Mariadb 10.3.8 : Installation from MariaDB repo , 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

  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

Answer 1

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
