Nginx redirect all contents of a subdirectory to another subdirectory

Question

Let say that I have a url like this:

http://www.example.com/admin/admin.php?fail=1

how can I rewrite the url to be

http://www.example.com/another/subdirectory/admin.php?fail=1

Thank you

Update: this is what I've tried so far, but it will not redirect admin.php?fail=1

location /admin/ {
    rewrite ^/admin/(.*)$ 
    /another/subdirectory/$1 redirect;
}

Answer 1

I rather use return 301 for redirections and use rewrite only if I want to display something like a nice url.

Please try the following

location  ~ ^/admin/(.*) {
    return 301  /another/subdirectory/$1 ;
}
