我花了几个小时试图将我的 Apache 服务器配置为使用没有公共 IP 的 SSL，只有 localhost。我已经创建了证书，我认为（这对我来说就像一个关于黑魔法的速成课程），当我尝试访问https://localhost时，浏览器在状态行，但只是永远加载。这是来自的片段error_log：

那里一切似乎都还好，但与此同时，在ssl_engine_log...

一些关于这个permission denied的谷歌搜索和apr_proc_mutex_lock失败并没有产生任何有用的东西。只有一些与 MPM 和 perchild 选项相关的结果，但由于它们很旧（2002 年和 2003 年）而且我在阅读它们后真的不能得出任何结论，我问你是否有办法克服这个问题。好吧，首先：实际上是什么问题？模块之间是否存在某种不兼容？我是否必须重新编译某些东西（请主，不要再编译了，不）？
