I am having some problems with the Nginx rewrite algorithm for WordPress.

I am using this for the rewrite and it works good;

    server_name www.domain.com domain.com;
    if ($host != 'domain.com') {
    rewrite ^/(.*)     http://domain.com/$1 permanent;
    } 

it makes this url;

http://domain.com/?author=1 

to this;

http://domain.com/author/username/

which is good but with an url like this;

http://domain.com/?author=1&type=like

it makes it;

http://domain.com/author/username/?type=like

and i am not getting any error but the query is not working.

What i am missing?

The correct Nginx rewrite rules for WordPress are:

location / {
        try_files $uri $uri/ /index.php?q=$uri&$args;
    }

This sends everything through index.php and keeps the appended query string intact.

If your running PHP-FPM you should also add this before your fastcgi_params as a security measure:

location ~ \.php {
        try_files $uri =404;

      //  fastcgi_param ....
      //  fastcgi_param ....

      fastcgi_pass 127.0.0.1:9000;
}
  • Chris thank you. Can you look at my whole code , is it looks correct right now? pastebin.com/DiMc6YtD ALSO where should i add the try files uri 404 in this? thanks. – boranb Nov 15 '11 at 1:05
  • no this is giving me duplicate cause i have already have location php. can you help chris? – boranb Nov 15 '11 at 1:20
  • okat i combined it like that and now everything works fine; pastebin.com/fuKwuCe1 but can you look at my whole code and tell me if i have any security issues? thanks – boranb Nov 15 '11 at 1:28
  • Change line 70 to try_files $uri = 404; See Nginx 0 day exploit for more info. – Chris_O Nov 15 '11 at 1:48
  • thank you very much chris! by the way the site you give is adding 403 not 404. what is the difference? – boranb Nov 15 '11 at 2:15

Please be aware that the & character between $uri '&' $args is very important, as it will partially work without it, but will fail in some cases.

Correct:

location / {
    try_files $uri $uri/ /index.php?q=$uri&$args;
}

Wrong:

location / {
    try_files $uri $uri/ /index.php?q=$uri$args;
}

The wrong method will manage to handle multiple args:

https://example.com?myvar=xxx&secvar=xxx // Will work

But fail if only one arg is passed:

https://example.com?myvar=xxx // Will NOT work

This made it really hard to find the typo for me, but at least I learned something new ^^
