How do I redirect example.com to example.com/subdirectory?

I’m trying to redirect example.com (and example.com/, www.example.com and www.example.com/) to example.com/sub开发者_如何学Cdirectory. I could do this easily using HTML but from what I read, it’s better to make a 301 redirect using Apache.

How can I do this using Apache?

If you want 301 redirect:

RedirectMatch 301 ^/$ /subdirectory/

You should use a .htaccess file using the RewriteRule keyword. See Apache docs for more info on how to do this.

Options +FollowSymLinks
RewriteEngine on
RewriteRule (.*) http://www.newdomain.com/$1 [R=301,L]

Note* This .htaccess method of redirection works ONLY on Linux servers having the Apache Mod-Rewrite moduled enabled.

Example usage would be

RewriteRule ^/$ http://somewhere.com/directory [R=301,L]
