Server fails to start after Centos 7 update

httpd fails to start during boot

The final problem was that

#!/bin/sh
# This is a NetworkManager dispatcher script to turn http on
# when the network is ready.  MXM
# /etc/NetworkManager/dispatcher.d/22-httpd
# https://wiki.archlinux.org/index.php/NetworkManager#Network_services_with_NetworkManager_dispatcher

if [ "$2" = "up" ]; then
	systemctl start httpd
fi

if [ "$2" = "down" ]; then
	systemctl stop httpd
fi

exit 0
