OpenStack Pike 版本的  Mistral 安裝部署

# 安裝環境使用的centos 7.3 

1. 安裝 Mistral 安裝包。# yum -y install openstack-mistral-api.noarch openstack-mistral-engine.noarch openstack-mistral-executor.noarch openstack-mistral-ui.noarch2. 建立Mistral資料庫。 （密碼自行替換，這邊示例是123456）#mysql -u root -p123456 -e "CREATE DATABASE mistral;"#mysql -u root -p123456 -e "GRANT ALL PRIVILEGES ON mistral.* TO 'mistral'@'localhost' IDENTIFIED BY 'mistral';"#mysql -u root -p123456 -e "GRANT ALL PRIVILEGES ON mistral.* TO 'mistral'@'%' IDENTIFIED BY 'mistral';"3. 建立使用者，並新增role 到mistral使用者和service專案。#openstack user create --domain default --password 123456 mistral# openstack role add --project service --user mistral admin4. 建立 mistral 服務實體.(其中 controller 自行替換。)#openstack service create --name mistral --description 'OpenStack Workflow service' workflowv2#openstack endpoint create --region RegionOne workflowv2 public http://controller:8989/v2#openstack endpoint create --region RegionOne workflowv2 internal http://controller:8989/v2#openstack endpoint create --region RegionOne workflowv2 admin http://controller:8989/v25.編輯 mistral配置檔案。[

5.  初始化mistral的資料庫。#mistral-db-manage --config-file /etc/mistral/mistral.conf upgrade head新增預設的mistral actions (報錯請無視)# mistral-db-manage --config-file /etc/mistral/mistral.conf populate6. 啟動服務。# systemctl enable openstack-mistral-api.service openstack-mistral-engine.service openstack-mistral-executor.service# systemctl start openstack-mistral-api.service openstack-mistral-engine.service openstack-mistral-executor.service

# yum 源，可採用阿里雲的源。
