MacOS Mojave - brew install [email protected] - 用户'root'@'localhost'拒绝访问

Question

在MacOS Mojave上通过homebrew（即qazxsw poi）安装mysql时，看似成功的安装会打印以下说明：

brew install [email protected]

当运行

We've installed your MySQL database without a root password. To secure it run:
    mysql_secure_installation

MySQL is configured to only allow connections from localhost by default

To connect run:
    mysql -uroot

或mysql -uroot时，我收到以下错误：

mysql_secure_installation

如何登录ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) 更改mysql的密码？

Answer 1

似乎通过root标志使用“空字符串”密码解决了这个问题：

--password

或者，您可以使用mysql -uroot --password="" 手动启动mysqld：

--skip-grant-tables

最后用以下内容更改密码：

$ mysql.server --skip-grant-tables
$ mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.

Answer 2

新的brew mysql安装完成后：

1）确保mysql正在运行：brew services启动mysql

2）更改mysql密码：mysqladmin -uroot --password =“”密码'NEWPASSWORD'

3）安全mysql：mysql_secure_installation（使用新密码）
