It was developed by MariaDB foundation, and is being led by original developers of MySQL. Working with MariaDB is entirely same as MySQL. After Oracle bought MySQL, it is not free and open source anymore, but MariaDB is still free and open source. Top Websites like Google, Wikipedia, Linkedin, Mozilla and many more migrated to MariaDB. Its features are. From Access connecting to MariaDB's MySQL Database via from Access 2016 -External Data -ODBC Database ( Export selected object to an ODBC Database, such as SQL server ).

Being a fork of a leading open source software system, it is notable for being led by the original developers of MySQL, who forked it due to concerns over its acquisition by Oracle. Contributors are required to share their copyright with the MariaDB Foundation.The intent is also to maintain high compatibility with MySQL, ensuring a “drop-in” replacement capability with library binary equivalency and exact matching with MySQL APIs and commands. It includes the XtraDB storage engine for replacing InnoDB, as well as a new storage engine, Aria, that intends to be both a transactional and non-transactional engine perhaps even included in future versions of MySQL.How to use this image Start a mariadb server instanceStarting a MariaDB instance is simple. $ docker run -name some-mariadb -e MYSQLROOTPASSWORD =my-secret-pw -d mariadb:tag.
Where some-mariadb is the name you want to assign to your container, my-secret-pw is the password to be set for the MySQL root user and tag is the tag specifying the MySQL version you want. See the list above for relevant tags. Connect to MariaDB from the MySQL command line clientThe following command starts another mariadb container instance and runs the mysql command line client against your original mariadb container, allowing you to execute SQL statements against your database instance. # Use root/example as user/password credentials version: ' 3.1' services: db: image: mariadb restart: always environment: MYSQLROOTPASSWORD: example adminer: image: adminer restart: always ports: - 8080:8080Run docker stack deploy -c stack.yml mariadb (or docker-compose -f stack.yml up), wait for it to initialize completely, and visit or (as appropriate). Container shell access and viewing MySQL logsThe docker exec command allows you to run commands inside a Docker container. The following command line will give you a bash shell inside your mariadb container.
$ docker logs some-mariadbUsing a custom MySQL configuration fileThe startup configuration is specified in the file /etc/mysql/my.cnf, and that file in turn includes any files found in the /etc/mysql/conf.d directory that end with.cnf. Settings in files in this directory will augment and/or override settings in /etc/mysql/my.cnf. If you want to use a customized MySQL configuration, you can create your alternative configuration file in a directory on the host machine and then mount that directory location as /etc/mysql/conf.d inside the mariadb container.If /my/custom/config-file.cnf is the path and name of your custom configuration file, you can start your mariadb container like this (note that only the directory path of the custom config file is used in this command).
$ docker run -name some-mariadb -v /my/custom:/etc/mysql/conf.d -e MYSQLROOTPASSWORD =my-secret-pw -d mariadb:tagThis will start a new container some-mariadb where the MariaDB instance uses the combined startup settings from /etc/mysql/my.cnf and /etc/mysql/conf.d/config-file.cnf, with settings from the latter taking precedence. Configuration without a cnf fileMany configuration options can be passed as flags to mysqld.
This will give you the flexibility to customize the container without needing a cnf file. For example, if you want to change the default encoding and collation for all tables to use UTF-8 ( utf8mb4) just run the following. $ docker run -it -rm mariadb:tag -verbose -help Environment VariablesWhen you start the mariadb image, you can adjust the configuration of the MariaDB instance by passing one or more environment variables on the docker run command line.

Do note that none of the variables below will have any effect if you start the container with a data directory that already contains a database: any pre-existing database will always be left untouched on container startup. MYSQLROOTPASSWORDThis variable is mandatory and specifies the password that will be set for the MariaDB root superuser account. In the above example, it was set to my-secret-pw. MYSQLDATABASEThis variable is optional and allows you to specify the name of a database to be created on image startup.
If a user/password was supplied (see below) then that user will be granted superuser access to this database. MYSQLUSER, MYSQLPASSWORDThese variables are optional, used in conjunction to create a new user and to set that user’s password. This user will be granted superuser permissions (see above) for the database specified by the MYSQLDATABASE variable.
Both variables are required for a user to be created.Do note that there is no need to use this mechanism to create the root superuser, that user gets created by default with the password specified by the MYSQLROOTPASSWORD variable. MYSQLALLOWEMPTYPASSWORDThis is an optional variable. Set to yes to allow the container to be started with a blank password for the root user. NOTE: Setting this variable to yes is not recommended unless you really know what you are doing, since this will leave your MariaDB instance completely unprotected, allowing anyone to gain complete superuser access. MYSQLRANDOMROOTPASSWORDThis is an optional variable. Set to yes to generate a random initial password for the root user (using pwgen). The generated root password will be printed to stdout ( GENERATED ROOT PASSWORD.).
Docker SecretsAs an alternative to passing sensitive information via environment variables, FILE may be appended to the previously listed environment variables, causing the initialization script to load the values for those variables from files present in the container. In particular, this can be used to load passwords from Docker secrets stored in /run/secrets/ files. $ docker run -name some-mysql -e MYSQLROOTPASSWORDFILE =/run/secrets/mysql-root -d mariadb:tagCurrently, this is only supported for MYSQLROOTPASSWORD, MYSQLROOTHOST, MYSQLDATABASE, MYSQLUSER, and MYSQLPASSWORD. Initializing a fresh instanceWhen a container is started for the first time, a new database with the specified name will be created and initialized with the provided configuration variables.
Furthermore, it will execute files with extensions.sh,.sql and.sql.gz that are found in /docker-entrypoint-initdb.d. Files will be executed in alphabetical order. You can easily populate your mariadb services by and provide with contributed data. SQL files will be imported by default to the database specified by the MYSQLDATABASE variable.
Caveats Where to Store DataImportant note: There are several ways to store data used by applications that run in Docker containers. We encourage users of the mariadb images to familiarize themselves with the options available, including:.
Let Docker manage the storage of your database data. This is the default and is easy and fairly transparent to the user.
The downside is that the files may be hard to locate for tools and applications that run directly on the host system, i.e. Outside containers. Create a data directory on the host system (outside the container). This places the database files in a known location on the host system, and makes it easy for tools and applications on the host system to access the files. The downside is that the user needs to make sure that the directory exists, and that e.g.
Directory permissions and other security mechanisms on the host system are set up correctly.The Docker documentation is a good starting point for understanding the different storage options and variations, and there are multiple blogs and forum postings that discuss and give advice in this area. We will simply show the basic procedure here for the latter option above:. Create a data directory on a suitable volume on your host system, e.g. /my/own/datadir.Start your mariadb container like this. $ docker run -name some-mariadb -v /my/own/datadir:/var/lib/mysql -e MYSQLROOTPASSWORD =my-secret-pw -d mariadb:tagThe -v /my/own/datadir:/var/lib/mysql part of the command mounts the /my/own/datadir directory from the underlying host system as /var/lib/mysql inside the container, where MySQL by default will write its data files. No connections until MySQL init completesIf there is no database initialized when the container starts, then a default database will be created. While this is the expected behavior, this means that it will not accept incoming connections until such initialization completes.
This may cause issues when using automation tools, such as docker-compose, which start several containers simultaneously. Usage against an existing databaseIf you start your mariadb container instance with a data directory that already contains a database (specifically, a mysql subdirectory), the $MYSQLROOTPASSWORD variable should be omitted from the run command line; it will in any case be ignored, and the pre-existing database will not be changed in any way. Creating database dumpsMost of the normal tools will work, although their usage might be a little convoluted in some cases to ensure they have access to the mysqld server. A simple way to ensure this is to use docker exec and run the tool from the same container, similar to the following. $ docker exec -i some-mariadb sh -c 'exec mysql -uroot -p'$MYSQLROOTPASSWORD'.
