SonarQube installation

• In /etc/sysctl.conf, add a line vm.max_map_count=262144 and reboot the server. To verify after rebooting, run sysctl vm.max_map_count. See https://www.elastic.co/guide/en/elasticsearch/reference/current/vm-max-map-count.html for details.

• $ sudo adduser sonar

• $ sudo unzip <sonarqube_zip_file> -d /opt

• rename exploded folder to /opt/sonarqube and $ sudo chown -R sonar: /opt/sonarqube

• Modify /opt/sonarqube/conf/sonar.properties with correct DB values

• Create the /etc/systemd/system/sonarqube.service, ensuring it runs as sonar user. We can initially put RestartSec=360 under [Service] and change this once everything is ok.

• $ sudo systemctl start sonarqube and monitor logs in /opt/sonarqube/logs/ folder, especially sonar.log and web.log files for errors.

• The webpage can be access with http://hostname:9000 with default username password admin / admin

• $ sudo systemctl enable sonarqube if everything is ok.
