官方詳細過程文檔：https://docs.openstack.org/install-guide/index.html
(UPDATED: 2018-03-04 07:07) 要仔細閱讀文檔，，，

由於一直之前安裝出現各種問題，安裝前永久關閉了系統的selinux和firewalld。

問題以及文檔描述不夠清晰的第三方參考
/etc/httpd/conf.d/00-nova-placement-api.conf:文件的修改

安裝Dashboard服務後，再額外修改一處地方

Ensure your Linux operating system kernel supports network bridge filters

一些可能會混淆的地方
共兩臺虛擬主機的最小化安裝Controller node 和 Compute node
每個虛擬機配置網口時有兩個網口：

Management管理網口 和 Provider networks服務網口

安裝包信息參考
yum upgrade

            both controller and compute:    yum install chrony centos-release-openstack-xxx python-openstackclient openstack-selinux openstack-neutron openstack-neutron-linuxbridge ebtables

           only ontroller:  yum install rabbitmq-server memcached python-memcached etcd openstack-keystone httpd mod_wsgi openstack-glance   python2-PyMySQL
    (tar安裝包安裝mysql,並設置好root密碼)
    yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement-api
    yum install  openstack-neutron-ml2
    yum install openstack-dashboard

             only compute:  yum install ipset 
        yum install openstack-nova-compute

參考官方文檔
https://docs.openstack.org/install-guide/environment.html

1. 各個節點主機名不能相同，（也避免下劃線吧如：and_node1）

2. 設置密碼避免使用@ （如：abc@233）

3. 安裝glance時有省略（To create the database, complete these steps:），就是要先創建數據庫glance（create database glance;）

4. CentOS7.4 安裝MariaDB無法啓動，改爲MySQL官方最新版繼續了
