I need help. I'm new to linux but when I have to restart httpd I have to su as root

su root /etc/init.d/httpd restart

If I don't I get a "Command not Found" error message. I also tried using this command " service httpd restart" and pretty much get the same message.

I am log in as root and have root privileges to my linux machine.
Please provide a very descriptive answer to my question.

Thanks a bunch.

I guess I have to correct myself here. I'm already logged in as root so I shouldn't do su or sudo root to restart my apache. But unless I su or sudo root : su root /etc/init.d/httpd restart I'm getting this error message :
env: /etc/init.d/cmsd: No such file or directory

What do I need to change or what should I do so I only have to do /etc/init.d/http restart or do service httpd restart without having to enter su or sudo root.

Thanks again.

What is your question? You want to restart httpd without being root? You can do that with sudo.
