Openstack Walkthrough-----08-Compute Node Neutron configuration

Neutron component Installation

[email protected] ~]# Yum install Openstack-neutron-linuxbridge ebtables ipset

Configuring Common Components

Networking Common components configuration includes authentication mechanisms, Message Queuing, and plug-ins

Edit the "/etc/neutron/neutron.conf" file and complete the following:

• In the ' [Database] ' section, note all ' connection ' items because the compute nodes do not directly access the database.

• In the ' [DEFAULT] ' section, configure the ' RabbitMQ ' Message Queue access rights:

Transport_url = Rabbit://openstack:[email protected]

• In the "[DEFAULT]" and "[Keystone_authtoken]" sections, configure authentication Service access:

Auth_strategy = Keystoneauth_uri = Http://192.168.56.11:5000auth_url = Http://192.168.56.11:35357memcached_servers = 192.168.56.11:11211auth_type = Passwordproject_domain_name = Defaultuser_domain_name = Defaultproject_name = Serviceusername = Neutronpassword = Neutron

in the [oslo_concurrency] section, configure the lock path:

Lock_path =/var/lib/neutron/tmp

Configure calculations using of network services

Configuring the Linuxbridge Agent

The configuration and control nodes are the same here, so we have a copy of the control node configuration.

[Email protected] ~]# Scp/etc/neutron/plugins/ml2/linuxbridge_agent.ini 192.168.56.12:/etc/neutron/plugins/ml2/[ Email protected] ' s Password:linuxbridge_agent.ini

Edit the '/etc/nova/nova.conf ' file and do the following:

• In the ' [Neutron] ' section, configure the Access parameters:

[Neutron]url = Http://192.168.56.11:9696auth_url = Http://192.168.56.11:35357auth_type = Passwordproject_domain_name = Defaultuser_domain_name = Defaultregion_name = Regiononeproject_name = Serviceusername = Neutronpassword = Neutron

Installation Complete

Restart COMPUTE Service:

[[email protected] ~]# systemctl restart Openstack-nova-compute.service[[email protected] ~]# PS Aux|grep NovaNova 21      400 56.7 6.9 1661432 130576? SSL 23:19 0:11/usr/bin/python2/usr/bin/nova-computeroot 21433 0.0 0.0 112644 952 pts/0 s+ 23:19 0:00 grep--color=auto Nova

Start the Linuxbridge agent and configure it to boot from:

[Email protected] ~]# systemctl enable neutron-linuxbridge-agent.servicecreated symlink from/etc/systemd/system/ Multi-user.target.wants/neutron-linuxbridge-agent.service to/usr/lib/systemd/system/ Neutron-linuxbridge-agent.service. [Email protected] ~]# systemctl start Neutron-linuxbridge-agent.service

Validation services

We see whether the compute nodes are received from the control node:

The service installation to this compute node was successful ~~~~~~~

Below we will learn to launch an instance!!!
