创建用户时更正mysql语法错误 [英] Correct mysql syntax error when creating a user

问题描述

因此我收到了非常常见的ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) mysql错误.我已经尝试了论坛上的所有典型修复程序，通过mysql_safe方法登录，然后尝试重置我的root密码.但是这样做时，它会返回；

So im getting the very common ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) mysql error. I have tried all of the typical fixes on the forums, logging in via the mysql_safe method and then trying to reset my root password. However when doing so it returns with;

UPDATE user SET password=PASSWORD("PASSWORD")WHERE user="root";
Query OK, 0 rows affected (0.00 sec)
Rows matched: 0  Changed: 0  Warnings: 0

因此，因为没有行受到影响，所以我假设没有用户要实际更改.我试图创建一个用户:

So as no rows were affected I assumed there was no user to actually change. I tried to create a user:

CREATE USER 'root'@'localhost' IDENTIFIED BY 'root'
    -> GRANT ALL ON *.* TO 'root'@'localhost'
    -> flush privileges;

However this returns with 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 'GRANT ALL ON *.* TO 'root'@'localhost'

查看当前用户是什么:

mysql> SELECT user();
+--------+
| user() |
+--------+
| root@  | 
+--------+

我认为语法错误是"root"之后@之后没有任何内容的事实.我如何将这些信息编辑为root @ localhost并解决问题?

I assume the syntax error is the fact that nothing comes after the @ after "root". How can i edit this information to be root@localhost and correct the issue?

更新

在仔细阅读了mysqld文档之后，我进入了本节，它运行良好.

after carefully reading the mysqld docs i got to this section which worked perfectly.

停止mysqld并使用--skip-grant-tables选项重新启动它.这样一来，任何人都无需密码就可以使用所有特权进行连接.因为这是不安全的，所以您可能希望将--skip-grant-tables与--skip-networking结合使用，以防止远程客户端连接.

Stop mysqld and restart it with the --skip-grant-tables option. This enables anyone to connect without a password and with all privileges. Because this is insecure, you might want to use --skip-grant-tables in conjunction with --skip-networking to prevent remote clients from connecting.

使用以下命令连接到mysqld服务器:

Connect to the mysqld server with this command:

shell> mysql

在mysql客户端中发出以下语句.将密码替换为您要使用的密码.

Issue the following statements in the mysql client. Replace the password with the password that you want to use.

mysql> UPDATE mysql.user SET Password=PASSWORD('MyNewPass')
    ->                   WHERE User='root';
mysql> FLUSH PRIVILEGES;

FLUSH语句告诉服务器将授权表重新加载到内存中，以便它注意到密码更改.

The FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change.

推荐答案

它应该是三个sql语句，

it should be three sql statements,

CREATE USER 'root'@'localhost' IDENTIFIED BY PASSWORD 'root';
GRANT ALL ON *.* TO 'root'@'localhost';
FLUSH PRIVILEGES;

• 创建用户
• CREATE USER
