I'm struggling with the .NET alternative mono for Linux. Here is my meta data:
OS: Debian 7.6 alias Wheezy (as virtual machine; host: Windows 7 Pro SP1)
nginx v1.6.1 (installed from nginx repository)
mono v3.6.0 (compiled from source)
mono-fastcgi-server4 (installed from Debian repositories)
nginx works properly; I tested it without mono, so that shouldn't be the problem.
The problem occurs when I enable the fastcgi part within nginxserver config: I get a 502 Bad Gateway.
For your information, these are all the config files I edited so far. I think these are the important ones:
/etc/nginx/conf.d/default.conf
server {
listen 80;
server_name myserver.net;
root /var/www/myserver.net;
index index.html;
location / {
fastcgi_index index.html;
fastcgi_pass 127.0.0.1:9000;
include /etc/nginx/fastcgi_params;
}
}
/etc/nginx/fastcgi_params (original except these two lines):
fastcgi_param PATH_INFO "";
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
/etc/init.d/mono-fastcgi/myserver.net.webapp
<apps>
<web-application>
<name>myserver.net</name>
<vhost>*</vhost>
<vport>80</vport>
<vpath>/</vpath>
<path>/var/www/myerver.net/</path>
</web-application>
</apps>
mono-fastcgi-server4 startup-command (split to multiple lines for overview)
fastcgi-mono-server4
--appconfigdir /etc/init.d/mono-fastcgi
/socket=tcp:127.0.0.1:9000
/logfile=/var/log/mono/fastcgi.log &
I actually don't know, why the & has to be there at the end, but without it, the command won't work. Any suggestions?
I think this is all information I can share with you. If something is missing, please point it out, and I'll add the information ASAP.
EDIT: I forgot to add the fastcgi.log and nginx-logs:
