HTTP Status 500 - {msg=SolrCore ‘collection1’ is not available due to init failure: Could not load conf for core

具体错误如下:

具体解决方法就是Tomcat/webapps/solr/WEB-INF/web.xml这个文件里配置没改过来。如下：

如图标记出来的地方应该是放置solr服务器的solrhome的位置。
不过有的小伙伴改完之后还是不能成功的访问到solr页面。

然后网上步骤就是需要在solrhome下面新建一个solr.xml文件，内容如下：

<?xml version="1.0" encoding="UTF-8" standalone="true"?> 可是我这新建了之后还是不能访问到没办法，再回头看报错信息：

仔细看这里是 /usr/local/solr/collection1/conf/solrconfig.xml 这出了问题，找不到这个。我们来到此目录下：

于是我将web.xml中的路径明确了一下（以为我的solr的主要配置是在solrhome下面的solr文件夹下）
然后重启Tomcat，再次访问 http://ip:8080/solr
于是终于来到了这个期待的页面，（终于等到你,还好我没放弃。hh）

希望能帮到跟我一样刚接触solr的小熊熊们！
