Donc voilà le truc, hier j'ai installé Mysql, Phpmyadmin, php5 et tout ce qui va avec.
Je commence mon site (en local) et tout marche.
Aujourd'hui impossible d'y accéder.

Impossible aussi d'accéder à phpmyadmin :

1. 2002 Connexion au serveur MySQL non permise

La connexion au controluser tel que défini dans votre configuration a échoué.

Et pareil pour Mysql administrator :
Could not connect to host 'localhost'.
MySQL Error Nr. 2002
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Quelqu'un a déjà eu ce problème ? Je n'ai pourtant touché à rien d'autre depuis hier.

est ce que les daemons sont correctement demarres ?

Je sais pas si je me trompe ou pas mais en faisant "service mysql start" j'ai :
start: Job is already running: mysql

Donc logiquement il est en route, et pourtant rien ne marche.

essai "service mysql reload" ou restart

après as-tu touché un réglage ?

service mysql reload
reload: Inactif

service mysql restart
mysql start/running

Mais en essayant de me connecter à phpmyadmin ou à mysql ça ne marche toujours pas et j'ai toujours les memes erreurs.

Minute papillon...

Relances mysql et fait un

1. tail -n 20 /var/log/syslog

et donne le résultat

Voilà ce que j'ai :

$ mysql -u"ton login" -p"ton mot de passe"
ça donne quoi ?

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

tu peux me donner le contenu de /etc/mysql/my.cnf stp ?

Le voilà :

#

1. The MySQL database server configuration file.

#

1. You can copy this to one of:
2. - "/etc/mysql/my.cnf" to set global options,
3. - "~/.my.cnf" to set user-specific options.
5. One can use all long options that the program supports.
6. Run program with --help to get a list of available options and with
7. --print-defaults to see which it would actually understand and use.

#

1. For explanations see
2. http://dev.mysql.com/doc/mysql/en/server-system-variables.html

1. This will be passed to all mysql clients
2. It has been reported that passwords should be enclosed with ticks/quotes
3. escpecially if they contain "#" chars...
4. Remember to edit /etc/mysql/debian.cnf when changing the socket location.

[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock

1. Here is entries for some specific programs
2. The following values assume you have at least 32M ram

1. This was formally known as [safe_mysqld]. Both versions are currently parsed.

[mysqld_safe]
socket = /var/run/mysqld/mysqld.sock
nice = 0

[mysqld]

#

1. • Basic Settings

#

#

1. • IMPORTANT
2. If you make changes to these settings and your system uses apparmor, you may
3. also need to also adjust /etc/apparmor.d/usr.sbin.mysqld.

#

user = mysql
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
skip-external-locking

#

1. Instead of skip-networking the default is now to listen only on
2. localhost which is more compatible and is not less secure.

bind-address = 127.0.0.1

#

1. • Fine Tuning

#

key_buffer = 16M
max_allowed_packet = 16M
thread_stack = 192K
thread_cache_size = 8

1. This replaces the startup script and checks MyISAM tables if needed
2. the first time they are touched

myisam-recover = BACKUP

1. max_connections = 100
2. table_cache = 64
3. thread_concurrency = 10

#

1. • Query Cache Configuration

#

query_cache_limit = 1M
query_cache_size = 16M

#

1. • Logging and Replication

#

1. Both location gets rotated by the cronjob.
2. Be aware that this log type is a performance killer.
3. As of 5.1 you can enable the log at runtime!
4. general_log_file = /var/log/mysql/mysql.log
5. general_log = 1

log_error = /var/log/mysql/error.log

1. Here you can see queries with especially long duration
2. log_slow_queries = /var/log/mysql/mysql-slow.log
3. long_query_time = 2
4. log-queries-not-using-indexes

#

1. The following can be used as easy to replay backup logs or for replication.
2. note: if you are setting up a replication slave, see README.Debian about
3. other settings you may need to change.
4. server-id = 1
5. log_bin = /var/log/mysql/mysql-bin.log

expire_logs_days = 10
max_binlog_size = 100M

1. binlog_do_db = include_database_name
2. binlog_ignore_db = include_database_name

#

1. • InnoDB

#

1. InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
2. Read the manual for more InnoDB related options. There are many!

#

1. • Security Features

#

1. Read the manual, too, if you want chroot!
2. chroot = /var/lib/mysql/

#

1. For generating SSL certificates I recommend the OpenSSL GUI "tinyca".

#

1. ssl-ca=/etc/mysql/cacert.pem
2. ssl-cert=/etc/mysql/server-cert.pem
3. ssl-key=/etc/mysql/server-key.pem

[mysqldump]
quick
quote-names
max_allowed_packet = 16M

[mysql]

1. no-auto-rehash # faster start of mysql but no tab completition

[isamchk]
key_buffer = 16M

#

1. • IMPORTANT: Additional settings that can override those from this file!
2. The files must end with '.cnf', otherwise they'll be ignored.

#

!includedir /etc/mysql/conf.d/

J'ai finalement fait un
"sudo dpkg-reconfigure mysql-server-5.1" j'ai pu redéfinir le mdp et ça remarche.
Par contre je comprends pas pourquoi le mdp aurait changé d'un jour à l'autre alors que j'ai rien touché.
