It’s always a good idea to do basic MySQL security measures after installing fresh version of MariaDB server. For this task, I always used “mysql_secure_installation” command, which was part of installation. Some time ago, I’ve got stucked when trying to do so on MariaDB version 10.7. After some searching around, I guess command was changed.
[root@server ~]# mysql_secure_installation
-bash: mysql_secure_installation: command not found
This is a correct way on newer MariaDB versions:
root@server ~]# mariadb-secure-installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
