怎么恢复 Apache HTTP Server 的默认配置?
下载文件,把 /etc/apache2/conf.d/userdir.conf 里的当前配置备份好,替换掉,然后 reload 或 restart Apache HTTP Server。
userdir.conf 适合直接上生产吗?
这是 Alpine Linux v3.21 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 Alpine Linux v3.21。
我可以用它来排查 Apache HTTP Server 吗?
可以。和你的配置做 diff 找出漂移,然后只恢复需要的段落。
