After installing MySQL 8, it started the server automatically and when I opened up MySQL Workbench, my tables were gone.
It says in the doc to start the server like so after installing it:
mysqld_safe --user=mysql --datadir=/path/to/existing-datadir &
However, I did not take note of the datadir path of my previous installation and as I said, the server automatically started once the installation was done, so I could not run this command.
How can I run the mysqld_safe and specify my old data? Where is my old data?
