sonnar qube installation

1

Launch EC2 Instance

• Log in to AWS Management Console.

• Launch an EC2 instance:

  • Choose Amazon Linux 2 or Ubuntu Server.

  • Select instance type (e.g., t2.medium or better recommended for SonarQube).

  • Configure security groups to allow inbound ports:

    • SSH (port 22) for access

    • HTTP (port 9000) for SonarQube UI

2

Connect to EC2 Instance

Use SSH to connect to your instance from your terminal:

ssh -i /path/to/your-key.pem ec2-user@<EC2-PUBLIC-IP>

3

Update System Packages

Amazon Linux 2

sudo yum update -y

Ubuntu

4

Install Java (SonarQube requires Java 11 or higher)

Amazon Linux 2

sudo amazon-linux-extras install java-openjdk11 -y

Ubuntu

Verify Java installation:

java -version

5

Create SonarQube User

Create a dedicated user to run SonarQube:

sudo useradd sonar
sudo passwd sonar

6

Download SonarQube

Navigate to /opt (or choose a directory of your preference) and download the SonarQube Community Edition:

cd /opt
sudo wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-10.0.0.60804.zip

Note: Replace the link with the current version from the SonarQube download page if needed.

7

Unzip SonarQube

Amazon Linux 2

sudo yum install unzip -y

Ubuntu

Then unzip and set ownership:

sudo unzip sonarqube-10.0.0.60804.zip
sudo mv sonarqube-10.0.0.60804 sonarqube
sudo chown -R sonar:sonar sonarqube

8

Configure SonarQube

Edit the SonarQube configuration file:

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

• Set database connection if you plan to use an external database (by default it uses embedded H2 for testing).

• (Optional) Edit sonar.web.host=0.0.0.0 to make it accessible on all interfaces.

Save and exit.

9

(Optional) Install and Configure PostgreSQL (for production)

SonarQube recommends PostgreSQL or MySQL for production. The embedded H2 DB is suitable for testing only.

If you want PostgreSQL installed (example for Amazon Linux 2):

sudo amazon-linux-extras enable postgresql13
sudo yum install postgresql postgresql-server postgresql-devel postgresql-contrib postgresql-docs -y
sudo service postgresql initdb
sudo service postgresql start
sudo -i -u postgres psql

Then create the database and user for SonarQube inside the psql prompt.

10

Start SonarQube

Switch to the sonar user and start SonarQube:

sudo su - sonar
cd /opt/sonarqube/bin/linux-x86-64
./sonar.sh start

11

Access SonarQube Web Interface

• Open your browser and navigate to:

  http://<EC2-PUBLIC-IP>:9000

• Login with default credentials:

  Username: admin
  Password: admin

12

Optional — Configure SonarQube as a systemd Service

Create the systemd unit file /etc/systemd/system/sonarqube.service with the following content:

[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=sonar
Restart=always

[Install]
WantedBy=multi-user.target

Reload systemd and enable the service:

sudo systemctl daemon-reload
sudo systemctl enable sonarqube
sudo systemctl start sonarqube

If you want this adjusted for a different OS or to cover production settings with an external database, tell me which OS and database you'd like and I can adapt the steps.
