Antes de eu estragar alguma coisa, quando eu faço login usando $ mysql -u root -p
, e mostro bancos de dados:
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| game_data |
| test |
+--------------------+
Depois tentei criar um novo utilizador e reparei que algo estava errado com os PRIVILEGIADOS.
Então eu deletei os novos usuários, e acho que removi o 'root' e 'Admin' acidentalmente.
Então eu tento criar 'root' mais uma vez, mas ter o Access negado erro ao fazer conceder todos os privilégios.
mysql> CREATE USER 'root'@'localhost' IDENTIFIED BY 'password';
mysql> grant all privileges on *.* to 'root'@'localhost' identified by 'password' with grant option;
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
Se eu entrar no MySQL novamente utilizando `$ mysql -u root -p', e mostrar bases de dados,
+--------------------+
| Database |
+--------------------+
| information_schema |
+--------------------+
Todas as outras bases de dados desapareceram.
Como faço para consertar o MySQL agora?
Não consigo encontrar o banco de dados 'mysql', não consigo criar banco de dados, criar usuário, qualquer coisa que eu tente fazer terá um erro.
ERROR 1045 (28000): Acesso negado para usuário 'root'@'localhost' (usando senha: SIM).
Devo reinstalar o MySQL usando o MacPorts? Se reinstalar, vou perder a base de dados game_data
, certo?
Siga os passos abaixo.
Inicie a instância do servidor MySQL ou daemon com a opção `--skip-grant-tables' (configuração de segurança).
$ mysqld -- tabelas de classificação
Executar estas declarações.
$ mysql -u root mysql
$mysql> UPDATE user SET Password=PASSWORD('my_password') where USER='root';
$mysql> FLUSH PRIVILEGES;
Se você se deparar com o campo desconhecido Erro de senha acima de uso:
update user set authentication_string=password('my_password') where user='root';
Finalmente, reinicie a instância/daemon sem a opção `--skip-grant-tables'.
$ /etc/init.d/mysql restart
Agora você deve ser capaz de se conectar com a sua nova senha.
$ mysql -u root -p
Digite a senha: my_password
.

By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y
Success.
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y
Success.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y
Success.
All done!
