I've just installed a copy of MySQL 5.7 for testing, and I love the fact that it now only creates a single root account, and puts the password into a file called .mysql_secret.

There's just one problem. Where can I find the above mentioned file. On Linux it is apparently found in $HOME, but my test DB is on Windows.

I tried various places including %USERPROFILE% but I just can't find it anywhere!!

Can anyone please tell me where to find this file? As otherwise my testing will be over before it has begun.

My blind guess would be to look in %APPDATA%\MySQL on your system as follows:

cd MySQL
dir .my_secret

For those who use the MySQL no-install Zip File (such as myself), you will not see one.

If .my_secret is not on your Windows servers, I have an alternative. You could start up mysqld manually with skip-grant-tables, set the password

net stop mysql
cd "C:\Program Files (x86)\MySQL\MySQL 5.7\bin"
start mysqld --skip-grant-tables
mysql -ANe"update mysql.user set authentication_string=PASSWORD('mynewpassword') where user='root'"
mysqladmin shutdown
net start mysql
mysql -uroot -p
Enter password: (enter the password 'mynewpassword' and hit <Enter>)

Give it a Try !!!

  • Cheers, that worked exactly as required. It turns out though, (after spending all last night reading the MySQL documents in detail) that, as far as I can tell, the .mysql_secret only applies to Linux. On Windows, it is still insecure and creates a root user with no password. I was inadvertently seeing a MySQL Bug (#75656) which is why I couldn't connect.

The .mysql_secret file is only used by mysql_install_db (which is deprecated).

The new way to bootstrap a server (mysqld --initialize) writes the randomly generated password to the error log.


Can you check your my.ini file? (inside MySQL folder)

There you should find something like:

  • Cheers. I always take the username / passwords out of the ini file for security reasons. I put them back in under [mysqladmin] but it made no difference.
