PackStack一鍵安裝OpenStack

作者：獨筆孤行@TaoCloud
OpenStack自動安裝比手動搭建消耗的硬件資源較大，因此虛擬機或服務器最低配置爲4核CPU+8G內存+20G磁盤，並開啓CPU虛擬化。建議配置爲8核CPU+16G內存或更高配置，並保證服務器能訪問外網。

本次主要測試的成功案例有N、P、Q三個版本，其它版本同樣可以藉助packstack一鍵安裝OpenStack，安裝方式相同。只是Yum源的配置不同而已，主要區別也在於yum源的配置。

成功案例1：Q版OpenStack自動安裝

操作系統：CentOS7.5minimal（其它系統同樣支持）
硬件配置：4vCPU+8G Memory+20G磁盤

1.關閉並禁用防火牆：

# systemctl stop firewalld
# systemctl disable firewalld
# systemctl stop NetworkManager
# systemctl disable NetworkManager

2.關閉selinux：

# setenforce 0

3.編輯/etc/selinux/config文件內容，將SELINUX值enforcing改爲disabled：

SELINUX=disabled

4.配置yum源：

# yum install -y http://rdo.fedorapeople.org/rdo-release.rpm

5.安裝packstack工具

# yum install -y openstack-packstack

6.Packstack一鍵安裝：

# packstack --allinone

註解
無網絡異常時，安裝時間最多不過30分鐘，如果有任務長時間執行無返回結果，需要查看相關日誌查找問題。

成功案例2：N版OpenStack自動安裝

操作系統：CentOS7.4minimal（其它系統同樣支持）
硬件配置：4vCPU+8G Memory+20G磁盤

1.關閉並禁用防火牆：

# systemctl stop firewalld
# systemctl disable firewalld
# systemctl stop NetworkManager
# systemctl disable NetworkManager

2.關閉selinux：

# setenforce 0

3.編輯/etc/selinux/config文件內容，將SELINUX值enforcing改爲disabled：

SELINUX=disabled

4.製作OpenStack-Newton網絡源

cat /etc/yum.repos.d/CentOS-OpenStack-Newton.repo 
[OpenStack-Newton]
name=OpenStack-Newton
baseurl=http://vault.centos.org/7.4.1708/cloud/x86_64/openstack-newton/
gpgcheck=0
enabled=1

5.安裝kvm源

yum install http://mirrors.163.com/centos/7.5.1804/virt/x86_64/kvm-common/centos-release-qemu-ev-1.0-1.el7.noarch.rpm

6.安裝packstack工具

# yum install openstack-packstack

7.Packstack一鍵安裝：

# packstack --allinone

註解
無網絡異常時，安裝時間最多不過30分鐘，如果有任務長時間執行無返回結果，需要查看相關日誌查找問題。

成功案例3：P版OpenStack自動安裝。

操作系統：CentOS7.2（其它系統同樣支持）
硬件配置：4vCPU+8G Memory+20G磁盤

1.關閉並禁用防火牆：

# systemctl stop firewalld
# systemctl disable firewalld
# systemctl stop NetworkManager
# systemctl disable NetworkManager

2.關閉selinux：

# setenforce 0

編輯/etc/selinux/config文件內容，將SELINUX值enforcing改爲disabled：

SELINUX=disabled

3.配置p版yum源

# yum install centos-release-openstack-pike.x86_64

4.禁用掉無法使用的CentOS-QEMU-EV.repo源，可直接刪除該源文件。

# rm -rf /etc/yum.repos.d/CentOS-QEMU-EV.repo

5.手動配置可用的KVM源

[root@OpenStackPike ~]# cat /etc/yum.repos.d/CentOS-KVM.repo 
[CentOS-KVM]
name=CentOS-KVM
baseurl=http://mirror.centos.org/centos/7/virt/x86_64/kvm-common/
gpgcheck=0
enabled=1

6.配置kvm源或執行以下命令安裝：

# rpm -ivh http://mirror.centos.org/centos/7/virt/x86_64/kvm-common/centos-release-qemu-ev-1.0-1.el7.noarch.rpm

7.配置好yum源後安裝applydeltarpm包，防止自動安裝時報錯。

# yum install deltarpm -y

8.安裝packstack工具

# yum install openstack-packstack

9.Packstack一鍵安裝：

# packstack --allinone

常見故障處理排查及使用方法
如下提到的處理方法，適用於以上三個版本的PackStack方式安裝。
1.常見錯誤：

Testing if puppet apply is finished :192.168.20.200_controller.pp
安裝過程卡在此步驟沒有任何反應。
分析：網絡正常情況下此過程不超過30分鐘。時間過長時，需要確認關閉NetworkManger、selinux、firewalld。還可檢查硬件配置，建議4核CPU+8GB內存或更高配置。還無法解決後可添加至2個網卡、2個磁盤。

2.PackStack日誌信息：

PackStack安裝過程中的日誌在 /var/tmp/packstack/ 目錄中。無法解決問題時可查看該目錄下相關日誌信息。

3.常見認證文件：

執行packstack --allinone安裝命令後，會在執行目錄下生成
keystonerc_admin 、keystonerc_demo、packstack-answers-20181025-111102.txt三個文件。可查看keystonerc_admin文件內容獲取登錄Dashboard的用戶名和密碼。安裝過程的相關配置信息記錄在packstack-answers-20181025-111102.txt文件中。執行OpenStack操作命令前需要執行source keystonerc_admin命令h獲取管理員認證。

4.安裝成功過程記錄：

[root@newton ~]# packstack --allinone

以上過程爲安裝成功時的全部信息，由於沒有關閉NetworkManager導致出現警告信息，需要手動執行如下命令關閉NetworkManager：

systemctl disable NetworkManger 
systemctl stop NetworkManager
