# --------------- Uncomment the lines below and put into file:  my.cfg  -----------------------------------------------

##
## 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
#
## 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
#skip-external-locking
#transaction-isolation = READ-UNCOMMITTED
##
## Instead of skip-networking the default is now to listen only on
## localhost which is more compatible and is not less secure.
#bind-address		= 0.0.0.0
##
## * Fine Tuning
##
#key_buffer		= 16M
#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	= 1M
#query_cache_size        = 16M
##
## * 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.
