1 .安装 squid服务器。squid3 以上版本
修改主配置文件中ip为管理主ip地址
编辑 /etc/squid/squid.conf
http_port x.x.x.x:8000 cache_mgr start@soocol.com cache_effective_user squid cache_effective_group squid cache_mem 128 MB cache_swap_low 90 cache_swap_high 95 cache deny all logformat combined %>a %ui %un [%tl] "%rm %ru HTTP/%rv" %>Hs %<st "%{Referer}>h" "%{User-Agent}>h" %<A access_log stdio:/var/log/squid/access.log combined cache_log /dev/null via off

配置服务器所有可用IP 到配置文件中。 [majun@proxy1 ~]$cat /etc/squid/multi_ips.conf acl random11 random 1/11 acl random10 random 1/10 acl random9 random 1/9 acl random8 random 1/8 acl random7 random 1/7 acl random6 random 1/6 acl random5 random 1/5 acl random4 random 1/4 acl random3 random 1/3 acl random2 random 1/2 acl random1 random 1/1 tcp_outgoing_address x.x.x.x random11 tcp_outgoing_address x.x.x.x random10 tcp_outgoing_address x.x.x.x random9 tcp_outgoing_address x.x.x.x random8 tcp_outgoing_address x.x.x.x random7 tcp_outgoing_address x.x.x.x random6 tcp_outgoing_address x.x.x.x random5 tcp_outgoing_address x.x.x.x random4 tcp_outgoing_address x.x.x.x random3 tcp_outgoing_address x.x.x.x random2 tcp_outgoing_address x.x.x.x random1
可以的话最好是IP可以绑定在lo上，不涉及路由问题。
有的时候IP在不同的网卡上需需要添加策略路由。其中IP需要替换为实际服务器中第二块网卡对应的内网ip。 ip ro add default via 10.0.4.1 dev eth1 table 200 ip ru add from 10.0.4.134 table 200 ip ru add from 10.0.4.21 table 200 ip ru add from 10.0.4.22 table 200 ip ru add from 10.0.4.23 table 200 ip ru add from 10.0.4.24 table 200 ip ru add from 10.0.4.25 table 200
