###############################################
模式1：Squid对应多台web服务器
在vi /etc/hosts中：加入内部的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
代码如下：
# 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  #设置运行时的用户和组权限
cache_effective_group squid
# 反向加速配置
http_port 80   # squid监听的端口,客户访问网站的端口
httpd_accel_host virtual  # WEB服务器的IP地址,此模式下设置为:virtual
httpd_accel_single_host off  # 设置on时缓冲请求到单台Server，off对应virtual
httpd_accel_port 80  # WEB服务器的端口(对于多台web服务器,端口必须一致)
httpd_accel_uses_host_header on  # 完成多个WEB服务器的反向代理功能
httpd_accel_with_proxy off    # 停用代理本地上网
# accelerater my domain only
acl HostA dstdomain  www.winkee.com
acl HostB dstdomain  bbs.winkee.com
# accelerater http protocol on port 80
acl acceleratedProtocol protocol HTTP
acl acceleratedPort port 80
# access arc
acl all src 0.0.0.0/0.0.0.0
# Allow requests when they are to the accelerated machine AND to the right port with right protocol
http_access allow acceleratedProtocol acceleratedPort HostA
http_access allow acceleratedProtocol acceleratedPort HostB
http_access allow all
# logging
emulate_httpd_log on
cache_store_log none
# manager
acl manager proto cache_object
http_access allow manager all
cachemgr_passwd pass all
cache_mgr admin@winkee.com
#swap 性能微调
half_closed_clients off
cache_swap_high 100%
cache_swap_low 95%
maximum_object_size 1024 KB
# 控制对象的超时时间 (S_Data-Data)
