I had problem with connection to database in my Rails application, so reinstalled everything according to this tutorial , and it doesn't help.我在 Rails 应用程序中连接到数据库时遇到问题，因此根据本教程重新安装了所有内容，但没有帮助。

Now when I'm running the installation of MySql Server it says:现在，当我运行 MySql Server 的安装时，它说：

error 1045 Access denied for 'root@localhost'(using password NO)错误 1045 拒绝访问“root@localhost”（使用密码 NO）

When I was reconfiguring leaved the field old password empty.当我重新配置时，将旧密码字段留空。 How I can solve this ?我该如何解决这个问题？ Here is my log:这是我的日志：

Can't connect to MySQL server on 'localhost' (10061)无法连接到“本地主机”上的 MySQL 服务器 (10061)

You mentioned that you left your password empty when you installed MySQL? 您提到您在安装MySQL时将密码留空了吗？ But your Rails seems to be trying to connect with the password 'root'. 但是您的Rails似乎正在尝试使用密码“ root”进行连接。 Which is it? 哪有 If your MySQL has a password, you need to use it to connect, and if it doesn't, you mustn't send one. 如果您的MySQL有密码，则需要使用它进行连接；如果没有密码，则不能发送密码。
