Question

I'm using Sequelize version 4.3.0 on nodejs(v6.11.0) application having Mariadb (mysql Ver 15.1 Distrib 10.0.29-MariaDB, for debian-linux-gnu (i686) using readline 5.2 ) on Ubuntu 16.04. when application starts and calls function: Sequelize.sync(); Then sequelize connection manager throws following error:

Unhandled rejection SequelizeConnectionError: Client does not support authentication protocol requested by server; consider upgrading MariaDB client

I updated mariadb-server and mariadb-client but the problem already exists!

Anyone can help me to solve this problem ?

Answer 1

我找到了答案：

登录mysql命令行并编写以下命令：

use mysql;

update user set authentication_string=password(''),plugin='mysql_native_password' where user='root';

Answer 2

在我的情况下，我需要键入以下三行：

use mysql;
update user set authentication_string=password('new_root_password'), plugin='mysql_native_password' where user='root';
flush privileges;

Answer 3

如果您使用的是更高版本的mysql，则无需使用密码功能。相反，您可以将其编写如下

use mysql;

update user set authentication_string='new_root_password', plugin='mysql_native_password' where user='root';

flush privileges;
