The .PID file is deleted when mysql.server start is executed

I have MySQL installed Brew install MySQL and when I run mysql.server start, I get the error ERROR! The server was stopped without updating the PID file (/usr/local/var/mysql/
After creating the PID file, I start mysql.server start and get the same error. I tried to delete the .err file, but it constantly removes my .pid file. Any ideas, what am I doing wrong?
