先电云计算Iaas云平台 compute节点搭建过程
------------------------修改网卡地址--------------------------------vi /etc/sysconfig/network-scripts/ifcfg-eth0
------------------------修改Hosts-----------------------
vi /etc/hosts
------------------------重启网络------------------------------------
systemctl restart network.service
------------------------关闭防火墙----------------------------------
systemctl stop firewalld.service
systemctl enable firewalld.service
setenforce 0  
----------------------------移除默认yum文件--------------------------------
mv /etc/yum.repos.d/* /opt/
----------------------------配置yum文件-------------------------------
vi /etc/yum.repos.d/local.repos
-----添加---------（注：具体的yum源根据真实环境controller节点地址的配置）
[centos]
name=centos
baseurl=ftp://192.168.100.100/centos7
gpgcheck=0
enabled=1
[openstack]
name=Openstack
baseurl=ftp://192.168.100.100/iaas-repo
gpgcheck=0
enabled=1

-----------安装openstack包--------------(等controller的vsftp安装好后执行）(iaas-install.pre.sh)
yum -y install openstack-utils open -selinux python-openstackclient
yum upgrade----------------安装脚本文件和配置文件------------------------yum -y install iaas-xiandian

-------------------注释openrc---------------------
vi /etc/xiandian/openrc.sh
-----修改--------

---------------同步时钟------------------
yum -y install ntpdate
ntpdate controller
systemctl start ntpdate.service
systemctl enable ntpdate.service
------------运行相应的脚本文件------------------
iaas-install-nova-compute.sh
iaas-install-neutron-compute.sh
iaas-install-neutron-compute-flat.sh 
or(二选一）
iaas-install-neutron-compute-gre.sh
iaas-install-cinder-compute.sh
