1.關閉NetworkManager

systemctl disable NetworkManager

systemctl stop NetworkManager

2.更換yum源

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

3.配置時間同步

yum -y install ntpdate

ntpdate ntp.aliyun.com >>/var/log/ntpdate.log

ntpdate ntp.aliyun.com

4.安裝openstack的train源

yum -y install centos-release-openstack-train

yum install -y http://rdo.fedorapeople.org/rdo-release.rpm

5.生成安裝openstack 配置檔案

packstack --gen-answer-file /root/openstack-answer.txt

6.編寫配置檔案

CONFIG_HEAT_INSTALL=y                    # Heat openstack編排元件，這個安裝

CONFIG_PROVISION_DEMO=n             # 模板，不用生成

CONFIG_KEYSTONE_ADMIN_PW=Password    #admin密碼，修改個自己習慣的

CONFIG_NEUTRON_OVN_BRIDGE_IFACES=br-ex:ens33    # 重點，這個是將openstack 外網網絡卡繫結到centos網絡卡

CONFIG_NEUTRON_ML2_TYPE_DRIVERS=vlan,flat    # openstack虛擬化網路為vlan

CONFIG_NEUTRON_ML2_TENANT_NETWORK_TYPES=vlan     # openstack虛擬化網路為vlan

..............

目前我實驗可加安裝（可選，在最小化安裝上新增）

..............

CONFIG_PANKO_INSTALL=y    #openstack panko元件

CONFIG_SAHARA_INSTALL=y    #openstack sahara元件

CONFIG_TROVE_INSTALL=y     #openstack trove元件
