无法连接到http://localhost:9200上的弹性搜索

Question

我试图安装ELK (此资源https://www.howtoforge.com/tutorial/elasticsearch-and-kibana-installation-and-basic-usage-on-ubuntu-1604/)，但当我打开http://localhost:5601浏览器并使用http://localhost:5601 URL测试其安装是否正确时，我收到两个错误

​

我测试所有响应Elasticsearch: Failed to connect to localhost port 9200 - Connection refused，但没有工作，这是我的elasticsearch.yml

# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
network.host: 127.0.0.1:5601
#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
#

当我运行sudo systemctl status elasticsearch时，我得到了失败的结果

这是我的日志

我怎么才能解决这个问题？

Answer 1

我可以看到您的elasticsearch.yml并识别出一些更正，您可以尝试重新启动弹性搜索实例。

1. network.host: 127.0.0.1

1. 弹性搜索使用默认的http端口号9200，如果在单机上运行多个es实例(实践)，则可以按递增顺序定义http端口号。它的范围从9200到9299.

#http.port: 9200 ->您可以对单个实例进行注释/取消注释，这并不重要。
