Hello all
Pouvez vous m'aider?
Je ne comprends pas pourquoi mysql s'est arrêté d'un coup sans qu'on ne touche à rien et refuse de redémarrer.
Merci de votre aide.
voici le contenu du fichier de log de mysql
#--------------mysql.err----------------------------
InnoDB: End of page dump
170609 18:10:10 InnoDB: Page checksum 918991256, prior-to-4.0.14-form checksum 1886869800
InnoDB: stored checksum 918991256, prior-to-4.0.14-form stored checksum 3700301661
InnoDB: Page lsn 2 835419976, low 4 bytes of lsn at page end 835419739
InnoDB: Page number (if stored to page already) 5,
InnoDB: space id (if created with >= MySQL-4.1.1 and stored already) 0
InnoDB: Page may be a transaction system page
InnoDB: Database page corruption on disk or a failed
InnoDB: file read of page 5.
InnoDB: You may have to recover from a backup.
InnoDB: It is also possible that your operating
InnoDB: system has corrupted its own file cache
InnoDB: and rebooting your computer removes the
InnoDB: error.
InnoDB: If the corrupt page is an index page
InnoDB: you can also try to fix the corruption
InnoDB: by dumping, dropping, and reimporting
InnoDB: the corrupt table. You can use CHECK
InnoDB: TABLE to scan your table for corruption.
InnoDB: See also http://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html
InnoDB: about forcing recovery.
InnoDB: Ending processing because of a corrupt database page.
170609 18:10:10 InnoDB: Assertion failure in thread 140247083841344 in file buf0buf.c line 3623
InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to http://bugs.mysql.com.
InnoDB: If you get repeated assertion failures or crashes, even
InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to
InnoDB: http://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html

16:10:10 UTC - mysqld got signal 6 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 346701 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x0

where mysqld died. If you see no messages after this, something went

Tu devrais utiliser la balise code surtout quand c'est long ;) (la coloration syntaxique ne fonctionne qu'avec les langages de programmation par contre).
Quand tu postes un nouveau message cette balise est décrite en bas (sur pc, j'ai pas checké sur mobile)
exemple
```ruby

Tes logs ne montrent pas pourquoi MySQL s'est arrêté, mais la DB est corrompue, soit MySQL s'est crashé, soit il a été killé (par l'OOM Killer par exemple). Soit tu as un backup et tu récupères tes données comme ça avec une réinstallation de MySQL. Soit tu tente une récupération avec innodb force recover .

En effet InnoDB a détecté une corruption (checksum incohérent). Tu peux suivre les instructions mentionnées sur https://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html pour dumper la table et la réimporter, ou restaurer depuis une sauvegarde.

D'expérience, c'est beaucoup mieux plus facile si on peut repartir depuis un backup. Parce que le recovery ne marche pas tout le temps (ou seulement sur certaines tables).

Je confirme. J'ai mentionné l'option de repartir depuis une sauvegarde en dernier, mais c'est la meilleure. De plus il risque de manquer des données même si le dump en force-recovery fonctionne. Avec un peu de chance la corruption est sur un index, mais c'est pas tous les jours qu'on a un ticket gagnant à la loterie :-)
