Cannot get it started on CentOS 7

After years w/vanilla MySQL we’re working to jump to Percona. So we did vanilla install. Starting it up but it errors out… But wait, there’s a process running! Oh good! Oh but wait, I can’t login (see last red circle). How do I log in?

Going to uninstall and try again unless you have other thoughts?

Ping! Any thoughts?

BTW, called the tech support line, got a really nice guy in Philippines but don’t have support contract, yet… Hoping these boards proved L1-type tech support… Plan to purchase support contract if these boards help with the basics…

Hello? Mic check…

Bummed this forums aren’t more active…

Removed everything, reinstalled, works fine.
