1. install minimal CentOS, and then:
cat << EOF > /etc/resolv.conf
nameserver 8.8.8.8
nameserver 114.114.114.114
EOF

yum install wget -y
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
#wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/epel-7.repo
#wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo

# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.

2.prepare installation:
#yum install epel-release -y
yum clean all
yum makecache
yum update -y

systemctl disable firewalld
systemctl stop firewalld
systemctl disable NetworkManager
systemctl stop NetworkManager
systemctl enable network
systemctl start network

yum install -y centos-release-openstack-newton
yum update -y
yum install -y openstack-packstack

3.配置免密:

cat << EOF >> .ssh/authorized_keys
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCmIAI4JjtlSBnrbbemIacc56M0v8m7nz/kcsK8oJwDrlMGKT42/u8rDA3DtarvLl9PDtP89P1jxzBcS87uZpnQcU6Pf3jq8OkNXA1R1yZozCmpaIt9bbPoO+hRacV2EF+WeJ/y/DM45J6tOxDCkjeBMFwBxE95OaxE/gBhdt5V1lTrvQ3nji7B5JVx28I2+DJpcNIDtKrI8fWiD58QIl95ZvGkh4NXzgmBL4wuzfIeMQ4D8eFy844t/I2IOT6BkTdBMqu3GBm//+gAuL0qsicrnw2yc+oBkYauomtonRzodFu4Qsp8C6gfJqRtDFHzaGiQivtKPG/lE9BAo+
EOF

4.配置hostname

cat << EOF >> /etc/hosts
10.xx.31 queens-ct
10.xx.32 queens-cp1
10.xx.33 queens-cp2
EOF
10.xx.87 o-ctr-vlan
10.xx.88 o-compute-vlan
##
方法3：修改了/etc/sysconfig/network下的HOSTNAME后，然后使用hostname命令使其生效
[root@Test ~]# hostname DB-Server
##        
     
yum install screen
screen
packstack --gen-answer-file=answer-vlan.conf

5.answer file 配置及安装:

sed -i 's/^CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS.*/CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=extnet:br-ex,physnet1:br-vlan/' answer-vlan.conf
sed -i 's/^CONFIG_NEUTRON_OVS_BRIDGE_IFACES.*/CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth0,br-vlan:eth1/' answer-vlan.conf
