如有任何帮助，我们将不胜感激。

Answer 1

由于不正常关机，

write.lock 文件可能存在于 solr/{environment}/data/index 目录下。删除 write.lock 文件将解决问题。

Answer 2

即使 write.lock 不存在，我也遇到了这个问题。这是为我解决的问题：

1) 删除整个/solr目录

2) 运行 ps -ef|grep solr 查看任何 solr 进程运行ning

3) 运行 kill -9 [solr pid] 对于步骤 2 中找到的每个进程

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

希望对您有所帮助！
