How to redirect domain ?

Hello, i want to redirect domain, from domain a.com to b.com.
I want all request to a.com will change to b.com and let google bot know it.

Ex : a.com => b.com
a.com/1.php => b.com or b.com/1.php


I running with linux/apache

 

You should add to .htaccess file on a.com this code:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www\.)?a\.com
RewriteRule (.*) http://www.b.com/$1 [R=301,L] 

Code (markup):

 

Redirect #301: http://www.webconfs.com/how-to-redirect-a-webpage.php

 

vanyinet's solution is the right one to use.

 

Thank you.

Do i need to create a redirect page in a.com/index.html or a.com/index.php ?

 

No, you don't need to create a redirect page.
