Nginx – Another PHP NGINX error: “No input file specified”

centosfastcginginxPHP

I looked through about 5 questions and blog posts already and tried everything they told me without luck. I can browse to www.example.com/phpinfo.php, but not www.example.com/index.php. I even went so far as to make phpinfo.php a symlink of index.php and phpinfo.php still works while index.php does not.

Nginx Config

[admin@web01 www]$ cat /etc/nginx/conf.d/example.com.conf

    # Document root

Error log

2014/01/24 10:37:52 [error] 8286#0: *15 FastCGI sent in stderr:
"Unable to open primary script: /var/www/sites/example.com/www/index.php
(No such file or directory)" while reading response header from upstream,
client: XXX, server: www.example.com, request: "GET /index.php HTTP/1.1",
upstream: "fastcgi://127.0.0.1:9000", host: "www.example.com"

Update

  1. Updated my config to include everything
  2. Added permissions for /, /var, /var/www, etc
  3. Turned off SELinux completely with no effect

Update #2

Removed the try_files line from the location ... .php$ line and edited php.ini's cgi.fix_pathinfo=0. Realized I hadn't restarted php-fpm this whole time. Magically working now! If you can explain why phpinfo.php was working the whole time and index.php was not (even though they resided in the same directory, and phpinfo.php was a symlink to index.php!!) you get the bounty.

Best Answer

Try adding this to your nginx.conf:

fastcgi_index index.php;

e.g. the relevant section of your nginx.conf file would look like this:

# Pass PHP scripts to FastCGI server
location ~ \.php$ {
    fastcgi_index index.php;
    include       fastcgi.conf;
    try_files     $uri =404;
    fastcgi_pass  127.0.0.1:9000;
}

What this does is tell fastcgi to use index.php if a file is not specified. For the record, I am using a patched nginx 1.2.9 (I changed ~* to ~ because that's how it looks in my nginx.conf)
