es启动报错BindException: Can't assign requested address

Posted 2023-05-16

参考技术A mac上启动es报如下错误： BindException[Can't assign requested address]; Likely root cause: java.net.BindException: Can't assign requested address

从错误日志看 ...BindException，Can't assign requested address.. ， 是启动时候无法使用端口或者IP，查看端口占用情况： lsof -i:9200 端口未被使用，

打开es配置文件 elasticsearch.yml , 目录 /usr/local/etc/elasticsearch

使用的 ip：192.168.0.1 改为 127.0.0.1 重启服务问题解决。

ES启动闪退报错

• 直接双击elasticsearch.bat会闪退看不到报错信息,可以去dos命令行启动查看报错信息

• 看提示是让去yml文件中配置xpack.ml.enabled: false

you can use the other X-Pack features (unsupported) by setting xpack.ml.enabled: false in elasticsearch.yml]

• 成功解决启动成功,访问本机9200端口成功OK
