./sbin/icinga2 feature enable need run as root

[Esteban2812]

Expected Behavior

I expect to enable feature without being root user.

Current Behavior

When I'm logged with non-root user "icinga" for example, I perform following command and I got message error:

su - icinga
cd /apps/opt/icingadir2
-bash-4.1$ ./sbin/icinga2 feature enable ido-mysql
critical/cli: This command must be run as root.

Possible Solution

The solution that worked for me is to allow icinga to sudo the binary command /apps/opt/icingadir2/lib64/icinga2/sbin/icinga2

visudo
icinga ALL=(root) NOPASSWD:/apps/opt/icingadir2/lib64/icinga2/sbin/icinga2

and change last line in the script ./sbin/icinga2 to use sudo
exec sudo $ICINGA2_BIN "$@"

Steps to Reproduce (for bugs)

1. su - icinga
2. cd /apps/opt/icingadir2
3. -bash-4.1$ ./sbin/icinga2 feature enable ido-mysql
    critical/cli: This command must be run as root.

Context

This is custom installation from source.

Your Environment

• Version used (icinga2 --version):
  icinga2 - The Icinga 2 network monitoring daemon (version: r2.6.3-1)
• Operating System and version:
  Linux version 2.6.32-642.11.1.el6.x86_64 (mockbuild@c1bm.rdu2.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC) ) Add notes about certificate permission  #1 SMP Fri Nov 18 19:25:05 UTC 2016
• Enabled features (icinga2 feature list):
  Disabled features: api command compatlog debuglog gelf graphite influxdb livestatus logstash opentsdb perfdata redis statusdata syslog
  Enabled features: checker ido-mysql mainlog notification

Concern

As I compiled source with no-root user,
could you tell me why /apps/opt/icingadir2/lib64/icinga2/sbin/icinga2 is required to run as root?
I asked because for sure my SA (System Administrator) will ask.

Icinga 2 isn't built for custom environments which don't require root permissions. There's an ongoing discussion about changing this in #4947. Don't expect it to happen any time soon as our officially supported packages work just fine. I'm closing this as duplicate.
