在Ubuntu或Debian系统的服务器上卸载MySQL的方法

对于有的vps，系统默认安装了mysql。我们需要从我们的服务器、vps上卸载(移除)默认的mysql。那么如何(怎样)在ubuntu\debian上卸载mysql?

通常情况下，下列mysql软件包会被安装到 debian 、ubuntu中：

• mysql-client - the latest version of mysql database client(最新版的mysql数据库客户端).
• mysql-server - the latest version of mysql database server.(最新版的mysql数据库服务端)
• mysql-common - mysql database common files(mysql数据库命令文件)

那么如何怎样在ubuntu\debian上卸载mysql？
只需要使用 apt-get 命令 即可，如下面的命令，同时卸载 ubuntu \ debian 中的 mysql server 和 mysql client ：

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

解释: --purge 移除所给的软件包和配置文件

remove 表示卸载软件包

autoremove 表示自动卸载软件包，以及与该软件包的依赖(软件包)

输入如下(注意软件包名字)：
