Squid是一个高性能的代理缓存服务器，Squid支持FTP、gopher、HTTPS和HTTP协议。和一般的代理缓存软件不同，Squid用一个单独的、非模块化的、I/O驱动的进程来处理所有的客户端请求
以前配置过，忘记做笔记了，现在重新实践下记录下来
关闭selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config setenforce 0
squid安装比较简单
yum install squid openssl* -y
配置文件在/etc/squid/squid.conf下我们来看看配置文件，可以直直接修改为以下配置
cat /etc/squid/squid.conf

如果是在linux的浏览器上使用代理访问，需要修改/etc/profile文件，在最后追加
export http_proxy=http://172.16.5.131:3128 export https_proxy=http://172.16.5.131:3128
如果是在windows浏览器中使用代理，需要做如下设置
打开浏览器，进入Internet选项→连接→局域网(LAN)设置
为LAN使用代理服务器
地址填写172.16.5.131
端口填写3128即可
