在ubuntu 12.04版本下搭建LEMP環境，參考網路教學設定一步步下來，發現存取index.php一直報404 NOT FOUND 的錯誤（如果將檔案名稱改回index.html則可以正常存取），請問該如何解決？
php相關設定檔中已經設定了cgi.fix_pathinfo=0和listen = /var/run/php5-fpm.sock
nginx設定資訊如下：
<code>server {
listen 80;
root /vagrant/www/;
index index.php index.html index.htm;
server_name localhost;
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/www;
}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}</code>
