A month ago the Mariadb server and client worked perfectly with phpMyAdmin, but since I reinstalled the entire system I have appeared in the SSH console:

/opt/bin/mysql_install_db --user=admin --basedir=/opt --datadir=/opt/var/mysql/ --lc-messages-dir=/opt/share/mariadb

Installing MariaDB/MySQL system tables in '/opt/var/mysql/' ...

OK

Impossible to start the server with the command:

/opt/etc/init.d/S70mysqld start

Is it possible to deactivate the MADV_DODUMP function ?. The "-core-file" and "-innodb-buffer-pool-in-core-file" commands do not exist in this system Linux.

I have a previous backup and this does not happen.
