Решение - заменить MARIADB на MySQL 5.6 + сбросить пароли от root/da_admin

# cd /usr/local/directadmin/custombuild/
# vi options.conf
#MySQL Settings
mysql=5.6
#mariadb=10.0

 # ./build update
 # ./build mysql
 # systemctl restart mysqld.service

Если возникает ошибка при установке MySQL:

Error connecting to MySQL: Access denied for user: 'da_admin@localhost' (Using password: YES)

Сбрасываем пароли как написано тут и повторяем процесс:
