Resolved: Accidentally changed ownership of all Freebsd files - mysql won't start. How to fix?

Question

FreeBSD

Accidentally did chown -R root:wheel * on all files on the server. Now mysql does not start, no errors are written to the console. I wanted to reinstall mysql but got an error too. Here is an excerpt from the end of the log:

===>  Cleaning for pkg-1.6.2
pkg-static: /var/db/pkg wrong user or group ownership (expected 0/0 versus actual 88/88)
pkg-static: /var/db/pkg wrong user or group ownership (expected 0/0 versus actual 88/88)
You are about to convert your system to pkg while you have ports/packages
installed with the old pkg_install tools.

To switch to pkg:
    1) Install ports-mgmt/pkg
       cd ports-mgmt/pkg && make UPGRADEPKG=1 install clean
    2) Convert your package database by running pkg2ng

*** Error code 1

Stop in /usr/ports/ports-mgmt/pkg.

Solution: rm /tmp/mysql.sock
and restart mysql.
