Config Problem for Wordpress 2.5

thuss · April 12, 2008, 11:25pm

I am currently using Nginx to serve images only, but I have written a
script to launch the Nginx process, and php-cgi processes needed to run
Wordpress. I don’t seem to have the cofiguration correctly written, and
I’m not sure where I am making my error, so I could use some help. I
also don’t use the wp-cache, or Supercache plugins. I am running a
RedHat 5 Enterprise Server. Here is my configuration:

server {
    listen       my_ip_address:80;
    server_name  www.mydomain.com mydomain.com;
    error_page  404              http://www.mydomain.com/e404.php;

location / {
root /var/www/mydomain;
index index.php index.html index.htm;
if (!-e $request_filename) {
rewrite ^(.*)$ /index.php?q=$1 last;
}

     valid_referers none blocked images.google.com;
        if ($invalid_referer) {
        # return   404;
                    rewrite  ^(.*)$  http://www.mydomain.com/;
                    }
    deny blocked_ip_address;
    allow all;

   }

location ~ .php$ {
   fastcgi_pass  localhost:9999;
   fastcgi_index index.php;
   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 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;
   fastcgi_param SCRIPT_FILENAME

/var/www/mydomain$fastcgi_script_name;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
}

Ok, but what is the problem/error that you’re seeing?

location ~ .php$ {

this stuff in an include file for easier maintenance:

   fastcgi_param SERVER_NAME $server_name;
   fastcgi_param SCRIPT_FILENAME
/var/www/mydomain$fastcgi_script_name;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;

And be sure to notice that you just opened up a HUGE hole in that ANY
.php file on the filesystem is now executable. This means if you have
an upload dir then if someone can upload a file with a .php extension to
it then they can point their browser to it and trigger the rule above to
execute that file… ugg

Limit the regexp to only trigger on dirs that you expect php scripts to
be in - OR - setup a location for the upload dir with a break in it to
take precedence over the .php rule.

The stuff above looks basically ok - you need to post your error
messages to get more help

I am getting a 404 error.

Actually

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

is better too, then you can put it in an include. Otherwise, each
virtual host’s path needs to be hardcoded (and it doesn’t need to be!)

Just make sure the “root” of your vhost has the ending slash/; - I
stumbled across that one.

Also fastcgi_pass might be different per vhost (different fastcgi
pools, based on user ID for example) - basically, put everything
that’s the same in an include, and keep only the specific stuff
outside of it. I agree with Ed but wanted to point out a couple
exceptions

Still getting the same 404 error with those rewrite rules. I am not
using wp-cache or supercache.

You need some rewrite rules.

if (!-e $request_filename) {
rewrite ^.+/?(/wp-.) $1 last;
rewrite ^.+/?(/..php)$ $1 last;
rewrite ^(.+)$ /index.php?q=$1 last;
}

have you tried this?

other ideas/links:
http://aleksandarsavic.com/nginx-and-wordpress-setup-clean-seo-friendly-urls/
http://elasticdog.com/2008/02/howto-install-wordpress-on-nginx/

Typically WP installs have basically “if file does not exist, go
through /wordpress/index.php” or wherever your wordpress physical
directory resides.

    if (!-e $request_filename) {
        rewrite ^(.+)$ /index.php?q=$1 last;
    }

If that stuff doesn’t work, please post your config (edit out the
hostnames if you wish) you might have conflicting rules or something.
