我刚开始使用Nutch 1.11和Solr 5.3.1。
我想用 Nutch 抓取数据，然后用 Solr 索引并准备搜索。
我知道如何使用Nutch'sbin/crawl命令从网络上抓取数据，并成功地从我本地的网站上获取了大量数据。
我还在根文件夹Solr下使用以下命令在本地启动了一个新服务器，Solr
bin/solr start
files并使用以下命令在示例文件夹下启动示例核心：
bin/solr create -c files -d example/files/conf
我可以在管理 url 下面登录并管理files核心，
http://localhost:8983/solr/#/files
所以我相信我开始Solr正确，并开始使用命令将Nutch数据发布到：SolrNutchbin/nutch index
bin/nutch index crawl/crawldb \
-linkdb crawl/linkdb \
-params solr.server.url=127.0.0.1:8983/solr/files \
-dir crawl/segments
希望有了Solr5新的Auto Schema功能，我可以让自己平静下来，但是，我得到了以下错误（从日志文件复制）：

我记得这个
org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Expected mime type application/octet-stream but got text/html.
与Solr网址有关，但我仔细检查了我使用的网址127.0.0.1:8983/solr/files，我认为它是正确的。
有谁知道问题是什么？我在网上搜索，在这里，没有什么有用的。
注意：我还尝试了禁用Solr5's Auto Schema功能examples/files/conf/solrconfig.xml并替换examples/files/conf/managed-schema.xml为Nutch's 的方式conf/schema.xml，仍然遇到相同的错误。
更新：在尝试了DEPRECATED命令后bin/nutch solrindex（感谢Thangaperumal），之前的错误消失了，但又遇到了另一个错误：
bin/nutch solrindex http://127.0.0.1:8983/solr/files crawl/crawldb -linkdb crawl/linkdb crawl/segments/s1
