Question

在MacOS Mojave上通过自制程序（即brew install mysql@5.7）安装mysql时，似乎成功安装会显示以下说明：

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

运行mysql -uroot或mysql_secure_installation时，出现以下错误：

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

如何登录mysql来更改root的密码？

Answer 1

似乎通过--password标志使用“空字符串”密码可以解决此问题：

mysql -uroot --password=""

或者，您可以以mysqld手动开始--skip-grant-tables：

$ mysql.server --skip-grant-tables
$ mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

$

最后使用以下命令更改密码：

mysqladmin -uroot --password="" password NEW_PASSWORD

Answer 2

在安装新的brew mysql之后：

1）确保mysql正在运行：brew服务启动mysql

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

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

Answer 3

我认为所有在安装后运行mysql_secure_installation命令的人都会遇到此麻烦。

我们需要附加用户名和密码参数，以便对此进行思考：

mysql_secure_installation -u root --password=""

MacOS Mojave-brew install mysql@5.7-用户'root'@'localhost'的访问被拒绝
