无法启动Squid代理

Question

我的乌贼代理有点问题。代理关闭后，我无法启动代理。据我所知，从昨天起我没有碰过任何鱿鱼的配置。今天早上，我来到办公室，看上去就像倒下了一样。请参阅下面的cache.log：

请给我建议。

Answer 1

Perl模块NTA/database/TechDb.pm丢失并导致程序退出。

CPAN和Google找不到任何关于它的信息。

你在用什么操作系统乌贼？这是专有的东西吗？为什么您的系统上有/opt/nta和/opt/squid_auth下面的内容？这不是标准的。您的系统是以某种不寻常的方式配置的。

Answer 2

这个问题已经解决了。与其说模块不在路径上，不如说是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，因为当它被更新时，它返回到“扫描:techdata”默认值。因此，我将模块提交给SVN，以使其与其他服务器保持不变，这意味着权限不会从“代理”用户更改。

谢谢

Answer 3

解决这一问题的更好方法是使用组成员身份，这是POSIX系统中应该使用的方式。

• 从cache_effective_group中删除squid.conf设置
• 将代理用户添加为techdata组的成员(读取模块)。
