deepin v20 换源和安装mysql
由于deepin v20不能直接安装mysql所以先进行换源，更换成阿里源，这样以后速度可以更快
修改文件 sudo vim /etc/apt/sources.list
#删除内容，并添加以下内容： ## Generated by deepin-installer deb [by-hash=force] https://mirrors.aliyun.com/deepin/ panda main contrib non-free
执行sudo apt-get update
执行sudo apt-get upgrade命令。
安装mysql
1.执行安装mysql的语句
sudo apt-get install mysql-server mysql-client
2.查看可登陆账户并查看密码
3.获取到了登陆mysql的账户密码
lin@lin-PC:~$ mysql -udebian-sys-maint -pjSaNFiRzjlDAxiRN mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.21-1 (Debian) Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql>
4.之后依次进入mysql数据库，修改root密码，刷新缓存。之后就可以exit退出使用root账户登录了：
use mysql;
update user set plugin="mysql_native_password",authentication_string=password('新密码') where user="root";
FLUSH PRIVILEGES;5.使用修改后的帐号密码登陆
mysql -uroot -p000000
