當(dāng)我運(yùn)行以下命令更新 Solr 索引時：sh [dspace]/bin/dspace index-discoveryDSpace的安裝目錄在哪里[dspace]，我得到以下錯誤：Exception: Expected mime type application/octet-stream but got text/html. <!doctype html><html><head><title>HTTP Status 500 – Internal Server Error</title><style type="text/css">h1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} h2 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:16px;} h3 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:14px;} body {font-family:Tahoma,Arial,sans-serif;color:black;background-color:white;} b {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;} p {font-family:Tahoma,Arial,sans-serif;background:white;color:black;font-size:12px;} a {color:black;} a.name {color:black;} .line {height:1px;background-color:#525D76;border:none;}</style></head><body><h1>HTTP Status 500 – Internal Server Error</h1><hr class="line" /><p><b>Type</b> Status Report</p><p><b>Message</b> {msg=SolrCore 'search' is not available due to init failure: Error opening new searcher,trace=org.apache.solr.common.SolrException: SolrCore 'search' is not available due to init failure: Error opening new searcher at org.apache.solr.core.CoreContainer.getCore(CoreContainer.java:745) ...

將錯誤堆棧跟蹤轉(zhuǎn)換為 HTML 后，我發(fā)現(xiàn)文件的權(quán)限[dspace]/solr/search/data/index/segments_p阻止進(jìn)程訪問它。該文件的所有者是root，我以非 root 用戶身份使用 Eclipse 運(yùn)行 Tomcat，因此我使自己成為該文件的所有者：
chown myself:myself [dspace]/solr/search/data/index/segments_p
然后重新啟動 Tomcat，并重新運(yùn)行命令：
sh [dspace]/bin/dspace index-discovery
它做得很完美。
