############################################### 模式1：Squid對應多臺web服務器
在vi /etc/hosts中：加入內部的DNS解析，比如：
192.168.0.9??? www.winkee.com
192.168.0.66??? bbs.winkee.com
A2、#vi /Data/apps/squid/etc/squid.conf
代碼如下：
# visible name
visible_hostname cache.winkee.com
# cache config: space use 1G and memory use 256M
cache_dir ufs /Data/apps/squid/cache 1024 16 256
cache_mem 256 MB
cache_effective_user squid? #設置運行時的用戶和組權限
cache_effective_group squid
# 反向加速配置
http_port 80?? # squid監聽的端口,客戶訪問網站的端口
httpd_accel_host virtual? # WEB服務器的IP地址,此模式下設置為:virtual

# logfile_rotate 可以用logfile_rotate 0來取消自動操作
logfile_rotate 4 Setp ３ –Starting Squid
１、??? 創建緩存目錄
# cd /Data/apps/squid/sbin
#./squid –z?? # 出現Creating Swap Directories提示，表示建立成功
２、??? 運行Squid
# cd /Data/apps/squid/sbin
#./squid –NCd1 # 成功后將出現"Ready to serve requests".否則請檢查配置文件
說明，用squid -NCd1來以debug模式啟動，這樣如果有錯誤會報出來，一般如果是ADSL撥號的，那么在沒有撥號之前就啟動squid的話是會出錯的(FATAL: ipcache_init: DNS name lookup tests failed)，因為squid啟動時會去檢查一些常用的DNS，但是這時候你并沒有接入internet，自然就出錯了，所以我們需要在啟動的時候不檢查DNS，這就需要用加上-D選項來啟動squid，命令如下：
#./squid –NCDd1 # 參數Dd1的目的是禁止測試DNS的連通性并且把squid在開始運行后的一些提示信息顯示在屏幕上) 注意事項：
1、Squid的配置文件squid.conf更改后必須重新運行squid
2、Squid服務器的hosts文件更改后必須重新運行squid
