#mysql_install_db
#chown -R mysql:mysql /var/lib/mysql
This gives mysql rights to use it’s own folder and files.
Now you can start mysql
/etc/rc.d/rc.mysqld start
# mysqladmin create akonadi -p
add "user=root" in the Akonadi local mysql configuration file (on my computer, it is /root/.local/share/akonadi//mysql.conf), and Akonadi server can be started successfully.
So root user can use KDE too.
