环境
- VMware CentOS 7
- CPU核心数：4
- RAM：10G
- DISK：45G
准备
关于这个配置，是我在试了一天得出的结论，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测试什么，只是卡着，也不报错。
各种搜，显示关了防火墙，关了selinux，关了networkmanager。然后又查出可能是配置不够，因为自动安装比手动更吃配置，我原先配置是4G2核，升级到4核6G，还是卡，然后升级到4核8G，网上有人说他加到了16G，我一共就16G也没办法试，就8G再看看，这时候等了一会发现他test成功了。
那么大概就是，这个卡着的原因就是因为内存不够。
但是最后，我又装了一次，是10G RAM，45G 硬盘，因为8G太卡了，火狐一打开内存就不够用，会闪退，8不够
然后开始配置吧
同时可以在安装的时候通过packstack配置相应的配置文件，自行配置需要安装的模块、账户密码等安装参数。
把网卡改成桥接模式，修改配置文件/etc/sysconfig/network-scripts/ifcfg-eno16777736，DNS要设置好，不然解析不了域名了。GATEWAY可以通过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
重启网络
systemctl restart network
这里我换源了，换阿里源
先执行mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup，备份一下原来的源，不过一般没啥用，mv或者cp都能用，后面的目标路径也可以直接写一个文件名，即当前路径。
下载阿里源，这里每个版本的源地址不一样，版本看好。
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
重新生成缓存
yum clean all && yum makecache
配置一下时间同步服务，使用chrony。
yum install -y chrony
编辑配置文件/etc/chrony.conf
添加
restrict 192.168.1.106
#server *ntp.ubuntu.com* iburst
server 127.127.1.0 prefer
然后修改主机名
hostname set-hostname controller
改Hostsetc/Hosts添加192.168.1.106 controller。
可以重启一下。
关闭防火墙和SELINUX和Network，通过getenforce查看selinux状态（enforcing试开启disable是关闭）。通过systemctl status firewalld查看防火墙状态。
执行systemctl stop firewalld && systemctl disable firewalld关闭防火墙。
编辑/etc/selinux/config的SELINUX改为disabled。
执行systemctl stop NetworkManager && systemctl disable NetworkManager。
重启网络network服务。顺便重启一下。
然后依次执行下面命令就可以完成安装了
yum install -y centos-release-openstack-rocky
yum -y update
yum install -y openstack-packstack
这里停一下，不要急着执行下面的命令，这个命令是allinone模式，会全部安装，可能有一些不需要的之类模块。
packstack --allinone
先生成配置文件，这里的answer.ini文件随意，什么default.conf都行
packstack --gen-answer-file=answer.ini
然后编辑这个answer.ini文件，可以自行设置一些安装参数，比如如果不想安装某个模块，让他等于n就行了，编辑完保存退出。
然后需要再次换一下源,编辑/etc/yum.repos.d/CentOS-OpenStack-rocky.repo，修改一下baseurl，换成阿里的https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-rocky/，你可以按照你自己的OpenStack版本选一下。
[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
此时安装可能还会提示qemu版本过低，再配置一个源/etc/yum.repos.d/CentOS-QEMU-EV.repo，也是编辑一下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应答文件以后就得执行下面的命令通过这个配置文件进行安装
packstack --answer-file=answer.ini
这时候就应该正常了。

安装完成
装完以后，在~目录下有几个文件，此时由两个用户，一个是admin，另一个是demo。密码分别在keystone_admin和keystoneec_demo里面，如admin里面是这样，似乎就是环境变量。
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
执行source keystonerc_admin导入admin的环境变量，执行openstack user list可以测试一下能不能用，可以显示用户说明正常了。
然后再测试一下登录dashboard，登录192.168.1.106/dashboard
输入用户名密码登录
admin
19b0a14315174976
修改一下语言和TimeZone。
