ERROR: Elasticsearch did not exit normally - check the logs at L:\elasticsearch-8.7.1\logs\elasticsearch.log

ERROR: Elasticsearch exited unexpectedly

处理：

删除环境变量中的CLASSPATH：

另外，elasticsearch8.7.1自带了openjdk 20：

可配置elasticsearch.bat ：

set JAVA_HOME="L:\elasticsearch-8.7.1\jdk\"

重新运行elasticsearch.bat ：

高版本ES 需要https方式访问，如果你需要使用http，修改如下文件：

/config/elasticsearch.yml，将enabled:true 修改为enabled:false

访问：

下一步修改ES密码：

elasticsearch-reset-password.bat -u elastic

默认会生成一个高强度密码：

需自定义elastic密码：
