I think the root account has lost all privileges,or this root account has been replaced by ''#'localhost'
I use windows 7.
I login in the mysql with root account
C:\Users\Administrator>mysql -u root -p
Enter password: ******
when type use mysql,i got this
mysql> use mysql
ERROR 1044 (42000): Access denied for user ''#'localhost' to database 'mysql'
then i type show databases;,there are only two

命令成功完成。
C:\Users\Administrator>mysql -u root -p admin
Enter password: ******
ERROR 1044 (42000): Access denied for user ''#'localhost' to database 'admin'

Please can you help me
Make sure you set your user privileges right
Like -host localhost -user root and -pass {your pass word}
GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' IDENTIFIED BY PASSWORD;. Set a user privilege to a particular user like people and then follow the example grant all on people.*to 'root'#'localhost' identified by 'PASSWORD';
I have started MySQL in safe mode then assigned appropriate privileges( Referenced from here)
Stop MySQL service
Run mysqld_safe --skip-grant-tables &
Type MySQL -u root -p and press enter.
Enter your password
At the MySQL command line enter: use mysql;
After this, I have updated the privileges in mysql.user table for appropriate host and user. Flush privileges;
Now this works for me
you can also refer the answer for update privilages
now, I can login the mysql with mysql -uroot -p, then I input my password.
Then I try to do this.
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
+--------------------+
But when I create database, i get an error:
mysql> CREATE DATABASE newdb;
ERROR 1044 (42000): Access denied for user 'root'#'localhost' to database 'newdb'
this is my grants:
mysql> show grants;
+------------------------------------------+
| Grants for root#localhost |
+------------------------------------------+
| GRANT USAGE ON *.* TO 'root'#'localhost' |
+------------------------------------------+
on the terminal with MacOSX. Thanks for any help.
From the docs, GRANT USAGE is a:
Synonym for “no privileges”
Leaving aside the point that this privilege has a confusing name, I'm not sure how/why you have such limited privileges for root, anyway.
What you want for root is GRANT ALL. Even better, leave root as-is and create a different superuser with local-only access to replace root. But do note that, in general, you want to give users only the bare minimum privileges necessary for whatever they need to do.
I have strange error. I am logged in local Mysql as root via command line. After creating database:
create database some_db;
Then giving privileges to some user:
grant all privileges on some_db.* to some_user#'localhost' identified by 'password';
This is giving error:
ERROR 1044 (42000): Access denied for user 'root'#'localhost' to database 'some_db'
The permissions for the root(show grants;) shows:
GRANT ALL PRIVILEGES ON *.* TO 'root'#'localhost' IDENTIFIED BY PASSWORD '*8919C53DC7A4DFBF3F8584382E96463583EB7FDA'
I am also making sure i am logged in as root:
select current_user();
And this confirms that i am logged in as 'root'#'localhost'
I have created database and assigned user multiple times and never had an issue. Why i am unable assign user to the database created by root while logged in as root?
p.s. from other posts, i am thinking the issue may be caused due to some strange users
select host, user from mysql.user;
Some users that i have not added but does show up:
MY_COMPuTER_name.local | ''
MY_COMPuTER_name.local | root
I tried to delete these users
drop user 'root'#'MY_COMPuTER_name.local';
drop user ''#'MY_COMPuTER_name.local';
However, while it states query run successful, the users are not dropped even after flush privileges. Why i am unable delete users? Any help is much appricated
First, Identify the user you are logged in as:
select user();
select current_user();
The result for the first command is what you attempted to login as, the second is what you actually connected as. Confirm that you are logged in as root#localhost in mysql.
Grant_priv to root#localhost. Here is how you can check.
mysql> SELECT host,user,password,Grant_priv,Super_priv FROM mysql.user;
+-----------+------------------+-------------------------------------------+------------+------------+
| host | user | password | Grant_priv | Super_priv |
+-----------+------------------+-------------------------------------------+------------+------------+
| localhost | root | ***************************************** | N | Y |
| localhost | debian-sys-maint | ***************************************** | Y | Y |
| localhost | staging | ***************************************** | N | N |
+-----------+------------------+-------------------------------------------+------------+------------+
You can see that the Grant_priv is set to N for root#localhost. This needs to be Y. Below is how to fixed this:
UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='root';
FLUSH PRIVILEGES;
GRANT ALL ON *.* TO 'root'#'localhost';
I logged back in, it was fine.
The reason i could not delete some of the users via 'drop' statement was that there is a bug in Mysql http://bugs.mysql.com/bug.php?id=62255 with hostname containing upper case letters. The solution was running following query:
DELETE FROM mysql.user where host='Some_Host_With_UpperCase_Letters';
I am still trying to figure the other issue where the root user with all permissions are unable to grant privileges to new user for particular database
If you get an error 1044 (42000) when you try to run SQL commands in MySQL (which installed along XAMPP server) cmd prompt, then here's the solution:
Close your MySQL command prompt.
Open your cmd prompt (from Start menu -> run -> cmd) which will show: C:\Users\User>_
Go to MySQL.exe by Typing the following commands:
C:\Users\User>cd\
C:\>cd xampp
C:\xampp>cd mysql
C:\xxampp\mysql>cd bin
C:\xampp\mysql\bin>mysql -u root
Now try creating a new database by typing:
mysql> create database employee;
if it shows:
Query OK, 1 row affected (0.00 sec)
mysql>
Then congrats ! You are good to go...
Try to comment string "sql-mode=..." in file my.cnf and than restart mysql.
I'm setting a MySQL server (actually a Percona server, but that shouldn't matter) and I'm setting a password to the root user. At the end, I have this:
mysql> select host, user, password from user;
+-----------+------------------+-------------------------------------------+
| host | user | password |
+-----------+------------------+-------------------------------------------+
| localhost | root | *huge string here, no kidding |
| localhost | debian-sys-maint | *another huge string here |
+-----------+------------------+-------------------------------------------+
2 rows in set (0.00 sec)
I thought this should not allow the root user to connect without a password. However, if I go to the command line, I can connect with mysql -u root or just mysql. If I do mysql -u root -p and hit enter for the password, then I get ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: NO).
Could anyone explain to me how to make sure a user can only connect with a password?
Edit: if relevant, I set the password with SET PASSWORD FOR 'root'#'localhost' = PASSWORD('somethinghere');
Edit: output of show grants, it indicates I used a password to login but I did not.
mysql> show grants;
+----------------------------------------------------------------------------------------------------------------------------------------+
| Grants for root#localhost |
+----------------------------------------------------------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'#'localhost' IDENTIFIED BY PASSWORD '*huge string here, no kidding' WITH GRANT OPTION |
| GRANT PROXY ON ''#'' TO 'root'#'localhost' WITH GRANT OPTION |
+----------------------------------------------------------------------------------------------------------------------------------------+

Facepalm. It turned out there was a .my.cnf on /root with username and password, and so it was possible to login only with mysql when using the root account (that's what I was using). It was created by a Chef recipe (percona was installed via Chef) and I wasn't aware of it.
The hint was to look at the output of show grants. Even though I entered no password it still said I entered one, so there must be one somewhere!
When I attempt to create a database this happens:
mysql> CREATE DATABASE testing;
ERROR 1044 (42000): Access denied for user ''#'localhost' to database 'testing'
When I run select user(); this happens:
mysql> select user();
+-------------+
| user() |
+-------------+
| X#localhost |
+-------------+
1 row in set (0.00 sec)
When I attempt to login as root this happens:
> mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)
I have tried over 15 different GRANT and FLUSH PRIVILEGES methods. Including putting the commands in a text file and doing it that way. I am on Mountain Lion using mySQL Server and Sequal Pro for managing the database.
Sequal Pro tells me that I cannot add a database as well. I have attempted to completely reinstall mySQL and that didn't seem to work either. I am new to mySQL and just need to start creating a database, I am going through the Django Book tutorials before I start on a project.
The only way I am able to access mysql is if i use
mysql -u X -p
However, that leads back to my permission errors up top.
