follow the guide I posted the link to (for the mysql part only if you prefeer).
reading the guide substitute mysql paths (ex. /usr/bin/mysql) adding a "local" (ex. /usr/local/bin/mysql) if you built mysql from source (server configuration file my.cnf should probably have to be in /usr/local/etc/ for the same reason, as data dir, I think)
but It's better for you to get the official package, because it has /etc/rc.d/rc.mysql file that is useful to start stop the service: you can have a look at that file (you have to edit if you want to use it because it will have the same path problem as above) if you want to have clear how mysql is started/stopped (because your problem, I think, it's that mysql is not started).
