /etc/systemd/system/sonarqube.service
Add the following:
[Unit]
Description=SonarQube service
After=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=65536
LimitNPROC=4096
[Install]
WantedBy=multi-user.target
Save and exit. Then enable and start SonarQube:
sudo systemctl enable sonarqube
sudo systemctl start sonarqube
Step 6: Access the SonarQube Dashboard
Once running, SonarQube is accessible via your server’s IP address on port 9000. Open a browser and go to:
http://your_server_ip:9000
Log in with the default credentials:
-
Username: admin
-
Password: admin
You’ll be prompted to reset the password and can then start configuring your projects.
