You can check that:

function auto_login_new_user( $user_id ) {
    wp_set_current_user($user_id);
    wp_set_auth_cookie($user_id);
    wp_redirect( home_url() ); // You can change home_url() to the specific URL,such as "wp_redirect( 'http://www.wpcoke.com' )";
    exit();
}
add_action( 'user_register', 'auto_login_new_user' );
