"warning: usage of JAVA_HOME is deprecated, use ES_JAVA_HOME"
Future versions of Elasticsearch will require Java 11; your Java version from [C:\Program Files\Java\jdk1.8.0_241\jre] does not meet this requirement. Consider switching to a distribution of Elasticsearch with a bundled JDK. If you are already using a distribution with a bundled JDK, ensure the JAVA_HOME environment variable is not set.
Warning: with JDK 8 on Windows, Elasticsearch may be unable to derive correct
  ergonomic settings due to a JDK issue (JDK-8074459). Please use a newer
  version of Java.
Warning: MaxDirectMemorySize may have been miscalculated due to JDK-8074459.
  Please use a newer version of Java or set MaxDirectMemorySize explicitly.

不报错了。

启动ES

 .\elasticsearch.bat

提示[2023-08-17T14:30:12,880][INFO ][o.e.x.s.s.SecurityStatusChangeListener] [DESKTOP-QT6GKBM] Active license is now [BASIC]; Security is disabled

活动许可证现在为[BASIC]；安全性已禁用

就卡在这里了，哎。

检查是否成功启动

在浏览器中输入：http://localhost:9200/?pretty

 

出现这样的结果。Elasticsearch 现在已设置并正在运行，但是没有密码保护。 Elastic Stack 免费提供基于角色的访问控制（RBAC）。

先用用试试，在修改他的安全性吧。
