[KenChung]

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：

I'm a beginner.

@KenChung

discovery.zen.ping.unicast.hosts: ["192.168.1.171:9200", "192.168.1.167:9200"]

Communication within the cluster uses port 9300, not 9200.

@KenChung

discovery.zen.minimum_master_nodes: 2

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.
