今天早上我发现，MariaDb在从 FreeBSD 10.3 升级到 11.1 的过程中，该库已被从我的服务器中删除。在重新安装数据库引擎并解决my.cnf不兼容问题后，我终于可以MariaDb工作了——但现在每一个用户（非 root）被拒绝访问其数据库。
我尝试为随机用户重置密码，但没有任何作用。
server.err关于这里出了什么问题的有用信息在哪里？这是重新启动数据库后的所有信息：

在我开始升级 FreeBSD 之前，这是一个可以正常工作的服务器。我没有做任何事情来更改任何数据库或文件的权限，事实上，我唯一做的事情做过改变的是操作系统和数据库引擎——我会预期的对数据透明的“升级”！

我检查了输出mysql_upgrade，发现有很多与系統数据库。我不知道这些是否相关，或者我可以或应该对它们做什么：

注意：在这两个编辑中，“OK”表都被删除了，以减少问题中文本的大小。
我再次重新运行mysql_upgrade，因为我找到的搜索结果是“mysql_upgrade 无法从 mysql.proc 加载。表可能已损坏“所有迹象表明，这些问题可以通过运行来解决mysql_upgrade。（我不得不运行，mysql_upgrade -p --force因为没有--force参数，它只是说”此安装的 MySQL 已升级至 10.2.13-MariaDB“)
现在我得到了一组同样不透明的错误消息。（下面每种情况下的序列invalid table(s) ... to use them都可以扩展为invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them- 我必须进行这些替换才能适应 30000 个字符的问题长度限制。）
