es版本:6.3.2

查看許可狀態(tài)

可以看到是basic，需要啟用 trial license

curl -H "Content-Type:application/json" -XPOST  http://<host>:<port>/_xpack/license/start_trial?acknowledge=true

然后在elasticsearch.yml文件中增加如下配置：

http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type
xpack.security.enabled: true

重啟es，然后執(zhí)行.\elasticsearch-setup-passwords.bat interactive設(shè)置密碼。
如果沒加xpack的配置，直接設(shè)置密碼會報錯，如下：

Unexpected response code [403] from calling GET http://*.*.*.*:9200/_xpack/security/_authenticate?pretty
It doesn't look like the X-Pack security feature is available on this Elasticsearch node.
Please check if you have installed a license that allows access to X-Pack Security feature.

ERROR: X-Pack Security is not available.

執(zhí)行.\curl.exe http://<host>:<port>測試連接，報錯，連接失敗。
然后再執(zhí)行.\curl.exe http://<host>:<port> -u elastic:<password>連接成功。
或者也可以直接瀏覽器訪問http://<host>:<port>驗證結(jié)果。
