ocf_heartbeat_dhcpd(7) Chrooted ISC DHCP server resource agent.

SYNOPSIS

DESCRIPTION

Manage an ISC DHCP server service in a chroot environment.

SUPPORTED PARAMETERS

config

The absolute path to the DHCP server configuration file.

(unique, required, string, no default)

chrooted

Configure the dhcpd service to run in a chrooted or non-chrooted mode.

(unique, optional, boolean, default true)

chrooted_path

The absolute path of the chrooted DHCP environment.

(unique, optional, string, default "/var/lib/dhcp")

binary

The binary for the DHCP server process. An absolute path definition is not required, but can be used to override environment path.

(optional, string, default "dhcpd")

user

The system user the DHCP server process will run as when it is chrooted.

(optional, string, default "dhcpd")

group

interface

The network interface(s) the DHCP server process will bind to. A blank value will bind the process to all interfaces.

includes

This parameter provides a means to copy include files into the chrooted environment. If a dhcpd.conf file contains a line similar to this:

Then an admin also has to tell the dhcpd RA that this file should be pulled into the chrooted environment. This is a space delimited list.

(optional, string, no default)

The leases database file, relative to chrooted_path.

(optional, string, default "/db/dhcpd.leases")

pid

The path and filename of the PID file. It is relative to chrooted_path.
