I am really stuck.

I have been trying to get my server configured, I have nginx up and running and virtualmin but php just will not work, every time i request a php file it wants me to download the file.

Heres my config:

user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;


events {
worker_connections 1024;
}


http {
include /etc/nginx/mime.types;
default_type application/octet-stream;

log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

access_log /var/log/nginx/access.log main;

sendfile on;
#tcp_nopush on;

keepalive_timeout 65;

#gzip on;

include /etc/nginx/conf.d/*.conf;
server_names_hash_bucket_size 128;
server {
server_name test1.com www.test1.com;
listen 192.168.1.10;
root /home/test1/public_html;
index index.html index.htm index.php;
access_log /var/log/virtualmin/test1.com_access_log;
error_log /var/log/virtualmin/test1.com_error_log;
location ~ ^/~(.+?)(/.*)?$ {
alias /home/$1/public_html$2;
index index.html index.htm;
autoindex on;
}
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_FILENAME /home/test1/public_html$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;

fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass localhost:9001;
}
listen 192.168.1.10:443 default ssl;
ssl_certificate /home/test1/ssl.cert;
ssl_certificate_key /home/test1/ssl.key;
}
} include /etc/nginx/sites-enabled/*;


Any ideas?

Thanks
