Bonjour,

smeserver v 10.1
Suite a une coupure d'alimentation mariadb ne fonctionne plus.
J'obtiens cette erreur au lancement de mysql:

Code: [Select]

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
Si je redémarre le service (systemctl restart mariadb)

Code: [Select]

Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xe" for details.

Merci pour votre aide

The authentication failures you have shown in your log are nothing to do with Maria DB.

They are people trying to authenticate against dovecot/mail.

Pour l'instant j'ai installé mariadb105, et en créant un lien symbolique /var/lib/mysql/mysql.sock vers /var/lib/mysql/mariadb105.sock, toutes les commandes mysql utilisent la version 10.5, c'est transparent, seul owncloud installé dans une ibay a dû être reconfiguré.

Tous fonctionne correctement en attendant de trouver une solution pour mysql

[ReetP]

It would help a lot if you stuck to one thing at a time and stopped trying to hack your way around an issue. You are likely to make a bad problem worse.

and creating a symlink /var/lib/mysql/mysql.sock to /var/lib/mysql/mariadb105.sock, all mysql commands use version 10.5

You think this is a suitable solution? Do you know what else your DB might be used for?

Have you taken the time to read about the differences between the database versions and the issues you are likely to face?

See:

https://xyproblem.info/


In the meantime, why doesn't Maria start?

If you don't know about how to debug this then you probably should not be doing what you did above......

Have you checked the maria logs?

Code: [Select]

cat /var/log/mariadb/mariadb.log

What errors does it show?

I really suggest you fix this first before trying to break your server.

If I posted on this forum it is to get help and not criticism because the problem I am having is beyond my skills.

In which case please read the previous link and understand that if you don't know the answers, don't go rushing ahead doing things you do not understand. You will just make it worse and quite possibly harder to fix. If the error was beyond your skills then your attempt at a "fix" was as well.

If you experience errors, just stop, and fix it.

Note that when you do updates/upgrades etc there is an assumption that databases work and are not broken even of they have no data. If they are broken it can prevent other system actions. it is a very dangerous place for your server to be.

My server continues to work with the indicated solution which is the most important.

It is not a solution. It is a workaround.

You obviously did not check the wiki which we spend a lot of time writing and is the first place to look for people who do not understand.
