Mariadb 10.3.8：从 MariaDB 存储库安装，缺少文件？

Question

我已经在 Ubuntu 18 服务器上安装了 MariaDB 10.3.8，如下：

sudo apt-get install software-properties-common
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8
sudo add-apt-repository 'deb [arch=amd64,arm64,ppc64el] http://sfo1.mirrors.digitalocean.com/mariadb/repo/10.3/ubuntu bionic main'
sudo apt update
sudo apt install mariadb-server
sudo apt install mariadb-client

它没有开始：

sudo service mariadb start
Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.

日志：

systemctl status mariadb.service
? mariadb.service - MariaDB 10.3.8 database server
Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled)

  Main PID: 3359 (code=exited, status=0/SUCCESS)

状态：“MariaDB 服务器已关闭”

然后，我看到一个丢失的文件：

sudo ls -l /etc/mysql/debian-start
ls: cannot access '/etc/mysql/debian-start': No such file or directory

其他文件丢失：

/etc/mysql/my.cnf
/etc/mysql/conf.d
/etc/mysql/mariadb.cnf
/etc/init.d/mysql

我找到了一个解决方案：

以下命令：

apt-get install --reinstall -o Dpkg::Options::="--force-confmiss" mariadb-server-10.3

创建了一些文件：

/etc/mysql/conf.d
/etc/init.d/mysql
/etc/mysql/debian-start

和：

apt-get install --reinstall -o Dpkg::Options::="--force-confmiss" mysql-common

创建：

/etc/mysql/my.cnf
