After I Install mysql on my droplet, As soon as I exit; from mysql I get ERROR 1045 Access denied
ERROR 1045 (28000): Access denied for user ‘root’@'localhost’ (using password: NO)
I followed the instructions in stage 2 of https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-ubuntu-18-04#step-2-%E2%80%94-installing-mysql
I have tries removing and purging and re-installing in case I made a mistake. If i did I made the same mistake again. What might it be?
