先卸载
Ubuntu18.04彻底删除MySQL数据库
1.首先在终端中查看MySQL的依赖项：dpkg --list|grep mysql
2.卸载： sudo apt-get remove mysql-common
3.卸载：sudo apt-get autoremove --purge mysql-server-5.7
4.清除残留数据：dpkg -l|grep ^rc|awk '{print$2}'|sudo xargs dpkg -P
5.再次查看MySQL的剩余依赖项：dpkg --list|grep mysql
6.继续删除剩余依赖项，如：sudo apt-get autoremove --purge mysql-apt-config
