python - ckan datapusher/api/3/action/resource_show(由 : [Errno 111] Connection refused) error 引起

Question

我正在尝试安装 ckan 2.2.1 + pgsql 9.1 + solr 3.6 + rhel 6.6。

我设置文件存储和数据存储插件。我尝试在 ckan web 中使用“上传到数据存储”菜单。然后我得到了这个错误。

ckan，solr 运行良好。 8800 端口的数据推送器正在运行。

$ curl localhost:8800
{
  "help": "\n        Get help at:\n        http://ckan-service-provider.readthedocs.org/."
}

我的数据推送器是否遗漏了什么？谢谢。

我添加了我的ini

正如您在评论中注意到的，问题是数据推送器试图连接到错误的端口:

ConnectionError: HTTPConnectionPool(host='default.ckan.com', port=80): Max retries exceeded with url: /api/3/action/resource_show (Caused by : [Errno 111] Connection refused)

您已经找到了一个可能的解决方法:将 CKAN 的端口更改为 80。

作为替代解决方法，我发现将端口(与 [server:main] 部分中的 port 配置的端口相同)添加到 ckan。 site_url 使数据推送器使用它而不是默认的 HTTP 端口 (80)。因此，在您的情况下可能是:

ckan.site_url = http://default.ckan.com:5000

当然，这只是另一种可能的解决方法； 真正的解决方案是修复数据推送器，以便它从配置中正确读取端口...
