comment réinstaller mysql?

Une mise à jour du logiciel a été interrompue, entre autres choses, mysql et moi n’avons pas encore été en mesure de le récupérer.

Cause suspectée: le disque de démarrage était presque plein. la mise à niveau a rempli le disque avant de terminer et a donc tout laissé dans le pétrin. J'ai donné plus de disque au système et déplacé/var vers sa propre partition. J'essaie toujours en vain de faire revivre mysql.

Ci-dessous, ce que j’ai essayé jusqu’à présent (tout en tant que root). Tout d'abord, mysql ne démarre pas (443). Les tentatives de réparation (444, 445) échouent. Les tentatives pour supprimer mysql et (?) Apparmor échouent (446, 7, 8). Une tentative plus énergique de supprimer mysql semble réussir (449) et les erreurs précédentes ne sont plus observées (450, 1, 2). Mysql ne peut pas être reconfiguré car il n'est plus là (453) mais si vous tentez de le réinstaller, les anciens messages d'erreur sont restitués et nous revenons à la case départ (454).

J'ai aussi vérifié cette question (même si dans mon cas, cela ne s'est pas cassé à cause d'une mise à jour vers 12.04: il travaillait déjà sur 12.10) Correction du paquetage myslq-server cassé après la mise à jour vers 12.04 et j'ai essayé les suggestions dans (458, 461, 462) en vain.

Que dois-je faire d'autre?

Tout d'abord, supprimez MySQL:

Sudo apt purge mysql-server mysql-client mysql-common
Sudo apt autoremove
Sudo mv -iv /var/lib/mysql /var/tmp/mysql-backup
Sudo rm -rf /var/lib/mysql*

Puis réinstallez:

Sudo apt update
Sudo apt install mysql-server
Sudo mysql_install_db
Sudo /usr/bin/mysql_secure_installation

Dans Ubuntu 16.04, le moyen de résoudre ce problème dans mon cas était (sauvegardez d'abord les bases de données, les bases de données seront perdues):

Sudo apt remove --purge mysql-server mysql-client mysql-common
Sudo apt autoremove
Sudo mv -iv /var/lib/mysql /var/tmp/mysql-backup
Sudo rm -rf /var/lib/mysql*
Sudo apt install mysql-server

(D'une certaine manière, mes appels précédents à apt purge mysql-server n'ont pas semblé aboutir. Je pensais que apt purge foo était équivalent à apt remove --purge foo...)

J'obtenais exactement les mêmes erreurs et j'ai essayé la plupart des étapes que vous avez faites, avec les mêmes résultats. Ce qui suit a finalement fonctionné pour moi.

apt-get purge mysql-server mysql-client mysql-common mysql-client-5.5 mysql-server-5.5

Après cela, mysql s'est installé normalement.

Je ne suis pas sûr de ce qui a été le cas pour moi, mais les autres solutions n'ont pas fonctionné et ont continué à donner une erreur. J'ai essayé ce apt-get purge mysql-*, puis autoremove et autoclean. Après cette installation était bien.

**

Assurez-vous de sauvegarder vos bases de données, la commande ci-dessus peut également les supprimer.

Pour la version MySQL 5.7, j'ai supprimé MySQL comme décrit précédemment:

Sudo apt purge mysql-server mysql-client mysql-common
Sudo apt autoremove
Sudo rm -rf /var/lib/mysql*

Et installé avec l'aide:

Sudo apt-get update
Sudo apt-get install mysql-server
mysql_secure_installation

Pour tester si tout fonctionne:

systemctl status mysql.service

source

Si vous courez juste

Sudo apt-get update
Sudo apt-get install mysql-server

cela va mettre à jour mysql et cela corrige le problème que j'avais après la mise à jour à 16.04 lts.

Ou simplement courir

Sudo apt-get install lamp-server^

mettre à jour tous les packages du serveur.
