我正在嘗試在我的 Windows 系統中設定 elasticsearch，但是當我嘗試運行它時，它會啟動并在我重定向到http://localhost:9200.

{
  "name" : "DESKTOP-L8UKCFI",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "z8IfZcFaQfSti3P4jhZxbg",
 "version" : {
   "number" : "8.1.0",
   "build_flavor" : "default",
   "build_type" : "zip",

   "minimum_wire_compatibility_version" : "7.17.0",
   "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
 }

但是在控制臺中它顯示的是這樣的

> # ======================== Elasticsearch Configuration =========================

注意：Elasticsearch 為大多數設定提供了合理的默認值。

在開始調整和調整配置之前，請確保您

了解你想要完成什么以及后果。

配置節點的主要方法是通過此檔案。該模板列出

您可能想要為生產集群配置的最重要的設定。

有關配置選項的更多資訊，請參閱檔案：

https://www.elastic.co/guide/en/elasticsearch/reference/index.html

- - - - - - - - - - - - - - - - - 簇 - - - - - - - - --------------------

為您的集群使用描述性名稱：

#cluster.name: my-application

------------------------------------ Node ------------------------------------

Use a descriptive name for the node:

#node.name: node-1

Add custom attributes to the node:

#node.attr.rack: r1

----------------------------------- Paths ------------------------------------

Path to directory where to store the data (separate multiple locations by comma):

#path.data: /path/to/data

Path to log files:

#path.logs: /path/to/logs

----------------------------------- Memory -----------------------------------

Lock the memory on startup:

#bootstrap.memory_lock: true

Make sure that the heap size is set to about half the memory available

on the system and that the owner of the process is allowed to use this

limit.

Elasticsearch performs poorly when the system is swapping the memory.

---------------------------------- Network -----------------------------------

By default Elasticsearch is only accessible on localhost. Set a different

address here to expose this node on the network:

#network.host: 192.168.0.1

By default Elasticsearch listens for HTTP traffic on the first free port it

finds starting at 9200. Set a specific HTTP port here:

#http.port: 9200

For more information, consult the network module documentation.

--------------------------------- Discovery ----------------------------------

Pass an initial list of hosts to perform discovery when this node is started:

The default list of hosts is ["127.0.0.1", "[::1]"]

#discovery.seed_hosts: ["host1", "host2"]

Bootstrap the cluster using an initial set of master-eligible nodes:

#cluster.initial_master_nodes: ["node-1", "node-2"]

For more information, consult the discovery and cluster formation module documentation.

---------------------------------- Various -----------------------------------

Allow wildcard deletion of indices:

#action.destructive_requires_name: false

#----------------------- BEGIN SECURITY AUTO CONFIGURATION -----------------------

The following settings, TLS certificates, and keys have been automatically

generated to configure Elasticsearch security features on 16-03-2022 06:55:18

--------------------------------------------------------------------------------

Enable security features

xpack.security.enabled: false

xpack.security.enrollment.enabled: false

Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents

xpack.security.http.ssl: enabled: false keystore.path: certs/http.p12

Enable encryption and mutual authentication between cluster nodes

xpack.security.transport.ssl: enabled: false verification_mode: certificate keystore.path: certs/transport.p12 truststore.path: certs/transport.p12

Create a new cluster with the current node only

Additional nodes can still join the cluster later

cluster.initial_master_nodes: ["DESKTOP-L8UKCFI"]

Allow HTTP API connections from localhost and local networks

Connections are encrypted and require user authentication

http.host: [local, site]

Allow other nodes to join the cluster from localhost and local networks

Connections are encrypted and mutually authenticated

#transport.host: [local, site]

#----------------------- END SECURITY AUTO CONFIGURATION -------------------------

有人告訴我是什么意思。

uj5u.com熱心網友回復：

從 ES 8 開始，HTTP 客戶端默認開啟 SSL/TLS。

警告訊息說

http client did not trust this server's certificate

...這意味著您需要告訴您的瀏覽器信任服務器證書。默認情況下它是自簽名的，所以這可能就是原因。

或者您可以簡單地在您的配置中禁用 SSL elasticsearch.yml，這也可以。
