[RESOLU] mariadb.service: Failed with result 'exit-code'

TryphonCosinus · Le 05/01/2021, à 21:11

Bonjour et bonne année!

Voilà plusieurs jours que je cherche à installer et démarrer MariaDB. Ma config :

Ubuntu Server 20.04.1 sur partition de 100 GB (83 GB libre) et fraichement installé
Intel® Core™2 Quad CPU @ 2.40GHz × 4
RAM 8 GB
AMD Cayman graphic card

Tout fonctionne sauf MariaDB. La bible que je lis: https://doc.ubuntu-fr.org/mysql#reinstallation_complete
Mes devoirs :

sudo killall mysqld
sudo systemctl disable mysql.service
sudo rm -rf /lib/systemd/system/mysql.service
sudo rm -rf /usr/lib/systemd/system/mysql.service
sudo rm -rf /etc/systemd/system/multi-user.target.wants/mysql.service
sudo rm -rf /var/lib/systemd/deb-systemd-helper-enabled/multi-user.target.wants/mysql.service
sudo rm -rf /var/cache/apt/archives/mysql-server-*.deb

sudo apt-get install -f
sudo dpkg --configure -a
sudo apt autoremove --purge ~n^mysql-server ~n^mariadb-server
sudo apt autoremove
sudo rm -rf /etc/mysql /var/lib/mysql
sudo mkdir -p /etc/mysql/conf.d
sudo apt clean
sudo apt update && sudo apt upgrade
sudo apt install mariadb-server

MariaDB ne démarre pas. La procédure https://doc.ubuntu-fr.org/mysql#reinstallation_complete est insiffisante, incomplète ou non à jour.
Que faut-il faire pour que MariaDB démarre?

Merci!

La doc est à jour. Par contre pas mal de commandes utilisées ne figurent pas dans la doc.

Je rappelle que journalctl -xe ne sert à rien s'il n'est pas exécuté immédiatement après une erreur (lire man journalctl). Pour voir le journal d'un service systemd il faut faire :

journalctl --no-pager -u mysql

Sinon on voit quand même des avertissements et une erreur bloquante grâce à la dernière commande.
Ces erreurs sont dues à des options de configuration invalides. Donc soit tu as modifié (ou conservé) la configuration locale sous /etc/mysql, soit tu as un autre fichier de configuration erroné ailleurs : /etc/my.cnf, /var/lib/mysql/my.cnf, /root/.my.cf, $HOME/.my.cnf, etc.

Tu peux déjà chercher dans /etc:

sudo rgrep early-plugin-load /etc

Bonjour Bruno,

Bravo! il y avait bien un fichier /etc/my.cnf qui contenait la variable early-plugin-load. Je l'ai supprimé et j'ai enchainé sur :

sudo mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
sudo systemctl start mariadb

et MariaDB a démarré.

Et non, je n'avais rien fait d'intentionnel pour écrire un fichier /etc/my.cnf. Mais contrairement aux indications du fichier /etc/mysql/my.cnf

The MariaDB/MySQL tools read configuration files in the following order:
1. "/etc/mysql/mariadb.cnf" to set global defaults,
2. "/etc/mysql/conf.d/*.cnf" to set global options.
3. "/etc/mysql/mariadb.conf.d/*.cnf" to set MariaDB-only options.
4. "~/.my.cnf" to set user-specific options.

If the same option is defined multiple times, the last one will apply.

d'autres emplacements de my.cnf prévallent pour configurer MariaDB. Il faut donc les supprimer aussi pour réinstaller MariaDB.

Je te remercie pour ton intuition à mettre le doigt rapidement sur mon problème.
