Handle some edge cases? about php-fpm_tuner

[dualmi]

Could be replaced with /proc/meminfo result

        if (preg_match('~MemFree:\s+(\d+)\s+~', shell_exec('cat /proc/meminfo'), $matches)) {
            $freeMemory = $matches[1] / 1024;
        }

Yes. Would you like to prepare a pull request?

What's the free replacement on that system? What the system is?

[tomaszkane]

Docker container ;-)
I think about handle like:

if shell_exec "command free" === false then echo "Free command is not available on this system. Cannot tune FPM."

[samdark]

Alpine? free isn't the only way of how the info could be obtained.
