sudo mv sonarqube /opt/

Add sonar group and user:

sudo groupadd sonar
sudo useradd -d /opt/sonarqube -g sonar sonar
sudo chown ddsonar:ddsonar /opt/sonarqube -R
4) Make configuration changes:
sudo nano /opt/sonarqube/conf/sonar.properties
sonar.jdbc.username=sonar
sonar.jdbc.password=mwd#2%#!!#%rgs

sonar.jdbc.url=jdbc:postgresql://localhost:5432/sonarqube
sudo nano /opt/sonarqube/bin/linux-x86-64/sonar.sh
RUN_AS_USER=sonar
5) Setup service:
sudo nano /etc/systemd/system/sonar.service
[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
Group=sonar
Restart=always
LimitNOFILE=65536
LimitNPROC=4096
[Install]
WantedBy=multi-user.target
Restart sonar service:
sudo systemctl enable sonar
sudo systemctl start sonar
sudo systemctl status sonar

6) Modify kernal system limits:
sudo nano /etc/sysctl.conf
Add below lines.
vm.max_map_count=262144
fs.file-max=65536
ulimit -n 65536
ulimit -u 4096
Reboot system:
reboot

7) Access Sonarqube with web interface:
http://server-ip:9000

Confiugure reverse proxy if wanted to open sonarqube with domain name:
Now we want a domain name to take over the IP of the server so that 
instead of hitting the IP we can use the domain name that is TLS 
enabled. 
Let's see how to do so.
Install Nginx:
apt-get install nginx
Add DNS Record:
A record for the server IP in domain provider.
Create Nginx configuration file.
sudo nano /etc/nginx/sites-enabled/sonarqube
server {
listen 80;
server_name sonarqube.blogspot.com;
location / {
proxy_pass http://127.0.0.1:9000;
}
}
verify nginx configuration:

sudo nginx -t
Restart service:
sudo systemctl enable nginx
sudo systemctl restart nginx
sudo systemctl status nginx

Now we can open sonarqube with domain name.

And there you go.
