简单的Nginx+Squid+Tomcat架构

架构拓扑图：

配置细节：

 1. #Ninx Conf

}

server

 

    {

        listen  80;

 

        server_name www.andylhz.com;

 

    location / {

 

        proxy_pass http://www.andylhz.com:8889;

      }

        

#图片的访问转发给Squid

location  ~* .*\.(gif|png|jpg|jpeg|bmp|swf)$ {

 

        proxy_pass http://www.andylhz.com:9999;

 

        }

}

                   '"$status" $body_bytes_sent "$http_referer" '

                   '"$http_user_agent" "$http_x_forwarded_for"';

 

access_log  /usr/local/nginx/logs/access.log  access;

    }

 

 

 

 

2. #Squid Conf

 

 

 

http_port 172.16.0.246:9999   vhost vport   #监听本机的9999的端口

 

 

acl OverConnLimit maxconn 100

http_access deny OverConnLimit

 

 

acl Manager proto cache_object

acl Localhost src 127.0.0.1 172.16.0.246   #访问控制

http_access allow Manager Localhost

http_access deny Manager

 

visible_hostname www.andylhz.com

cache_mgr [email protected]

cache_effective_user squid

cache_effective_group squid

tcp_recv_bufsize 65535 bytes

 

cache_dir ufs /usr/local/squid/var/cache 100 16 256

cache_store_log /usr/local/squid/var/logs/store.log

cache_log /usr/local/squid/var/logs/cache.log

forwarded_for on

logformat combined %>a %ui %un [%tl +0800] "%rm %ru HTTP/%rv" %Hs %<st "%{Referer}>h" "%{User-Agent}>h" %Ss:%Sh

access_log /usr/local/squid/var/logs/access.log combined

 

#缓存本机tomcat的内容

cache_peer 172.16.0.246 parent 8889  0 no-query originserver name=a round-robin  

 

3. #Tomcat conf

 

 

配置Tomcat使用端口8889端口。
