1.安装mysql
更新仓库：
sudo apt-get update
安装：
sudo apt-get install mysql-server mysql-client
直接安装完成结束
2.不知道密码状态下打开mysql
查询mysql是否运行：
systemctl status mysql
备注：mysql 打开(systemctl start mysql) 关闭(systemctl stop mysql) 重启命令(systemctl restart mysql)
查询默认的用户名和密码：
sudo cat /etc/mysql/debian.cnf
# Automatically generated for Debian scripts. DO NOT TOUCH! [client] host = localhost user = debian-sys-maint password = F64nKZ233QkzL8v9 socket = /var/run/mysqld/mysqld.sock [mysql_upgrade] host = localhost user = debian-sys-maint password = F64nKZ233QkzL8v9 socket = /var/run/mysqld/mysqld.sock
备注：这样比较麻烦，无法复制密码，可以直接打开你的文件管理器，用管理员身份打开debian.cnf即可查看复制密码
利用默认账户进行登录：mysql -u debian-sys-maint -p(文件中的密码，与p之间不要有空格)
3.进入mysql修该密码
设置root账户密码：
CREATE USER 'root'@'%' IDENTIFIED with mysql_native_password BY '这里是你要设置的密码'; GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION; flush privileges;
4.退出数据库
exit
5.用自己设置好的密码登录
mysql -u root -p
输入密码,成功登录,如下.
jokul@jokul-PC:~$ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

恭喜你，同学 你成功了！
PS：推荐DEEPIN上连接数据库工具用”dbeaver-ce”
