A few moments ago I received an email from Archlinux advising that from now on MariaDB will become the official MySQL implementation, moving this to AUR next month and that the same will happen in the next version of Slackware.
MariaDB is a fork of MySQL created by the founder of MySQL, Michael Widenius after the purchase of Sun Microsystems by Oracle and that is fully compatible, including libraries and modules of PHP, Python, Perl.
To change in Archlinux you just have to follow these steps:
systemctl stop mysqld
pacman -S mariadb libmariadbclient mariadb-clients
systemctl start mysqld
Will this mean the beginning of the true end of MySQL?
