How to reset the root password in MySQL 8.0.11?(如何在 MySQL 8.0.11 中重置 root 密码?)

问题描述

我实际上丢失了我的 root 密码，我需要更改它.我遵循以下步骤:

I have actually lost my root password and I need to change it. I follow these steps :

• 第 1 步:停止 MySQL 服务器进程.

• Step # 1: Stop the MySQL server process.

第 2 步:使用以下命令启动 MySQL (mysqld) 服务器/守护进程--skip-grant-tables 选项，这样它就不会提示输入密码.

Step # 2: Start the MySQL (mysqld) server/daemon process with the --skip-grant-tables option so that it will not prompt for a password.

第 3 步:以 root 用户身份连接到 MySQL 服务器.

Step # 3: Connect to the MySQL server as the root user.

that we can found on these website : https://www.howtoforge.com/setting-changing-resetting-mysql-root-passwords#recover-mysql-root-password

mysql> use mysql;
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD("TOOR");
mysql> flush privileges;
mysql> quit

第一个错误，所以我尝试了:

First error, so I tried :

mysql> use mysql;
mysql> update user set password=PASSWORD("TOOR") where User='root';
mysql> flush privileges;
mysql> quit

总是同样的错误说:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near '("TOO
R") WHERE User='root'' at line 1

我该如何解决这个问题?

How can I resolve this?

推荐答案

as 这里 说:

这个函数在 MySQL 8.0.11 中被移除了

This function was removed in MySQL 8.0.11

1.如果您处于跳过授权表模式
在 mysqld_safe 中:

1.if you in skip-grant-tables mode
in mysqld_safe:

UPDATE mysql.user SET authentication_string=null WHERE User='root';
FLUSH PRIVILEGES;
exit;

然后，在终端:

mysql -u root

在mysql中:

ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';

2.不在跳过授权表模式
就在mysql中:

2.not in skip-grant-tables mode
just in mysql:

ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';
