连接被拒绝-使用graphaware连接Neo4j/ES docker集装箱

我正在尝试使用graphaware连接Neo4j和ES docker容器，我得到了看起来像docker-to-docker连接问题的结果

org.apache.http.conn.HttpHostConnectException: Connect to 127.0.0.1:9201 [/127.0.0.1] failed: Connection refused (Connection refused)

我可以使用浏览器通过http访问这两个容器数据。在这个阶段，我不知道问题的实际位置，因为我对这些技术非常陌生

我正在使用的版本：

• neo4j:3.5.3
• ElasticSearch 6.6.1
• graphaware-neo4j-to-elasticsearch-3.5.2.53.11.jar
• graphaware-server-community-all-3.5.2.jar
• graphaware-uuid-3.5.2.53.17.jar
• 码头工人：18.09.3

这是我的yml文件

最可能的问题是，您的neo4j正试图连接到与neo4j运行在同一台机器上的elasticsearch

#URI of Elasticsearch; elastic works as well
com.graphaware.module.ES.uri=127.0.0.1

#Port of Elasticsearch
com.graphaware.module.ES.port=9201

Elasticsearch未在同一台计算机上运行，您应该避免在配置文件上使用127.0.0.1，尝试将localhost地址交换为本地dns地址以获得ES

#URI of Elasticsearch; elastic works as well
com.graphaware.module.ES.uri=elastic

#Port of Elasticsearch
com.graphaware.module.ES.port=9201

我还建议（通过了解问题的用例），neo4j首先取决于弹性运行，因此如果需要，可以在启动时进行复制。我尝试了这两个建议，但仍然存在相同的问题。org.apache.http.conn.HttpHostConnectException是相同的还是更改为“org.apache.http.conn.HttpHostConnectException:Connect to elastic:9201…”是的，现在是“org.apache.http.conn.HttpHostConnectException:Connect to elastic:9201[elastic/172.24.0.2]失败：连接被拒绝（连接被拒绝）”尝试将elasticsearch.yml中的network.host配置更改为0.0.0.0
