出现错误：mysql.service 失败，因为控制进程退出并出现错误代码。安装docker后

Question

我已经在我的 ubuntu 21 系统上安装了 MySQL-server，当我尝试启动 MySQL-Server 时，我得到了Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xeu mysql.service" for details. 安装 docker 并在其上运行 MySQL 之前，我得到 \nit 工作正常

我尝试了这个并且它有效：

sudo apt autoremove --purge mysql-server\* mariadb-server\*
sudo rm -rf /var/lib/mysql
sudo rm -rf /etc/mysql/
sudo mkdir -p /etc/mysql/conf.d
sudo apt install mysql-server

注意：请务必备份您的数据，因为这些命令将删除您的所有MySQL数据。
