Explanation

You can invoke mysqld manually. This is usually not done except for debugging purposes. If you invoke the server this way, error messages go to the terminal by default rather than to the mysqld_safe is a shell script that invokes mysqld. The script sets up the error log, and then launches mysqld and monitors it. If mysqld terminates abnormally, mysqld_safe restarts it. mysql.server is a shell script that invokes mysqld_safe. It's used as a wrapper around mysqld_safe for systems such as Linux and Solaris that use System V run-level directories. Typically, this script is renamed to mysql when it is installed in a run-level directory.
