strapi默认数据库sqlite更改为mysql数据库

一、本地安装mysql数据库

终端输入如下命令
1、PATH="$PATH":/usr/local/mysql/bin
2、mysql -u root -p
3、create database 数据库名称 default character set utf8 collate utf8_general_ci; [//]: # 创建数据库
4、drop database <数据库名>; 删除数据库

二、更改了strapi项目中config/database.js文件

module.exports = ({ env }) => ({
  defaultConnection: 'default',
  connections: {
    default: {
      connector: 'bookshelf',
      settings: {
        // client: 'sqlite',
        // filename: env('DATABASE_FILENAME', '.tmp/data.db'),
        client: 'mysql',
        host: 'localhost',
        port:  3306,
        database: 'meishu',
        username: 'root',
        password: '123456',
      },
      options: {
        useNullAsDefault: true,
      },
    },
  },
});

完成以上步骤之后npm run develop运行strapi项目，发现报错，报错内容如下：

根据报错信息了解到 mysql8.0以上加密方式，Node还不支持

ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘123456’;(输入如下命令重启mysql，mysql命令后跟冒号)
这样就可以解决以上问题了
