unknown variable after upgrading from mySQL 5.7 to 8 After upgrading from mySQL 5.7 to 8.0 on freebsd, I keep getting the follow error, which prevents mysql to start:
[ERROR] [MY-000067] [Server] unknown variable 'innodb_large_prefix=true'.

The thing is that setting is not on my my.cnf file. I understand it is deprecated on mySQL 8, but it is not on my configuration.
Is there a way to fix it?
Best,
Francis
Found it. Apparently there was a naughty my.cnf file under /usr/local, where the variable was. Problem fixed by commenting it.
