Squid实现反向代理并且具备内网代理

我的站点上的所有文件都是静态html，为了进一步的加快网页速度，于是使用squid实现反向代理缓存功能。

@ 安装squid

为了偷懒就直接使用ports安装，因为我将所有的服务器系统都安装在/s分区中，所以设置了PREFIX为/s/squid

# cd /usr/ports/www/squid

# setenv PREFIX /s/squid

# make install clean

安装完成后编辑/s/squid/etc/squid/squid.conf，我的配置内容如下：

初始化cache

# /s/squid/sbin/squid -z

启动squid

# /s/squid/etc/rc.d/squid.sh start

@ 设置apache

因为要对外部实现反向透明代理，所以apache不能再在外网IP的80端口服务，我将它设置到127.0.0.1的80端口，修改httpd.conf中的Listen为：

Listen 127.0.0.1:80

刷新apache配置：

# apachectl restart
