如何解决此问题？

Answer 1

您的solr网址无效。你也需要编写核心。默认情况下，核心是collection1。因此，在您的情况下，网址为http://localhost:8983/solr/collection1

Answer 2

Solr似乎没有运行 - 连接被拒绝表示某些东西无法联系它应该联系的任何东西。您的配置可能已损坏，或者您尚未启动Solr，或者您正在另一个端口上运行。

Apache Solr：我在Cygwin Terminal中运行了这个命令。 ./nutch crawl urls -dir newCrawl -solr http：// localhost：8939 / solr / -depth 10 -topN 10
