1.关闭NetworkManager
systemctl disable NetworkManager
systemctl stop NetworkManager
2.更换yum源
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
3.配置时间同步
yum -y install ntpdate
ntpdate ntp.aliyun.com >>/var/log/ntpdate.log
ntpdate ntp.aliyun.com
4.安装openstack的train源
yum -y install centos-release-openstack-train
yum install -y http://rdo.fedorapeople.org/rdo-release.rpm
5.生成安装openstack 配置文件
packstack --gen-answer-file /root/openstack-answer.txt
6.编写配置文件
CONFIG_HEAT_INSTALL=y # Heat openstack编排组件，这个安装
CONFIG_PROVISION_DEMO=n # 模板，不用生成
CONFIG_KEYSTONE_ADMIN_PW=Password #admin密码，修改个自己习惯的
CONFIG_NEUTRON_OVN_BRIDGE_IFACES=br-ex:ens33 # 重点，这个是将openstack 外网网卡绑定到centos网卡
CONFIG_NEUTRON_ML2_TYPE_DRIVERS=vlan,flat # openstack虚拟化网络为vlan
CONFIG_NEUTRON_ML2_TENANT_NETWORK_TYPES=vlan # openstack虚拟化网络为vlan
..............
目前我实验可加安装（可选，在最小化安装上添加）
..............
CONFIG_PANKO_INSTALL=y #openstack panko组件
CONFIG_SAHARA_INSTALL=y #openstack sahara组件
CONFIG_TROVE_INSTALL=y #openstack trove组件
7.安装openstack
