Best way to allow PHP/Apache to access /usr/bin/sensors

Philippe23

I've got a PHP script that runs /usr/bin/sensors show the temperature of the CPU on a webpage live. I've upgraded to a Hardened kernel that doesn't allow this anymore.

What's the best way to allow this access? sudo? Is there a way to do it with ACLs? Something else?

Hi,

If you don't want to install a fully-fledged system monitor like Nagios or Cacti or something like that (IMHO they are flexible and robust but also a bit complex), you may simply read the data that sensors see.

This is an example in my home box.

Hey Paul,

Thanks for your answer. (I actually do have Munin installed, but it only updates every minute or so: this is a more real-time reading.)

So that morphs the question to: What's the best way to allow PHP/Apache to access that file?

Hi!

According to some tests I did, apache user can access that file without any issue. This means that PHP also can access it, so everything is reduced to a fopen instruction

Hth,

Paul.
