# cache cleaning is done by htcacheclean, which can be configured in # /etc/default/apache2 # # For further information, see the comments in that file, # /usr/share/doc/apache2/README.Debian, and the htcacheclean(8) # man page. # This path must be the same as the one in /etc/default/apache2 CacheRoot /var/cache/apache2/mod_cache_disk # This will also cache local documents. It usually makes more sense to # put this into the configuration for just one virtual host. #CacheEnable disk / # The result of CacheDirLevels * CacheDirLength must not be higher than # 20. Moreover, pay attention on file system limits. Some file systems # do not support more than a certain number of inodes and # subdirectories (e.g. 32000 for ext3) CacheDirLevels 2 CacheDirLength 1

什么时候该用这个 cache_disk.conf?
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 Apache HTTP Server config 做 diff。
怎么恢复 Apache HTTP Server 的默认配置?
下载文件,把 /etc/apache2/mods-available/cache_disk.conf 里的当前配置备份好,替换掉,然后 reload 或 restart Apache HTTP Server。
cache_disk.conf 适合直接上生产吗?
这是 Ubuntu 24.04 LTS (Noble Numbat) 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 Ubuntu 24.04 LTS (Noble Numbat)。
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。
