【问题描述】：

所以我在 Windows 共享主机上的 Umbraco 7 实例上遇到了异常。似乎在任意时间后，Lucene Index（我不直接调用其 API）出现问题，并且应用程序进入错误状态，直到我刷新应用程序池。任何帮助将不胜感激。

【问题讨论】：

网站是否负载均衡或托管在 Azure 上？
不是。它正在为 windows 使用 godaddy 共享主机。
@JulesMeyer，我也看到了同样的情况，而且它不仅限于 GoDaddy。这里有更多信息（事实上，我在帖子中链接到你的问题）：our.umbraco.org/forum/getting-started/installing-umbraco/…

标签： asp.net-mvc lucene umbraco umbraco7

【解决方案1】：

Azure 网站使用远程文件系统，这可能会对 Lucene 造成严重破坏，我们已经多次看到此错误。我只能假设 Godaddy 也为他们的 IIS 网站使用远程文件服务器。

基本上，解决方案是在本地临时 asp.net 存储上运行 Umbraco lucene 索引。在最新版本的 Umbraco (7.2.8+) 中，此功能内置于核心中，您可以为索引器和搜索器使用 LocalOnly 配置标志，例如：

  <add name="InternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"
       supportUnpublished="true"
       supportProtected="true" 
       analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net"
       useTempStorage="LocalOnly"/>

  <add name="InternalSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"
       analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net" 
       useTempStorage="LocalOnly"/>

如果您使用的是旧版本的 Umbraco，您可以使用名为 TempStorage 的自定义库：https://github.com/Shazwazza/UmbracoExamine.TempStorage

【讨论】：

有趣的是我迄今为止看到的最实质性的回应。我相信我目前在 7.2.4 上，但这绝对值得升级几个小版本来尝试。我让你知道情况如何。
