[英]connection refused - connecting Neo4j/ES docker containers with graphaware
我正在嘗試使用graphaware連接Neo4j和ES docker容器,我得到了看起來像docker到docker的連接問題。
org.apache.http.conn.HttpHostConnectException: Connect to 127.0.0.1:9201 [/127.0.0.1] failed: Connection refused (Connection refused)
我可以使用瀏覽器通過http訪問這兩個容器數據。 由於我對這些技術還很陌生,因此在此階段我不知道問題的實際位置。
我使用的版本:
這是我的yml文件。

和elasticsearch.yml

問題很可能是您的neo4j試圖連接到與neo4j在同一台計算機上運行的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不在同一台機器上運行,因此應避免在配置文件上使用127.0.0.1,嘗試將localhost地址交換為ES的本地dns地址,例如
#URI of Elasticsearch; elastic works as well
com.graphaware.module.ES.uri=elastic
#Port of Elasticsearch
com.graphaware.module.ES.port=9201
