yumlist 获取yum列表

如果出现列表数据如下这种表示设置成功

sqlite-devel.i3863.3.6-7basesqlite-devel.x86_643.3.6-7basesquashfs-tools.x86_643.0-4basesquirrelmail.noarch1.4.8-21.el5.centosbasesrptools.x86_640.0.4-10.el5basesssd.x86_641.5.1-70.el5basesssd-client.i3861.5.1-70.el5basesssd-client.x86_641.5.1-70.el5basesssd-tools.x86_641.5.1-70.el5base

2、安装squid

squid介绍及其简单配置

前面准备好yum命令可以直接在线安装

yuminstallsquid 安装完成后cd /etc/squid/目下修改squid.conf文件中的内容修改之前可以先备份该文件

cpsquid.confsquid.conf_bak 然后找到文件中的http_accessdenyall 将其修改为http_accessallowall 表示所有用户都可以访问这个代理

还有找到 http_port3128 修改为 http_port192.168.3.171:3128 这里的IP及端口是squid的代理IP及端口

该IP是能访问外网机器的IP地址如果是本机则可以不用修改该地址下面启动squid代理
