在传输层[NettyTcpChannel {localAddress = / x：40554，remoteAddress = / y：9300}]上捕获到错误异常，关闭了连接

编程问答 2022-08-11

问题描述

我正在使用弹性搜索和spring数据搜索，我已经在EC2实例中配置了弹性搜索，因此最初我将网络主机设置为0.0.0.0，但随后将其绑定到实例的专用IP的网络主机，并且从那我得到这个错误。虽然如果我在http：// pvtIp：9200上进行卷曲，并且可以正常运行，并且同一http：// pvtIp：9200 / nodes仅将返回的传输层作为私有ip返回给我，但仍然无法正常工作。我检查了在托管代码的弹性beantalk实例中是否配置了任何类型的弹性搜索，但都不存在

还要注意，仅当我将代码移至服务器时才会触发此错误，即使在詹金斯从事这项工作的时候也是如此

我做到了：sudo service elasticsearch status无法识别弹性搜索 即使sudo netstat -ntlp也不返回9200和9300开放的端口
