sudo apt-get install mysql-server
sudo apt-get install mysql-client
sudo apt-get install libmysqlclient-dev

use mysql
update user set plugin='mysql_native_password' where user='root';
update user set authentication_string=password('123456') where user='root';
flush privilleges;

注释掉在/etc/mysql/mysql.conf.d/mysqld.cnf里面的bind-address = 127.0.0.1
连接mysql数据库,修改user表
grant all on *.* to 'root'@'%' identified by '123456' with grant option;
flush privileges;
