elasticsearch-Ubuntu-拒绝连接
我已经在Ubuntu 14.04上安装了弹性2.2。我保留了elastic的默认初始设置,并且该实例可从localhost:9200到达该系统的弹性实例。
现在,当我尝试使用服务器的IP / DNS名称通过其他系统通过以下方式进行操作时:
curl -XGET "http://<IP_ADDRESS_UBUNTU_SERVER>:9200"
我收到如下错误:
Failed to connect to <IP_ADDRESS_UBUNTU_SERVER> port 9200: Connection refused
我尝试更改elasticsearch.yml文件中的几个参数并将其设置为:
network.host: 0.0.0.0http.port: 9200
但这并不能解决问题。我设置了与拒绝连接相同的错误。实际上设置上述参数并尝试使用localhost:9200从服务器进行访问也会产生连接超时错误。
现在需要配置什么,以便可以从外部访问此弹性实例?
编辑:我试图将Ubuntu服务器的IP地址设置为network.host,但在日志文件中看到以下错误:

回答:
这是由于配置文件中的错误引起的。我没有遵守YAML指南,却盲目地遵循弹性帮助文档。
网络和端口必须以YML格式指定,如下所示:
network: host: 0.0.0.0
http:
port: 9200
此后,重新启动弹性服务。如果出现问题,请参考弹性日志文件,并检查实例是否绑定到上述IP和端口9200。您还可以检查侦听IP /端口(netstat -l
-n)。必须有一个像这样的条目:
tcp 0 0 0.0.0.0:9200 0.0.0.0:* LISTEN
希望这对您有所帮助,并祝您搜索愉快。
