MySQL 5.6 Reference Manual Including MySQL NDB Cluster 7.3-7.4 Reference Guide
If you get the following error, it means that when
mysqld was started or when it reloaded the
grant tables, it found an account in the
user
table that had an invalid password.
Found wrong password for user
'
some_user
'@'some_host
';
ignoring user
As a result, the account is simply ignored by the permission system.
The following list indicates possible causes of and fixes for this problem:
You may be running a new version of
mysqld with an old
user
table. Check whether the
Password
column of that table is
shorter than 16 characters. If so, correct this condition
by running mysql_upgrade.
The account has an old password (eight characters long).
Update the account in the user
table to
have a new password.
You have specified a password in the
user
table without using the
PASSWORD()
function. Use
mysql to update the account in the
user
table with a new password, making
sure to use the PASSWORD()
function:
mysql>UPDATE user SET Password=PASSWORD('
->new_password
')WHERE User='
some_user
' AND Host='some_host
';
