環境
- VMware CentOS 7
- CPU核心數：4
- RAM：10G
- DISK：45G
準備
關於這個配置，是我在試了一天得出的結論，一直卡着
192.168.1.106_controller.pp:
Testing if puppet apply is finished: 192.168.1.106_controller.pp [ | ]
我也不知道他一直在測試什麼，只是卡着，也不報錯。
各種搜，顯示關了防火牆，關了selinux，關了networkmanager。然後又查出可能是配置不夠，因爲自動安裝比手動更喫配置，我原先配置是4G2核，升級到4核6G，還是卡，然後升級到4核8G，網上有人說他加到了16G，我一共就16G也沒辦法試，就8G再看看，這時候等了一會發現他test成功了。
那麼大概就是，這個卡着的原因就是因爲內存不夠。
但是最後，我又裝了一次，是10G RAM，45G 硬盤，因爲8G太卡了，火狐一打開內存就不夠用，會閃退，8不夠
然後開始配置吧
同時可以在安裝的時候通過packstack配置相應的配置文件，自行配置需要安裝的模塊、賬戶密碼等安裝參數。
把網卡改成橋接模式，修改配置文件/etc/sysconfig/network-scripts/ifcfg-eno16777736，DNS要設置好，不然解析不了域名了。GATEWAY可以通過netstat -rn查看。
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=eno16777736
UUID=acd2af84-eb36-4ffe-8a43-8528e2d8e87c
DEVICE=eno16777736
ONBOOT=yes
PEERDNS=yes
PEERROUTES=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPADDR=192.168.1.106
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=114.114.114.114
DNS2=8.8.4.4
重啓網絡
systemctl restart network
這裏我換源了，換阿里源
先執行mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup，備份一下原來的源，不過一般沒啥用，mv或者cp都能用，後面的目標路徑也可以直接寫一個文件名，即當前路徑。
下載阿里源，這裏每個版本的源地址不一樣，版本看好。
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
重新生成緩存
yum clean all && yum makecache
配置一下時間同步服務，使用chrony。
yum install -y chrony
編輯配置文件/etc/chrony.conf
添加
restrict 192.168.1.106
#server *ntp.ubuntu.com* iburst
server 127.127.1.0 prefer
然後修改主機名
hostname set-hostname controller
改Hostsetc/Hosts添加192.168.1.106 controller。
可以重啓一下。
關閉防火牆和SELINUX和Network，通過getenforce查看selinux狀態（enforcing試開啓disable是關閉）。通過systemctl status firewalld查看防火牆狀態。
執行systemctl stop firewalld && systemctl disable firewalld關閉防火牆。
編輯/etc/selinux/config的SELINUX改爲disabled。
執行systemctl stop NetworkManager && systemctl disable NetworkManager。
重啓網絡network服務。順便重啓一下。
然後依次執行下面命令就可以完成安裝了
yum install -y centos-release-openstack-rocky
yum -y update
yum install -y openstack-packstack
這裏停一下，不要急着執行下面的命令，這個命令是allinone模式，會全部安裝，可能有一些不需要的之類模塊。
packstack --allinone
先生成配置文件，這裏的answer.ini文件隨意，什麼default.conf都行
packstack --gen-answer-file=answer.ini
然後編輯這個answer.ini文件，可以自行設置一些安裝參數，比如如果不想安裝某個模塊，讓他等於n就行了，編輯完保存退出。
然後需要再次換一下源,編輯/etc/yum.repos.d/CentOS-OpenStack-rocky.repo，修改一下baseurl，換成阿里的https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-rocky/，你可以按照你自己的OpenStack版本選一下。
[centos-openstack-rocky]
name=CentOS-7 - OpenStack rocky
baseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-rocky/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Cloud
exclude=sip,PyQt4
此時安裝可能還會提示qemu版本過低，再配置一個源/etc/yum.repos.d/CentOS-QEMU-EV.repo，也是編輯一下baseurl：https://mirrors.aliyun.com/centos/7/virt/x86_64/kvm-common/。
[centos-qemu-ev]
name=CentOS-$releasever - QEMU EV
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=virt-kvm-common
#baseurl=http://mirror.centos.org/$contentdir/$releasever/virt/$basearch/kvm-common/
baseurl=https://mirrors.aliyun.com/centos/7/virt/x86_64/kvm-common/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Virtualization
配置好了answer應答文件以後就得執行下面的命令通過這個配置文件進行安裝
packstack --answer-file=answer.ini
這時候就應該正常了。

安裝完成
裝完以後，在~目錄下有幾個文件，此時由兩個用戶，一個是admin，另一個是demo。密碼分別在keystone_admin和keystoneec_demo裏面，如admin裏面是這樣，似乎就是環境變量。
unset OS_SERVICE_TOKEN
export OS_USERNAME=admin
export OS_PASSWORD='19b0a14315174976'
export OS_REGION_NAME=RegionOne
export OS_AUTH_URL=http://192.168.1.106:5000/v3
export PS1='[\u@\h \W(keystone_admin)]\$ '
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3
執行source keystonerc_admin導入admin的環境變量，執行openstack user list可以測試一下能不能用，可以顯示用戶說明正常了。
然後再測試一下登錄dashboard，登錄192.168.1.106/dashboard
輸入用戶名密碼登錄
admin
19b0a14315174976
修改一下語言和TimeZone。
