Squid 3的多域名加速基本配置

#groupadd squid

#useradd -s /sbin/nologin -d /dev/null -g squid squid

#wget

用tar命令把文件解压出来 进入squid目录进行编译安装

#./configure --prefix=/usr/local/squid --enable-follow-x-forwarded-for --enable-storeio=aufs,ufs --with-maxfd=65536 --with-pthreads --enable-dlmalloc --enable-poll --enable-stacktraces --enable-removal-policies=heap,lru --enable-delay-pools

#make(这里可能会编译很久 请耐心等待)

#make install（安装也是一样）

安装完成后，我们进入/usr/local/squid/etc目录编写squid.conf文件。可以把自带的删除 然后自己用vi命令重新写一份，这样比较快。

配置文件如下

# squid conf etc/squid.conf
# Last Updated 2010.11.20

编辑好后保存退出。这里我们可以把Squid写成服务让他开机自动启动，具体设置方法可以见上遍文章。
