NGINX Config PHP Trouble - nginx

Question

I am relatively new to NGINX, I admit (less than 24 hours), but, I got it basically configured. I'm setting up a site for a friend, and I saw an example of some code that uses subdomains like in the code below. But, in the subdomain, PHP won't work. It just asks me to download the file if I go to "subdomain.domain.tld", but, if I go to "subdomain.domain.tld/index.php", it says "No input file specified." The subdomain is phpmyadmin, by the way.
server {
listen 80;
server_name irc.physibots.info;
rewrite (.*) http://physibots.info:3989;
}
server {
listen 80;
server_name "~^([a-z]+)?.physibots.info";
root /home/virtual/physibots.info/subdomains/$1;
index index.php index.html index.html;
location / {
autoindex on;
}
location ~ \.php {
try_files $uri /error.html
fastcgi_index index.php;
fastcgi_pass unix:/tmp/php.socket;
include fastcgi_params;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
#server {
# listen 443;
# server_name localhost;
#
# charset utf-8;
#
# ssl on;
# ssl_certificate
server {
listen 80;
server_name physibots.info default;
root /home/virtual/physibots.info/public_html;
index index.php index.html index.html;
location / {
autoindex on;
}
location ~ \.php {
try_files $uri /error.html
fastcgi_index index.php;
fastcgi_pass unix:/tmp/php.socket;
include fastcgi_params;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}

Answer 1

Move the try_files to your location / { } block and change it to try_files $uri $uri/ /index.php;
location / {
autoindex on;
try_files $uri $uri/ /index.php;
}
location ~ \.php {
fastcgi_index index.php;
fastcgi_pass unix:/tmp/php.socket;
The rest looks surprisingly good for a beginner. :)
Also- make sure you're testing with curl and not a web browser or you'll constantly fight caching.
