Hello,

I have observed that, Nginx configured on port 80 as per /etc/nginx/sites-enabled/default file but it is listening on port 8080 and 80. Please see the details for the same.

server {
listen 80;
server_name example.com;

location / {
proxy_pass http://localhost:8009;
send_timeout 6000;
proxy_read_timeout 120;
proxy_connect_timeout 120;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
}
}

Port 8080 is listening on Public IP address.
# sudo netstat -anop | grep :8080
tcp 0 0 Public_IP:8080 0.0.0.0:* LISTEN 18674/nginx off (0.00/0/0)

Port 80 is listening on 0.0.0.0
# sudo netstat -anop | grep :80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 18674/nginx off (0.00/0/0)

When I am trying to start the nginx service without init.d script getting below message.

#sudo /usr/sbin/nginx
[sudo] password for xyz:
