PackStack一键安装OpenStack

作者：独笔孤行@TaoCloud
OpenStack自动安装比手动搭建消耗的硬件资源较大，因此虚拟机或服务器最低配置为4核CPU+8G内存+20G磁盘，并开启CPU虚拟化。建议配置为8核CPU+16G内存或更高配置，并保证服务器能访问外网。

本次主要测试的成功案例有N、P、Q三个版本，其它版本同样可以借助packstack一键安装OpenStack，安装方式相同。只是Yum源的配置不同而已，主要区别也在于yum源的配置。

成功案例1：Q版OpenStack自动安装

操作系统：CentOS7.5minimal（其它系统同样支持）
硬件配置：4vCPU+8G Memory+20G磁盘

1.关闭并禁用防火墙：

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

2.关闭selinux：

# setenforce 0

3.编辑/etc/selinux/config文件内容，将SELINUX值enforcing改为disabled：

SELINUX=disabled

4.配置yum源：

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

5.安装packstack工具

# yum install -y openstack-packstack

6.Packstack一键安装：

# packstack --allinone

注解
无网络异常时，安装时间最多不过30分钟，如果有任务长时间执行无返回结果，需要查看相关日志查找问题。

成功案例2：N版OpenStack自动安装

操作系统：CentOS7.4minimal（其它系统同样支持）
硬件配置：4vCPU+8G Memory+20G磁盘

1.关闭并禁用防火墙：

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

2.关闭selinux：

# setenforce 0

3.编辑/etc/selinux/config文件内容，将SELINUX值enforcing改为disabled：

SELINUX=disabled

4.制作OpenStack-Newton网络源

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.安装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.安装packstack工具

# yum install openstack-packstack

7.Packstack一键安装：

# packstack --allinone

注解
无网络异常时，安装时间最多不过30分钟，如果有任务长时间执行无返回结果，需要查看相关日志查找问题。

成功案例3：P版OpenStack自动安装。

操作系统：CentOS7.2（其它系统同样支持）
硬件配置：4vCPU+8G Memory+20G磁盘

1.关闭并禁用防火墙：

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

2.关闭selinux：

# setenforce 0

编辑/etc/selinux/config文件内容，将SELINUX值enforcing改为disabled：

SELINUX=disabled

3.配置p版yum源

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

4.禁用掉无法使用的CentOS-QEMU-EV.repo源，可直接删除该源文件。

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

5.手动配置可用的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源或执行以下命令安装：

# 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源后安装applydeltarpm包，防止自动安装时报错。

# yum install deltarpm -y

8.安装packstack工具

# yum install openstack-packstack

9.Packstack一键安装：

# packstack --allinone

常见故障处理排查及使用方法
如下提到的处理方法，适用于以上三个版本的PackStack方式安装。
1.常见错误：

Testing if puppet apply is finished :192.168.20.200_controller.pp
安装过程卡在此步骤没有任何反应。
分析：网络正常情况下此过程不超过30分钟。时间过长时，需要确认关闭NetworkManger、selinux、firewalld。还可检查硬件配置，建议4核CPU+8GB内存或更高配置。还无法解决后可添加至2个网卡、2个磁盘。

2.PackStack日志信息：

PackStack安装过程中的日志在 /var/tmp/packstack/ 目录中。无法解决问题时可查看该目录下相关日志信息。

3.常见认证文件：

执行packstack --allinone安装命令后，会在执行目录下生成
keystonerc_admin 、keystonerc_demo、packstack-answers-20181025-111102.txt三个文件。可查看keystonerc_admin文件内容获取登录Dashboard的用户名和密码。安装过程的相关配置信息记录在packstack-answers-20181025-111102.txt文件中。执行OpenStack操作命令前需要执行source keystonerc_admin命令h获取管理员认证。

4.安装成功过程记录：

[root@newton ~]# packstack --allinone

以上过程为安装成功时的全部信息，由于没有关闭NetworkManager导致出现警告信息，需要手动执行如下命令关闭NetworkManager：

systemctl disable NetworkManger 
systemctl stop NetworkManager
