当我运行以下命令来更新 Solr 索引时:
sh [dspace]/bin/dspace index-discovery
其中[dspace]是DSpace的安装目录，我收到以下错误:

最佳答案
将错误堆栈跟踪转换为 HTML 后，我发现文件 [dspace]/solr/search/data/index/segments_p 的权限阻止了进程访问它。该文件的所有者是 root 用户，我以非 root 用户身份使用 Eclipse 运行 Tomcat，因此我让自己成为该文件的所有者:
chown myself:myself [dspace]/solr/search/data/index/segments_p
然后重新启动 Tomcat，并重新运行命令:
sh [dspace]/bin/dspace index-discovery
做得很完美。
关于java - 更新DSpace Solr索引遇到此错误: SolrCore 'search' is not available due to init failure，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57541514/
