最近我在 Ubuntu 18.04 上安装了 squid 代理，它可以很好地处理 http 请求，但我遇到了一些需要 https 连接的应用程序的问题，因此我下载了源代码并使用以下配置选项对其进行了编译：
squid -v
Squid Cache: Version 4.17
Service Name: squid
This binary uses OpenSSL 1.1.1 11 Sep 2018. For legal restrictions on distribution see https://www.openssl.org/source/license.html
configure options: '--enable-ssl-crtd' '--with-openssl'
我想要的只是使用 squid 从远程系统传递 http/https 流量，因为存在一些地理限制，无论使用什么应用程序，但是当我使用 http/https 端口的证书时，根本没有传递任何流量！如果我不使用任何证书，则只有 http 端口有效。
我按照此处提到的说明生成证书（替代方法），创建并初始化 SSL 数据库，并在浏览器和系统范围内导入证书，但仍然没有运气：
安装和配置 Squid Proxy for SSL（Bumping 或 Peek-n-splice）
squid.conf：

那么我在这里做错了什么？正如我之前提到的，我想要的只是通过 squid（如公共代理）不受任何限制地传递所有流量，因此如果有修复方法或任何其他方法，请告诉我。
问候
答案1
尝试通过在前台运行 squid 来排除故障，并查看它在 ubuntu 控制台中给出什么结果
squid -N -d999 -f /etc/squid/squid.conf
- N 表示在前台运行
- d999 显示调试消息
- f 选择 squid 文件配置
在运行 squid 创建文件夹之前，你是否也运行过这个
/usr/local/squid/libexec/security_file_certgen -c-s /usr/local/squid/var/cache/squid/ssl_db -M 4MB
请将 squid 文件夹和所有子文件夹的所有权设置为“代理”（squid 将在 ubuntu 中以“代理”用户身份运行）
- /usr/本地/squid/
