sudo systemctl status postgresqlStep 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 postgresit prompts to set password for postgres admin user.
Now switch to postgres user
su - postgrescreate new user by typing below.
createuser sonarnow switch to the postgresql shell
psqlcreate database,set privileges to user and set the password to user sonar.
postgres=# CREATE DATABASE sonarqube OWNER sonar;
CREATE DATABASE
postgres=# GRANT ALL PRIVILEGES ON DATABASE sonarqube to sonar;
GRANT
postgres=# ALTER USER sonar WITH ENCRYPTED PASSWORD 'Strong_PWORD';
ALTER ROLE
now exit from postgres console and also from postgres user.
postgres=# \q

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;
}
}you can nginx syntax errors using below command.
nginx -tthen enable nginx website using link file
ln -s /etc/nginx/sites-available/sonarqube.conf /etc/nginx/sites-enabled/save and close the file and restart nginx service.
sudo systemctl restart nginxStep 10: Access sonarqube
Now open your favorite browser to access SonarQube using the address http://ip_address or Host address. you can login with default username and password as admin.once you are loggedin you can reset password and use.
