Elasticsearch.yml configuration file for

elasticsearch.yml is as follows:

cluster.name: es-cluster
node.name: es-node
path.data: /home/bigdata/cluster/elasticsearch/data
path.logs: /home/bigdata/cluster/elasticsearch/logs
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
network.host: 192.168.159.7
discovery.zen.ping.unicast.hosts: ["linux"]

There should be a space between the

colon and the attribute value (note when configuring). The host name is Linux. The reason for this problem is that the value of the configuration item of net.host cannot be written as the host name Linux, that is, network. Use IP addresses, not hostnames, when possible during configuration.
as shown in the figure below:
