I am trying to run this command from WSGI script

 service httpd restart

The problem is this command can only be run by root
and apache uses the www-data user.

it has been said the solution is to use a

Deamon Process

i suppose the idea is to send the command to a file
that will be executed by a script that is considered "root" user..

its difficult to understand why they would call this a Deamon Process
and try to scare me.

Perhaps it should have been called : proxy process

when i got the idea that this was a proxy process..

i thought about adding a line to

 /var/spool/cron/root

that way the cron would execute the command for me.

but of course this means i have to get the system time
and then add 1 second to it and then add it to that line

so cron would execute the command for me as root

but my script demands an output instantly.

so i suppose i need to create a DEAMON PROCESS
that works like the cron.

in other words it is a bash file that will execute the command in a plain file..

but will this DEAMON PROCESS be running a while command 24/7 every second ?

would that not waste resources ?

it only needs to activate itself to check for a command to execute
when there is a command to be executed.

i mean in PHP and other programming languages.. running a

 while

statement when there is nothing to be executed could waste
resources of the server..

so why should a deamon process constantly be listening for anything.

i only want it to listen and execute when it is needed.
i do not need a process that is constantly listening.
