本人在做安装openstackpackstack 安装先设置好的应答文件answer.txt，# packstack --answer-file answer.txt出现以上错误，查看报错日志，和journalctl -xe journalctl -fsystemctl 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192.168.4.1192.168.4.2 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4.14.2分别与vh01.ldc.cnvh02.ldc.cn对应，然后删除answer.txt
生成自动应答文件，并编辑
#packstack --gen-answer-file answer.txt
#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
# mkdir /var/ftp/rhel7.2
# mkdir /var/ftp/osp8
2）挂载光盘镜像到软件包目录
# 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
# mount -a
3）创建rhel7 源配置文件：
# vim /etc/yum.repos.d/server.repo
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
# mkdir bin; cd bin
# 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
# bash mkrepo.sh
# 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
# yuminstall -y bind
# vim/etc/named.conf
listen-on port 53 { any; };
allow-query { any; };
# vim/etc/named.rfc1912.zones
zone "ldc.cn"IN {
type master;
file "ldc.cn.zone";
allow-update { none; };
};
# 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.$
# chmod 640/var/named/ldc.cn.zone
# chgrpnamed /var/named/ldc.cn.zone
# systemctlstart named; systemctl enable named
检查语法
#named-checkconf /etc/named.rfc1912.zones
#named-checkzone ldc.cn /var/named/ldc.cn.zone
# nslookupvh201.ldc.cn
NTP：网络时间协议
# yum install-y ntp
# 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
# systemctlstart ntpd; systemctl enable ntpd
在vh02上同步时间
# date -s"2017-08-21 12:00:00"
# ntpdate192.168.4.1
配置openstack
1、为vh02配置IP地址
eth0: 192.168.4.2/24dns: 192.168.4.1
eth1: 192.168.2.2/24
2、关闭NetworkManager服务
# systemctlstop NetworkManager
# systemctldisable NetworkManager
3、创建名为cinder-volumes的卷组，用于提供云硬盘
# pvcreate/dev/vdb
# vgcreatecinder-volumes /dev/vdb
# vgs
4、导入rabbitmq的签名信息（如果连接互联网，可跳过）
#rpm --import rabbitmq-signing-key-public.asc
5、安装光盘上不存在的依赖包
# yuminstall -y *rpm
-----------------------------------------
-----------------------------------------
6、安装packstack
# yuminstall -y openstack-packstack
7、生成自动应答文件，并编辑
# packstack--gen-answer-file answer.txt
# 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
# 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
# cd/etc/sysconfig/network-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
# vim ifcfg-eth0
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=br-ex
BOOTPROTO=none
NAME=eth0
DEVICE=eth0
ONBOOT=yes
# systemctl restart network
