RHEL 的 OpenStack (十二)--管理 Heat Orchestration 服務

Heat Orchestration 服務

Heat Orchestration 服務是為了 OpenStack 雲，提供一種基於樣板的編制工程方式，用於建立、管理雲端架構資源！
Hear Orchestration 服務，由下列幾項元件組成：

• heat-cfn
• heat-api
• heat-api-cfn
• heat-engine
• heat-api-cloudwatch
• heat-cfntools 以及 cloud-init 套件

練習1:

1. # source /root/keystonerc_admin
2. # yum list openstack-heat* python-heatclient heat-cfntools
3. # grep 10.1.1.1 /etc/heat/heat.conf
4. # keystone user-get heat
5. # keystone service-get heat
6. # keystone catalog --service orchestration
7. # keystone user-get heat-cfn
8. # keystone service-get heat-cfn
9. # keystone catalog --service cloudformation
10. # keystone user-role-list --user heat --tenant services
11. # openstack-service status heat

設定Heat Orchestration 服務

設定檔包含項目：

• 建立預設的 Nova 浮動IP池，Heat 將會從這個池分配浮動IP
• 指定預設的浮動IP池
• 設定 DNS 轉址
• 建立各式 Nova 樣板，管理員可以用於 Heat 樣板中
• 建立 Heat 可用的 Keystone 使用者

練習2:

1. # source /root/keystonerc_admin
2. # nova floating-ip-pool-list
3. # crudini --get /etc/nova/nova.conf DEFAULT default_floating_pool
4. # crudini --set /etc/nova/nova.conf DEFAULT default_floating_pool public
5. # openstack-service restart nova
6. # crudini --set /etc/neutron/dhcp_agent.ini DEFAULT dnsmasq_dns_servers 10.1.1.254
7. # openstack-service restart neutron --> 另一部主機也需要做
8. # nova flavor-create web.tiny auto 1024 20 1
9. # keystone tenant-create --name heatproject
10. # keystone user-create --name heatuser --pass redhat
11. # keystone user-role-add --user heatuser --role _member_ --tenant heatproject
12. # keystone user-role-add --user heatuser --tenant heatproject --role heat_stack_owner
13. # vim /root/keystonerc_heatuser
14. # source /root/keystonerc_heatuser
15. # glance image-list
16. # neutron net-list
17. # neutron net-create net1
18. # neutron subnet-create --name subnet1 net1 192.168.0.0/24
19. # neutron router-create router1
20. # neutron router-gateway-set router1 public
21. # neutron router-interface-add router1
22. # nova keypair-add --pub-key /root/.ssh/id_rsa.pub heatkey
23. # nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
24. # nova secgroup-add-rule default tcp 80 80 0.0.0.0/0
25. # nova secgroup-add-rule default tcp 443 443 0.0.0.0/0
26. # nova secgroup-add-rule default tcp 3306 3306 0.0.0.0/0
27. # nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0

啟動與驗證 Stack

太複雜，先跳過...
練習3:

1. 先編好一個檔案：multi.template
2. # source /root/keystonerc_heatuser
3. # neutron subnet-list
4. # neutron net-list
5. # vim /root/env.yaml
   parameters:
   key_name: heatkey
   public_net_id: <上一項指令的ID>
   private_net_id: <上一項指令的ID>
   private_subnet_id: <上兩項指令的ID>
   
6. # heat stack-create -r -f multi.tempate -e /root/env.yaml multi
7. # heat stack-list
8. 在一部主機上 # virsh list
9. # heat stack-show multi
10. # heat event-list multi
11. # nova list
12. # ssh root@10.1.1.10
13. # ssh ec2-user@10.1.1.10
14. $ su - 
15. # systemctl status httpd.service
16. # exit
17. $ exit
18. # ssh ec2-user@10.1.1.11
19. $ sudo systemctl status mariadb.service
20. $ exit
21. 移除 Stack
    • # heat stack-delete multi
