後，我改變我的應用程序名稱

Question

通常情況下我的應用程序在這裏位於我如何更新太陽黑子，Solr的路徑：

/數據/網站/電流/

但現在它的：

/數據/站點2 /電流/

我試圖腳本/控制檯進去，重新索引，並收到以下錯誤導致我相信，新的路徑是扔它關閉：

我該如何改變Sunspot-Solr的默認目錄？

Answer 1

這是因爲sunspot-solr gems沒有安裝在服務器上，因此這裏所有的調用gem錯誤。當我安裝我的寶石時，我也必須用一個pkill來殺死它的進程。

我跑

$> ps aux | grep solr 

看到它正在運行的過程，所以我跑了pkill的：

pkill -term -f '/usr/lib/jvm/sun-jdk-1.6/bin/java -Djava.net.preferIPv4Stack=true -Dsolr.solr.home=solr -jar start.jar' 

殺了它，並重新啓動它。問題解決了。
