MySQL

Standalone MySQL Server 8, tuned for remote access.

About

Installs MySQL Server and configures it to listen on all interfaces so it can be reached from other instances on your private network. A root password is generated automatically.

Restrict the firewall's source CIDR to your own private subnet — do not expose 3306 to 0.0.0.0/0. Root password is in /root/mysql-credentials.txt.

Ports opened by the installer
