使用squid快速搭建代理

如何使用squid快速搭建代理
=======本项目主要介绍如何利用国外VPS搭建多协议代理服务。GFW 封锁了 HTTP/Socks5 代理，HTTP 代理是关键词过滤，Socks5 代理则是封锁协议。不过某些特殊的低端口并没有这么处理，已知的有 21，25。20端口已经被封杀，21端口目前会被限速400Kbps，换算后约合50KB/S，建议使用25端口，不限速。搭建代理服务器==============在 25 端口搭建 http/https 代理。Ubuntu:

apt-get install squid
curl https://pac.itzmx.com/squid/ubuntu-squid.conf >> /etc/squid3/squid.conf
/etc/init.d/squid restart

Centos:

setenforce 0
ulimit -n 1048576
echo "* soft nofile 1048576" >> /etc/security/limits.conf
echo "* hard nofile 1048576" >> /etc/security/limits.conf
killall sendmail
/etc/init.d/postfix stop
chkconfig --level 2345 postfix off
yum -y install squid
wget -O /etc/squid/squid.conf https://pac.itzmx.com/squid/centos-squid.conf /etc/init.d/squid restart
chkconfig --level 2345 squid on

不知道能否使用，先收藏找时间试试
