title: Brokers are not available
body: <p>To /etc/kafka/server.properties the broker is configured using:</p>
  <pre><code>############################# Server Basics #############################
  # The id of the broker. This must be set to a unique integer for each broker.
  broker.id=0
  ############################# Socket Server Settings #############################
  # The address the socket server listens on. It will get the value returned from
  # java.net.InetAddress.getCanonicalHostName() if not configured.
  #   FORMAT:
  #     listeners = listener_name://host_name:port
  #   EXAMPLE:
  #     listeners = PLAINTEXT://your.host.name:9092
  listeners=PLAINTEXT://&lt;MY_HOST_NAME&gt;:9092,SASL_SSL://&lt;MY_HOST_NAME&gt;:9093
  </code></pre>
  <p>To check the brokers I run:</p>
  <pre><code>/opt/confluent-kafka/v5.5.0/bin/zookeeper-shell localhost:2181 ls /brokers/ids
  </code></pre>
  <p>Which returns:</p>
  <pre><code>Connecting to localhost:2181
  
  WATCHER::
  
  WatchedEvent state:SyncConnected type:None path:null
  []
  </code></pre>
  <p>So, it seems that the brokers are not running. As kafka server.properties(above) contains:</p>
  <pre><code>listeners=PLAINTEXT://&lt;MY_HOST_NAME&gt;:9092,SASL_SSL://&lt;MY_HOST_NAME&gt;:9093
  </code></pre>
  <p>shouldn't the broker be available ?</p>
  <p>My understanding is <code>listeners=PLAINTEXT://&lt;MY_HOST_NAME&gt;:9092,SASL_SSL://&lt;MY_HOST_NAME&gt;:9093</code> is the config that allows the brokers to be accessible ?</p>
