How to start DHCP service on OpenNMS server.

By default , you cannot start DHCP Service on OpenNMS server because OpenNMS server has installed DHCP client. If you want to start DHCP Server on same OpenNMS server , please stop DHCP client before.

These are steps :

1. Check all services which start from OpenNMS
   

   # opennms -v status

2. You should find :
   

   OpenNMS.Dhcpd          : running

3. Disable this service by comment this service in /opt/opennms/etc/service-configuration.xml :

   1 2 3 4 5 6 7 8 9

   <!-- <service> <name>OpenNMS:Name=Dhcpd</name> <class-name>org.opennms.netmgt.dhcpd.jmx.Dhcpd</class-name> <invoke at="start" pass="1" method="start"></invoke> <invoke at="status" pass="0" method="status"></invoke> <invoke at="stop" pass="0" method="stop"></invoke> </service> -->

4. Restart OpenNMS :
   # service opennms restart
5. Start DHCP service :
   # service dhcpd start
