Can't restart mysql local server -


yesterday, local sql server crashed, , after trying restarting it, had typical error showing me permission problem. trying fix it, made kinda worse. still have permission problem, don't know how fix it.

that's after mysql restart:

sudo chown -r $(whoami) /usr/local/mysql-5.6.22-osx10.8-x86_64/data

the mysql folder missing permissions.
