This why I was asking if DA is "binded" to MariaDB.
Code:
/usr/local/directadmin/custombuild/build opt_help
------------------------------------------
MySQL Settings
------------------------------------------
mysql: 8.0. Current value: 8.0. Default value: 8.0.
mariadb: 10.3, 10.4, 10.5, 10.6. Current value: 10.6.
Default value: 10.6.
mysql_inst: mysql, mariadb, no. Current value: mariadb.
Default value: mariadb.
mysql_backup: yes, no. Current value: yes. Default value: yes.
mysql_backup_gzip: yes, no. Current value: yes. Default value: no.
mysql_backup_dir: userinput. Current value: /sys_backup/mysql_backups. Default value: /usr/local/directadmin/custombuild/mysql_backups.
mysql_force_compile: yes, no. Current value: no. Default value: no.
Yes the default install is MariaDB
I think is the question.
