I am trying to set the root password for MySQL in the terminal in Mac OS X Lion, and I am having issues. Every time I use the line:
/usr/local/mysql/bin/mysqladmin -u root password ****** (where ****** is the password I want to set)
I receive the error:
/usr/local/mysql/bin/mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'#'localhost' (using password: NO)'
I have not set a password previously, so I do not know why I am receiving this error.

Answer 1

Here is the procedure to reset password of root user.
1) Stop mysql (Kill mysql process or run following command)
sudo /usr/local/mysql/support-files/mysql.server stop
2) Start it in safe mode
sudo mysqld_safe --skip-grant-tables
3) Open another terminal and run the following command (Keep last terminal open)
mysql -u root
4) Run the following command with suitable new password on the mysql console
For MySQL 5.7+:
mysql > UPDATE mysql.user SET authentication_string=PASSWORD('password') WHERE User='root';
For earlier versions:
mysql > UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';
5) mysql > FLUSH PRIVILEGES;
6) Quit from both terminals and open new terminal and connect to mysql with root user and new password
mysql -uroot -p

Answer 2

Type:/usr/local/mysql/bin/mysqladmin -u root -p password
When it asks for a password, not not enter anything, just hit enter.
It will then ask you to enter new password, then confirm.
Finished.

Answer 3

for creating password first time use
mysqladmin -u root password NEWPASSWORD
updating old password use
mysqladmin -u root -p'oldpassword' password newpass

Answer 4

I'm on Yosemite, but on Maverick has the same problem.
- Fix the 2002 socket error first if you haven’t done
sudo mkdir /var/mysql
sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock
An then try
sudo /usr/local/mysql/bin/mysqladmin -u root -p password

Answer 5

That isn't how you set the password. That is how you login to mysql.
If you don't have a password set, you login using:
mysql -u root
and that will get you to the MySQL command line.
Instead of doing that just use the following to change the password.
mysqladmin -u root password NEWPASSWORD

Answer 6

cd /usr/local/mysql/bin
./mysqladmin -u root password root

Answer 7

To set your root password after installing:
Ensure MySQL is not running, stop it if you ran it.
On a Terminal do sudo mysqld_safe --skip-grant-tables to run MySQL bypassing the authentication.
Inside mysql do FLUSH PRIVILEGES;
Then reset by SET PASSWORD FOR root#'localhost' = PASSWORD('password'); where 'password' is your chosen password.
FLUSH PRIVILEGES; one more time

Answer 8

This fix it for me:
After this is going to ask you for your Super User password and then for the new password.
sudo /usr/local/mysql/bin/mysqladmin -u root -p password

Answer 9

You want to reset or set a new root password?
Steps for MySQL 5.7.5 and earlier:
Open a Terminal Window:
Stop mysql server if it is running:
sudo /usr/local/mysql/support-files/mysql.server stop
Restart it with the --skip-grant-tables option:
sudo mysqld_safe --skip-grant-tables
Open another Terminal Window:
Type:
mysql -u root
Reset root password (i.e. for localhost)
UPDATE mysql.user
SET authentication_string = PASSWORD(‘MyNewPass’), password_expired = 'N'
WHERE User = 'root' AND Host = 'localhost';
FLUSH PRIVILEGES;
Now your password for root#localhost is MyNewPass. You can change it:
Close all Terminal Windows. Open a new Terminal Window and type:
mysqladmin -u root -p'MyNewPass' password '123456'
Now your root password is 123456
You should see below warning message, you can ignore it if you are changing your root#localhost password:
mysqladmin: [Warning] Using a password on the command line interface
can be insecure. Warning: Since password will be sent to server in
plain text, use ssl connection to ensure password safety.
Check if your root password is successfully changed:
mysql -u root -p'123456' -e 'show databases;'
Output:
mysql: [Warning] Using a password on the command line interface can be
insecure.
