MacOSX homebrew mysql root password

Question

For some reason MySQL stopped giving access for root. Uninstalled and reinstalled with Homebrew. Fresh install, fresh tables but when I enter

mysql -u root -         


        

Answer 1

None of these worked for me. I think i already had mysql somewhere on my computer so a password was set there or something. After spending hours trying every solution out there this is what worked for me:

$ brew services stop mysql
$ pkill mysqld
$ rm -rf /usr/local/var/mysql/ # NOTE: this will delete your existing database!!!
$ brew postinstall mysql
$ brew services restart mysql
$ mysql -uroot

Answer 2

Try with sudo to avoid the "Access denied" error:

sudo $(brew --prefix mariadb)/bin/mysqladmin -u root password NEWPASS

Answer 3

This worked for me for MAC https://flipdazed.github.io/blog/osx%20maintenance/set-up-mysql-osx

Start mysql by running

brew services start mysql

Run the installation script

mysql_secure_installation

You will be asked to set up a setup VALIDATE PASSWORD plugin. Enter y to do this.

Select the required password validation (Doesn’t really matter if it is just you using the database)

Now select y for all the remaining options: Remove anon. users; disallow remote root logins; remove test database; reload privileges tables. Now you should receive a message of

All done!

Answer 4

Use init file to start mysql to change the root password.

brew services stop mysql
pkill mysqld
echo "ALTER USER 'root'@'localhost' IDENTIFIED BY 'newRootPass';" > /tmp/mysql-init
$(brew --prefix mysql)/bin/mysqld --init-file=/tmp/mysql-init

Your root password is now changed. Make sure to shutdown server properly to save password change. In new terminal window execute

mysqladmin -u root -p shutdown

and enter your new pass.

Start your service and remove the init file

brew services start mysql
rm /tmp/mysql-init

Tested on mysql version 8.0.19

Answer 5

This worked for me:

sudo mysql -u root

Answer 6

If you run

brew install mariadb
...
brew services start mariadb
==> Successfully started `mariadb` (label: homebrew.mxcl.mariadb)

 $(brew --prefix mariadb)/bin/mysqladmin -u root password newpass
/usr/local/opt/mariadb/bin/mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost''

also login with root account fails:

mariadb -u root
ERROR 1698 (28000): Access denied for user 'root'@'localhost'

then default admin user is created same name as your MacOS account username, e.g. johnsmit.

To login as root, issue:

mariadb -u johnsmit
