PS：

apache的log顯示ip來源都是127.0.0.1,修改配置文件使其可以正常記錄來訪IP

修改前：

LogFormat?"%h?%l?%u?%t?\"%r\"?%>s?%b?\"%{Referer}i\"?\"%{User-Agent}i\""?combined?

修改后

LogFormat?"%{X-Forwarded-For}i?%l?%u?%t?\"%r\"?%>s?%b?\"%{Referer}i\"?\"%{User-Agent}i\""?combined?

快速清空cache

echo "" >?/usr/local/squid/var/cache/swap.state?

對于類似http://xxx.xxx.xxx/default.html之類的網(wǎng)頁，squid只會生成一個(gè)緩存文件。可以用squid附帶的squidclient工具清除：

squidclient?-m?PURGE?-p?80?"http://xxx.xxx.xxx/default.html"?

squid命中率查看

squidclient?-p?80?-U?Henry?-W?xxxx?mgr:info?|grep?-i?hit?

????????Hits?as?%?of?all?requests:??????5min:?62.1%,?60min:?64.1%?

????????Hits?as?%?of?bytes?sent:????????5min:?63.4%,?60min:?60.6%?

????????Memory?hits?as?%?of?hit?requests:???????5min:?97.3%,?60min:?89.7%?

????????Disk?hits?as?%?of?hit?requests:?5min:?0.2%,?60min:?0.1%?

????????Cache?Hits:????????????0.00000??0.00000?

????????Near?Hits:?????????????0.00091??0.00091?

內(nèi)存使用情況：

squidclient?-p?80?-U?Henry?-W?password?mgr:mem

該指令可以看到在squid運(yùn)行過程中，有那些文件被squid緩存到內(nèi)存中，并返回給訪問用戶。

tail?-f?/usr/local/squid/var/logs/access.log?|grep?TCP_MEM_HIT?

該指令可以看到在squid運(yùn)行過程中，有那些文件被squid緩存到cache目錄中，并返回給訪問用戶。

tail?-f?/usr/local/squid/var/logs/access.log?|grep?TCP_HIT??

該指令可以看到在squid運(yùn)行過程中，有那些文件沒有被squid緩存，而是現(xiàn)重原始服務(wù)器獲取并返回給訪問用戶。

tail?-f?/usr/local/squid/var/logs/access.log?|grep?TCP_MISS?
