I'm having trouble configuring nginx to return the url I want. I'd like http://domain.com/blah?abc=e9800ecf8 to return http://domain.com/createpage.php?abc=e9800ecf8, i.e. it preserves the abc variable in $_GET

createpage.php is sitting in /www/webroot, and blah doesn't exist. How do I do this?

Here's my server block of the config file (obviously, not doing what I want):

server {
    root /www/webroot;
    index index.html;

    location / {
        index index.html;
    }
    location = /blah {
      return 301 /createpage.php;
    }
}

    location / {

        if ($request_uri ~ "^/blah\?abc=([a-z0-9]+)$") {
            return 301 /createpage.php?abc=$1;
        }

    }

  • I presume you meant [a-z0-9] ? It's still giving 404s after loading the configuration file, even if I just try to return 301 index.html.

  • @Escher Yes. What does your error log says ? index.html is not a valid URI. Btw, is it your only server block ? Because if not you need to define the server_name directive according to your domain.

  • Error log is empty. Access log is 127.0.0.1 - - [22/Mar/2015:00:10:26 +0100] "GET /blah?abc=a1723 HTTP/1.1" 404 177 "-" "Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:36.0) Gecko/20100101 Firefox/36.0" i.e. you can see that I'm testing it on a small test server before it goes on the production one (so server_name is not needed for the moment; I'm trying to have the simplest config file possible to isolate the problem. You're right about the URI, I changed it to / and it loads the index page as intended.

  • @Escher Well there's no point it would not work except if the server_name directive doesn't match because you have more than one server block loaded by your configuration or you did not reload nginx or you are have typos somewhere.

  • Found the error as I was commenting out line by lin: something in /etc/nginx/sites-enabled/* was interfering. The 301 return works, however it just shows me my php code, rather than passing it through the PHP interpreter module. I guess I need to work on the PHP FPM block now. Thanks for the solution.
