ubuntu - FreeRadius 未启动

问题描述

我的 FreeRadius 服务器已经南下。不确定发生了什么（甚至发生了什么变化），但它现在不会在引导时或从 CLI 作为服务启动。数据库是 MariaDB。Journalctl -xe 显示：

运行 freeradius -C -lstdout -xxx 返回一些关于未使用的东西的警告，但表示“配置似乎正常”。当从根目录作为 freeradius -X 或 freeradius -f -lstdout 执行时，Freeradius 确实从 CLI 运行。

关于在哪里寻找让这一切再次发生的任何建议？

解决方案

我能够解决这个问题，但它需要重建，我相信 FreeRadius 如何通过 libmysqlclient.so 连接到 MariaDB 存在问题。

我使用以前编写的构建说明重建了一个新服务器。将 sql 连接到启用 mods 的目录并启动 FreeRadius 后，抛出相同的错误。我查看了所有内容并使用 MySQL 进行了重建，没有错误。然后我复制了原始的 FreeRadius 目录，并且 - 再次启动后 - 没有错误。

我知道 MariaDB 和 MySQL 应该是兼容的，但似乎更新破坏了这种兼容性（至少对我来说是这样）。
