elasticsearch - OpenEDX FullStack中的Elasticsearch出现错误

Question

我在Ubuntu 12.04上安装了fullstack open edx，然后使用fork edx-platform repo。完成后，elasticsearch不能用于查找类(class)。它始终显示“我们找不到任何结果”消息。

我在elasticsearch.log上检查日志，遇到此错误。

这是集群状态。

vagrant@precise64:/etc/elasticsearch$ curl -XGET 'http://localhost:9200/?pretty=true'

我该如何解决此错误？

Answer 1

当有人通过指定端口9300而不是端口9200来错误配置Elasticsearch REST客户端时，通常会发生此错误。检查在192.168.33.1上运行的客户端的配置，并确保它使用9200。
