環境準備

我這裏用workstation建立了一個虛擬機，安裝centos7.5 mini系統，這臺虛擬機上有兩張網卡，一張作openstack管理網，一張作爲虛擬機的業務網卡。
我用來測試的VM配置是4C,8G,100G
若是想運行ubuntu cloud images的話最好是8C,16G,100G的配置,固然~~若是你用cirros的話那就隨意咯！
基本信息以下

必定記得給虛機作個快照，必定記得給虛機作個快照，必定記得給虛機作個快照。

pull鏡像並部署

kolla-ansible prechecks
kolla-ansible pull
kolla-ansible deploy
kolla-ansible post-deploy
pip install --ignore-installed  ipaddress PyYAML
pip install python-openstackclient

[option]可選執行
若是安裝python-openstackclient出現錯誤能夠臨時指定pip源來從新執行python-openstackclient的安裝，能夠試下下面的命令
pip install -i https://pypi.mirrors.ustc.edu.cn/simple/ python-openstackclient
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple python-openstackclient

[option]可選執行
若是想安裝其餘的client，請執行如下命令
pip install python-PROJECTclient
請把PROJECT換成cinder或者glance等等等等等等

因爲錯誤的出現，可能須要屢次的部署，而有些錯誤從新部署是不會進行修正的，因此須要將整個環境進行清理:

tools/cleanup-containers                #可用於從系統中移除部署的容器
tools/cleanup-host                      #可用於移除因爲殘餘網絡變化引起的docker啓動的neutron-agents主機
tools/cleanup-images                    #可用於從本地緩存中移除全部的docker image

登陸配置OpenStack

此時就能夠訪問本身的IP地址了
使用瀏覽器訪問Dashboard，我這裏地址就是192.168.6.50
用戶名爲admin密碼爲password
1.登陸以後須要本身建立實例類型

2.本身建立網絡、子網、路由器
3.導入鏡像
能夠參考https://www.cnblogs.com/tcicy/p/10306306.html
4.建立實例
目前還有個問題，就是我還不知道怎麼給虛擬機分配浮動IP地址，沒有浮動IP地址的話就沒有辦法讓外部網絡設備直接訪問ubuntu cloud images instance 18.04.
不過通過這個過程，已經搭建完成OpenStack，比起之前的版原本說那但是至關的簡單簡潔了。
後面開始大家的表演。
若是有問題能夠直接網站內消息或者tcicy#126.com
順便說下Markdown 真香
