Résumé de la discussion
Le problème central est qu'un serveur MySQL ne démarre pas et renvoie l'erreur Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock', même après désinstallation et réinstallation.
Des éléments de réponse indiquent que le service est arrêté et qu'il n'y a pas de processus mysqld actif, ce qui empêche une connexion via le socket.
Plusieurs propositions visent à démarrer manuellement le daemon avec mysqld_safe ou --skip-grant, à vérifier les droits dans /var/lib/mysql/mysql et à examiner les messages de démarrage pour orienter le dépannage.
En cas d'échec persistant, certaines interventions suggèrent aussi d'examiner les permissions du socket et des fichiers liés et d'envisager des vérifications supplémentaires sur /var/run/mysqld et la propriété des fichiers système.
Bonjour
Est-ce que /var/run/mysqld/mysqld.sock existe encore ?
Si mysqld n'est pas lancé, ce ne devrait plus être le cas.
Il est possible que ta machine se soit arrêté brutalement et que le fichier n'ai pas été supprimé.
Passe en root et renomme le, puis essaie de relancer mysql...
Est-ce que ça marche ou pas ?
A plus.
Bon courage.

Posez votre question
est-ce que ton serveur mysql est démarré ??
qu'indique la commande suivante (à taper en root) :
qu'indique la commande suivante (à taper en root) :
/etc/init.d/mysql status
Je pense qu'il n'est pas démarré puisque le démarrage échoue à chaque tentative.
voila le résultat de la commade:
# /etc/init.d/mysql status
MySQL is stopped..
voila le résultat de la commade:
# /etc/init.d/mysql status

# /etc/init.d/mysql start
Starting MySQL database server: mysqld . . . . . . . . . . . . . . failed!
Starting MySQL database server: mysqld . . . . . . . . . . . . . . failed!
Je ne sais pas si c'est le cas. J'ai essayer une fois la desinstallation puis la reinstallation. je ne saurais dire si c'est bien ou pas installé
J'ai effectuer les commandes suivantes:
#dpkg --purge mysql-server-5.0
# aptitude update
#aptitude safe-upgrade
# aptitude install mysql-server-5.0
#dpkg --purge mysql-server-5.0
# aptitude update
#aptitude safe-upgrade
# aptitude install mysql-server-5.0
J'avais exécuté ces commandes pour la désinstallation
# apt-get --purge remove mysql-server
# apt-get --purge remove mysql-cleint
# apt-get --purge remove mysql-common
voila le résultat de tes commandes
# /etc/init.d/mysqld status
bash: /etc/init.d/mysqld: No such file or directory
# /etc/init.d/mysqld start
bash: /etc/init.d/mysqld: No such file or directory
# apt-get --purge remove mysql-server
# apt-get --purge remove mysql-cleint
# apt-get --purge remove mysql-common
voila le résultat de tes commandes
# /etc/init.d/mysqld status
bash: /etc/init.d/mysqld: No such file or directory
# /etc/init.d/mysqld start
bash: /etc/init.d/mysqld: No such file or directory
