Server mysql

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.

Une idée reçue est souvent une idée morte.

merci pour ta réponse,

/var/run/mysqld/mysqld.sock n'existe plus.

voici le contenu du fichier my.cnf.

ça fait plusieurs semaines que j'essaye de ressoudre ce problème. aidez moi s'il vous plait

# You can copy this to one of:

# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.

ya personne pour m'aider? je suis perdu, je sais plus quoi faire. HELP PLEASE

est-ce que ton serveur mysql est démarré ??

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..

peux-tu copier-coller ici le résultat de la commande suivante :

/etc/init.d/mysql start

merci.

# /etc/init.d/mysql start
Starting MySQL database server: mysqld . . . . . . . . . . . . . . failed!

est-ce que mysql-server est bien installé ?

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

peux-tu afficher le résultat de cette commande :

ps aux | grep mysql

# ps aux | grep mysql
root 31926 0.0 0.1 3116 724 pts/0 S+ 14:10 0:00 grep mysql

ok ! peux-tu préciser le nom du/des paquet(s) exact(s) mysql que tu as installé ?

J'ai effectuer les commandes suivantes:

#dpkg --purge mysql-server-5.0
# aptitude update
#aptitude safe-upgrade
# aptitude install mysql-server-5.0

au pifomètre, on essaie ceci :

/etc/init.d/mysqld status

/etc/init.d/mysqld start

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

ok ! réinstalle aussi mysql-client !

J'ai fait l'install avec la commande
# aptitude install mysql-client

mais mysql ne démarre toujours pas

ok ! installe aussi mysql-common !

et ensuite démarre mysql comme ceci :

/etc/init.d/mysql start
