我的 Squid 代理出现了一些问题。代理关闭后，我无法启动代理。据我所知，从昨天开始，我没有动过任何 Squid 配置。然后今天早上我来到办公室，它看起来好像已经关闭了。请参阅以下内容cache.log：

请指教。
答案1
Perl 模块NTA/database/TechDb.pm丢失，导致程序退出。
CPAN 和 Google 都找不到关于它的任何信息。
您在什么操作系统上使用 Squid？这是专有的东西吗？为什么下面有东西/opt/nta和/选择/squid_auth您的系统上是否安装了？这不是标准的。您的系统配置方式有些不同寻常。
答案2
这个问题已经解决。问题并不在于模块不在路径中，而在于最近的引擎更新覆盖了 TechDb.pm 模块的权限。问题是作为“代理”运行的 squid 服务无法读取 perl 模块，因为更新后，它恢复为“scans:techdata”默认值。因此，我已将模块提交给 SVN，以使其与其他服务器保持一致，这意味着权限不会因“代理”用户的更改而改变。
谢谢
答案3
解决这个问题的更好方法是按照 POSIX 系统中应该使用的方式使用组成员身份。
从 squid.conf 中删除 cache_effective_group 设置
将代理用户添加为 techdata 组的成员（以读取模块）。
