Hello,

as-tu toujours le problème ? Si oui, je t'invite à m'appeler directement (le numéro est sur mon site).

SI tu préfères faire ça tout seul, le problème est à priori ici :

Jul 11 03:17:44 ns358376 mysqld: InnoDB: Error: log file ./ib_logfile0 is of dif ferent size 0 67108864 bytes
Jul 11 03:17:44 ns358376 mysqld: InnoDB: than specified in the .cnf file 0 52428 80 bytes!

Tu as changé la taille du paramètre innodb_log_file_size, ce qui implique une petite procédure précise.

Anyome · 12 Juillet 2015

Merci Bool t'es un sauveur !
Sinon, est ce que tu aurais une idée pour mon autre problème

J'ai Mysql qui utilise tous mon CPU (80% - 79%) desfois

Bool · 12 Juillet 2015

de rien !

Pour le second problème, il faudrait commencer par activer les logs slow_queries de MySQL, afin de voir de quoi il retourne.

# Whether slow queries should be logged
slow_query_log = 1

# The name of the slow query log file.
slow_query_log_file = /var/log/mysql/mysql-slow.log

# If a query takes longer than this many seconds, the server increments the
# Slow_queries status variable. If the slow query log is enabled, the query is
# logged to the slow query log file.
long_query_time = 0.1

lance les scripts mysqltuner
et

Anyome · 12 Juillet 2015

Je trouve ou le fichier de configuration pour activer le slow query mode?

Bool · 12 Juillet 2015

Vu que tu es sous Debian, le mieux c'est de créer un fichier spécifique dans /etc/mysql/conf.d/ qut tu appelleras par exemple "anyome.cnf" (l'extension est importante).
Et la première ligne du fichier doit contenir : [mysqld]

Ainsi tu feras plus facilement la différence entre les trucs par défaut de MySQL/Debian, situés dans le my.cnf, et tes modifs persos.
