First of all, do a backup of your needed databases with mysqldump
首先，备份你需要的数据库 mysqldump
Note: If you want to restore later, just backup your relevant databases, and not the WHOLE, because the whole database might actually be the reason you need to purge and reinstall).
注意：如果您想稍后恢复，只需备份您的相关数据库，而不是整个数据库，因为整个数据库实际上可能是您需要清除和重新安装的原因）。
In total, do this:
总的来说，这样做：
sudo service mysql stop #or mysqld
sudo killall -9 mysql
sudo killall -9 mysqld
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
sudo deluser -f mysql
sudo rm -rf /var/lib/mysql
sudo apt-get purge mysql-server-core-5.7
sudo apt-get purge mysql-client-core-5.7
sudo rm -rf /var/log/mysql
sudo rm -rf /etc/mysql
All above commands in single line (just copy and paste):
以上所有命令都在一行中（只需复制和粘贴）：
sudo service mysql stop && sudo killall -9 mysql && sudo killall -9 mysqld && sudo apt-get remove --purge mysql-server mysql-client mysql-common && sudo apt-get autoremove && sudo apt-get autoclean && sudo deluser mysql && sudo rm -rf /var/lib/mysql && sudo apt-get purge mysql-server-core-5.7 && sudo apt-get purge mysql-client-core-5.7 && sudo rm -rf /var/log/mysql && sudo rm -rf /etc/mysql

You need to remove the /var/lib/mysql folder. Also, purge when you remove the packages (I'm told this helps).
您需要删除 /var/lib/mysql 文件夹。另外，当你移除包裹时清除（我被告知这有帮助）。
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo rm -rf /var/lib/mysql
sudo rm -rf /var/lib/mysql
I was encountering similar issues. The second line got rid of my issues and allowed me to set up MySql from scratch. Hopefully it helps you too!
我遇到了类似的问题。第二行解决了我的问题，并允许我从头开始设置 MySql。希望对你也有帮助！

Run these commands in the terminal:
在终端中运行这些命令：
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
Run these commands separately as each command requires confirmation & if run as a block, the command below the one currently running will cancel the confirmation (leading to the command not being run).
单独运行这些命令，因为每个命令都需要确认，如果作为一个块运行，当前运行的命令下面的命令将取消确认（导致命令未运行）。
