Step 3: Install postgresql

we will install postgresql 12 database before installing sonarqube and run the following command to install postgresql db.

sudo systemctl start  postgresql
sudo systemctl enable postgresql
sudo systemctl status postgresql

Step 4: create database

we will create database, user and password and set privileges. so first we will set password for the Postgresql user( system user) with the command.

sudo passwd postgres

it prompts to set password for postgres admin user.

Now switch to postgres user

su - postgres

create new user by typing below.

createuser sonar

now switch to the postgresql shell


create database,set privileges to user and set the password to user sonar.

postgres=# CREATE DATABASE sonarqube OWNER sonar;
postgres=# GRANT ALL PRIVILEGES ON DATABASE sonarqube to sonar;

now exit from postgres console and also from postgres user.

postgres=# \q
postgres@ubuntu20:~$ exit

Add below lines to above file

Description=SonarQube service
After=syslog.target network.target
ExecStart=/opt/sonarqube/bin/linux-x86-64/sonar.sh start

ln -s /etc/nginx/sites-available/sonarqube.conf /etc/nginx/sites-enabled/

save and close the file and restart nginx service.

sudo systemctl restart nginx
