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。
