Question

最近我试图学习Apache Solr，但是我在运行它时遇到了一些问题。

要安装Solr我正在使用本指南：Solr Install

在runnig /opt/solr# java -jar start.jar之后没有太多事情发生。

7688 [searcherExecutor-5-thread-1] INFO  org.apache.solr.core.SolrCore  – QuerySenderListener done.
7688 [searcherExecutor-5-thread-1] INFO  org.apache.solr.handler.component.SpellCheckComponent  – Loading spell index for spellchecker: default
7689 [searcherExecutor-5-thread-1] INFO  org.apache.solr.handler.component.SpellCheckComponent  – Loading spell index for spellchecker: wordbreak
7689 [searcherExecutor-5-thread-1] INFO  org.apache.solr.handler.component.SuggestComponent  – Loading suggester index for: mySuggester
7691 [searcherExecutor-5-thread-1] INFO  org.apache.solr.spelling.suggest.SolrSuggester  – reload()
7692 [searcherExecutor-5-thread-1] INFO  org.apache.solr.spelling.suggest.SolrSuggester  – build()
7723 [searcherExecutor-5-thread-1] INFO  org.apache.solr.core.SolrCore  – [collection1] Registered new searcher Searcher@689e8096[collection1] main{StandardDirectoryReader(segments_1:1:nrt)}

它注册了一个新的搜索者，但是http://192.168.0.109:8983/solr没有运行...我得到ERR_CONNECTION_TIMED_OUT有什么想法吗？ Apache的默认欢迎页面工作正常。我在Oracle VM VirtualBox上运行它

现在我已尝试使用本指南：https://lucene.apache.org/solr/guide/7_0/installing-solr.html

这就是我所做的：

solr@hubert:~/solr/solr-7.3.0$ bin/solr start
*** [WARN] *** Your open file limit is currently 1024.
 It should be set to 65000 to avoid operational disruption.

一切似乎都很好，但我仍然无法在http://192.168.0.109:8983/solr运行我的Solr控制台（正如我所说，默认的apache网站运行正常）

Answer 1

ssh hubert@hubert -L 8983:192.168.0.109:8983 -p22

此命令和重启服务器解决了我的问题
