I am facing a similar problem as this question where I am using Nginx as a proxy for Apache server (Ubuntu) running WordPress. The internal links of the website all give 301 redirects to localhost.

For instance, the link: wwww.example.com/internal-link redirects to localhost/internal-link which gives error 404.

The Apache configurations are as follow:

<VirtualHost *:80>
        <Directory /var/www/html>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
                Require all granted
        </Directory>

        ServerAdmin email@email.com
        ServerName example.com
        ServerAlias www.example.com
        ServerAlias *.example.com
        DocumentRoot /var/www/html
 ...

The Nginx configuration file is as follow:

server {
       # Where IP is server IP and example is the domain name
       listen       IP:80;
       server_name  static.example.com;

       location / {
           proxy_pass http://localhost:8480;
           proxy_set_header X-Real-IP $remote_addr;
       }

}

server {
       listen       IP:80;
       server_name  example.com;
       rewrite      ^ $scheme://www.example.com$request_uri redirect;
}

server {
        listen       IP:80;            # your server's public IP address
        server_name  www.example.com;   # your domain name

    location / {
        proxy_pass http://localhost:8020;
        proxy_set_header X-Real-IP $remote_addr;
    }
}       

The .htaccess is the default generated by WordPress:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

here is some of the records for Apache's access log:

10.0.2.2 - - [15/Jul/2016:07:11:31 -0400] "GET /link/ HTTP/1.0" 301 335 "-" "Mozilla/5.0 (compatible; Cliqzbot/1.0 +http://cliqz.com/company/cliqzbot)"
10.0.2.2 - - [15/Jul/2016:07:08:02 -0400] "GET /link/ HTTP/1.0" 404 5396 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:21.0) 

any idea what is causing this and how to fix it?

  • Is apache issuing the redirects or nginx? Please post your nginx configuration. – EEAA Jul 15 '16 at 20:13
  • @EEAA how can I check if Apache is issuing the redirect? I don't have access to nginx configuration – Rain Man Jul 15 '16 at 20:14
  • The redirects should be logged in the apache access_log. You're likely going to need to change your nginx configuration for this to work, though. – EEAA Jul 15 '16 at 20:15
  • Why are you using both Nginx and Apache? I run Nginx and PHP for Wordpress, Apache not required. What happens if you take away either Nginx or Apache? Nginx/Wordpress tutorial: photographerstechsupport.com/tutorials/… – Tim Jul 17 '16 at 5:19

    I was asking about the why. It would be useful to see a curl for a resource, and the corresponding entries in the Nginx and Apache logs. That will tell us where the 301 is coming from and will help narrow down how to fix it. – Tim Jul 22 '16 at 0:04

I use following NGINX server block to proxy_pass all requests to local Apache HTTP Server:

# cat /usr/local/etc/nginx/conf.d/apache24.conf 
server  {
    listen 80;

    location    /   {
        proxy_pass  http://127.0.0.1;
        proxy_set_header    Host    $host;
        proxy_set_header    X-Forwarded-For $remote_addr;
        proxy_set_header    X-Real-IP   $remote_addr;
        proxy_pass_header   server;
    }
}
# 

and Apache's HTTP Server VirtualHost configured normal way.

  • this should be placed instead of last server configuration in the file? I never worked with nginx so not sure – Rain Man Jul 21 '16 at 15:27
  • @RainMan I dont know how your environment setup, so I cannot tell you to replace anything there, but I would recommend you to make a backup before making any changes, but the idea is if you're using default nginx.conf and use include conf.d/*.conf; you can then place this into your conf.d and it should work) – alexus Jul 21 '16 at 15:32
