Security Sysadmin WP-CLI not pleased with moving wp-config.php to other location

To improve security even a step futher I wanted to change the location of the wp-config.php out of the public folder.

---

My wp-config.php is this:

Code (Text):

<?php

/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
    define('ABSPATH', dirname(__FILE__) . '/');

/** Location of your WordPress configuration. */
require_once(ABSPATH . '../private/some-config.php');

But running the wp_updater gives me an error on PHP

Code (Text):

[11:38][root@server8]# sh ./wp_updater_domain.com.sh
/home/nginx/domains/domain.com/public
update wp-cli

I was reading the same issue here but that did not give a clue to resolve it.
How to use wp-cli with a non-standard wp-config.php location

 

So adding the below to the some-config gave me another error.

Code (Text):

<?php

/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
    define('ABSPATH', dirname(__FILE__) . '/');

/** Location of your WordPress configuration. */
require_once(ABSPATH . '../private/some-config.php');

/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-config.php');

Guess I'm not the same PHP consumer/eater as you, simply don't get what's wrong.

Code (Text):

PHP Fatal error:  Cannot redeclare wp_get_server_protocol() (previously declared in /home/nginx/domains/domain.com/public/wp-includes/load.php:16) in /home/nginx/domains/domain.com/public/wp-includes/load.php on line 21

I looked here and my setup is this

Code (Text):

├── private
│   └── some-conf.php   <----|
├── public                       |
│   ├── index.php                |
│   └──  wp-config.php      -----|  (required file)
