I don't know why I got this error every time I tried to open the page:
2013/04/06 17:52:19 [error] 5040#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET /info.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost:8080"
I resolved it, it was a configuration file issue, I added:
location ~ .php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}
