这个错误提示表明你连接 MySQL 数据库时使用的用户名为 'root',但是数据库拒绝了这个用户的连接请求,可能是由于密码错误或者没有授权等原因导致的。
你可以检查一下以下几点:
1. 确认 MySQL 服务已经启动,并且监听的端口号是正确的;
2. 确认连接 MySQL 数据库时使用的用户名和密码是否正确;
3. 确认该用户是否被授予权限访问该数据库;
4. 确认该用户是否被授予权限从本地主机访问该数据库。
如果以上都没有问题,那么你可以尝试使用命令行工具连接 MySQL 数据库,看看是否能够成功连接。如果连接成功,那么就说明问题出现在你的代码里,你需要检查一下连接数据库的代码是否有问题。如果连接失败,那么就需要进一步检查 MySQL 数据库的配置和状态。
