Question

I recently set up a Nginx server to host a wordpress install and am using Varnish as a reverse proxy in front of the server. Varnish is running on port 80, so I have set up Nginx to listen to 80 and redirect. Unfortunately on redirection, the port 8080 is appended to the nginx request.

Including port_in_redirect off seems to be the general solution to this problem, but it doesn’t appear to be working for me. I’ve attached the /sites-enabled/default config below. Am I doing anything wrong?! The php redirections seems to work fine, it’s only at location /where it fails.

/sites-enabled/default:

server { 
    listen 8080 default;
    server_name "" xxx.xxx.xxx.xxx;  #just using IP here (no domain yet)

    port_in_redirect off;
    server_name_in_redirect off;

    access_log  /var/log/nginx/localhost.access.log;


    location / {
            root   /var/www/site/html/;
            index  index index.php;
            try_files $uri/ $uri /index.php?q=$uri&$args;
    }

    location ~ .php$ {

            fastcgi_pass   backend;

Actually, just sorted it. Simple error – in the WordPress admin site wp-admin > Settings > WordPress address (URL) and Site address (URL) both had the port 8080 in the URL! Hence the redirection. The above setup works fine like this.

If that doesn’t solve your problem a one tip I learned was to add print_r($_SERVER["SERVER_PORT"]); in your index.php to ensure you are getting the correct port (80 in my case) set from fastcgi.

Hopefully this simple step can save someone some time!
