• 备份配置文件

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

• 打开配置文件,并清空

sudo vim /etc/apt/sources.list

+粘贴上以下代码(这里采用中科大的镜像)

deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse

安装mysql

• 执行安装以下命令，此时会从服务器下载，中科院的镜像默认5.7版本

sudo apt-get install mysql-server 

• 查找安装时的账户密码信息

 sudo cat /etc/mysql/debian.cnf

• 修改mysql 密码

use mysql;
update mysql.user set authentication_string=password(‘123456‘) where user=‘root‘ and Host =‘localhost‘; 
update user set  plugin="mysql_native_password";
flush privileges;
quit;

• 修改端口执行 sudo vi /etc/mysql/my.cnf

--编辑
port = 3306
