安裝和配置控制節(jié)點（Controller node）
在配置Openstack網(wǎng)絡(luò)（項目代號為neutron）服務(wù)前，需要創(chuàng)建相關(guān)數(shù)據(jù)庫、服務(wù)認(rèn)證service credentials、API入口endpoints
- 創(chuàng)建數(shù)據(jù)庫
$ mysql -uroot -p
mysql> create database neutron;
mysql> grant all privileges on neutron.* to 'neutron'@'localhost' \
identified by '123456' with grant option;
mysql> grant all privileges on neutron.* to 'neutron'@'%' \
identified by '123456' with grant option;
mysql> exit;
- 切換到
admin用戶環(huán)境，以獲得admin-onlyCLI權(quán)限
$ . admin-openrc
- 創(chuàng)建
neutron服務(wù)認(rèn)證
創(chuàng)建neutron用戶
$ openstack user create --domain default --password-prompt neutron
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field | Value |

| name | neutron |
| password_expires_at | None |
+---------------------+----------------------------------+
neutron用戶添加admin角色
$ openstack role add --project service --user neutron admin
此命令無輸出
創(chuàng)建neutron服務(wù)入口
$ openstack service create --name neutron \
--description "OpenStack Networking" network
+-------------+----------------------------------+

配置 networking 選項
可以選擇option 1或option 2架構(gòu)以部署Networking服務(wù)。
-
Option 1架構(gòu)是最簡單的，只支持將虛擬機實例接入provider(external)網(wǎng)絡(luò)，沒有self-service(private)網(wǎng)絡(luò)、routers以及floating IP(浮動IP)。僅有admin用戶或其他同級用戶可管理provider網(wǎng)絡(luò) -
Option 2架構(gòu)則使用layer-3服務(wù)擴展了option 1，支持虛擬機實例使用self-service網(wǎng)絡(luò)。demo用戶或其他用戶可以自行管理self-service網(wǎng)絡(luò)，包括routers以及floating IP。floating IP可以讓虛擬機實例通過self-service網(wǎng)絡(luò)訪問external網(wǎng)絡(luò)，例如外網(wǎng)。self-service網(wǎng)絡(luò)的數(shù)據(jù)包會使用 1500 的MTU值
Option 2同樣支持將虛擬機實例接入provider網(wǎng)絡(luò)
配置完成下述任一網(wǎng)絡(luò)架構(gòu)后，再回到這里繼續(xù)配置 metadata 代理
- Option 1: Provider 網(wǎng)絡(luò) 部署
-Option 2: Self-service 網(wǎng)絡(luò)
配置metadata agent
metadata agent用于提供配置信息，例如虛擬機實例的憑據(jù)
- 編輯
/etc/neutron/metadata_agent.ini
[DEFAULT]
...
nova_metadata_ip = controller
metadata_proxy_shared_secret = METADATA_SECRET #可以設(shè)置為其他合適的密碼
配置Compute service使用網(wǎng)絡(luò)服務(wù)
- 編輯
/etc/nova/nova.conf
[neutron]
...
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = Default
user_domain_name = Default
region_name = RegionOne
project_name = service
username = neutron
password = 123456
service_metadata_proxy = true
metadata_proxy_shared_secret = METADATA_SECRET
安裝收尾
# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini \
/etc/neutron/plugin.ini
# su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \
--config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
# systemctl restart openstack-nova-api.service
- 對于
option 1和option 2，都需要如下操作
# systemctl enable neutron-server.service \
neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
neutron-metadata-agent.service
# systemctl start neutron-server.service \
neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
neutron-metadata-agent.service
- 對于
option 2，還需要啟用layer-3服務(wù)
# systemctl enable neutron-l3-agent.service
# systemctl start neutron-l3-agent.service
