在 Ubuntu 16.04 中安装 MySQL 时出现配置错误

不幸的是，我卸载了 MySQL。稍后尝试安装时，出现以下错误：

ERROR: Unable to start MySQL server:
mysqld: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 2 - No such file or directory)
mysqld: [ERROR] Fatal error in defaults handling. Program aborted!
Please take a look at https://wiki.debian.org/Teams/MySQL/FAQ for tips on fixing common upgrade issues.
Once the problem is resolved, run apt-get --fix-broken install to retry.

dpkg: dependency problems prevent configuration of mysql-server:

我已尝试以下步骤

  1. 完全删除 MySQL 服务器并尝试再次安装。
  2. sudo dpkg --configure -a
  3. apt-get install -f

但是没用。

您的系统可能缺少某些配置文件。运行以下命令来恢复它们：

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

有可能，您在执行此命令时会收到错误，但文件夹/etc/mysql/conf.d/现在应该在那里。如果命令失败，您必须手动启动 mysql：

service mysql start

然后运行以下命令完成安装：

apt-get install -f mysql-server
