本人在做安装openstack  packstack 安装先设置好的应答文件answer.txt，[iyunv@vh02 ~]# packstack --answer-file answer.txt  出现以上错误，查看报错日志，和journalctl -xe     journalctl -f  systemctl status rabbitmq-server.service 根据提示，大概出现在两个位置，一个是hosts ,hostname   另外一个是数据库mariadb上，错误提示无法启动rabbitmq-server这个服务。查阅大量的百度资料还是无法解决这个问题。  
经过反复推敲，现在已经找到问题所在原因：
1.因为本机的192.168.4.1  192.168.4.2 这个IP 已经被别的虚拟机占用，因此我就用vh01.ldc.cn：192.168.4.4
    vh02.ldc.cn ：192.168.4.5
这样来设置，错误就出现在这里，因为下面的vim/var/named/ldc.cn.zone中使用的是
$generate       1-9    vh0$    IN      A      192.168.4.$
$generate       10-254 vh$     IN      A      192.168.4.$
“$”这个变量 IP 是跟vh主机对应的，也就是说vh01 对应 192.168.4.1 我给忽略了，因此在安装过程中就会导致报错。
2.把虚拟IP 改为4.1  4.2  分别与vh01.ldc.cn  vh02.ldc.cn  对应，然后删除answer.txt
  生成自动应答文件，并编辑
[iyunv@vh02 ~]#packstack --gen-answer-file answer.txt

[iyunv@vh02 ~]#packstack --answer-file answer.txt
成功。。。。

以下是安装流程：

准备主机
vh01.ldc.cn ->提供DNS和NTP   
vh02.ldc.cn ->安装openstack  需要有额外添加虚拟硬盘
物理主机      ->提供yum源
实现此案例需要按照如下步骤进行。
步骤一：通过ftp 输出软件包
1）创建软件包目录
[iyunv@vh01~]# mkdir /var/ftp/rhel7.2
[iyunv@vh01~]# mkdir /var/ftp/osp8
2）挂载光盘镜像到软件包目录
[iyunv@vh01~]# vim /etc/fstab
/ISO/CentOS-7-x86_64-DVD-1511.iso/var/ftp/rhel7.2 iso9660 defaults 0 0
/ISO/RHEL7OSP-8.0-20160421-x86_64.iso/var/ftp/osp8 iso9660 defaults 0 0
[iyunv@vh01~]# mount -a
3）创建rhel7 源配置文件：
[iyunv@vh01~]# vim /etc/yum.repos.d/server.repo
[rhel7.2]
name=rhel7.2
baseurl=ftp://192.168.4.1/rhel7.2
enabled=1
gpgcheck=0
步骤二：通过脚本生成osp 仓库源配置文件
1）编写脚本
[iyunv@vh01~]# mkdir bin; cd bin
[iyunv@vh01bin]# vim mkrepo.sh
#!/bin/bash
cd /var/ftp/osp8
for folder in *
do
if [ -d $folder ]; then
cat << EOF >>/etc/yum.repos.d/osp8.repo
[$folder]
name=$folder
baseurl=ftp://192.168.4.1/osp8/$folder
enabled=1
gpgcheck=0
EOF
fi
done
2）生成配置文件并验证
[iyunv@vh01 bin]# bash mkrepo.sh
[iyunv@vh01 bin]# cat /etc/yum.repos.d/osp8.repo

以上OSP仓库搭建需要用到这个镜像里面的包，太大了自行百度下载
大小：3.3GB
RHEL7OSP-8.0-20160421-x86_64

需要用到这些rpms包：

libnetfilter_queue-1.0.2-1.el7.x86_64(1)
libnetfilter_queue-1.0.2-1.el7.x86_64


准备环境
1、在vh01上配置dns
[iyunv@vh01 ~]# yuminstall -y bind
[iyunv@vh01 ~]# vim/etc/named.conf
        listen-on port 53 { any; };
        allow-query     { any; };
[iyunv@vh01 ~]# vim/etc/named.rfc1912.zones
zone "ldc.cn"IN {
        type master;
        file "ldc.cn.zone";
        allow-update { none; };
};
[iyunv@vh01 ~]# vim/var/named/ldc.cn.zone
$TTL    86400
@       IN     SOA     vh01.ldc.cn.   root.ldc.cn. (
                                20170801
                                3H
                                15M
                                1W
                                1D )
        IN     NS      vh01
$generate       1-9    vh0$    IN      A      192.168.4.$
$generate       10-254 vh$     IN      A      192.168.4.$
[iyunv@vh01 ~]# chmod 640/var/named/ldc.cn.zone
[iyunv@vh01 ~]# chgrpnamed /var/named/ldc.cn.zone
[iyunv@vh01 ~]# systemctlstart named; systemctl enable named
检查语法
[iyunv@vh01 ~]#named-checkconf /etc/named.rfc1912.zones
[iyunv@vh01 ~]#named-checkzone ldc.cn /var/named/ldc.cn.zone
[iyunv@vh01 ~]# nslookupvh201.ldc.cn

NTP：网络时间协议
[iyunv@vh01 ~]# yum install-y ntp
[iyunv@vh01 ~]# vim/etc/ntp.conf
restrict 192.168.4.0 mask255.255.255.0 nomodify
server 127.127.1.0 iburst
fudge 127.127.1.0 stratum3
[iyunv@vh01 ~]# systemctlstart ntpd; systemctl enable ntpd
在vh02上同步时间
[iyunv@vh02 ~]# date -s"2017-08-21 12:00:00"
[iyunv@vh02 ~]# ntpdate192.168.4.1

配置openstack
1、为vh02配置IP地址
eth0: 192.168.4.2/24  dns: 192.168.4.1
eth1: 192.168.2.2/24
2、关闭NetworkManager服务
[iyunv@vh02 ~]# systemctlstop NetworkManager
[iyunv@vh02 ~]# systemctldisable NetworkManager
3、创建名为cinder-volumes的卷组，用于提供云硬盘
[iyunv@vh02 ~]# pvcreate/dev/vdb
[iyunv@vh02 ~]# vgcreatecinder-volumes /dev/vdb
[iyunv@vh02 ~]# vgs
4、导入rabbitmq的签名信息（如果连接互联网，可跳过）
[iyunv@vh02 openstack]#rpm --import rabbitmq-signing-key-public.asc
5、安装光盘上不存在的依赖包
[iyunv@vh02 rpms]# yuminstall -y *rpm
-----------------------------------------

-----------------------------------------
6、安装packstack
[iyunv@vh02 rpms]# yuminstall -y openstack-packstack
7、生成自动应答文件，并编辑
[iyunv@vh02 ~]# packstack--gen-answer-file answer.txt
[iyunv@vh02 ~]# vimanswer.txt
CONFIG_DEFAULT_PASSWORD=redhat
CONFIG_SWIFT_INSTALL=n
CONFIG_NTP_SERVERS=192.168.4.1
CONFIG_COMPUTE_HOSTS=192.168.4.2
CONFIG_KEYSTONE_ADMIN_PW=redhat
CONFIG_CINDER_VOLUMES_CREATE=n
CONFIG_NEUTRON_ML2_VXLAN_GROUP=239.1.1.2
CONFIG_NEUTRON_ML2_VNI_RANGES=1001:2000
CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-ex
CONFIG_NEUTRON_OVS_TUNNEL_IF=eth1
CONFIG_PROVISION_DEMO=n
8、安装openstack
[iyunv@vh02 ~]# packstack--answer-file answer.txt
9、配置虚拟网络，使得物理网卡成为虚拟交换机上的一个端口
[iyunv@vh02 ~]# cd/etc/sysconfig/network-scripts/
[iyunv@vh02network-scripts]# cp ifcfg-eth0 ifcfg-br-ex
TYPE=OVSBridge
BOOTPROTO=none
NAME=br-ex
DEVICE=br-ex
ONBOOT=yes
IPADDR=192.168.4.2
PREFIX=24
DNS1=192.168.4.1
DEVICETYPE=ovs
[iyunv@vh02network-scripts]# vim ifcfg-eth0
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=br-ex
BOOTPROTO=none
NAME=eth0
DEVICE=eth0
ONBOOT=yes
[iyunv@vh02 ~]# systemctl restart network
