Wordpress 4.1 en local, Erreur de connexion à la BDD MySQL [Résolu]

Bonjoir,

Bon, le message d'erreur n'a pas l'air si rare que ça, mais je n'ai pas réussit à trouver la solution sur le forum.

"Erreur lors de la connexion à la base de données" Lorsque je tape dans mon firefox "http://localhost/wordpress/"

J'ai installé mon site wordpress 4.1 en local (dans var/www/html/).
En suivant des tuto,j'ai pu faire fonctionner le Wordpress en local, avec les mises à jour et tout, top quoi. Hier, tout marchait.

Mais woilà que ce satané message me bloque.

Voici mes quelques essais pour résoudre le souci :

mathieu@mathieu-Akoya-P6647:/var/run/mysqld$ mysql -u root -p
Enter password: 
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Je suis sûr du mot de passe, c'est celui qui est dans le fichier wordpress wp-config.php

Ensuite, j'ai vu cette page internet : http://ubuntulesjours.free.fr/?p=382
J'ai donc essayé...

mathieu@mathieu-Akoya-P6647:/var/run/mysqld$ ls -l /var/run/
total 52
drwxr-xr-x 2 mysql      mysql        40 févr.  7 08:32 mysqld
mathieu@mathieu-Akoya-P6647:/var/run/mysqld$ sudo mkdir /var/run/mysqld
mkdir: impossible de créer le répertoire «/var/run/mysqld»: Le fichier existe
mathieu@mathieu-Akoya-P6647:/var/run/mysqld$ sudo chown mysql:mysql mysqld
chown: impossible d'accéder à «mysqld»: Aucun fichier ou dossier de ce type
mathieu@mathieu-Akoya-P6647:/var/run/mysqld$ sudo mysqld_safe
150207 09:38:44 mysqld_safe Can't log to error log and syslog at the same time.  Remove all --log-error configuration options for --syslog to take effect.
150207 09:38:44 mysqld_safe Logging to '/var/log/mysql/error.log'.

150207 09:38:46 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

Mais rien ne s'écrit dans ce dossier.

La commande pour démarrer mysql avec l'utilisateur mysql ne marche pas non plus :

mathieu@mathieu-Akoya-P6647:/var/run/mysqld$ mysql -u mysql -p
Enter password: 
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Voici d'autres commande que j'ai essayé :

mathieu@mathieu-Akoya-P6647:/var/run/mysqld$ sudo /etc/init.d/mysql start
 * Starting MySQL database server mysqld

mathieu@mathieu-Akoya-P6647:~$ rlwrap -a mysql -uroot -p
Enter password: 
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

mathieu@mathieu-Akoya-P6647:~$ sudo service mysql start
[sudo] password for mathieu:

Rien ne change lorsque je mets "bind-address        = 127.0.0.1" en commentaire

Vous avez remarqué, je suis novice et assez largué sur mon souci...

Bon...
Je viens de redémarrer mon ordinateur, ça remarche.
Si quelqu'un comprends quelque chose, qui puisse être utile à d'autres, qu'il n'hésite pas !
Bisou !
