Terminal mysql error 2002

Question

I do my own installation Apache/php/mysql with a php switcher and phpmyadmin.

I often had an 2002 error on phpmyadmin before I fix it changing the host in the pma file 'pma/config.inc.php' from 'localhost' to '127.0.0.1'.

On my terminal, when typing mysql command, it is always returning me :

> mysql 

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

But if I force connecting with the root password, on the local IP adress 127.0.0.1, it works. Note that in Google Chrome, phpmyadmin works on http://127.0.0.1/pma and http://localhost/pma .

Terminal :

> mysql -u root -h 127.0.0.1 -p
Enter password:

In the /tmp folder I have one locked file :

mysql.sock.lock

Apache version :

> apachectl -v
Server version: Apache/2.4.18 (Unix)

PHP version (remember that I have a php switcher), but it doesn't work with other versions also :

> php -v

Thank you for helping me to have a stable configuration, without installing again MAMP or other server configuration software. I want to be able to use mysql command on my terminal without forcing it, and stop seeing this 2002 error.

Ps : sorry for the first post in french

EDIT : Okay , it seems no one know why. However you can make an alias for "mysql -u root -h 127.0.0.1 -p".

Try adding a ~/.my.cnf with

[client]
user=root
password=crazypasswordhere
