deepin v20安装mysql

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

1. 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

2.执行sudo apt-get update
3.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.

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
