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
1 apache中的模块 mod_expires是否打开
2 调整squid中的参数
# cache_mem 8 MB cache_mem 64 MB # maximum_object_size 4096 KB maximum_object_size 16384 KB # maximum_object_size_in_memory 8 KB maximum_object_size_in_memory 256 KB # ipcache_size 1024 ipcache_size 2048 #Default: cache_dir ufs /usr/local/squid/cache 2048 32 512 3 如果apache中使用了deflate压缩
设置 cache_vary on 4 如果用nginx 可以用第三方模块mod_urlhash 提高命中率
