How to get ASP.NET running on Apache on CentOS 7?

Question

I successfully installed Apache, Mono, XSP Server and MonoDevelop on a CentOS 7 machine, basically following http://www.mono-project.com/docs/getting-started/install/linux/#centos-fedora-and-derivatives (with added yum install -y xsp, and yum install -y monodevelop. Mono Develop works and I can create and run ASP.NET websites with it (via XSP Server).

But I need to integrate Mono with Apache. To do this I installed mod_mono (yum install -y mod_mono) and created a configuration for a test application via http://go-mono.com/config-mod-mono/. I changed the mono server version to 4 and added granting open access:

Alias /mono-test "/srv/www/mono-test"
MonoServerPath mono-test "/usr/bin/mod-mono-server4"
MonoDebug mono-test true
MonoApplications mono-test "/mono-test:/srv/www/mono-test"
<Location "/mono-test">
  Allow from all
  Order allow,deny
  MonoSetServerAlias mono-test
  SetHandler mono
  SetOutputFilter DEFLATE
  SetEnvIfNoCase Request_URI "\.(?:gif|jpe?g|png)$" no-gzip dont-vary
  # Allow open access:
  Require all granted
</Location>

<IfModule mod_deflate.c>
  AddOutputFilterByType DEFLATE text/html text/plain text/xml text/javascript
</IfModule>

I placed the file in /etc/httpd/confd with the name x-mono-test.conf, to be sure it is loaded after the default mod_mono.conf (content see at the end of this question).

The problem is that accessing a test aspx file in the Apache application (http://localhost/mono-test/test.aspx) results in a HTTP 503 - Service Unavailable. The Apache error log remains empty.

I would like to know what could be wrong or how I could find the source of this issue.

Content of mod_mono.conf:

<IfModule !mod_mono.c>
    LoadModule mono_module /usr/lib64/httpd/modules/mod_mono.so
</IfModule>

<IfModule mod_headers.c>
    Header set X-Powered-By "Mono"
</IfModule>

Solution

I think you miss one set in the configuration of apache with mono. I strongly suggest you to check this guide is for Ubuntu. I tried and it works fine with xsp and apache. I test some examples and work fine for everything except WCF (svc). Apparently, that support it still with a lot of problems in mono 2.10.

I think the problem could be that the virtual host is not active. But, that is a simple hunch.
