我刚刚在CentOS 7上安装了MySQL 5.7，并且配置了root密码

mylocalhost上的MySQL登录成功，如下所示

[root@test]# mysql -u root -p
Enter password:

密码正确，是新安装的MySQL。我尝试了mysqld_safe——跳过授权表来删除我的密码，它在没有密码的情况下工作，但sql脚本无法运行。因此，出于安全目的，需要进行密码配置

phpmyadmin可以使用相同的MySQL ID和PW访问

这会是web应用程序的问题吗？（但我对此表示怀疑，因为这是一个初始设置阶段）还是我可以在MySQL方面做些什么

谢谢，

尝试重新安装mysql并添加另一个用户，例如

创建由“123”标识的用户“webuser”@“localhost”

@Mantykora7谢谢您的评论。然而，我已经重新安装了三次，它必须是“根”。我假设这个错误消息不应该说“使用密码：否”。应该是是的，因为我输入了密码。这是一台虚拟机？@Mantykora7是的，它在公共云上。Selinux和防火墙都已关闭。您可以安装其他软件进行测试吗？例如ubuntu服务器。你试过sudo su然后>mysql吗？
