• This guide will help you understand the process of Installing SonarQube on Ubuntu 24 for a secure and efficient setup.

Install Java (Java 21)

SonarQube 25.12 requires Java 21 as the preferred JDK for the server.

Install Java 21

sudo apt update
sudo apt install openjdk‑21‑jdk ‑y

Verify:

java ‑version

Install PostgreSQL

sudo apt install postgresql postgresql‑contrib ‑y

Create database and user for Sonar:

sudo -i -u postgres
psql

Inside psql:

CREATE DATABASE sonarqube;
CREATE USER sonar WITH ENCRYPTED PASSWORD 'YourStrongPass!';
GRANT ALL PRIVILEGES ON DATABASE sonarqube TO sonar;
\q
exit

Create SonarQube User

sudo useradd -m -d /opt/sonarqube -s /bin/bash sonar

 Download and Extract SonarQube 25.12

Download the specific version:

cd /opt
sudo wget https://dl.sonarsource.com/communitybuilds/sonarqube/25.12.0.117093/sonarqube‑25.12.0.117093.zip
sudo unzip sonarqube‑25.12.0.117093.zip
sudo mv sonarqube‑25.12.0.117093 sonarqube
sudo chown -R sonar:sonar sonarqube

 Configure SonarQube

Open the main config:

sudo nano /opt/sonarqube/conf/sonar.properties

Update database settings:

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

Specify web host & port:

sonar.web.host=0.0.0.0
sonar.web.port=9000

Save and exit.

Set Up systemd Service

Create unit file:

sudo nano /etc/systemd/system/sonarqube.service

Add the following:

[Unit]
Description=SonarQube 25.12 service
After=network.target postgresql.service

[Service]
Type=forking
ExecStart=/opt/sonarqube/bin/linux‑x86‑64/sonar.sh start
ExecStop=/opt/sonarqube/bin/linux‑x86‑64/sonar.sh stop
User=sonar
Group=sonar
Restart=always
LimitNOFILE=65536
LimitNPROC=4096

[Install]
WantedBy=multi‑user.target

Reload and enable:

sudo systemctl daemon‑reload
sudo systemctl enable sonarqube
sudo systemctl start sonarqube

Check status:

sudo systemctl status sonarqube

 Access SonarQube

Open browser:

http://<YOUR_SERVER_IP>:9000

Installing SonarQube 25.12 involves Java 21, PostgreSQL, and a dedicated system user for security.

Running SonarQube as a systemd service ensures automatic startup and management.

Using a reverse proxy (Nginx) and optional HTTPS improves accessibility and security.

SonarQube enables continuous code quality monitoring, helping teams detect bugs and vulnerabilities early.
