Overview

This document describes how to install SeerEngine-DC Neutron plug-ins on OpenStack deployed by

using Kolla-Ansible.

Neutron is a type of OpenStack services used to manage all virtual networking infrastructures (VNIs)

in an OpenStack environment. It provides virtual network services to the devices managed by

OpenStack computing services. It allows tenants to create advanced virtual services, such as a

firewall (FW), load balancer (LB), and virtual private network (VPN).

SeerEngine-DC Neutron plug-ins are developed for the SeerEngine-DC controller based on the

OpenStack framework. The following SeerEngine-DC Neutron plug-ins are available:

•

SeerEngine-DC Neutron Core plug-ins—Includes networks, subnets, routers, and ports and

provides tenants with core basic network communication capabilities.

•

SeerEngine-DC Neutron L3_Routing plug-in—Allows tenants to forward traffic to each other

at Layer 3.

•

SeerEngine-DC Neutron FWaaS plug-in—Allows tenants to create firewall services.

•

SeerEngine-DC Neutron LBaaS plug-in—Allows tenants to create LB services.

•

SeerEngine-DC Neutron VPNaaS plug-in—Allows tenants to create VPN services.

The SeerEngine-DC Neutron plug-ins allow deployment of the network configuration obtained from

OpenStack through REST APIs on the SeerEngine-DC controller, including tenants' networks,

subnets, routers, ports, FW, LB, and VPN settings.

CAUTION:

To avoid

service interruptions, do not modify the settings issued by the cloud platform on the

controller

, such as the virtual link layer network, vRouter, and vSubnet settings after the plug-ins

connect to the OpenStack cloud platform.

Preparing for installation

Hardware requirements

Table 1 shows the hardware requirements for installing the SeerEngine-DC Neutron plug-ins on a

server or virtual machine.

Table 1 Hardware requirements

CPU Memory size Disk space

Single-core and multicore

CPUs 2 GB and above 5 GB and above

Software requirements

You can install the SeerEngine-DC Neutron plug-ins on OpenStack Pike deployed by using

Kolla-Ansible.

IMPORTANT:

Before you install the OpenStack plug

-ins, make sure the following requirements are met:

•

Your system has a reliable Internet connection.

•

OpenStack has been deployed correctly. Verify that the /etc/hosts

file on all nodes has the host

name-IP address mappings, and the OpenStack Neutron extension services (Neutron-FWaas,

Neutron-VPNaas, or Neutron-LBaas) have been deployed. For the deployment procedure, see

the installation guide for the specific OpenStack version on the OpenStack official website.

NOTE:

For the installation of converged version of

SeerEngine_DC plug-ins

(

SeerEngine_DC_PLUGIN-version-py2.7.egg), see H3C SeerEngine-DC OpenStack Converged

Plug-Ins Installation Guide.

Deploying OpenStack by using Kolla

Ansible

Before installing the plug-ins, deploy OpenStack by using Kolla Ansible first. For the OpenStack

deployment procedure, see the installation guide for the specific OpenStack version on the

OpenStack official website.

Preprovisioning basic SeerEngine-DC

settings

This procedure preprovisions only basic SeerEngine-DC settings. For the configuration in a specific

scenario, see the SeerEngine-DC configuration guide for that scenario.

Installing OpenStack plug-ins

The SeerEngine-DC Neutron plug-ins are installed on the OpenStack control node.

Setting up the basic environment

Before installing SeerEngine-DC Neutron plug-ins on the OpenStack control node, set up the basic

environment on the node.

To set up the basic environment:

1. Update the software source list, and then download and install the Python tools.

The following uses commands on a CentOS operating system as an example.

[root@controller ~]# yum clean all

[root@controller ~]# yum makecache

[root@controller ~]# yum install –y python-pip python-setuptools

2. Install runlike.

[root@controller ~]# pip install runlike

3. Access the neutron_server container and edit the /etc/hosts file. Add the following

information to the file.

IP and name mappings of all hosts in this OpenStack environment. To obtain this

information, access the SeerEngine-DC controller and select Provision > Domains >

Hosts.

IP and name mappings of all leaf, spine, and border devices in this scenario. To obtain this

information, access the SeerEngine-DC controller and select Provision > Inventory >

Devices.

Installing the SeerEngine-DC Neutron plug-ins

Obtaining the SeerEngine-DC Neutron plug-in installation

package

The SeerEngine-DC Neutron plug-ins are included in the SeerEngine-DC OpenStack package.

Obtain the SeerEngine-DC OpenStack package of the required version and then save the package

to the target installation directory on the server or virtual machine.

Alternatively, transfer the installation package to the target installation directory through a file transfer

protocol such as FTP, TFTP, or SCP. Use the binary transfer mode to prevent the software package

from being corrupted during transit.

Installing the SeerEngine-DC Neutron plug-ins on the

OpenStack control node

1. Create the startup scripts for the neutron-server and h3c-agent containers.

[root@controller ~]# runlike neutron_server>docker-neutron-server.sh

[root@controller ~]# cp docker-neutron-server.sh docker-h3c-agent.sh

[root@controller ~]# sed -i 's/neutron-server/h3c-agent/g' docker-h3c-agent.sh

[root@controller ~]# sed -i 's/neutron_server/h3c_agent/g' docker-h3c-agent.sh

2. Modify the neutron.conf configuration file.

a. Use the vi editor to open the neutron.conf configuration file.

[root@controller ~]# vi /etc/kolla/neutron-server/neutron.conf

b. Configure the neutron.conf configuration file based on the operating system running in the

Kolla environment.

−If a CentOS operating system runs in the Kolla environment, see H3C SeerEngine-DC

Controller OpenStack Plug-Ins Installation Guide for CentOS to configure the

neutron.conf configuration file.

−If a Ubuntu operating system runs in the Kolla environment, see H3C SeerEngine-DC

Controller OpenStack Plug-Ins Installation Guide for Ubuntu to configure the

neutron.conf configuration file.

IMPORTANT:

•

In the neutron_server configuration directory (/etc/kolla/neutron-server/), you can

configure the service_provider parameter for a service once only. If you have

configured the service_provider parameter for the firewall service in the neutron.conf

configuration file, do not configure the service_provider parameter in the

fwaas_driver.ini file. This rule applies also to the LBaaS and PNaaS services.

•

For h3c_agent to load the driver correctly, change the FWaaS driver value in the

/etc/kolla/neutron-server/fwaas_driver.ini file to

networking_h3c.fw.h3c_fwplugin_driver.H3CfwaasDriver.

3. Modify the ml2_conf.ini configuration file.

a. Use the vi editor to open the ml2_conf.ini configuration file.

[root@controller ~]# vi /etc/kolla/neutron-server/ml2_conf.ini

b. Press Ito switch to insert mode, and set the parameters in the ml2_conf.ini configuration

file.

[ml2]

type_drivers = vxlan,vlan

tenant_network_types = vxlan,vlan

mechanism_drivers = ml2_h3c

extension_drivers = ml2_extension_h3c,qos

[ml2_type_vlan]

network_vlan_ranges = physicnet1:1000:2999,port_security

[ml2_type_vxlan]

vni_ranges = 1:500

c. Press Esc to quit insert mode, and enter :wq to exit the vi editor and save the ml2_conf.ini

file.

4. Modify the neutron.conf configuration file and add plug-ins configuration items.

a. Use the vi editor to open the neutron.conf configuration file.

[root@controller ~]# vi /etc/kolla/neutron-server/neutron.conf

b. Add the configuration items in the ml2_conf_h3c.ini file to neutron.conf based on the

operating system running in the Kolla environment.

−If a CentOS operating system runs in the Kolla environment, see H3C SeerEngine-DC

Controller OpenStack Plug-Ins Installation Guide for CentOS to add the configuration

items.

−If a Ubuntu operating system runs in the Kolla environment, see H3C SeerEngine-DC

Controller OpenStack Plug-Ins Installation Guide for Ubuntu to add the configuration

items.

5. Copy the plug-ins installation package to the neutron_server container.

[root@controller ~]# docker cp SeerEngine_DC_PLUGIN-D3601_pike_2017.10-py2.7.egg
