如何删除MySQL服务器，并将其从服务器中删除，因为我没有使用MySQL服务器。如何在基于Ubuntu的系统上卸载MySQL？通常在Debian或者Ubuntu Linux系统上安装以下Mysql软件包：

• mysql-client最新版本的MySQL数据库客户端。
• mysql-server最新版本的MySQL数据库服务器。
• mysql-common MySQL数据库通用文件。

如何卸载Mysql服务器？

只需使用apt-get命令，如下所示，在Ubuntu Linux中删除MySQL服务器和客户端：

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

示例输出(注意包名称)：

使用rm命令删除/etc/mysql /目录：

$ sudo rm -rf /etc/mysql/

了解apt-get命令选项

• --purge：删除给定的软件包和配置文件。
• remove：卸载软件包。
• autoremove：强制删除自动安装的软件包，以满足其他软件包的依赖性，现在不再需要。
