How to Install SonarQube 25 on ubuntu 22/24

Install SonarQube 25.x (Community Edition) on Ubuntu 22.04 / 24.04

This is a complete fresh installation guide for SonarQube 25.x, using Java 17 and PostgreSQL. All commands include copy buttons for easy use.

Step 1 — Update System

sudo apt update && sudo apt upgrade -y
sudo apt install -y wget unzip curl git apt-transport-https

Step 2 — Install Java 17

sudo apt install -y openjdk-17-jdk
java -version

Step 3 — Install PostgreSQL

sudo apt install -y postgresql postgresql-contrib
sudo systemctl enable --now postgresql

Step 4 — Create SonarQube Database & User

sudo -u postgres psql <<EOF
CREATE ROLE sonaruser WITH LOGIN ENCRYPTED PASSWORD 'StrongPassword123!';
CREATE DATABASE sonarqube OWNER sonaruser ENCODING 'UTF8' LC_COLLATE='C.UTF-8' LC_CTYPE='C.UTF-8';
GRANT ALL PRIVILEGES ON DATABASE sonarqube TO sonaruser;
EOF

Verify database is empty:

sudo -u postgres psql -d sonarqube -c "\dt"

Step 5 — Configure Kernel Limits (Elasticsearch)

echo "vm.max_map_count=524288" | sudo tee -a /etc/sysctl.conf
echo "fs.file-max=65536" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

Set user limits:

sudo tee -a /etc/security/limits.conf <<EOF
sonar   -   nofile   65536
sonar   -   nproc    4096
EOF

Step 6 — Create Dedicated SonarQube User

sudo groupadd sonar
sudo useradd -c "SonarQube User" -d /opt/sonarqube -g sonar -s /bin/bash sonar

Step 7 — Download SonarQube 25.x

Using your specific build: sonarqube-25.11.0.114957.zip

cd /opt
sudo wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-25.11.0.114957.zip
sudo unzip sonarqube-25.11.0.114957.zip
sudo mv sonarqube-25.11.0.114957 sonarqube
sudo chown -R sonar:sonar /opt/sonarqube

Step 8 — Configure SonarQube (sonar.properties)

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

Set the following inside the file:

sonar.jdbc.username=sonaruser
sonar.jdbc.password=StrongPassword123!
sonar.jdbc.url=jdbc:postgresql://localhost:5432/sonarqube
sonar.web.host=0.0.0.0

Step 9 — Create Systemd Service

sudo tee /etc/systemd/system/sonarqube.service > /dev/null <<EOF
[Unit]
Description=SonarQube 25.x Service
After=network.target postgresql.service

[Service]
Type=forking
User=sonar
Group=sonar
ExecStart=/opt/sonarqube/bin/linux-x86-64/sonar.sh start
ExecStop=/opt/sonarqube/bin/linux-x86-64/sonar.sh stop
Restart=always
LimitNOFILE=65536
LimitNPROC=4096
Environment="JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64"

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload

Step 10 — Start SonarQube

sudo systemctl start sonarqube
sudo systemctl enable sonarqube

Check service status:

systemctl status sonarqube

Check logs (new location for 25.x):

tail -f /opt/sonarqube/var/logs/web.log

Step 11 — Open Firewall

sudo ufw allow 9000/tcp
sudo ufw status

Step 12 — Access the UI

http://YOUR_SERVER_PUBLIC_IP:9000
