Tungsten Fabric入門寶典丨關於安裝的那些事（下）
（編者按：在 上一篇文章中，我們聊了關於TF元件安裝中的HA行為、多NIC安裝、叢集規模等問題，以及如何安裝具有Tungsten Fabric CNI的Kubernetes HA環境。）
OpenStack
Openstack HA的安裝可以由anstack-deployer直接完成。
對於此示例的設定，我使用了5個EC2例項（AMI相同，ami-3185744e），每個例項具有2個vCPU、8 GB記憶體、20 GB磁碟空間。VPC的CIDR為172.31.0.0/16。
yum -y install epel-release yum -y install git ansible-2.4.2.0 ssh-keygen cd .ssh/ cat id_rsa.pub >> authorized_keys cd git clone cd contrail-ansible-deployer vi config/instances.yaml (replace contents with this) provider_config: bms: ssh_user: root ssh_public_key: /root/.ssh/id_rsa.pub ssh_private_key: /root/.ssh/id_rsa domainsuffix: local ntpserver: 0.centos.pool.ntp.org instances: bms1: provider: bms ip: 172.31.6.90 # controller1's ip roles: config_database: config: control: analytics: webui: openstack: bms2: provider: bms ip: 172.31.25.90 # controller2's ip roles: config_database: config: control: analytics: webui: openstack: bms3: provider: bms ip: 172.31.31.242 # controller3's ip roles: config_database: config: control: analytics: webui: openstack: bms11: provider: bms ip: 172.31.42.209 # compute1's ip roles: vrouter: openstack_compute: bms12: provider: bms ip: 172.31.15.199 # compute2's ip roles: vrouter: openstack_compute: contrail_configuration: RABBITMQ_NODE_PORT: 5673 AUTH_MODE: keystone KEYSTONE_AUTH_URL_VERSION: /v3 JVM_EXTRA_OPTS: "-Xms128m -Xmx1g" kolla_config: kolla_globals: kolla_internal_vip_address: 172.31.0.11 ## kolla-ansible will deploy haproxy to serve HA vip kolla_passwords: keystone_admin_password: contrail123 # admin user's password global_configuration: ## if previously described AMI is used, it uses cloud-init packages whose rpm dependency is not compatible with ansible-deployer in R5.1 and later. To workaroud this, I used these commands. yum -y remove PyYAML python-requests easy_install pip pip install PyYAML requests pip install ansible ansible-playbook -e orchestrator=openstack -i inventory/ playbooks/configure_instances.yml - it takes about 10 minutes ansible-playbook -e orchestrator=openstack -i inventory/ playbooks/install_openstack.yml - it takes about 40 minutes ansible-playbook -e

注意：如果計算節點不支援kvm，則可能需要新增此設定。
注意：如果是使用AWS，則還需要從EC2例項的右鍵選單中設定網路>管理IP地址，以允許從其它節點訪問haproxy VIP。
這樣，控制器之間的HA和2個計算節點之間的overlay都完全配置好了！
有些要點本文件沒有覆蓋，例如某些控制節點當機時的行為，或在計算節點之間執行實時遷移。上次我嘗試實時遷移時，發現有大約1秒鐘的報文丟包，但是請注意自己的設定，因為有很多要注意的地方（例如字首將在實時遷移完成後更新）。
檢視每個控制器的鄰居狀態和路由表，您會發現它們之間的有趣之處。

由於vRouter始終具有2個XMPP連線，所以當存在3個控制器時，XMPP的連線狀態在控制器之間是不同的，並且它們之間的路由表也可能有所不同。考慮到路由目標過濾，如果某些控制器未從XMPP接收到某些特定的路由目標，則它們甚至可能具有完全不同的路由表。
這就是由於Tungsten Fabric的橫向擴充套件行為帶來的結果。
有關ansible-ployer的更詳細的配置（包括多NIC示例），您可以看看這些文件。
vCenter
Tungsten Fabric可以很好地與vCenter整合在一起，我們在“編排器整合”的部分有所描述。
要嘗試此功能，可以按照以下說明進行操作。
-
-
請注意vRouterVM的OVF檔案目前還未公開提供
由於Tungsten Fabric的HA行為與Kubernetes和OpenStack安裝中的行為完全相同，因此我將不對其進行詳細描述。
對於編排器端的HA，vCenter HA是完全可用的。
- 我尚未嘗試過這種組合，但是由於vCenter HA將使用與vCenter服務相同的IP，因此我認為vcenter-plugin與vCenter HA一起使用的可能性很高。
多vCenter或跨vCenter（使用連結模式時）將是一個很有趣的主題。我將在附錄部分進一步討論它們。
容器標籤的使用
關於在新的安裝中選擇什麼樣的標籤，我有一些考慮。
我經常使用的是三個標籤：latest，5.1.0-latest，5.0-latest。它們位於每個Tungsten Fabric分支的頭部（master/R5.1/R5.0），並且每個分支中都包含各種錯誤修復。因此，您可以為用例選擇其中的標籤。如果需要R5.1中的新功能（例如可選的analytics元件），那麼你可以選擇5.1.0-latest標籤。
由於latest是真正的開發分支，因此我不建議您將它們作為常規使用的標籤，因為在某些情況下，此版本已被“破壞”以新增新的功能。
其它發行版本的分支更加穩定，因為在大多數情況下，它們只是進行了錯誤修復，儘管在建立新的分支後的某些特定時期內，發行版本的分支似乎也具有新的功能。
要指定標籤，您可以使用這些引數，並且當針對ansible-deployer和conutil-container-builder輸入git clone時，還需要指定同一分支。
需要注意的一點是，由於與OpenStack一起使用的容器（例如nova-init、neutron-init、heat-init等）具有OpenStack發行版的版本依賴性，因此標記可能需要更改為5.1.0-latest-queens、5.1.0-latest-rocky等。
由於安裝了一些帶有特定版本的OpenStack模組，因此，如果標籤不同，則OpenStack容器將無法正常工作。
