How to redirect/rewrite all /wp-login requests

3 comments

1. To answer you question as a apache URL layout configuration via mod_rewrite (the apache module that handles URL rewriting), this could be helpful:

   RewriteRule ^admin/(.*)$ /wp-admin/$1 [QSA,L]
   

   (untested configuration directive, check the docs in case this does errors)

   This will basically translate any request to /admin/… into /wp-admin/… .

   If that’s the only thing you would like to know, I must admit that this is slightly off-topic for worpdress@se as this is acutally a question how to configure the apache webserver. A better place might be serverfault.

   ---

   Keep in mind that this only rewrites the URLs that get requested. WordPress would know nothing about this and it does still output links to /wp-admin/ on the admin then. There is a hook for any admin URL that you might want to rewrite then as well:

   return apply_filters('admin_url', $url, $path, $blog_id);
   

   You would need to replace the domain/wp-admin/ part with domain/admin/ with a filter on your own.

2. hakre…. Great answer… now with the latest version of wordpress having a separate network admin I used your solution and added in the part to properly rewrite the “Network Admin” links in the same way…

3. In addition to the previous solutions. I found the missing css and script files.

   the fix is

   RewriteEngine On
   RewriteBase /
   RewriteRule ^index.php$ - [L]
   
   # uploaded files
   RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]
   
   # add a trailing slash to /wp-admin
   RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]
   
   # Fix using the previous answer. 
   RewriteRule ^admin/(.*)$ wp-admin/$1 [QSA,L] 
   
   RewriteCond %{REQUEST_FILENAME} -f [OR]
   RewriteCond %{REQUEST_FILENAME} -d
   RewriteRule ^ - [L]
   RewriteRule  ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]
   
   #Fix to load css js image files for multi site admin urls. 
   #old code RewriteRule  ^[_0-9a-zA-Z-]+/(.*.php)$ $1 [L]
   RewriteRule  ^[_0-9a-zA-Z-]+/(.*.(php|css|js|png|jpg|gif))$ $1 [L]
   
   RewriteRule . index.php [L]
