Nginx + PHP-FPM = File not found

N

nx

I've just installed nginx, got it working, but I can't get my index.php to resolve.

I was getting 403 errors until I changed permissions, and now I get 404 errors.
The 403 is in /var/log/nginx-error.log and 404 in /var/log/nginx-access.log.
So nginx is working fine.

But I'm not sure if php-fpm is working.

To test I comment out the block in the config that 'passes the PHP scripts to FastCGI server listening on 127.0.0.1:9000'.
Nginx then asks me to open/save the index.php it otherwise should be rendering as html after php-fpm/fastcgi executes the php.
But I can't seem to configure this block (uncommented) to get php-fpm to work and send back html to nginx.

I installed from source so I could use the third party auth digest module (which isn't working yet), so user, pid, and some other directives were configured then. The prefix I set was /usr/local/etc/ningx.

Here's my config:
Code: 
#user  nobody;
worker_processes  2;mydomain

error_log  /var/log/nginx-error.log  warn;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
    use kqueue;
}


http {
    include       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  off;

    server_tokens off;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  5;

    port_in_redirect off;

    #gzip  on;

    server {
        listen       8082;
        server_name  www.mydomain.com;
        server_name_in_redirect off;

        auth_digest_user_file /usr/local/www/passwd.digest;
        location /private{
        auth_digest 'These are not the interwebs you are looking for';
        }

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

        location / {
            root   /usr/local/www/mydomain.com/public;
            index  index.php;
        }

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
            root           /usr/local/www/mydomain.com/public;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

    }

}

I've tried setting:

Code: 
fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;

as

Code: 
fastcgi_param  SCRIPT_FILENAME  /usr/local/www/mydomain.com/public$fastcgi_script_name;

and I've tried adding a trailing slash to end of root dir's but still no joy.


Here's the included fastcgi_params file:

Code: 
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_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

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;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

fastcgi_connect_timeout 60;
fastcgi_send_timeout 180;
fastcgi_read_timeout 180;
fastcgi_buffer_size 128k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;

I've tried turning fastcgi_intercept_errors on; but this doesn't show any more error info.


Can anyone see anything I've missed?

I installed following these howtos:
http://bin63.com/how-to-install-nginx-and-php-fpm-on-freebsd
http://interfacelab.com/nginx-php-fpm-apc-awesome/

and I've checked my config against the nginx docs.

The things I can think I've done wrong is not installing PHP with CLI, as per the first link, not enabling php-fpm, or I've screwed up a path in nginx.conf (above).

I tried reinstalling PHP with CLI, ps -aux gives the same output, and I still get a 404.

So it appears PHP is working (as php-fpm unless I'm mistaken) and nginx is obviously working.

Anyone have nginx + php-fpm setup and know how I can debug/fix this?
 
I've made some progress... mydomain.com is now showing:

Code: 
Access denied

If I turn php-fpm off:

Code: 
/usr/local/etc/rc.d/php-fpm stop

mydomain.com gives 502 Bad Gateway.

So php-fpm and nginx are working - just not as they should :\

To get this progress, here's my ammended php-fpm block at bottom of nginx.conf

Code: 
        location ~ \.php$ {
                include fastcgi_params;
                fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                root           /usr/local/www/mydomain.com/public;
                fastcgi_index  index.php;
                if (-f $request_filename) {
                    fastcgi_pass 127.0.0.1:9000;
                }
        }

I've found this user with same issue posting in the nginx forum, but his fix isn't working for me:

http://forum.nginx.org/read.php?3,197023

If anyone has had problems getting PHP executed by php-fpm and rendered as html by nginx, and possibly got the Access denied page, please help!
I've wasted a few hours on this today.
 
I think I may have found the issue and it is permissions.

But I'm not sure how to assign them as per this excerpt:

This effectively means that not only should the file have read permission, but the entire directory structure should have execute permission so that the PHP user can traverse the path. An example of this:

Say you have an index.php file in /var/www. /var/www/index.php must have read permission and both /var and /var/www must have execute permissions.

from http://blog.martinfjordvald.com/2011/01/no-input-file-specified-with-php-and-nginx/

I have nginx running as user and group webserver, and part of webadmin group, which has read + execute group permissions and owns (webadmin:webadmin) the documentroot dir down.

How would I extend this to -R /usr/local/www/mydomain.com/ without changing root:wheel as owner of everything else in /usr/local/www/ and all subdirectories of?

Or am I misreading that quote?
 
I'm going around in circles...

If I turn off php-fpm:

Code: 
/usr/local/etc/rc.d/php-fpm stop

nginx shows page with:

Code: 
503 Bad Gateway

If turn php-fpm on again, nginx shows page with:

Code: 
Access denied.

and /var/log/nginx-access.log shows a 430 Forbidden:

Code: 
GET / HTTP/1.1" 403 25

I've read forum posts that say this is due to a setting in /usr/local/etc/php-fpm.conf:

Code: 
security.limit_extensions =

which should have all extensions used in the location index parameter:

Code: 
location / {
            root   /usr/local/www/mydomain.com/public;
            index  index.php;

eg

Code: 
security.limit_extensions = .html .php

with the default being .php if this directive is commented out.

I've tried with it commented out, uncommented with .php, and with .html and .php (while adding index.html to the index parameter).

And it hasn't fixed this issue.


I've set all permissions on the documentroot (root) liberally for testing to 777.

I've turned autoindex on in the http 'stanza' (not shown in my config above) to see if ngnix is seeing the right directory.

If the root is set to html, which is the example directory included in the nginx directory, then it shows an index of that directory's files.

But this isn't working for the documentroot that I set /usr/local/www/mydomain.com/public

So my guess is this really is a permissions problem.

I just can't get them right.

Will anyone ever read this thread and help???
 
You mean the auth digest?

I have that working now..., but yes I did disable it to try to get php working.

Thanks
