Deploy MariaDB Community Server
These instructions detail the deployment of MariaDB Community Server 10.5 in a Single Standalone Server configuration on a range of supported Operating Systems.
These instructions detail how to deploy a single-node row database, which is suited for a transactional or OLTP workload that does not require high availability (HA). This deployment type is generally for non-production use cases, such as for development and testing.
These instructions detail the deployment of the following MariaDB Community Server components:
MariaDB Corporation provides package repositories for YUM (RHEL, CentOS), APT (Debian, Ubuntu), and ZYpp (SLES).
Configure the YUM package repository.
Prefix the version with mariadb- and pass the version string to the --mariadb-server-version flag to . The following directions reference 11.4.
To configure YUM package repositories:
Checksums of the various releases of the mariadb_repo_setup script can be found in the
Configure the APT package repository.
Prefix the version with mariadb- and pass the version string to the --mariadb-server-version flag to . The following directions reference 11.4.

MariaDB Community Server can be configured in the following ways:
and can be set in a configuration file (such as /etc/my.cnf). MariaDB Community Server must be restarted to apply changes made to the configuration file.
and can be set on the command-line.
If a system variable supports dynamic changes, then it can be set on-the-fly using the statement.
MariaDB's packages include several bundled configuration files. It is also possible to create custom configuration files.
On RHEL, CentOS, and SLES, MariaDB's packages bundle the following configuration files:
/etc/my.cnf
/etc/my.cnf.d/client.cnf
/etc/my.cnf.d/mysql-clients.cnf
And on RHEL, CentOS, and SLES, custom configuration files from the following directories are read by default:
/etc/my.cnf.d/
On Debian and Ubuntu, MariaDB's packages bundle the following configuration files:
/etc/mysql/my.cnf
/etc/mysql/mariadb.cnf
/etc/mysql/mariadb.conf.d/50-client.cnf
And on Debian and Ubuntu, custom configuration files from the following directories are read by default:
/etc/mysql/conf.d/
/etc/mysql/mariadb.conf.d/
Determine which and you need to configure.
Useful system variables and options for MariaDB Community Server include:
MariaDB Community Server includes configuration to start, stop, restart, enable/disable on boot, and check the status of the Server using the operating system default process management system.
For distributions that use systemd (most supported OSes), you can manage the Server process using the systemctl command:
When MariaDB Community Server is up and running on your system, you should test that it is working and there weren't any issues during startup.
Connect to the Server using using the root@localhost user account:
${checksum} in the example above with the latest checksum.Install MariaDB Community Server and package dependencies:
Configure MariaDB.
Installation only loads MariaDB Community Server to the system. MariaDB Community Server requires configuration before the database server is ready for use.

/etc/my.cnf.d/server.cnf/etc/mysql/mariadb.conf.d/50-mysql-clients.cnf/etc/mysql/mariadb.conf.d/50-mysqld_safe.cnf
/etc/mysql/mariadb.conf.d/50-server.cnf
/etc/mysql/mariadb.conf.d/60-galera.cnf
Sets the maximum number of simultaneous connections MariaDB Community Server allows.
Sets how MariaDB Community Server handles threads for client connections.
Sets the file name for the error log.
Sets the amount of memory InnoDB reserves for the Buffer Pool.
Sets the size for each Redo Log file and sets the number of Redo Log files used by InnoDB.
Sets the maximum number of I/O operations per second that InnoDB can use.
Choose a configuration file in which to configure your system variables and options.
It is not recommended to make custom changes to one of the bundled configuration files. Instead, it is recommended to create a custom configuration file in one of the included directories. Configuration files in included directories are read in alphabetical order. If you want your custom configuration file to override the bundled configuration files, then it is a good idea to prefix the custom configuration file's name with a string that will be sorted last, such as z-.
On RHEL, CentOS, and SLES, a good custom configuration file would be: /etc/my.cnf.d/z-custom-my.cnf
On Debian and Ubuntu, a good custom configuration file would be: /etc/mysql/mariadb.conf.d/z-custom-my.cnf
Set your system variables and options in the configuration file.
They need to be set in a group that will be read by mariadbd, such as [mariadb] or [server].
For example:
It is a general purpose storage engine.
It is ACID-compliant.
It is performant.
It is the transactional component of MariaDB's single stack Hybrid Transactional/Analytical Processing (HTAP) solution.
row database
A database where all columns of each row are stored together.
Best suited for transactional and OLTP workloads.
Also known as a "row-oriented database".
System Variable/Option
Description
Sets the path to the data directory. MariaDB Community Server writes data files to this directory, including tablespaces, logs, and schemas. Change it to use a non-standard location or to start the Server on a different data directory for testing.
Sets the local TCP/IP address on which MariaDB Community Server listens for incoming connections. When testing on a local system, bind the address to the local host at 127.0.0.1 to prevent network access.
Sets the port MariaDB Community Server listens on. Use this system variable to use a non-standard port or when running multiple Servers on the same host for testing.
