[导入]Freebsd 7.0 下用squid做本地Web加速代理

实例环境：
服务器配置：Intel(R) Xeon(TM) CPU 2.80GHz +1G MEM+SCSI 73G
操作系统：Freebs7.0 Realese
机器IP地址：192.168.0.14
本地Web服务器端口为8080

1．先升级ports

#cd /usr/share/examples/cvsup
#cvsup -g -L 2 ports-supfile

2．装最新squid2.6

#cd /usr/ports/www/squid/
#make install clean
#rehash

3．编辑squid.conf文件
为了省时间，删除原配置文件后重新建立一个
以下是本人配置文件关键部分

cache_effective_user squid
cache_effective_group squid

icp_port 0
cache_peer 192.168.0.14 parent 8080 0 no-query originserver

保存退出

创建squid文件系统和日志目录

#mkdir /cache1
#mkdir /cache2
#mkdir /usr/local/squid/var/logs/
#chown –R squid:squid  /cache1
#chown –R squid:squid  /cache2
#chown –R squid:squid  /usr/local/squid/var/log

4．启动调试
#squid –z

前台调试
#squid -NCd1

出现Ready to serve requests.  表示启动正常了  ctrl+c中止
后台启动用
#squid –s
其他一些常用指令

squid.conf 排错。

#squid -k parse  

停止 squid

#squid -k shutdown

重载入修改过的squid.conf

#squid -k reconfigure

Squid开机自动启动
/etc/rc.conf
添加如下行：  
squid_enable = “YES”
还有很多指令可以参考文档
剩下的就是需要根据各业务需要做参数的修改和优化
那么实际本机数据走向为
