Ignore users in MySQL

MySQL databaseDuring OperationIgnore userThe problem will cause a lot of inconvenience to the MySQL database and affect the work of the MySQL database. In the following article, I will introduce you to solve the problem of ignoring users and hope to help you.

If the following error occurs, an account with an invalid password is found in the User table when mysqld is started or the authorization table is reloaded.

User 'some _ user' @ 'some _ host' Password error found: Ignore user.

As a result, the license system simply ignores the account.

The following describes possible causes and corrective measures:

1. Maybe you are planning to use the old User table to run the new version of mysqld. Run mysqlshow mysql user to check whether the Password column is less than 16 characters. This method can be used to check the problem. If the result is correct, run the script/add_long_password to correct the problem.

2. The account has an old password (8 characters long) and does not use the "-- old-protocol" option to start mysqld. Update the account in the User table to have a new password, or use the "-- old-protocol" option to restart mysqld.

3. The PASSWORD is not specified using the PASSWORD () function in the User table. To use mysql to update an account in the User table with a new PASSWORD, use the PASSWORD () function:

Reference content is as follows:
4.

Mysql> update user SET Password = PASSWORD ('newpwd ')

5.

-> Where User = 'some _ user' AND Host = 'some _ host ';
