Redirect only WordPress homepage with a 301 redirect

Question

I have a blog, lets say example.com and another blog installed in example.com/np which is not multisite but a different WordPress installation.

Since you're in the context of WordPress, you can utilize its redirect functionality.

Like this ( in functions.php ):

function redirect_homepage() {
    if( ! is_home() && ! is_front_page() )
        return;

    wp_redirect( 'http://redirect-here.com', 301 );
    exit;
}

add_action( 'template_redirect', 'redirect_homepage' );
