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
usertable. You can check this by executing mysqlshow mysql user to see whether thePasswordcolumn is shorter than 16 characters. If so, you can correct this condition by running thescripts/add_long_passwordscript.The account has an old password (eight characters long) and you didn't start mysqld with the
--old-protocoloption. Update the account in theusertable to have a new password or restart mysqld with the--old-protocoloption.-
You have specified a password in the
usertable without using thePASSWORD()function. Use mysql to update the account in theusertable with a new password, making sure to use thePASSWORD()function:mysql>
UPDATE user SET Password=PASSWORD('->newpwd')WHERE User='some_user' AND Host='some_host';
