Dostęp do ścieżki "/ etc/mono/registry" jest zabroniony

Question

Po uruchomieniu mojej strony ASP.NET MVC 4 na mojej stacji roboczej Fedora 20 za pomocą xsp4 (z MonoDevelop lub bezpośrednio) otrzymuję następujący wyjątek:

System.Web.HttpRuntime.FinishWithException (wr={Mono.WebServer.XSPWorkerRequest}, e={System.Web.HttpException: ---> System.Web.HttpException: The pre-application start initialization method Start on type System.Web.WebPages.PreApplicationStartCode threw an exception with the following error message: Exception has been thrown by the target of an invocation. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: An exception was thrown by the type initializer for <Module> ---> System.Security.SecurityException: No access to the given key ---> System.UnauthorizedAccessException: Access to the path "/etc/mono/registry" is denied.

Sprawdziłem to i nie ma pliku registry lub folder w /etc/mono/. Nie mogę też znaleźć tego w żadnym podfolderze, jak mogę rozwiązać to pytanie?

biegnę Fedorę 20 z najnowszej 3.15.6 jądra

mam inny setup w Ubuntu 14.04 LTS i że działa, więc to może być coś z wersji mono, czy może ja "brakuje mi jakiejś biblioteki?

Answer 1

Okazuje się, że po prostu tworząc folder przy użyciu mkdir

sudo mkdir /etc/mono/registry

i ustawienie odpowiednich uprawnień za pomocą chmod

sudo chmod uog+rw /etc/mono/registry

załatwia sprawę.

Jednak nadal nie rozumiem, gdzie taki folder jest ukryty w Ubuntu i dlaczego nie trzeba go tam tworzyć, a także dlaczego nie jest tworzony automatycznie podczas instalacji.

Answer 2

Można ustawić MONO_REGISTRY_PATH pkt do katalogu, który można kontrolować:

bash mkdir my-registry MONO_REGISTRY_PATH=`pwd`/my-registry xsp4
