This article mainly shows you the "ES search installation will encounter what problems", the content is easy to understand, clear, hope to help you solve the doubt, the following let the editor lead you to study and learn "ES search installation will encounter what problems" this article.

Access port 9200 after ES installation to display normal version data, but an error is reported when using search

{"error": {"root_cause": [{"type": "cluster_block_exception", "reason": "blocked by: [SERVICE_UNAVAILABLE/1/state not recovered / initialized];"}], "type": "cluster_block_exception", "reason": "blocked by: [SERVICE_UNAVAILABLE/1/state not recovered / initialized];"}, "status": 503}

Because I am not familiar with it, I have been using this mistake to investigate. I have checked a lot of information, but it is of no avail.

Later, I saw that you can check the status with http://localhost:9200/_cluster/health?pretty=true and return an error:

{"error": {"root_cause": [{"type": "master_not_discovered_exception", "reason": null}], "type": "master_not_discovered_exception", "reason": null}, "status": 503}

Check along this path and find that the reason is that all the node names set in the cluster are previously modified, of course, you can also use the default, which is currently stand-alone, and you can put it into one node. Note here that if it is currently a single node, be sure to change the value to the name of the node, otherwise, although the startup is successful, there will be a "master_not_discovered_exception" error when adding data to the elasticsearch service through the curl command.

Cluster.initial_master_nodes: ["node-1"] xpack.security.transport.ssl.enabled: truexpack.security.enabled: true

After setting up the node, status green, problem solved
