1 Power button action is suspend
CentOS 6’s power button action is shutdown, but CentOS 7’s power button action is suspend as below.
[ 85.247233] Freezing user space processes … (elapsed 0.001seconds) done.[ 85.249541] Freezing remaining freezable tasks … (elapsed 0.001seconds) done.[ 85.251926] Suspending console(s) (use no_console_suspend to debug)
Fedora 22’s power button action is suspend too. But Fedora 23’s power button action is shutdown again. This might be a different way with a way of using default value.
You can change power button action for each user with gsetting and gconf-editor. But you cannot change power button action before login.
In case of virtual machine, you must login to guest machine CentOS 7 for shutdown CentOS 7.
There are some discussion about this power button action like tablet and customizing default value. I think that this action should be shutdown for PC like Fedora 23.
2 Rebuild gnome-settings-daemon
The following script will install gnome-settings-daemon which has shutdown as power button action. After reboot, CentOS 7 can be shutdown with power button.
