NOTE
Installing and Configuring MySQL
A version-aware checklist for installation, initialization, security, durability, memory, and observability.
This is a historical learning note and may contain outdated or incomplete understanding.
Prefer a maintained package, container image, or managed service and pin an explicit supported MySQL version. Initialize data securely, set authentication/privileges, configure backups, and verify recovery before production use.
Important settings include memory/buffer-pool sizing, connection limits, redo/binlog durability, character set/collation, time zone, logging, and replication parameters. Do not copy an old my.cnf wholesale: defaults and valid variables change across major versions.
