Avoir des problèmes avec MySql

J'ai installé le serveur sans tête Ubuntu 14.04 hier. La seule chose que j'ai installée à ce moment-là était ssh. J'ai mis à jour le serveur, puis installé Plesk avec son script d'installation automatisé.

Ceci est un serveur virtuel fonctionnant sur hyper-v. J'ai 12 cœurs, 16 Go de RAM, et un disque dur de 500 Go attribué.

J'ai accédé au site Web sans problème. Je n'ai pas encore de certificat SSL valide car je ne m'étais pas rendu jusque-là. J'ai ensuite installé la licence pour Plesk. J'ai fouillé un peu pour voir comment cela fonctionnait, puis je suis allé me ​​coucher. J'ai commencé ce matin là-dessus et le site ne serait pas affiché. Je n'arrivais pas à obtenir une connexion lorsque j'essayais d'accéder au site. Je lis autour et il a dit d'essayer ceci pour le réparer :

cd /var 
Sudo mkdir mysql
Sudo chmod 755 mysql
cd mysql
Sudo ln -s /tmp/mysql.sock mysql.sock

Cela m'a permis d'accéder au site. Lorsque j'essaie de faire quelque chose sur le site, je reçois ceci:

ERREUR: PleskDBException: Impossible de se connecter à la base de données: mysql_connect (): Aucun fichier ou répertoire de ce type /var/run/mysqld/mysqld.sock (Code d'erreur: 2002). Veuillez vérifier que le serveur de base de données est démarré et accessible. (Abstract.php: 69)

J'ai vérifié les journaux dans /var/log/mysql/error.log, le mysql.error avait zéro octet:

Je n'ai apporté aucun changement autre que ce que j'ai indiqué ci-dessus. Quelqu'un a des suggestions où chercher ou quoi faire?

Un peu plus d'infos:

Recherche dans les fichiers mysqld.sock et mysql.sock:

> Sudo find . -name mysqld.sock
> Sudo find . -name mysql.sock
./var/mysql/mysql.sock
> Sudo find . -name my.cnf
./etc/mysql/my.cnf

Vérifié mon.cnf et il avait ceci:

#
# * Basic Settings
#
user            = mysql
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
port            = 3306
basedir         = /usr
datadir         = /var/lib/mysql
tmpdir          = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking

Ce répertoire est vide:/var/run/mysqld

Je ne connais pas très bien la configuration de MySql, mais j’ai pensé partager cela ...

14.04servermysql

J'ai vécu cela aujourd'hui. Je viens d'arrêter mysql et de le redémarrer:

# service mysql stop
mysql stop/waiting
# service mysql start
mysql start/running, process 4042

Je ne suis pas sûr d'une solution appropriée pour cela.

Modifier:

Après avoir suivi /var/log/mysql/error.log, j'ai déterminé qu'il y avait plusieurs versions de mysql essayant de s'exécuter. J'ai enlevé /etc/init.d/mysql et je n'ai pas reçu cette erreur au prochain redémarrage.

Edit 2:

BACKUP /etc/init.d/mysql FIRST

# This will maintian all file ownership and permissions
# and back this up in your home directory:
cp -ar /etc/init.d/mysql "$HOME"
