先簡單記錄一下步驟。備忘...
install 步驟
0.準備信息，包括
Server names
IP addresses
Server Roles
PXE MAC addresses
PXE IP addresses
PXE interfaces
IPMI/iLO IP address, username, password
1.安裝iso系統，部署lifecycle
2.拷貝tar文件解壓
3.運行hos-init.bash（export HOS_INIT_AUTO=y #添加後不提示ssh保護密碼）
3.1 安裝完成，顯示：
To continue installation copy your cloud layout to:
/home/stack/helion/my_cloud/definition
Then execute the installation playbooks:
cd /home/stack/helion/hos/ansible
git add -A
git commit -m 'My config'
ansible-playbook -i hosts/localhost cobbler-deploy.yml
ansible-playbook -i hosts/localhost bm-rep_w_picpath.yml
ansible-playbook -i hosts/localhost config-processor-run.yml
ansible-playbook -i hosts/localhost ready-deployment.yml
cd /home/stack/scratch/ansible/next/hos/ansible
ansible-playbook -i hosts/verb_hosts site.yml
目錄結構：
helion/ Top level directory
helion/examples/ Directory contains the config input files of the example clouds
helion/my_cloud/definition/ Directory contains the config input files
helion/my_cloud/config/ Directory contains .j2 files which are symlinks to the /hos/ansible directory
helion/hos/ Directory contains files used by the installer
4.圖形安裝，訪問 http://<lifecycle manager_IP>:79/dayzero 。圖形安裝後會禁用服務，啓用方法：
sudo a2ensite dayzero-apache.conf
sudo systemctl start dayzero.service
4.拷貝模版文件
cp -r ~/helion/examples/entry-scale-kvm-vsa/* ~/helion/my_cloud/definition/
[可選項]加密iLo密碼
cd ~/helion/hos/ansible
export HOS_USER_PASSWORD_ENCRYPT_KEY=<encryption key>
./hosencrypt.py
把相應的加密密碼修改到 ~/helion/my_cloud/definition/data/servers.yml
5.提交配置到本地git倉庫
cd ~/helion/hos/ansible
git add -A
git commit -m "My config or other commit message"
6.使用自動化系統安裝
第一部分：部署Cobbler
1.確認iLo可以連接並控制服務器電源。
cd ~/helion/hos/ansible
ansible-playbook -i hosts/localhost bm-power-status.yml
2.部署Cobbler
cd ~/helion/hos/ansible
ansible-playbook -i hosts/localhost cobbler-deploy.yml
第二部分：Image the Nodes
1.安裝後關閉節點電源
2.設定節點網絡啓動爲硬件啓動順序的第一位。
3.打開電源，節點通過遷移步驟從網絡啓動安裝系統。
4.等待節點關機（表示安裝完成），需要一定的時間。
5.在所有節點設定從硬盤啓動
6.等待節點的ssh可用並驗證。
The rep_w_picpath command is:
cd ~/helion/hos/ansible
ansible-playbook -i hosts/localhost bm-rep_w_picpath.yml [-e nodelist=node1,node2,node3]
查看是否所有節點網絡啓動是打開的
sudo cobbler system find --netboot-enabled=1
7.運行配置處理程序
cd ~/helion/hos/ansible
ansible-playbook -i hosts/localhost config-processor-run.yml
上面的命令會提示兩個密碼，也可以把它們放在命令行裏
ansible-playbook -i hosts/localhost config-processor-run.yml -e encrypt="" -e rekey=""
8.配置 TLS（傳輸層安全，SA證書等） 略
9.部署雲
1.創建部署目錄
cd ~/helion/hos/ansible
ansible-playbook -i hosts/localhost ready-deployment.yml
2.擦除磁盤數據[可選項]
cd ~/scratch/ansible/next/hos/ansible
ansible-playbook -i hosts/verb_hosts wipe_disks.yml
3.運行部署腳本（時間在45分鐘以上）
cd ~/scratch/ansible/next/hos/ansible
ansible-playbook -i hosts/verb_hosts site.yml
如果之前運行配置處理程序config-processor-run.yml使用了密碼，使用密碼提示
ansible-playbook -i hosts/verb_hosts site.yml --ask-vault-pass
4.驗證網絡正確工作，從控制節點 ping /etc/hosts 中的所有IP。
