title: NGINX Unknown Directive Stream
body: <p>I'm trying to setup a UDP Load Balancer using NGINX (1.12.1).</p>
  
  <p>However I'm getting an error...</p>
  
  <blockquote>
    <p>[ec2-user@ip-172-31-0-184 nginx]$ sudo service nginx start Starting
    nginx: nginx: [emerg] unknown directive "stream" in
    /etc/nginx/conf.d/load-balancer.conf:1</p>
  </blockquote>
  
  <p>Here is the config I'm trying to use:</p>
  
  <pre><code>stream {
          upstream backend1 {
                  server 10.0.1.50:450;
          }
  
  upstream backend2 {
                  server 10.0.1.50:500;
          }
  
  # This server accepts all traffic to port 80 and passes it to the upstream.
          # Notice that the upstream name and the proxy_pass need to match.
  
          server {
                  listen 500 udp;
                  proxy_pass backend2;
          }
  
  server {
                  listen 4500 udp;
                  proxy_pass backend1;
          }
  
  }
  </code></pre>
  
  <p>And here is the output of nginx -V, to verify that stream is installed. </p>
