Je ne peux pas démarrer MySQL sur Linux - Erreur mysqld_safe
J'ai trouvé dans de nombreux forums sur le web, mais je n'ai pas trouvé ma solution . Lorsque je lance le service mysql sur le serveur linux ubuntu 12.04, j'ai l'erreur suivante:
root@stroke:/# mysqld_safe &
[1] 5789
root@stroke:/# 131001 10:12:29 mysqld_safe Logging to syslog.
131001 10:12:29 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
131001 10:12:29 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended
J'ai déjà donné l'autorisation au dossier mysql, j'ai aussi essayé de créer un nouveau mot de passe pour la racine mysql. Mais jusqu'à présent, rien n'a fonctionné.
Merci pour l'aide.
Des informations:
root@stroke:/# /etc/init.d/mysql start
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service mysql start
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start mysql
start: Job failed to start
Le fichier /etc/mysql/my.cnf

# The MySQL database server configuration file.

# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.

# 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.

MySQL fonctionne sous son propre utilisateur, donc le démarrer sous root n’est pas une sage décision. Et maintenant, lorsque vous avez déjà essayé, certains de vos fichiers peuvent appartenir à root afin que le service ne puisse pas démarrer.
- Vérifiez que tous les répertoires de la base de données MySQL appartiennent à l’utilisateur
mysql. - Essayez de démarrer le service via upstart:
start mysql - Dans le répertoire avec la base de données MySQL, vérifiez le fichier journal.
Le port 3306 est-il déjà utilisé? Essayer:
netstat -an | grep 3306
Edit: comment démarrez-vous MySQL? Essayer:
/etc/init.d/mysql start
Cette erreur se produit souvent si MySQL ne peut pas fonctionner avec ses propres répertoires.
Dans cette erreur, vous devriez:
- Vérifiez le répertoire des bases de données (souvent -
/var/lib/mysql) - Le répertoire de vérification où mysql stocke le fichier pid (souvent -
/var/run/mysqld).
Ce répertoire devrait avoir un utilisateur et un groupe mysql:mysql (ou autre, si MySQL est exécuté par un autre utilisateur).
Dans votre cas, le répertoire /var/run/mysqld/ n'est pas accessible en écriture. Vous devriez changer l'utilisateur et le groupe pour ce répertoire:
chown mysql:mysql /var/run/mysqld
Vérifier les autorisations de
/var/lib/mysql/var/run/mysqldCes dossiers doivent appartenir à l'utilisateur et au groupe
mysql./tmp/doit être en écriture globale
