mysqld_safe is the recommended way to start a mysqld server on Unix.
mysqld_safe adds some safety features such as
restarting the server when an error occurs and
logging runtime information to an error log file

...
mysqld_safe tries to start an executable named mysqld.

...
Many of the options to mysqld_safe are the same as the options to mysqld.
