下载deb包

https://downloads.mysql.com/archives/community/

这里以mysql5.7.32为例

点击下载，然后解压

安装

安装要有顺序，common、lib、client、server，中间可能会缺少依赖，用apt安装一下或者去 https://pkgs.org/ 找一下相关的deb包。具体是啥我忘了

sudo dpkg -i mysql-common_5.7.32-1debian10_amd64.deb
sudo dpkg -i libmysqlclient20_5.7.32-1debian10_amd64.deb
sudo dpkg -i mysql-community-client_5.7.32-1debian10_amd64.deb
sudo dpkg -i mysql-client_5.7.32-1debian10_amd64.deb
sudo dpkg -i mysql-community-server_5.7.32-1debian10_amd64.deb
