title: Change Nginx port from 80
body: <p>Im trying to change the port that <code>Nginx</code> uses from port <code>80</code> to <code>5555</code> </p>
  
  <p>I've gone into <code>nano /etc/nginx/sites-enabled/default</code> 
  and edited:</p>
  
  <pre><code>server {
           listen 5555;
  }
  </code></pre>
  
  <p>But when I try to restart I get:</p>
  
  <pre><code>$ service nginx restart
  Restarting nginx: nginx.
  nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
  nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
  nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
  nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
  nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
  nginx: [emerg] still could not bind()
  </code></pre>
  
  <p>Am I missing something?</p>
