ER_HOST_NOT_PRIVILEGED: Host '172.19.0.3' is not allowed to connect to this MySQL server

[UpCoder]

I write a docker-compose that contains a website and a mysql
in my docker-compost, ,there write as follow:

version: '2.0'
services:
    website: 
        build: 
            context: /Users/Liang/Desktop/dockercompose/website/
            dockerfile: ./Dockerfile
        ports: 
            - "3001:3001" 
        links:
            - website_mysql:website_mysql
        depends_on:
            - website_mysql
        container_name: "website"
    website_mysql:
        build: 
            context: /Users/Liang/Desktop/dockercompose/mysql/
            dockerfile: ./Dockerfile
        container_name: "website_mysql"
        expose:
            - "3306"
        environment:
            - MYSQL_ROOT_PASSWORD="xA123456"

when I exec docker-compose up
there is a error when execute "npm start" in my website container. the error is a title.
maybe it caused by the remote access authority, but i don't know how to fix it
please help me, thank you very much

Is your node container configured to connect via root@website_mysql using xA123456 as the password?

It's probably also worth giving docker-library/postgres#203 (comment) a read through (good info about databases, volumes, and docker-compose in general, not specific to postgres).

It works now.but i forget i how to fix it😂😂 this is my now dockerfile as follow
mysql dockerfile:

FROM mysql:5.7
MAINTAINER [email protected]
#mysql config
ARG password=xA123456

ADD ./exec.sql /exec.sql
ADD ./exec.sql /docker-entrypoint-initdb.d/exec.sql
ADD ./mysqld.cnf /etc/mysql/mysql.conf.d/mysqld.cnf
ENV MYSQL_ROOT_PASSWORD $password

EXPOSE 3306
