title: ElasticSearch installation error - curl: (7) Failed connect to localhost:9200; Connection refused
body: <p>I'm trying to configure ElasticSearch with <a href="https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-elasticsearch-on-centos-7" rel="noreferrer">this</a> tutorial </p>
  
  <p>I did everything except step 4 of the tutorial.</p>
  
  <hr>
  
  <p>In step 5, when I run this command:</p>
  
  <pre><code>curl -X GET 'http://localhost:9200'
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>curl: (7) Failed connect to localhost:9200; Connection refused
  </code></pre>

  <p>I have tried two different things to fix the error: </p>
  
  <ol>
  <li><p>network.bind_host: 0.0.0.0</p></li>
  <li><p>network :
  host : 192.168.2.229</p></li>
  </ol>
  
  <p>But neither solved the problem.  </p>
  
  <p>What should I do to test Elasticsearch and solve this error?</p>
  
  <p>Thanks.</p>
