OpenStack Liberty di Ubuntu 14.04 – Konfigurasi Neutron #2

Ini adalah bagian kedua dari konfigurasi neutron (Networking) di Ubuntu 14.04, Anda dapat membaca artikel sebelumnya di Configure Neutron #1, di mana kami telah menginstal dan mengkonfigurasi komponen Networking pada Controller node.

Di sini, dalam tutorial ini kita akan menginstal dan mengkonfigurasi Compute Node.

Untuk memulainya, Instal komponen pada node komputasi.

# apt-get install neutron-plugin-linuxbridge-agent conntrack

Konfigurasikan Node Komputasi:

Mari kita lakukan beberapa konfigurasi perintah termasuk mekanisme otentikasi, antrian pesan, dan plug-in

Edit file /etc/neutron/neutron.conf.

# nano /etc/neutron/neutron.conf

Buat perubahan yang sesuai pada file.

[DEFAULT]
...
rpc_backend = rabbit
auth_strategy = keystone
verbose = True

[oslo_messaging_rabbit]
...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = password

## Replace "password" with the password you chose for the openstack account in RabbitMQ.

[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = neutron
password = password

## Replace "password" with the password you chose for the neutron user in the Identity service.
## Commentout other authentication details.

[database]

#connection = sqlite:////var/lib/neutron/neutron.sqlite

## Comment out any connection options because compute nodes do not directly access the database.

Konfigurasikan agen jembatan Linux:

Karena kita menggunakan jaringan Self-service, kita perlu mengkonfigurasi agen jembatan Linux pada node Compute. Agen jembatan Linux membuat infrastruktur jaringan virtual layer-2 untuk instance yang mencakup terowongan VXLAN untuk jaringan pribadi dan menangani grup keamanan.

Edit file /etc/neutron/plugins/ml2/linuxbridge_agent.ini.

# nano /etc/neutron/plugins/ml2/linuxbridge_agent.ini

Buat perubahan pada file.

[linux_bridge]
physical_interface_mappings = public:eth1

## Replace "eth1" with the name of the physical public facing network interface.

[vxlan]
enable_vxlan = True
local_ip = 192.168.12.22
l2_population = True

## Replace "192.168.12.22" with the management ip-address of compute node.

[agent]
...
prevent_arp_spoofing = True

[securitygroup]
...
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

Konfigurasikan Compute untuk menggunakan Jaringan:

Edit file /etc/nova/nova.conf.

# nano /etc/nova/nova.conf

Lakukan perubahan pada file seperti di bawah ini.

[neutron]
url = http://controller:9696
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
region_name = RegionOne
project_name = service
username = neutron
password = password

## Replace "password" with the password you chose for the neutron user in the Identity service.

Selesaikan penginstalan:

Mulai ulang layanan Compute:

# service nova-compute restart

Mulai ulang agen jembatan Linux:

# service neutron-plugin-linuxbridge-agent restart

Verifikasi:

Daftar agen untuk memverifikasi keberhasilan peluncuran agen neutron, jalankan perintah ini pada node Controller.

# neutron agent-list
+--------------------------------------+--------------------+--------------------------+-------+----------------+---------------------------+
| id                                   | agent_type         | host                     | alive | admin_state_up | binary                    |
+--------------------------------------+--------------------+--------------------------+-------+----------------+---------------------------+
| 02030132-55f1-4136-8b47-7b495b66c672 | L3 agent           | controller.itzgeek.local | :-)   | True           | neutron-l3-agent          |
| 6b2fd77d-8b23-4932-8010-6436bf01319c | Metadata agent     | controller.itzgeek.local | :-)   | True           | neutron-metadata-agent    |
| 9324094a-878c-4ba2-b822-7b070268deec | DHCP agent         | controller.itzgeek.local | :-)   | True           | neutron-dhcp-agent        |
| cac6003d-b25a-4b1f-8144-1ae0293f26b0 | Linux bridge agent | compute.itzgeek.local    | :-)   | True           | neutron-linuxbridge-agent |
| faec1d38-5b5a-4c46-a614-4db12b4ff9e6 | Linux bridge agent | controller.itzgeek.local | :-)   | True           | neutron-linuxbridge-agent |
+--------------------------------------+--------------------+--------------------------+-------+----------------+---------------------------+

Anda akan melihat output di atas dengan empat agen pada node pengontrol dan satu agen di setiap node komputasi .
