MySQL / MariaDB on production servers
So apparently, after installing a MySQL or MariaDB server you are supposed to run
mysql_secure_installation to adjust the default ease-of-use just-work defaults to a more adequate production server setup.
sudo apt-get update sudo apt-get install mariadb-server sudo mysql_secure_installation
Good to know this useful utility exists, and guides you through setting a root account password, removing the public, anonymous access account, the all-accessible test DB, and only allowing login to root from localhost.
It’s a shame you just have to know about this command though. I can understand the priorities though. After installation, it’s supposed to just work and try out – to please new users. I wonder if the Debian/Ubuntu package installation should be running this utility after installation though, rather than just asking for a root password. It could just ask whether this is a “test or development” installation, or a production installation and then guide you through further. That would probably make for a lot more, secure installations on the internet and elsewhere.
