How to redirect/rewrite all /wp-login requests

Question

Is there any simple way to have wordpress, php or apache rewrite all urls which involve /wp-admin to /admin?

I have added this entry to my .htaccess file:

RewriteRule ^admin /wp-login.php [L]

However although domain.com/admin will correctly show the login page all pages after you login show the URL as /wp-admin which I want to always show /admin.

Any thoughts on this?

Answer 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.

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...

Answer 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]
