无法卸载 MariaDB

Question

我尝试重新安装 MariaDB，我使用了：

sudo apt-get purge mysql* mariadb*

但是在上述尝试失败后，唯一需要卸载的软件包是mariadb-server-10.0.

当我尝试使用以下方法清除它时：

sudo apt-get purge mariadb-server-10.0

我得到了这个输出：

Use 'apt-get autoremove' to remove them.

我应该如何继续尝试解决此问题？谢谢

MariaDB 是 MySQL 的开源版本（没有任何父级 Oracle 的麻烦）。你需要从MariaDB的安装日志中找到MySQL安装在哪里（可能在/etc/init.d下）然后停止它

sudo /etc/init.d/mysql stop

完成后，请执行您尝试执行的相同操作。
