5 Introduction 1 Introduction Red Hat OpenStack is a cloud computing software platform. It is primarily deployed as an Infrastructure as a Service (IaaS) solution. The technology consists of a series of interrelated projects that control pools of processing, storage and networking resources throughout a data center. This can be managed through a web-based dashboard, command-line tools or a RESTful API. Red Hat OpenStack lets users deploy Virtual Machines and other instances that handle different tasks for managing a cloud environment on the fly. With Red Hat OpenStack, horizontal scaling is easy more instances can be spun up in order to serve more users, as needed. The KEMP Load Balancer as a Service (LBaaS) OpenStack driver allows the KEMP LoadMaster to be deployed in Red Hat OpenStack. 1.1 Document Purpose This document explains how to install the KEMP LBaaS driver in Red Hat OpenStack and how to deploy a LoadMaster instance in Red Hat OpenStack. 1.2 Intended Audience This document is for anyone who is interested in finding out how to install and use the KEMP LBaaS Red Hat OpenStack driver.

6 KEMP LBaaS Red Hat OpenStack Driver 2 KEMP LBaaS Red Hat OpenStack Driver For instructions on how to install and use the KEMP LBaaS OpenStack driver, refer to the sections below. 2.1 Prerequisites The following prerequisites must be in place before following these steps: Red Hat OpenStack 8.0 (Liberty release) must be deployed. A LoadMaster must be deployed within OpenStack. Some of the commands in this document may require sudo or root access. The Application Program Interface (API) must be enabled on the LoadMaster. For instructions on how to do this, refer to the steps below: a) In the LoadMaster Web User Interface (WUI), go to Certificates & Security > Remote Access. Figure 2-1: Enable API Interface b) Select the Enable API Interface check box. 2.2 Install the KEMP LBaaS Red Hat OpenStack Driver Package The package can either be installed automatically (if a network connection is in place) or manually. Refer to the relevant section below for further information Enable LBaaS in Red Hat OpenStack To enable LBaaS, open the Red Hat Command Line Interface (CLI) and follow the steps below: 1. Edit the local_settings.py file: vim /etc/openstack-dashboard/local_settings.py 2. Find the following block of code: OPENSTACK_NEUTRON_NETWORK = { 'enable_lb': False } Copyright KEMP Technologies, Inc. All Rights Reserved. 6

7 KEMP LBaaS Red Hat OpenStack Driver 3. Change False to True: OPENSTACK_NEUTRON_NETWORK = { 'enable_lb': True } True is case sensitive and the case should be exactly as it is in this document. 4. Save the file. 5. Restart the web server: service apache2 restart Automatically Install the Driver Package To automatically install the driver package, open the Red Hat CLI and enter the following command: pip install <NameOfKEMPOpenStackDriver> For example: pip install kemptech-openstack-lbaas Manually Install the Driver Package To manually install the driver package, follow the steps below: 1. Go to the following link: 2. Download the.tar.gz file provided. 3. Extract the.tar.gz file. 4. In the Red Hat CLI, find the relevant Python path by running the following commands: python import sys sys.path The default path is usually /usr/lib/python2.7/dist-packages. 5. Copy the downloaded kemptech_openstack_lbaas folder into the dist-packages folder. If updating the KEMP driver package, overwrite the existing files. Copyright KEMP Technologies, Inc.

8 KEMP LBaaS Red Hat OpenStack Driver Enable LBaaS Neutron with the KEMP LoadMaster Driver Configure the neutron.conf and neutron_lbaas.conf files to use the KEMP LBaaS plugin. To do this, follow the steps below: 1. Edit the neutron.conf configuration file: vim /etc/neutron/neutron.conf 2. Find the service_plugins line and add neutron_lbaas.services.loadbalancer.plugin.loadbalancerpluginv2, for example: service_plugins = router,neutron_lbaas.services.loadbalancer.plugin.loadbalancerpluginv2 A comma (,) is used to separate different service plugins. 3. At the bottom of the file, add the following: [kemptechnologies] lm_address = <LoadMasterIPAddress> lm_username = <LoadMasterUsername> lm_password = <LoadMasterPassword> For example: [kemptechnologies] lm_address = lm_username = bal lm_password = test Save the changes to the edited file. 5. Edit the neutron_lbaas.conf configuration file: vim /etc/neutron/neutron_lbaas.conf 6. Save the changes to the edited file. 7. Go down to the [service_providers] section and add (or append, as needed) the following line: service_provider = LOADBALANCERV2:kemptechnologies:neutron_lbaas.drivers.kemptechnologies.dr iver_v2.kemploadmasterdriver:default This is case sensitive. If there are other LBaaS entries in the list, ensure the KEMP Technologies one is set as the default. Copyright KEMP Technologies, Inc. All Rights Reserved. 8

9 KEMP LBaaS Red Hat OpenStack Driver 8. Restart Neutron by running the following command: service neutron-server restart 2.3 Topology Setup Refer to the commands below to find out how to create a load balancer, listener, pool, members and health monitor: Get the Universally Unique Identifier (UUID) of the private subnet: neutron subnet-list Create a load balancer: neutron lbaas-loadbalancer-create --name lb1 private-subnet Create a listener (health check): neutron lbaas-listener-create --loadbalancer lb1 --protocol HTTP --protocol-port 80 --name listener1 Create a pool and associate it with the previously created listener: neutron lbaas-pool-create --lb-algorithm ROUND_ROBIN --listener listener1 -- protocol HTTP --name pool1 Create members (Real Servers): neutron lbaas-member-create --subnet private-subnet --address <ServerIPAddress> --protocol-port 80 pool1 Create a health monitor and associate it with the pool: neutron lbaas-healthmonitor-create --delay 3 --type HTTP --max-retries 3 --timeout 3 --pool pool1 2.4 Updating the Driver Package To update the driver package, refer to the relevant point below: Automatic: Run the following command in the Red Hat CLI: pip install -U <NameOfKEMPOpenStackDriver> For example: pip install --upgrade kemptech-openstack-lbaas Manual: To manually update the driver package, follow the steps in Section but overwrite the existing files.
