The mysqld_safe script is just a nanny/startup script that starts the
mysqld (Mysql server) and make sure that this process is running. If
mysqld dies or is killed mysqld_safe will restart that process. By
using the mysqld executable directly you get more output to the screen
that should be helpf

After thinking about this more do you have SELinux running? I have
seen that to be an issue in the past where the mysqld process is
denied access to its .sock file.
