# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.

FAQ

什么时候该用这个 my.cnf？

用来恢复缺失的默认文件、确认发行版本带了什么，或拿你的 MariaDB config 做 diff。

怎么恢复 MariaDB 的默认配置？

下载文件，把 /etc/my.cnf 里的当前配置备份好，替换掉，然后 reload 或 restart MariaDB。

my.cnf 适合直接上生产吗？

这是 CentOS Stream 9 的厂商默认配置，只能当基线。上生产前请检查安全和性能设置。

和其他 OS 版本有什么不同？

默认值会随发行版和版本变化，这份对应 CentOS Stream 9。

我可以用它来排查 MariaDB 吗？

可以。和你的配置做 diff 找出漂移，然后只恢复需要的段落。
