Bad Gateway with nginx, mono and fastcgi on debian
I am struggling with an alternative mono.NET for Linux. Here is my metadata:
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 is working correctly; I've tested it without mono, so it shouldn't be a problem.
The problem occurs when I enable the fastcgi component in the nginxserver config: I get a 502 Bad Gateway.
For your information, all of these configuration files that I have 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 for 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 over multiple lines for review)
fastcgi-mono-server4
--appconfigdir /etc/init.d/mono-fastcgi
/socket=tcp:127.0.0.1:9000
/logfile=/var/log/mono/fastcgi.log &
I really don't know why I &
should be there at the end, but without it the command won't work. Any suggestions?
I think this is all the information I can share with you. If something is missing, please provide it and I will add the information as soon as possible.
EDIT: I forgot to add fastcgi.log and nginx-logs :
