squid7.6正向代理编译安装(包含帐号密码认证功能)

1.下载

wget https://github.com/squid-cache/squid/archive/refs/tags/SQUID_7_6.tar.gz
tar zxf SQUID_7_6.tar.gz 
cd squid-SQUID_7_6/

2.编译安装

创建用户/组

useradd -r -s /sbin/nologin squid

安装 bootstrap 依赖（生成 configure 必需） 在 squid-SQUID_7_6 目录下执行

./bootstrap.sh

#下载最新的config.sub/config.guess（适配AlmaLinux 9/10.1）

wget -O cfgaux/config.sub https://git.savannah.gnu.org/cgit/config.git/plain/config.sub
wget -O cfgaux/config.guess https://git.savannah.gnu.org/cgit/config.git/plain/config.guess
chmod +x cfgaux/config.sub cfgaux/config.guess

编译

./configure \
--prefix=/opt/squid \
--sysconfdir=/opt/squid/etc \
--with-default-user=squid \
--with-openssl \
--with-epoll \
--enable-basic-auth-helpers=NCSA \
--enable-storeio=ufs \
--enable-ssl-crtd

make -j 1 && make install 

安装htpasswd工具

dnf install -y httpd-tools

chown -Rf squid:squid /opt/squid
htpasswd -c /opt/squid/etc/passwd user
chown squid:squid /opt/squid/etc/passwd
chmod 600 /opt/squid/etc/passwd

启动squid

/opt/squid/sbin/squid -k reconfigure

/opt/squid/sbin/squid  -k parse

/opt/squid/sbin/squid -z

/opt/squid/sbin/squid -N -d1

3.关键配置说明

auth_param basic program /usr/lib64/squid/basic_ncsa_auth
调用 squid 自带的basic_ncsa_auth程序读取 htpasswd 格式密码文件；
auth_param basic credentialsttl 2 hours：客户端认证缓存 2 小时，2 小时后重新输密码；
acl authenticated proxy_auth REQUIRED：判定必须通过账号密码；
http_access allow authenticated：任意来源 IP，只要密码正确就放行代理（正向代理）；
