I want to configure a test cluster  
Here is my node 2 configuration information：

cluster.name: esapp  
node.name: node-2  
node.master: false  
node.data: true  
network.host: 0.0.0.0  
discovery.zen.ping.unicast.hosts: ["192.168.1.171:9200", "192.168.1.167:9200"]  
discovery.zen.minimum\_master\_nodes: 2

Error information is thrown when node 2 starts：

Communication within the cluster uses port 9300, not 9200.

With this setting you should have 2 or 3 master eligible nodes. Given that you have set `node.master` to `false` for this node and only listed 2 nodes, this may be a problem as well.

Please don't post images of text as they are hardly readable and not searchable.

Instead paste the text and format it with `</>` icon. Check the preview window.
