How to run Nginx on a different port other than 80

I cannot run Nginx because port 80 is already listening on a docker-proxy service.

tcp6     0     0 :::80          :::*           LISTEN      13110/docker-proxy

I would like to run Nginx on port 8800 instead of the default port 80.

As such, I've edited the default file as below;

sudo nano /etc/nginx/sites-available/default

listen 8800 default_server;
listen [::]:8800 default_server;
listen localhost;

However, I still cannot get it working as expected even after restart.

What am I doing wrong and how can I resolve it?

Below is the error I get;

It looks like the problem is in the line

        listen localhost;

The "listen" directive can take a port number, a host, or both. I believe in your case this line defaults the port to 80, which would cause the problems you are experiencing.

Also, beware if "default" is not the only file in hosts_available. Each of these (each server block) will default to using port 80 unless overridden there. Just editing "default" would not be enough in that case.

You have to go to the /etc/nginx/sites-enabled/default

Edit that file and put (If you are willing to put "8800" as your port for nginx)

server { listen 8800; }

The start the server

sudo service nginx start

or

sudo service nginx restart if previously running.

Then access localhost:8800

Add a rule to iptables

 vi /etc/sysconfig/iptables 
 -A INPUT -m state --state NEW -m tcp -p tcp --dport 8800 -j ACCEPT

Restart IPtables

sudo service iptables restart;

I found this answer on Server Fault helpful: https://serverfault.com/questions/655067/is-it-possible-to-make-nginx-listen-to-different-ports

You can add ports to the one server block to keep things simple:

server {
    listen 80;
    listen 8000;
    server_name example.org;
    root /var/www/;
}
