mysql Ver 8.0.31-0ubuntu2 for Linux on aarch64 ((Ubuntu))
- 第一步 ：更新软件包
sudo apt update - 第二步 ：直接安装最新 mysql

mysqlsudo mysql --user=root mysql - 第七步：输入mysql命令，执行完成以后刷新一下
UPDATE mysql.user SET authentication_string=null WHERE User='root';
flush privileges; - 第八步 ：修改mysql密码并刷新
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'superman';
flush privileges; - 重启 ：
sudo /etc/init.d/mysql start - 下面我们还可以设置mysql开机自启动：
sudo update-rc.d -f mysql defaults - 查看是否自启动：
sudo service mysql status - 查看mysql运行状态：
sudo service mysql status - mysql开启：
sudo service mysql start - mysql停止：
sudo service mysql stop
