背景： 最近公司发了新MAC， 芯片是M1的， 需要重新装一些东西 项目使用了node，需要连接本地数据库， 考虑用docker装数据库

docker 中下载 mysql

docker pull mysql
// M1会报错， 执行如下命令
docker run --platform linux/x86_64 mysql

启动

docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=12345678 -d mysql

进入容器

docker exec -it mysql bash

登录mysql

mysql -u root -p
ALTER USER 'root'@'localhost' IDENTIFIED BY '12345678';

踩坑记录

1. 使用nodejs连接数据库时，因为mysql客户端不支持认证协议引发的“ER_NOT_SUPPORTED_AUTH_MODE”问题

C:\Users\mysql-test>node app.js
    C:\Users\mysql-test\node_modules\mysql\lib\protocol\Parse
    r.js:80
            throw err; // Rethrow non-MySQL errors
            ^

解决方案

进入mysql服务器，运行以下命令

 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
 

如果不生效， 去掉@'localhost'试试

2. 使用navicat等连接数据库时报错

# Access denied for user ‘’@’172.17.0.1'(using password: YES)

解决方案

进入mysql服务器，运行以下命令

mysql> CREATE USER 'root'@'172.17.0.1' IDENTIFIED BY 'password'; // password：进入数据库密码
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'172.17.0.1' WITH GRANT OPTION;
mysql> flush privileges; // 使修改立即生效
mysql> exit
