Centos服务器搭建Squid Http代理请求服务器教程
作者：ZeroTeam_麒麟
文章总结了作者在配置系统服务时的个人经验,包括生成密码文件、测试密码文件配置、启动服务、配置副本（包括无权限控制和权限控制）等步骤,并鼓励读者参考和使用脚本之家
安装
yum install squid -y yum install httpd-tools -y
生成密码文件
mkdir /etc/squid3/ #这里密码是 ceshi htpasswd -cd /etc/squid3/passwords ceshi #回车 自己输入密码
测试密码文件
/usr/lib64/squid/basic_ncsa_auth /etc/squid3/passwords #输入账号跟密码 ceshi 123456 #提示 OK 代表正确 OK
配置
vim /etc/squid/squid.conf # 在最后添加 auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid3/passwords auth_param basic realm proxy acl authenticated proxy_auth REQUIRED http_access allow authenticated # 这里是端口号，可以按需修改 # http_port 3128 这样写会同时监听ipv6和ipv4的端口，推荐适应下面的配置方法。 http_port 0.0.0.0:3128
启动服务
# 开启启动 systemctl enable squid.service # 启动 systemctl start squid.service # 停止 systemctl stop squid.service # 重启 systemctl restart squid.service
配置副本–无权限控制
