WP CLI Can’t connect to local MySQL server through socket

Why is the mysql socket path not downloaded from php.ini?

$ wp db reset
error: ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)

wp-config.php
define('DB_HOST', 'localhost');

php.ini:
mysqli.default_socket: /var/run/mysql/mysql.sock

/etc/my.cnf
socket                         = /var/run/mysql/mysql.sock

works only if I type “–socket=/var/run/mysql/mysql.sock”

can I add to the global configuration of WP CLI socket?
