網上流傳配置多基於 5.1，參數過時導致性能差、數據不一致甚至丟失。本模板覆蓋 5.6/5.7 核心參數，僅需按硬件調整 innodb_buffer_pool_size、innodb_io_capacity 等少量值即可投產。

| 參數 | 調整依據 |
|---|---|
| innodb_buffer_pool_size | 物理內存 70-80%（純 InnoDB） |
| innodb_io_capacity | SSD 4000-8000，HDD 200-500 |
| innodb_log_file_size | 總 4-8GB，單文件 1-2GB |
| max_connections | 業務峰值併發 + 余量 |
| sync_binlog=1 + gtid_mode=on | 數據零丟失、主從一致性基石 |
