MySQL password issues (mac OS X Lion)
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
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
