ABP Zero 5.3.0 (ASP.Net Core 2.0.2) 发布问题

在发布 ABP Zero 5.3.0，ASP.Net Core 版本 2.0.2 到 Win 2012 R2 服务器时，遇到一个奇怪的问题，发布到 IIS 后，打开站点报 500 错误。

 

查看站点下 “App_Data\Logs\Log.txt”，显示的错误详情如下

 1 ERROR 2018-04-21 12:02:23,413 [3    ] Microsoft.AspNetCore.Server.Kestrel      - Connection id "0HLD77HRIRUNH", Request id "0HLD77HRIRUNH:00000001": An unhandled exception was thrown by the application.

 先看到有一个路径信息，说站点下缺少“Plugins” 文件夹，于是手动增加了该文件夹，重新启动站点，还是报一样的错，就认为不是这个原因，还原现场我就把 “Plugins”

另外根据报错信息 “Could not load file or assembly 'Microsoft.AspNetCore.Hosting.resources, Version=2.0.2.0, Culture=zh-CN, PublicKeyToken=adb9793829ddae60'. 系统找不到指定的路径。”，怀疑是 AspNetCore.Hosting 版本差异引起的问题，因为之前服务器安装的是 DotNetCore.2.0.0-WindowsHosting.exe，所以我又下载了最新的 Asp.Net Runtime（ "AspNetCore.2.0.7.RuntimePackageStore_x64.exe"），但是安装完后再次运行站点还是同样的错误。

之后通过搜索了很多网站，也尝试了很多不同的解决方案都无效，为了得到更多的信息，修改了 web.config 中 stdoutLogEnabled="true"，但是日志文件夹 "logs"没有自动生成，在手动创建了 logs 文件夹后，刷新网站也没有日志写入该文件夹下，而  “App_Data\Logs\Log.txt” 日志里记录的还是同样的异常信息。

 

网络上已经找不到解决方案了，已经穷途末路。根据以上的情况综合分析后，我有一个假设，会不会是某些特别的权限问题导致的呢，于是我将站点文件夹拷贝到了另外一个用户自己创建的目录下，不再放 “C:\inetpub\wwwroot” 里。重启 iis 后，打开站点，还是500错误，但是 stdoutLog 日志文件生成，这印证了我的假设，日志的错误显示明确了很多，缺少 “Plugins” 文件夹。

 

在新的站点目录下添加了 “Plugins” 文件夹后，重新打开站点，看到了熟悉的画面，内心是无比的欣悦啊，耗时大半天总算解决了这个奇葩的问题。

 

 总结，在 “C:\inetpub\wwwroot”  下部署的站点，很容易出现莫名其妙的权限问题，即使是用 iis 运行账户的用户去创建的文件夹也会出现权限问题，所以为了避免这些奇怪的问题出现，建议将站点部署到 “C:\inetpub\wwwroot” 外的用户文件夹下。
