1. SkyWalking启动报错 Caused by: io.netty.channel.AbstractChannel$AnnotatedConnectException: finishConnect(..) failed: Connection refused: elasticsearch/localhost:9200
skywalking源码地址:https://github.com/apache/skywalking
经调查,发现是skywalking和elasticsearch的版本不匹配,需要修改skywalking的版本,或者修改elasticsearch的版本。
elasticsearch只是skywalking的一种存储方式,所以,skywalking需要适配es。所以不是每个版本的skywalking和es都能正常工作。
报错的docker_compose.yml为:
