SonarQube is a free, open-source, self-managed code review tool that systematically helps you deliver clean code. It is a very useful quality analysis tool to scan source code for potential bugs and vulnerabilities and generates a report. SonarQube supports up to 30 programming languages and provides reports such as duplicate code, coding standards, code complexity, and security recommendation.

This post will show you how to install the SonarQube code analysis tool on Fedora.

Step 1 – Install Java OpenJDK

SonarQube is written in Java, so Java JDK must be installed on your server. If not installed, you can install it with the following command.

dnf install java-17-openjdk -y

Once Java is installed, you can verify the Java installation using the following command.

java --version


openjdk 17.0.3 2022-04-19
OpenJDK Runtime Environment 21.9 (build 17.0.3+7)
OpenJDK 64-Bit Server VM 21.9 (build 17.0.3+7, mixed mode, sharing)

Step 2 – Install and Configure PostgreSQL Database

First, disable the default PostgreSQL repo and enable the PostgreSQL 14 repo.

dnf module reset postgresql -y
dnf module enable postgresql:14

Next, install the PostgreSQL server with the following command.

dnf install postgresql-server postgresql

Next, initialize the PostgreSQL database using the following command.

postgresql-setup --initdb

Next, start the PostgreSQL service and enable it to start at system reboot.

systemctl enable --now postgresql

Next, log in to the PostgreSQL shell with the following command.

su - postgres

Next, create a database and user for SonarQube.

create user sonar;
create database sonar owner sonar;
grant all privileges on database sonar to sonar;

Next, set a password for the sonar user, then exit from the PostgreSQL shell.

ALTER USER sonar WITH ENCRYPTED password 'secure_password';

Next, edit the PostgreSQL configuration file.

nano /var/lib/pgsql/data/pg_hba.conf

Find the following lines:

host    all             all               ident
host    all             all             ::1/128                 ident

And, replace them with the following lines:

host    all             all               md5
host    all             all             ::1/128                 md5

Save and close the file, then reload the PostgreSQL service to implement the changes.

systemctl reload postgresql

Step 3 – Install and Configure SonarQube

First, create a dedicated user to run SonarQube.

useradd -M -d /opt/sonarqube/ -r -s /bin/bash sonar

Next, download the latest version of SonarQube.


Next, unzip the SonarQube and move the unzipped directory to /opt

mv sonarqube-  /opt/sonarqube

Next, change the ownership of the SonarQube directory.

chown -R sonar:sonar /opt/sonarqube

Next, edit the SonarQube configuration file.

nano /opt/sonarqube/conf/

Define your database settings, host, port, Java options, and data directory.


##How you will access SonarQube Web UI

##Java options
sonar.web.javaOpts=-Xmx512m -Xms128m -XX:+HeapDumpOnOutOfMemoryError -Xms512m -XX:MaxDirectMemorySize=256m -XX:+HeapDumpOnOutOfMemoryError

##Also uncomment the following Elasticsearch storage paths

Save and close the file, then create a new wrapper.conf file and define your Java path.

nano /opt/sonarqube/conf/wrapper.conf

Add the following line.

Save and close the file when you are done.

Step 4 – Create a Systemd Service File for SonarQube

Next, create a systemd file to manage the SonarQube service.

nano /etc/systemd/system/sonarqube.service

Add the following lines.

Description=SonarQube service

ExecStart=/opt/sonarqube/bin/linux-x86-64/ start
ExecStop=/opt/sonarqube/bin/linux-x86-64/ stop


Save and close the file, then reload the systemd daemon to apply the changes.

systemctl daemon-reload

Next, start and enable the SonarQube service.

systemctl start sonarqube
systemctl enable sonarqube

You can verify the SonarQube status using the following command.

systemctl status sonarqube

Step 5 – Access SonarQube Web Dashboard

Now, open your web browser and access the SonarQube web UI using the URL http://server-ip:9000. You should see the SonarQube login screen.

Sonarqube Login

Provide the default username and password as admin/admin then click on the Log in button. You should see the password change screen.

SOnarqube password change

Set your new admin password then click on the Update button. You should see the SonarQube dashboard on the following screen.
