优化Debian Apache缓存策略可从以下方面入手:
启用缓存模块
确保mod_cache和mod_cache_disk模块已启用:
sudo a2enmod cache cache_disk  
sudo systemctl restart apache2  
配置缓存存储
CacheRoot "/var/cache/apache2/mod_cache_disk"  
CacheDirLevels 2  
CacheDirLength 1  
mod_cache_socache)提升速度。设置缓存规则
<FilesMatch "\.(jpg|css|js)$">  
  Header set Cache-Control "max-age=31536000, public"  
</FilesMatch>  
CacheIgnoreHeaders Set-Cookie  
CacheIgnoreNoLastMod On  
结合压缩优化
启用mod_deflate压缩静态资源,减少传输体积:
sudo a2enmod deflate  
配置压缩类型:
AddOutputFilterByType DEFLATE text/html text/css application/javascript  
调整并发与资源限制
event或worker)并优化参数:<IfModule mpm_event_module>  
  StartServers 2  
  MaxRequestWorkers 150  
  MaxConnectionsPerChild 1000  
</IfModule>  
KeepAlive On  
KeepAliveTimeout 5  
监控与调优
apachectl status或第三方工具(如mod_status)监控缓存命中率。高级方案:
