Nginx service is running successfully but returns apache default page?

Question

i installed nginx on server(ubuntu 16.04) which already had apache2 and, done this following configuration,

->changed apache port 80 to 8888 so nginx would listen to 80
->restarted apache and nginx in sequence.

still getting apache default page when i type http://localhost i also stopped apache2 service and restarted nginx service to ensure only once server run at time but still getting apache default page on localhost request!!! which should be actually nginx default page cuase apache service is not running anymore.

One thing i found suspicious is 'htcacheclean' process is running,is that responsible for the returning Apache page?!

how this is happening is strange for me!! kindly share hint if you ever faced this kind of issue.

ss -tlnp return following for the port 80
State   Recv-Q  Send-Q     Local Address:Port   Peer Address:Port
LISTEN    0        0                     *:80                      **:* *

ss -tlnp | grep nginx command output shows nginx

Answer 1

Its because nginx may have same DocumentRoot as apache and It's index.html is still in /var/www/html. I had the same problem.

Answer 2

Faced the same issue in my linux. Solution is to purge apache2 entirely. for me the command - sudo apt purge apache2

Here is the complete solution to the problem-

1. use gunicorn to start your django site
2. edit nginx configurations to tell it to listen on another port except port 80

3.Boom solved.(Don't forget to restart nginx)

Here is how to- (my django site name is 'mysite'; replace it with yours(folder containing wsgi file.))

1. in your django site folder command:gunicorn mysite.wsgi:application
2. editing nginx - command: sudo nano /etc/nginx/sites-available/mysite_nginx.conf with code:-

server { listen 8001; server_name 192.168.1.36; # Your machine's local IP address

location / {
    proxy_pass http://127.0.0.1:8000;  # Gunicorn's default bind address
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

And then, create a symlink for it- command: sudo ln -s /etc/nginx/sites-available/mysite_nginx.conf /etc/nginx/sites-enabled

3.Restart nginx service- command: sudo service nginx restart or command: sudo /etc/init.d/nginx start

Finally, it will be available to every device connected to your local network use 'http://your_machine_ip:8001' to access it

Pardon me for beginner silly mistakes; I'm new to it.
