Wordpress (single blog installation) and nginx

advany · December 13, 2007, 9:21am

Hi guys,

I am running php with nginx, with fastcgi. But instead of heaving my
urls
like www.myblog.com/index.php/bla/bla I would like
www.myblog.com/bla/bla http://www.myblog.com/bla/bla.

With the setup at the end of the mail, it redirect if a file can’t be
found
to index.php, but I get the content of index.php back. (So if I go to
www.myblog.com/bla/bla).

But I also have other requests that should not be rewritten (directories
and
files in the root directory). Is this possible? to redirect only if
www.myblog.com/bla/bla doesn’t exist to a normal request to the root
directory and send that to the fastcgi process?

I really love nginx, and thanks to this mailinglist I didn’t need much
help.
But most rewrite rules are written wordpress MU (multiuser) and not
wordpress redux. I just need to to rewrite all request that do not
exists to
index.php and pass this to fastcgi.

I did get this working one time… but I can’t figure out how I did it :S

server {
listen 80; # Replace this IP and port with the right
ones for your requirements
server_name www.myblog.com

    #charset koi8-r;

    #access_log  logs/host.access.log

    location ~*

^.+.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|mov)$
{
root /var/www/blog;
}

    error_page  404 /index.php;

    location ~ \.php$ {
      include        /etc/nginx/fastcgi.conf;
      fastcgi_pass

127.0.0.1:8888;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME
/var/www/blog/$fastcgi_script_name;
}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}

 }

How does wordpress find what URI you request ?
I know that wordpress may use REQUEST_URI (it should already set
in /etc/nginx/fastcgi.conf):

fastcgi_param REQUEST_URI $request_uri;

The second way (I do not know whether Wordpress use it) is PATH_INFO:

  location / {
       root /var/www/blog;
       error_page  404 /index.php;
  }

  location ~ \.php$ {
       include        /etc/nginx/fastcgi.conf;
       fastcgi_pass 127.0.0.1:8888;
       fastcgi_param  PATH_INFO        $request_uri;
       fastcgi_param  SCRIPT_FILENAME

/var/www/blog/$fastcgi_script_name;
}

  location ~*

By the way, what method does work - REQUEST_URI or PATH_INFO ?

```
  error_page  404 /index.php;

```
  error_page  404 = /index.php;

There seems to be an other problem, it doesn’t pass the params so…
blog.domain.com/?page_id=2 doesn’t work, where
blog.domain.com/index.php?page_id=2 does work, I added both
requirest_uri
and path_info, but no success. Can’t find much on it on the mailinglist.

Greetz,

Abdul

I was on nginx 5.26… gave a error, upgraded to 5.33 and getting the
same error…

2007/12/15 19:56:07 [emerg] 28620#0: unknown “arg” variable

even tried

error_page 404 = /index.php?$arg;

error_page 404 = /index.php?$args;

Yes, I missed: it should be “$args”.
However, you need 0.6.x branch to use it.

There’s another way:

You should inline /etc/nginx/fastcgi.conf to change
fastcgi_param QUERY_STRING $query_string;
to
fastcgi_param QUERY_STRING $orig_args;

and use following configuration (important places are marked by “!”):

location / {
     root /var/www/blog;

! set $orig_args $args;
error_page 404 = /index.php;
}

location ~ \.php$ {
     fastcgi_pass 127.0.0.1:8888;
     fastcgi_param  SCRIPT_FILENAME

/var/www/blog/$fastcgi_script_name;

! fastcgi_param QUERY_STRING $orig_args;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;

     fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
     fastcgi_param  REQUEST_URI        $request_uri;
     fastcgi_param  DOCUMENT_URI       $document_uri;
     fastcgi_param  DOCUMENT_ROOT      $document_root;
     fastcgi_param  SERVER_PROTOCOL    $server_protocol;

     fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
     fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

     fastcgi_param  REMOTE_ADDR        $remote_addr;
     fastcgi_param  REMOTE_PORT        $remote_port;
     fastcgi_param  SERVER_ADDR        $server_addr;
     fastcgi_param  SERVER_PORT        $server_port;
     fastcgi_param  SERVER_NAME        $server_name;

     # PHP only, required if PHP was built with

–enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
}

advany · December 15, 2007, 11:35pm

haha, yeah, good hack, but know its not passing the params when I have
like www.blog.com/admin/index.php?edit=5

Is there some coditional coding I can do?

If $orig_args
fastcgi_param QUERY_STRING $orig_args;
else
fastcgi_param QUERY_STRING $args;

…

You need to move

    set   $orig_args   $args;

to a server level.

advany · December 13, 2007, 4:00pm

REQUEST_URI makes it work.

Everythings works great, I will write this up for future reference for
myself and others, and refer to you and this mailinglist. I will mail
the
link.

Thanks for your help and nginx!,

That doesn’t work, it just handles the admin/index.php?bla=bla but not
/?bla=bla and give the args to index.php

Also tried to remove from server level en put in both location blocks,
doesn’t work…

I can life with this but would be good if I could figure it our for
the 5.xxbranch…

You should use “set $orig_args $args;” on server level only.

It will be merged in 0.5.35, probably before New Year.

Jups, thats what I did, Ill wait for 0.5.35.

For single blog installations I’ve just used this after the location of
static files:

if (!-e $request_filename) {
rewrite ^/(.*)$ /index.php?q=$1 last;
break;
}

or

if (!-e $request_filename) {
rewrite ^(.+)$ /index.php?q=$1 last;
break;
}

advany · December 31, 2007, 8:14am

ok I’m running 0.6.4. maybe thats why mine didn’t work for you.

HonDev’s regex rewrite doesn’t work for me. I found a few other sites
that list the same or slightly modified rewrite rule. After 10 hours
trying to figure out wtf the problem was (I just installed and started
using nginx today) I realized it had to be the rewrite rule so I
examined it more closely. Below is the rewrite rule that works for me
with

Wordpress 2.3.1
nginx version: nginx/0.5.34

Make sure you clear your cache after changing the rewrite rule.

      if (!-e $request_filename) {
        rewrite ^(.*)$ $1/index.php last;

If anyone wants to see my nginx.conf I can post it here. Also, if the
rewrite rule works for you please reply and let me know. Thanks!
