MySQL and MariaDB are installed via the same services.mysql configuration.
- MySQL is a widely used open source relational database management system (RDBMS) that offers various features, tools, and services for data warehousing, analytics, machine learning, and more.
- MariaDB is a popular and stable fork of MySQL that is compatible with MySQL and has additional enhancements and features.
Setup MySQL
Setup and enable Mysql database daemon (in this example: latest stable version in nixpkgs)
services.mysql = {
enable = true;
package = pkgs.mysql;
};
Setup MariaDB
Setup and enable MariaDB database daemon (in this example: version 11.0)
services.mysql = {
enable = true;
package = pkgs.mariadb_110;
};
Tips
install `mycli` to get autocompletion when working with mysql/mariadb
environment.systemPackages = [ pkgs.mycli ];
Maintenance
Upgrade
NixOS will not run mysql_upgrade automatically for you after upgrading to a new major version, because it is a "dangerous" operation (can lead to data corruption) and users are strongly advised (by MariaDB upstream) to backup their database before running mysql_upgrade.
mysqldump -u root -p --all-databases > alldb.sql
After backup is completed, you can proceed with the upgrade process
mysql_upgrade
