Unable To Access Mysql With Root and No Password After New Install On Ubuntu30 Jan 2018
This bit me in the rear end again today. Had to reinstall mysql-server-5.7 for other reasons.
You just installed
mysql-server locally for your development environment on a recent version of Ubuntu (I have 17.10 artful installed). You did it with a blank password for
root user. You type
mysql -u root and you see
Access denied for user 'root'@'localhost'.
Because you chose to not have a password for the
root user, the
auth_plugin for my MySQL defaulted to
auth_socket. That means if you type
sudo mysql -u root you will get in. If you don’t, then this is NOT the fix for you.
mysql_native_password so that you can use the root user in the database.
$ sudo mysql -u root mysql> USE mysql; mysql> UPDATE user SET plugin='mysql_native_password' WHERE User='root'; mysql> FLUSH PRIVILEGES; mysql> exit; $ sudo systemctl restart mysql $ sudo systemctl status mysql
NB ALWAYS set a password for mysql-server in staging/production.
