Error: Cannot install mysql because conflicting formulae are installed.
mariadb: because mysql, mariadb, and percona install the same binaries.
Please `brew unlink mariadb` before continuing.
Unlinking removes a formula's symlinks from /usr/local. You can
link the formula again after the install finishes. You can --force this
install, but the build may fail or cause obscure side-effects in the
resulting software.
