1、安裝Mysql

sudo apt-get install mysql-server

sudo apt-get install mysql-client

sudo apt-get install libmysqlclient-dev

2、修改root密碼

sudo more /etc/mysql/debian.cnf

用檔案裡的使用者名稱密碼登陸Mysql

use mysql

update user set plugin='mysql_native_password' where user='root';

update user set authentication_string
 
=password('123') where user='root';

flush privillege;

3、配置遠端訪問

註釋掉在/etc/MySQL/mysql.conf.d/mysqld.cnf裡面的bind-address = 127.0.0.1

連線mysql資料庫，修改user表

Grantall on *.* to 'root'@'%' identifiedby 'root使用者的密碼' withgrant option;flush privileges;
