404 error on homepage when using Nginx proxying to Apache

by

I generally use Nginx to serve static content on my server, with Apache handling PHP content using PHP-FPM. However, I’m not able to get a WordPress blog homepage to display and I’ve tried all the configuration examples I can find on the web without much luck.

Here is my Nginx config:

server {

        listen   XXX.XXX.XXX.XXX:80;
        server_name wptest.mydomain.com;

    access_log  /var/log/nginx/testblog_access.log combined;
    error_log /var/log/nginx/testblog-error.log;

    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    location / {
                    proxy_pass http://127.0.0.1:80;
    }

    location = /50x.html {
            root   /var/www/nginx-default;
    }

    # No access to .htaccess files.
    location ~ /\.ht {
            deny  all;
    }

}

My Apache config is as follows:

<VirtualHost 127.0.0.1>
    ServerName wptest.mydomain.com
    ServerAdmin [email protected]
    LogLevel warn
    ErrorLog /var/log/apache2/testblog-error.log
    CustomLog /var/log/apache2/testblog-access.log combined

    Options +FollowSymLinks +ExecCGI -Indexes -MultiViews
    AddHandler php-fastcgi .php
    Action php-fastcgi /wordpress
    Alias /wordpress /var/www/wordpress
    FastCgiExternalServer /var/www/wordpress -host 127.0.0.1:9000
    RewriteEngine on

    DocumentRoot /var/www/wordpress
    DirectoryIndex index.php

                    <Directory />
                            DirectoryIndex index.php
                            AllowOverride All
                            Options +FollowSymLinks +ExecCGI +SymLinksIfOwnerMatch
                    </Directory>

                    <Directory /var/www/wordpress>
                            AllowOverride All
                            Options +FollowSymLinks +ExecCGI +SymLinksIfOwnerMatch
                    </Directory>
</VirtualHost>

I am not able to view “http://wptest.mydomain.com/” or “http://wptest.mydomain.com/wp-admin” but “http://wptest.mydomain.com/wp-login.php” does work. What am I doing wrong?

Version information:
+ OS: Debian 5/Lenny
+ Apache: 2.2.9
+ Nginx: 0.7.65
+ WordPress: 3.1.2

Both servers are listening to the same port. You have Nginx set to listen to 80 and nothing is set for Apache unless it’s in your ports.conf.

Your also proxy passing to Apache port 80 in your Nginx conf.

In the Nginx conf change

proxy_pass http://127.0.0.1:80;

to

proxy_pass http://127.0.0.1:9000;

change listen XXX.XXX.XXX.XXX:80; to listen 80;

In your Vhosts

add 

NameVirtualHost *:9000
Listen 9000

Above the <VirtualHost> tag or in the ports.conf file (If you have other vhost that don’t use Nginx add it to the top of your vhost. Change virtual host to look like this:

<VirtualHost *9000>
