提高squid缓存的命中率
安装运行squid后用命令squidclient -t 1 -h localhost -p 80 mgr:info 查看命中率情况Request Hit Ratios: 5min: 99.6%, 60min: 98.7% Cache Request命中率 Byte Hit Ratios: 5min: 100.0%, 60min: 100.0% Cache Byte命中率
如果命中率低 则1apache中的模块 mod_expires是否打开
2调整squid中的参数# cache_mem 8 MBcache_mem 64 MB# maximum_object_size 4096 KBmaximum_object_size 16384 KB# maximum_object_size_in_memory 8 KBmaximum_object_size_in_memory 256 KB# ipcache_size 1024ipcache_size 2048#Default:cache_dir ufs /usr/local/squid/cache 2048 32 5123如果apache中使用了deflate压缩 设置 cache_vary on4 如果用nginx 可以用第三方模块mod_urlhash 提高命中率
