It scans your source code looking for potential bugs, vulnerabilities, and maintainability issues, and then presents the results in a report which will allow you to identify potential issues in your application. ## Step 1 - Perform a system update Before installing any packages on the Ubuntu server instance, it is recommended to update the system. Log in using the sudo user and run the following commands to update the system. ```bash sudo apt-get update sudo apt-get -y upgrade ``` ## Step 2- Install and configure PostgreSQL Install the PostgreSQL repository. ```bash sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list' wget -q https://www.postgresql.org/media/keys/ACCC4CF8.asc -O - | sudo apt-key add - ``` Install the PostgreSQL database server by running: ```bash sudo apt-get -y install postgresql postgresql-contrib ``` Start PostgreSQL server and enable it to start automatically at boot time by running: ```bash sudo systemctl start postgresql sudo systemctl enable postgresql ``` Change the password for the default PostgreSQL user. ```bash sudo passwd postgres ``` Switch to the postgres user. ```bash su - postgres ``` Create a new user by typing: ```bash createuser sonar ``` Switch to the PostgreSQL shell. ```bash psql ``` Set a password for the newly created user for SonarQube database. ```sql ALTER USER sonar WITH ENCRYPTED password 'P@ssword'; ``` Create a new database for PostgreSQL database by running: ```sql CREATE DATABASE sonar OWNER sonar; ``` Exit from the psql shell: ```sql \q ``` Switch back to the sudo user by running the exit command. ```bash exit ``` ## Step 3: Download and configure SonarQube Download the SonarQube installer files archive. ```bash wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-7.3.zip ``` You can always look for the link to the latest version of the application on the [SonarQube download page](https://www.sonarqube.org/downloads/?ref=developerinsider.co). Install unzip by running: ```bash apt-get -y install unzip ``` Unzip the archive using the following command. ```bash sudo unzip sonarqube-7.3.zip -d /opt ``` Rename the directory: ```bash sudo mv /opt/sonarqube-7.3 /opt/sonarqube ``` Assign permissions to administrator user for directory /opt/sonarqube ```bash sudo chown -R administrator:administrator /opt/sonarqube/ ``` Open the SonarQube configuration file using your favorite text editor. ```bash sudo nano /opt/sonarqube/conf/sonar.properties ``` Find the following lines. ```txt #sonar.jdbc.username= #sonar.jdbc.password= ``` Uncomment and provide the PostgreSQL username and password of the database that we have created earlier. It should look like: ```txt sonar.jdbc.username=sonar sonar.jdbc.password=P@ssword ``` Next, find: ```txt #sonar.jdbc.url=jdbc:postgresql://localhost/sonar ``` Uncomment the line, save the file and exit from the editor. Finally, tell SonarQube to run in server mode : ```txt sonar.web.javaAdditionalOpts=-server ``` ## Step 4: Configure Systemd service SonarQube can be started directly using the startup script provided in the installer package. As a matter of convenience, you should setup a Systemd unit file for SonarQube. ```bash sudo nano /etc/systemd/system/sonar.service ``` Populate the file with: ```txt [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=root Group=root Restart=always [Install] WantedBy=multi-user.target ``` Start the application by running: ```bash sudo systemctl start sonar ``` Enable the SonarQube service to automatically start at boot time. ```bash sudo systemctl enable sonar ``` To check if the service is running, run: ```bash sudo systemctl status sonar ``` ## Step 5 - Setup Nginx Now that we've got the SonarQube server running, it's time to configure Nginx. Start by creating a new Nginx configuration file for the site: ```bash sudo nano /etc/nginx/sites-enabled/sonarqube ``` Add this configuration so that Nginx will be able to route incoming traffic to SonarQube: ```txt server{ listen 9000; server_name sonarqube.developerinsider.co; access_log /var/log/nginx/sonar.access.log; error_log /var/log/nginx/sonar.error.log; proxy_buffers 16 64k; proxy_buffer_size 128k; location / { proxy_pass http://127.0.0.1:9000; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto http; } } ``` Save and close the file. Next, make sure your configuration file has no syntax errors: ```bash sudo nginx -t ``` If you see errors, fix them and run sudo nginx -t again. Once there are no errors, restart Nginx: ```bash sudo service nginx restart ``` ## Step 6 — Setting Up SonarQube To set up your installation navigate to your server's domain name or public IP address: http://server\_domain\_name\_or\_IP. If you've setup in you local system then visit [http://127.0.0.1:9000/](http://127.0.0.1:9000/?ref=developerinsider.co) For more details you can read Sonarqube Official docs [here](https://docs.sonarqube.org/latest/?ref=developerinsider.co).
