Just a heads-up - when trying to use the command :
pkg install mysql55-server
I get the advisory :
pkg: No packages matching 'mysql55-server' has been found in the repositories
Executing a pkg search on MySQL nets quite a few results, most interesting of which are that the mysql server branch has been renamed. The correct one, for 5.5, is :
mysql-server-5.5.32
Might want to update the guide to reflect.
Cheers!
