在 64 位 Ubuntu 可信服务器上：
我有 MariaDB 10.1 和不同的 datadir 工作
datadir=/mnt/SRVDATA/var/lib/mysql
昨天我收到了更新 10.1.13-MariaDB-1~trusty 来自
deb http://mirror.netcologne.de/mariadb/repo/10.1/ubuntu trusty main
MariaDB 不会再启动了。
我重命名了 /etc/mysql、/usr/lib/mysql 和 /var/lib/mysql 并重新安装了 MariaDB 服务器和客户端。我进行了 dpkg-reconfigure 并在 /var/lib/mysql 中获得了一个新的原始数据库。有了它，我可以启动 MariaDB。
我再次将 /var/lib/mysql 复制到具有所有权限的 /mnt/SRVDATA/var/lib/mysql ，我将 my.cnf 更改为将 datadir 指向 /mnt/SRVDATA/var/lib/mysql 但 MariaDB 不会启动。
Apparmor 已关闭，它的配置文件已拆除。
