How to start nginx via different port(other than 80)

Question

Hi I am a newbie on nginx, I tried to set it up on my server(running Ubuntu 4), which already has apache running. So after I `apt-get install` it, I tried to start nginx. Then I get the message like this: ``` Starting nginx: the configuration file /etc/nginx/nginx.conf syntax is ok configuration file /etc/nginx/nginx.conf test is successful [emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use) [emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use) [emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use) [emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use) [emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use) ``` That makes sense as Apache is using port 80. Then I tried to modify `nginx.conf`, I reference some articles, so I changed it like so: ``` server { listen 8080; location / { proxy_pass http://xx.xx.xx.xx:9500; proxy_set_header Host $host:8080; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $prox…

Accepted Answer

You have to go to the `/etc/nginx/sites-enabled/` and if this is the default configuration, then there should be a file by name: `default`.

Edit that file by defining your desired port; in the snippet below, we are serving the Nginx instance on port 81.

```
server {
    listen 81;
}
```

To start the server, run the command line below;

```
sudo service nginx start
```

You may now access your application on port 81 (for localhost, http://localhost:81).
