openstack 安裝步驟：
環境準備：
系統：centos7 x86_64
controller 2c+6g+40g 192.168.147.50 可以nat上網
compute 1c+4g+40g 192.168.147.60 可以nat上網
neutron 1c+2g+20g 192.168.147.70 可以nat上網

關閉selinux:
cat /etc/sysconfig/selinux
SELINUX=disabled
SELINUXTYPE=targeted

配置hostname：
192.168.147.50 openstack-controller openstack-controller.com
192.168.147.60 openstack-compute openstack-compute.com
192.168.147.70 openstack-neutron openstack-neutron.com
關閉防火牆：
systemctl disable firewalld
重啓
reboot
基礎軟件包：
yum install openssl openssl-devel net-tools vim wget -y

時間同步：
控制節點：
yum install chrony -y

配置ntp：
vi /etc/chrony.conf
加入：
server time.windows.com iburst
allow 192.168.147.0/24
啓動服務：
systemctl enable chronyd.service
systemctl start chronyd.service

其他節點：

yum install chrony -y

配置ntp：
vi /etc/chrony.conf
加入：
server time.windows.com iburst
server 192.168.147.50 iburst
啓動服務：
systemctl enable chronyd.service
systemctl start chronyd.service

所有節點：
同步時鐘：
chronyc sources
確保所以的時間都是同步的。
使用timedatectl status查看：
[root@openstack-compute ~]# timedatectl status
Local time: 一 2018-03-12 23:14:13 CST
Universal time: 一 2018-03-12 15:14:13 UTC
RTC time: 一 2018-03-12 15:14:13
Time zone: Asia/Shanghai (CST, +0800)
NTP enabled: yes
NTP synchronized: yes
RTC in local TZ: no
DST active: n/a

所有節點：安裝openstack的yum 源：
yum install centos-release-openstack-queens -y
yum upgrade -y 更新yum源
安裝opentack client的python包：
yum install python-openstackclient -y
如果系統關閉了selinux可以不用安裝這個包：
yum install openstack-selinux -y

控制節點安裝mysql:
yum install mariadb mariadb-server python2-PyMySQL -y

vi /etc/my.cnf
[mysqld]
bind-address = 192.168.147.50

default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

啓動服務：#
systemctl enable mariadb.service
systemctl start mariadb.service
修改密碼：
mysql_secure_installation

安裝rabbitmq：
yum install rabbitmq-server -y
啓動服務：
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
創建用戶和授權：
rabbitmqctl add_user openstack openstack
rabbitmqctl set_permissions openstack "." "." ".*"
將openstack加入administrator組要不然web界面無法登陸
rabbitmqctl set_user_tags openstack administrator
啓動web界面插件：
rabbitmq-plugins enable rabbitmq_management
重啓rabbitmq
systemctl restart rabbitmq-server

web界面登陸測試：
http://192.168.147.50:15672 使用openstack登陸即可

安裝memcache：
yum install memcached python-memcached -y
修改memecahe的配置文件 /etc/sysconfig/memcached ：
OPTIONS="-l 127.0.0.1,::1,openstack-controller"

啓動：
systemctl enable memcached.service
systemctl start memcached.service

檢查一下memcache端口：
[root@openstack-controller ~]# netstat -anltp|grep memcache
tcp 0 0 192.168.147.50:11211 0.0.0.0: LISTEN 56532/memcached
tcp 0 0 127.0.0.1:11211 0.0.0.0: LISTEN 56532/memcached
tcp6 0 0 ::1:11211 :::* LISTEN 56532/memcached

安裝etcd:
yum install etcd -y
編輯配置文件：
vi /etc/etcd/etcd.conf
#[Member]
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_PEER_URLS="http://192.168.147.50:2380"

ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"
ETCD_INITIAL_CLUSTER_STATE="new"

啓動服務：
systemctl enable etcd
systemctl start etcd

keystone安裝：
創建數據庫：
mysql -uroot -padm123
創建keystone數據庫並授權：
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone. TO 'keystone'@'localhost' \
IDENTIFIED BY 'keystone';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY 'keystone';

安裝keystone的包：
yum install openstack-keystone httpd mod_wsgi -y

修改keystone的配置文件 /etc/keystone/keystone.conf：
1.數據庫連接：
[database]
connection = mysql+pymysql://keystone:[email protected]/keystone
2.令牌提供者
[token]
provider = fernet
3.同步數據庫一定要在keystone用戶下：
su -s /bin/sh -c "keystone-manage db_sync" keystone
4.初始化臨牌倉庫：
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

5.定義管理服務：
keystone-manage bootstrap --bootstrap-password keystone \
--bootstrap-admin-url http://192.168.147.50:35357/v3/ \
--bootstrap-internal-url http://192.168.147.50:5000/v3/ \
--bootstrap-public-url http://192.168.147.50:5000/v3/ \
--bootstrap-region-id RegionOne

小插曲：
由於按照官方文檔 http://controller:35357/v3/ 但是我的主機名是openstac-controller，所以會報錯。
這個時候keystone-manage 沒有刪除命令，你修改成正確的命令也不行，需要修改數據庫的endpoint表
use keystone；
update endpoint set url="http://192.168.147.50:5000/v3/" where id="xxx";

update endpoint set url="http://192.168.147.50:35357/v3/" where id="xxx";
6.配置http:
vim /etc/httpd/conf/httpd.conf
ServerName openstack-controller
配置wsgi模塊軟件連接：
ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

啓動httpd服務：
systemctl enable httpd.service
systemctl start httpd.service

創建admin環境變量腳本：

當您添加新的計算節點時，您必須在控制器節點上運行nova管理cellv2發現主機來註冊這些新的計算節點。或者，您可以在/etc/nov/nova.conf中設置適當的間隔

su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

或者：
修改nova.conf修改時間間隔:

安裝實例的時候注意：
這個坑我用了一下午的時間解決：
centos7.4 會出現你創建虛擬機之後，boot界面，但是可以獲取到ip。不能登錄，不能查看界面，nova的console日誌也是爲空。將libvirt的 virt_type改成qemu也不好使。這個是內核的關係。所以在安裝了openstack的源之後不要只想yum update 要不然創建了虛擬機使用不了。
更換成centos7.2 可以圓滿解決這個問題
