我的FreeRadius服务器已经向南。不知道发生了什么（甚至发生了什么变化），但是现在它不会在启动时或从CLI作为服务启动。该数据库是MariaDB。 Journalctl -xe显示：

正在运行freeradius -C -lstdout -xxx返回有关未使用的东西的一些警告，但指示“配置似乎正常”。当从根目录作为freeradius -X或freeradius -f -lstdout执行时，Freeradius会从CLI运行。
关于在哪里找回去的建议？
我能够解决该问题，但是进行了重建，我相信FreeRadius通过libmysqlclient.so连接到MariaDB的方式存在问题。
我使用以前的书面构建指导来重建新服务器。将sql连接到启用了mods的目录并启动FreeRadius后，引发了相同的错误。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-重新启动后-再次没有错误。
我知道MariaDB和MySQL应该兼容，但是似乎更新破坏了兼容性（至少供我使用）。>>
