Short Description
MariaDB based on Debian image
Full Description

Run with

docker run -d -p 3306:3306 --name mariadb -v $(pwd)/configuration/my.cnf:/etc/mysql/my.cnf -v $(pwd)/data:/var/lib/mysql mariadb:base

you need a local configuration folder with the my.cnf

my.cnf example,


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

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.

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.

socket = /var/run/mysqld/mysqld.sock
nice = 0


* Basic Settings

user = mysql
pid-file = /var/run/mysqld/
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql

Instead of skip-networking the default is now to listen only on

localhost which is more compatible and is not less secure.

#bind-address =

* Fine Tuning

key_buffer = 16M
max_allowed_packet = 256M
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 log - should be very few entries.

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

Here you can see queries with especially long duration

#slow_query_log_file = /var/log/mysql/mysql-slow.log

#slow_query_log = 1

#long_query_time = 2


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".





#custom settings

max_allowed_packet = 256M


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

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/
