安装train版yum源（每个节点都执行）

yum install centos-release-openstack-train -y

检查源是否包含[base][updates][extras][centosplus][cloud][virt]（每个节点都执行）

[base]

安装openstack-packstack工具（每个节点都执行）

yum install openstack-packstack -y

生成openstack应答文件

packstack --gen-answer-file=openstack.txt

修改openstack应答文件

[19:57 root@localhost ~]# vim openstack.txt
41 CONFIG_SWIFT_INSTALL=n  #y-n SWIFT是OpenStack的对象存储组件，默认是Y，在生产环境中一般是不装，所以改n
50 CONFIG_AODH_INSTALL=n   #y-n 不安装该服务
97 CONFIG_COMPUTE_HOSTS=192.168.100.106 #计算节点ip地址
795 CONFIG_NEUTRON_ML2_TYPE_DRIVERS=vxlan,flat
801 CONFIG_NEUTRON_ML2_TENANT_NETWORK_TYPES=vxlan
808 CONFIG_NEUTRON_ML2_MECHANISM_DRIVERS=openvswitch
813 CONFIG_NEUTRON_ML2_FLAT_NETWORKS=physnet1      #flat网络这边要设置物理网卡名字
840 CONFIG_NEUTRON_L2_AGENT=openvswitch            #L2网络的代理模式,也可选择linuxbridge
858 CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-ex    #这边要设置物理网卡的名字
869 CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth0          #这边br-ex:eth0是网络节点的nat网卡，到时候安装完毕之后IP地址会漂到这个上
1181 CONFIG_PROVISION_DEMO=n        #DEMO是OpenStack联网下载一个测试镜像，这边没联网。说以改成n

回退leatherman版本（每个节点都执行）

#不执行此步骤会故障报错
facter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file or directory

leatherman rpm包版本问题
[20:06 root@localhost ~/openstack]# yum list | grep leatherman
leatherman.x86_64                        1.10.0-1.el7                  @epel    
leatherman-devel.x86_64                  1.10.0-1.el7                  epel 

而facter需要1.3.0
[20:09 root@localhost ~/openstack]# facter -p
facter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file or directory

回退leatherman版本
yum downgrade leatherman -y

执行安装

packstack --answer-file=<file>
