Bonjour à tous,
J’ai un problème avec la configuration de Mysql-Server.5.5.33.
J’ai suivi le tutoriel d’Alsacréations sur l’installation et la configuration de ce dernier.
J’ai effectué exactement les même modifications que sur le tutoriel mais mysql ne veux plus redémarrer.
[code]nano /etc/mysql/my.cnf
The MySQL database server configuration file.
You can copy this to one of:
- “/etc/mysql/my.cnf” to set global options,
- “~/.my.cnf” to set user-specific options.
One can use all long options that the program supports.
Run program with --help to get a list of available options and with
–print-defaults to see which it would actually understand and use.
For explanations see
http://dev.mysql.com/doc/mysql/en/server-system-variables.html
This will be passed to all mysql clients
It has been reported that passwords should be enclosed with ticks/quotes
escpecially if they contain “#” chars…
Remember to edit /etc/mysql/debian.cnf when changing the socket location.
[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
default-character-set = utf8
Here is entries for some specific programs
The following values assume you have at least 32M ram
This was formally known as [safe_mysqld]. Both versions are currently parsed.
[mysqld_safe]
socket = /var/run/mysqld/mysqld.sock
nice = 0
[mysqld]
* Basic Settings
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
default-character-set = utf8
default-collation = utf8_general_ci
skip-external-locking
Instead of skip-networking the default is now to listen only on
localhost which is more compatible and is not less secure.
bind-address = 127.0.0.1
* Fine Tuning
key_buffer = 32M
max_allowed_packet = 16M
thread_stack = 192K
thread_cache_size = 8
This replaces the startup script and checks MyISAM tables if needed
the first time they are touched
myisam-recover = BACKUP
#max_connections = 100
#table_cache = 64
#thread_concurrency = 10
* Query Cache Configuration
query_cache_limit = 2M
query_cache_size = 32M
* Logging and Replication
Both location gets rotated by the cronjob.
Be aware that this log type is a performance killer.
As of 5.1 you can enable the log at runtime!
#general_log_file = /var/log/mysql/mysql.log
#general_log = 1
Error logging goes to syslog due to /etc/mysql/conf.d/mysqld_safe_syslog.cnf.
Here you can see queries with especially long duration
log_slow_queries = /var/log/mysql/mysql-slow.log
long_query_time = 2
#log-queries-not-using-indexes
The following can be used as easy to replay backup logs or for replication.
note: if you are setting up a replication slave, see README.Debian about
other settings you may need to change.
#server-id = 1
#log_bin = /var/log/mysql/mysql-bin.log
#expire_logs_days = 10
max_binlog_size = 100M
#binlog_do_db = include_database_name
#binlog_ignore_db = include_database_name
* InnoDB
InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
Read the manual for more InnoDB related options. There are many!
* Security Features
Read the manual, too, if you want chroot!
chroot = /var/lib/mysql/
For generating SSL certificates I recommend the OpenSSL GUI “tinyca”.
ssl-ca=/etc/mysql/cacert.pem
ssl-cert=/etc/mysql/server-cert.pem
ssl-key=/etc/mysql/server-key.pem
[mysqldump]
quick
quote-names
max_allowed_packet = 16M
[mysql]
#no-auto-rehash # faster start of mysql but no tab completition
[isamchk]
key_buffer = 16M
* IMPORTANT: Additional settings that can override those from this file!
The files must end with ‘.cnf’, otherwise they’ll be ignored.
!includedir /etc/mysql/conf.d/
language = /usr/share/mysql/french[/code]

Merci beaucoup
