Question

到目前为止，我已经尝试了以下命令：

sudo apt-get remove mysql-server mysql-client mysql-common
sudo apt-get purge mysql-server mysql-client mysql-common
sudo apt-get autoremove

但每当我尝试使用以下命令找到MySQL时，我会得到一个与MySQL相关的文件列表：

shell>> locate mysql

输出：

我现在该怎么办？

我试图找出是否有任何方法可以删除所有MySQL相关文件，然后重新安装MySQL。

我需要它用于Qt连接。

Answer 1

使用命令：

sudo apt-get remove --purge mysql\*

您可以删除与名为mysql的软件包相关的任何内容。这些命令仅适用于基于debian / debian的Linux发行版（例如Ubuntu）。

您可以使用以下命令列出所有已安装的mysql包：

sudo dpkg -l | grep -i mysql

要更多地清理包缓存，可以使用以下命令：

sudo apt-get clean

另外，请记住使用命令：

sudo updatedb

否则“locate”命令将显示旧数据。

要再次安装mysql，请使用以下命令：

sudo apt-get install libmysqlclient-dev mysql-client

这将安装mysql客户端，libmysql及其头文件。

要安装mysql服务器，请使用以下命令：

sudo apt-get install mysql-server

Answer 2

@ dAm2k的答案只是一点点补充：

除sudo apt-get remove --purge mysql\*

之外

我做了sudo apt-get remove --purge mariadb\*。

我似乎在debian（stretch）的新版本中，当你安装mysql时，用它安装mariadb包。

希望它有所帮助。

Answer 3

即使在我运行时执行 mysql remove 命令和删除 Mariadb 的命令


    sudo dpkg -l | grep -i mysql

我仍然得到以下输出，其中显示了来自 mysql 服务器的文件

pi@Home:/ $ sudo dpkg -l | grep -i mysql
ii  mysql-common                          5.8+1.0.5                              all          MySQL database common files, e.g. /etc/mysql/my.cnf
ii  php-mysql                             2:7.3+69                               all          MySQL module for PHP [default]
ii  php7.3-mysql                          7.3.27-1~deb10u1                       armhf        MySQL module for PHP
ii  phpmyadmin                            4:4.6.6-5                              all          MySQL web administration tool

但是当我运行以下命令时，我没有得到 mysql 的迹象


> pi@Home:/ $ sudo mysql sudo: mysql: command not found pi@Home:/ $ sudo
> service mysql restart Failed to restart mysql.service: Unit
> mysql.service not found.

什么意思？如果删除了 mysql 那为什么我还在查看这些文件，如果我重新安装 mysql 不会干扰新的安装

如何使用配置文件和库文件完全删除MySQL？
