Foreman » Installer

Hi,

CentOS Linux release 7.2.1511 (Core)
isc dhcp version 4.2.5 release 42
foreman 1.10.1

When i use the proxy installer from web frontend an error occurs with dhcp. i think the installer dont update correctly the /etc/dhcp/dhcpd.conf.

 foreman-installer   --enable-foreman-proxy   --foreman-proxy-tftp=true   --foreman-proxy-tftp-servername=192.168.85.30   --foreman-proxy-dhcp=true   --foreman-proxy-dhcp-interface=ens3   --foreman-proxy-dhcp-gateway=192.168.85.254   --foreman-proxy-dhcp-range="192.168.85.50 192.168.85.100"   --foreman-proxy-dhcp-nameservers="192.168.85.30,8.8.8.8"   --foreman-proxy-dns=true   --foreman-proxy-dns-interface=ens3   --foreman-proxy-dns-zone=oscloud.local   --foreman-proxy-dns-reverse=85.168.192.in-addr.arpa   --foreman-proxy-dns-forwarders=192.168.85.30   --foreman-proxy-foreman-base-url=https://foreman.oscloud.local   --foreman-proxy-oauth-consumer-key=Y2g69oqFzj4qTMo7SZsQWrmNd7RYBUN2   --foreman-proxy-oauth-consumer-secret=9cc9sm5dfJNLp9NoPvhudMPK4V5RUX5i

after that i get the following error

Could not start Service[dhcpd]: Execution of '/usr/bin/systemctl start dhcpd' returned 1: Job for dhcpd.service failed because the control process exited with error code. See "systemctl status dhcpd.service" and "journalctl -xe" for details.

when i start after that the dhcp server manually i found that the omapi values are not correctly set.

when i check the dhcd.conf

[root@foreman settings.d]# cat /etc/dhcp/dhcpd.conf

1. dhcpd.conf
   omapi-port 7911;
   key {
   algorithm HMAC-MD5;
   secret "";
   }
   omapi-key ;

default-lease-time 43200;
max-lease-time 86400;

ddns-update-style none;

option domain-name "oscloud.local";
option domain-name-servers 192.168.85.30, 8.8.8.8;
option ntp-servers none;

allow booting;
allow bootp;

option fqdn.no-client-update on; # set the "O" and "S" flag bits
option fqdn.rcode2 255;
option pxegrub code 150 = text ;

1. PXE Handoff.
   next-server 192.168.85.30;
   filename "pxelinux.0";

log-facility local7;

include "/etc/dhcp/dhcpd.hosts"; #################################

1. oscloud.local #################################
   subnet 192.168.85.0 netmask 255.255.255.0 {
   pool {
   range 192.168.85.50 192.168.85.100;
   }

option subnet-mask 255.255.255.0;
  option routers 192.168.85.254;
}

you will see that the omapi values are not correctly set. normally it should look like below but i think the installer forget anything. the "omapi" keyword is forgotten ... you will se it above when you compare these two.

omapi-port 7911;
key omapi_key {
algorithm HMAC-MD5;
secret "XXXXXXXXX"; #<-The output from the generated key above.
};
omapi-key omapi_key;

is there a fix for that?

greetings
