How to redirect one route from a domain some where else in apache

  • 772

I have what, from my searching so far, seems to be a slightly different problem with site redirections than the norm. I need to redirect one particular route from one domain to another on a different port.

So far I've tried a simple 301 Redirect and a rewrite to no avail.

The code looks like

<VirtualHost *:80>                                                                                                                      
  ServerName blah.hardsoft.nexus.blah2.blah3.au/phpmyadmin                                                                           
  RewriteEngine on                                                                                                                      
  RedirectMatch "^blah.*nexus.*\/phpmyadmin$" "http://10.1.140.1:8080/phpmyadmin"                                                   
  #RedirectMatch ".*nexus.*" "http://10.1.140.1:8080/phpmyadmin"                                                                         

  #Redirect 301 / http://10.1.140.1:8080/phpmyadmin                                                                                     
  </VirtualHost>                                                                                                                          

<VirtualHost 10.1.140.1:8080>                                                                                                            
  ServerName phpmyadmin                                                                                                                  
  DocumentRoot /var/www-8080                                                                                                             
</VirtualHost>

As you can see I've tried a couple of redirect matches (one very broad) and a 301 redirect, but in all cases what I end up with is it being redirected to

 10.1.140.1/phpmyadmin

without the port being appended (at least I think that's whats happening).

Any idea how I should be doing this? Is it even possible?

mod-rewrite

  1. You can use mod_rewrite for redirection with port number. First, enable mod_rewrite in your server (a2enmod rewrite), then add this to your config:

    RewriteEngine on
RewriteRule "^/phpmyadmin(.*)$" "http://10.1.140.1:8080/phpmyadmin$1" [L,R=301,NE]

    I guess the URL to be redirected starts with "/phpadmin", that's why I used the "^" in the regex. If this is wrong, then change the rule accordingly.

    Flags used:

    [L] - last rule, no further processing takes place
    [R=301] - Redirect permanent
    [NE] - no encoding of special characters

    Then restart your server and test.

    EDIT: Just saw that you had a RewriteEngine on in your config, so mod_rewrite is probably already enabled. Note that you only need mod_alias for a Redirect or RedirectMatch!
