[DEPRECATED] Prime Network Registrar (PNR)¶
This is an installation guide for enabling Cisco Prime Network Registrar (PNR) support on OpenStack.
Please refer to PNR installation guide (http://www.cisco.com/c/en/us/support/cloud-systems-management/prime-network-registrar/tsd-products-support-series-home.html) for how to install and bring up the PNR.
The neutron DHCP agent in the OpenStack environment needs to be setup to communicate with the PNR DHCP server and with the PNR DNS server. The PNR DHCP server performs leasing operations and PNR DNS server resolves DNS queries, these two servers replace dnsmasq.
This guide does not cover OpenStack installation.
The prerequisites for installing the PNR OpenStack enabler are the following:
- Install PNR with required DNS and DHCP licenses.
- Disable dnsmasq or other DNS/DHCP services.
3. PNR plugin Installation¶
|3.1 Using devstack:|
In this scenario, the PNR plugin will be installed along with OpenStack using devstack.
Add this repo as an external repository:
> cat local.conf [[local|localrc]] enable_plugin networking-cisco https://git.openstack.org/openstack/networking-cisco.git enable_service net-cisco
|3.2 On a setup with OpenStack already installed:|
In this scenario, the PNR plugin will be installed on a setup which has OpenStack installed already:
sudo python networking_cisco/setup.py install
The following modifications are needed in the
Change the DHCP driver from dnsmasq to PNR.
[DEFAULT] #dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq dhcp_driver = networking_cisco.plugins.cisco.cpnr.dhcp_driver.CpnrDriver
Add the following new section to the
dhcp_agent.inifile with the details for contacting the PNR local server.
[cisco_pnr] http_server = http://<pnr_localcluster_ipaddress>:8080 http_username = <pnr_localcluster_username> http_password = <pnr_localcluster_password> external_interface = eth0 dhcp_server_addr = <pnr_localcluster_ipaddress> dhcp_server_port = 67 dns_server_addr = <pnr_localcluster_ipaddress> dns_server_port = 53
Change the <pnr_localcluster_ipaddress> to the IP address of the local PNR VM.
Change the <pnr_localcluster_username> and <pnr_localcluster_password> to the same username and password provided during PNR installation.
If you are using HTTPS with a valid SSL certificate, change the scheme in http_server config variable to ‘https’ and the port number in the address to the appropriate port (default 8443).
If you do not want to verify SSL certificates, add a config variable to
[cisco_pnr] insecure = True
Note that using the
insecurevariable is NOT recommended in production.
dhcp_agent.ini, restart the DHCP agent.
On Red Hat based server:
systemctl restart neutron-dhcp-agent
On Ubuntu based server:
service restart neutron-dhcp-agent
Start the dhcp and dns relay from command line as a detached background process. The relay files exist in networking_cisco/plugins/cisco/cpnr.
nohup python dhcp_relay.py --config-file /etc/neutron/dhcp_agent.ini --log-file /var/log/neutron/dhcp-relay.log &
nohup python dns_relay.py --config-file /etc/neutron/dhcp_agent.ini --log-file /var/log/neutron/dns-relay.log &
