Forum: NGINX nginx + wordpress rewrite question

Hello,

This is a really basic question. I'm unfamiliar with nginx (didn't even 
know it existed until a couple days ago) and not a master at URL 
rewrites. I have been tasked with hooking up Wordpress to nginx. The 
basic setup was easy enough. However, I'm running into some problems 
with the rewrites. I've been asked to rewrite from the static permalink 
format...

"/blog/$postname$-$post_id$"   (e.g. /blog/my_blog_post_title-49) => to 
the standard "/blog/?p=N"

I've tried a bunch of variations, but I keep getting it wrong because 
the non-post content (css, images, etc.) are returning 404s. Does anyone 
have an example of how to do a nginx rewrite that does the above?

thanks for any suggestions,

Jaime Magiera

You should probably setup a separate location for the static content
(images, css, etc), that way your rewrite doesn't affect them.

Wordpress uses post_name for queries from the url.  Out of the box it
only supports hyphens and not underscores.  You need to also change
your permalink settings in wordpress admin Settings > Permalinks.

The rewrite only needs to use try_file conf as outlined in the
wordpress config on wiki.nginx.org.   That or:

error_page 404 /index.php?q=$uri;

You can probably do something like this at best:

/blog/my-blog-post-title-49
or
/blog/my-blog-post-title-49.html

Not sure whether this would help, but WP usually is able to handle
"rewriting" by itself.

I only need this config to get WP to work:

location /
 {
 if (!-e $request_filename) {
 rewrite ^.*$ /index.php last;
 }
 }

location ~ \.php$
 {
 fastcgi_pass (your php socket/port here);
 }

And WP has to be configured correctly in Settings > Permalinks (like 
what
Hone Watson said).

wordpress is pretty smart in handling rewrites

here's example for wordpress installation in a root of a domain:

server {
  listen 80;
  server_name my.blog.com;
  location ~ ^/.*\.php$ {
    root /srv/http/wordpress;
    fastcgi_pass 127.0.0.1:9100;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $request_filename;
    include fastcgi_params;
  }
  location / {
    index index.php;
    root /srv/http/wordpress;
    try_files $uri /index.php;
    expires max;
  }
}

inside a directory, it'd be either:

server {
 listen 80;
 server_name my.blog.com;
 location ~ ^/blog/.*\.php$ {
   root /srv/http/wordpress;
   fastcgi_pass 127.0.0.1:9100;
   fastcgi_index index.php;
   fastcgi_param SCRIPT_FILENAME $request_filename;
   include fastcgi_params;
 }
 location /blog/ {
   index index.php;
   root /srv/http/wordpress;
   try_files $uri /index.php;
   expires max;
 }
  location = /blog {
    rewrite ^ /index.php;
  }
}

and then create symlink /srv/http/wordpress/blog pointing to
/srv/http/wordpress;

or

server {
  listen 80;
  server_name my.blog.com;
  location ~ ^/blog/(.*\.php)$ {
    alias /srv/http/wordpress/$1;
    fastcgi_pass 127.0.0.1:9100;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $request_filename;
    include fastcgi_params;
  }
  location /blog/ {
    index index.php;
    alias /srv/http/wordpress/;
    error_page 404 = /index.php;
    expires max;
  }
  location = /blog {
    rewrite ^ /blog/index.php;
  }
}

No need for symlinks, and a million ways to do things.  Still need to
add in that supercache config I wrote like a year ago for someone but
I want to test it first :P~.

it doesn't cover when the wordpress installation is in
/some/where/wordpress and need to be accessible under
www.myweb.com/blog, not www.myweb.com/wordpress .

Actually, this one does:
http://wiki.nginx.org/Wordpress#Non-root_try_files_to_internal_location

You would just change the location to /blog instead of /wordpress.

Do I assume too much about the reader's understanding of location in
nginx and should I make this section more clear?

OK, I appreciate all your help. It seems I've messed things up even more 
now. While attempting to translate what you folks provided, I've now got 
a configuration that doesn't work right even with standard wordpress 
links. If I try to go to the default URL for the blog, I end up getting 
a download of the php instead of the page displaying (however, some 
other wordpress URLS work?). I'm really not getting nginx. Can someone 
perhaps point out what it is that I'm not getting. Taking this project 
over cold with no nginx experience is becoming a very frustrating 
experience.

OK, that would give me what's copied below. However, I'm still getting a 
download of the php when I navigate to /blog instead of the php content. 
Every other .php file in the wordpress directory is working. Any other 
thoughts? This is stumping me.

index           index.php index.html;
       location ~ \.php$ {
               fastcgi_index  index.php;
               fastcgi_pass   localhost:9000;
               fastcgi_param  SCRIPT_FILENAME
                      $document_root$fastcgi_script_name;
               include        /opt/nginx/conf/fastcgi_params;
       }

       location /blog {
               passenger_enabled off;
               index index.html index.htm index.php;
               try_files $uri $uri/ @blog;
       }

       location @blog {
               include        /opt/nginx/conf/fastcgi_params;
                fastcgi_index  index.php;
                fastcgi_param SCRIPT_FILENAME 
$document_root/blog/index.php;
                fastcgi_pass   localhost:9000;
        }
