How to find out the MySQL root password

Question

I cannot figure out my MySQL root password; how can I find this out? Is there any file where this password is stored?

I am following this link but I do not have dir

Answer 1

In your "hostname".err file inside the data folder MySQL works on, try to look for a string that starts with:

"A temporary password is generated for roor@localhost "

you can use

less /mysql/data/dir/hostname.err 

then slash command followed by the string you wish to look for

/"A temporary password"

Then press n, to go to the Next result.

Answer 2

You cannot find it. It is stored in a database, which you need the root password to access, and even if you did get access somehow, it is hashed with a one-way hash. You can reset it: http://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html

Answer 3

Answers provided here did not seem to work for me, the trick turned out to be: ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'test';

Answer 5

The procedure changes depending the version of MySql. Follow the procedure exactly as described for your version:

• HINTS - Read before the instructions page for your version of MySql*

• In step 5: Instead of run CMD, create a shortcut on your desktop calling CDM.exe. Then right-click on the shortcut and select "Execute as Administrator".

• In step 6: Skip the first proposed version of the command and execute the second one, the one with the --defaults-file parameter

• Once you execute the command, if everything is ok, the CMD window remains open and the command of step 6 continues executing. Simply close the window (click 'x'), and then force close MySQl from the Task Manager.

• Delete the file with the SQL commands, and start again MySQL. The password must be changed now.

5.0 http://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html

5.1 http://dev.mysql.com/doc/refman/5.1/en/resetting-permissions.html

... just change the version in the link (5.5, 5.6, 5.7)

Answer 6

You can't view the hashed password; the only thing you can do is reset it!

Stop MySQL:

sudo service mysql stop

or

$ sudo /usr/local/mysql/support-files/mysql.server stop

Start it in safe mode:

$ sudo mysqld_safe --skip-grant-tables

(above line is the whole command)

This will be an ongoing command until the process is finished so open another shell/terminal window, log in without a password:

$ mysql -u root

mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';

MySQL 5.7 and over:

mysql> use mysql; 
mysql> update user set authentication_string=password('password') where user='root'; 

Start MySQL:

sudo mysql start

or

sudo /usr/local/mysql/support-files/mysql.server start

Your new password is 'password'.
