Problem with making server

[LittleKing 1]

   When i type the commands: 

/usr/local/etc/rc.d/mysql-server stop

mysqld_safe --skip-grant-tables &

mysql -u root

use mysql;

update user set password=PASSWORD("NEW_PASS_HERE") where User='root';

flush privileges;

quit

As watched in tutorials they should work but when i use them i receive and error Command not found 

And when i use 

/usr/local/etc/rc.d/mysql-server start

i receive and error -- Warning failed to start mysql 

 

Can anyone help me?
