任何帮助都将不胜感激。

Answer 1

由于不干净的关闭，write.lock文件可能出现在solr/{environment}/data/index目录下。删除write.lock文件将修复此问题。

Answer 2

即使write.lock不在场，我也有这个问题。下面是为我解决这个问题的原因：

1)删除整个/solr目录

2)运行ps -ef|grep solr以查看任何solr进程正在运行

3)为步骤2中的每个进程运行kill -9 [solr pid]

4)运行rake sunspot:solr:start，然后运行rake sunspot:solr:reindex

希望这能有所帮助！
