1、 必须双网卡，虚拟机一个用NAT模式，一个用仅主机模式，虚拟机最小安装，
????? 其中一台做controller节点，另一台做compte节点，但是compute的/目录必须大于controller节点
????? 装系统的时候设置自定义磁盘——》帮我选择-->/home 移除 把 /扩展 “/”小的做controller节点
????? 安装、设置密码即可
注：net模式的网卡不用，用仅主机的模式网卡用
?????? #SecureCR 连接
双桥接网卡实现过程中注意事项：
1.双桥接模式openstack创建的路由器接口内网关 要与外部网络((ext-net))子网内(int-net)固定网关一致
2、进系统第一步：通过ip a 命令查看网卡
?? ??????????? 改IP? （两台机器）
?? ?[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33
?? ?BOOTPROTO=static
?? ?ONBOOT=yes
?? ?IPADDR=192.168.100.10
?? ?NETMASK=255.255.255.0
?? ?[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33
?? ?
???? 第二步：改主机名? （两台机器）
?? ?[root@localhost ~]# hostnamectl set-hostname controller?? #controller主机名
?? ?[root@localhost ~]# hostnamectl set-hostname compute
???? 第三步:关闭防火墙和selinux? （两台机器）
?? ?[root@controller ~]# systemctl stop firewalld???????? ?
?? ?[root@controller ~]# systemctl stop firewalld???? ?
?? ?[root@controller ~]# vi /etc/sysconfig/selinux
?? ?SELINUX=permissive
?? ?[root@controller ~]# setenforce 0
???? 第四步：用CRT传镜像，iaas平台所需镜像为：Centos7_1804 、chinaskills_cloud_iaas.iso
?????? (以上镜像和软件可从此处获取：
链接：https://pan.baidu.com/s/1BxX12EeO6YdOddJkJmJoIQ
提取码：zmi3
)
???? 第五步：改主机映射：? （同一网段两个地址）
?? ?[root@controller ~]# vi /etc/hosts
?? ?192.168.100.10? controller
?? ?192.168.100.20? compute
?? ?[root@compute ~]# vi /etc/hosts
?? ?192.168.100.10? controller
?? ?192.168.100.20?? compute
???? 第六步：挂载镜像：将上传的镜像挂载到/opt目录下的自己建的目录上? ?
?? ?[root@controller ~]# mkdir /opt/centos
?? ?[root@controller ~]# mkdir /opt/iaas
?? ?[root@controller ~]# mount /CentOS-7-x86_64-DVD-1511.iso /opt/centos/
?? ???????? mount: /dev/loop0 is write-protected, mounting read-only
?? ?[root@controller ~]# mount /XianDian-IaaS-v2.2.iso /opt/iaas/
?? ??????? mount: /dev/loop1 is write-protected, mounting read-only
?? ?修改yum源?? #（1）
?? ?[root@controller ~]# mv /etc/yum.repos.d/CentOS-*?? /media/
?? ?[root@controller ~]#vi /etc/yum.repos.d/local.repo
?? ?[centos]
?? ?name=centos
?? ?baseurl=file:///opt/centos
?? ?gpgcheck=0
?? ?enabled=1
?? ?[iaas]
?? ?name=iaas
?? ?baseurl=file:///opt/iaas/iaas-repo
?? ?gpgcheck=0
?? ?enabled=1
?? ?[root@controller ~]# yum clean all
?? ?[root@controller ~]# yum list
?? ?安装ftp服务
?? ?[root@controller ~]# yum install vsftpd
?? ?[root@controller ~]# vi /etc/vsftpd/vsftpd.conf
?? ?anon_root=/opt
?? ?[root@controller ~]# systemctl start vsftpd
?? ?
?????? ??? ?#（2）
?? ?[root@compute ~]# mv /etc/yum.repos.d/CentOS-* /media/
?? ?[root@compute ~]# cat /etc/yum.repos.d/ftp.repo
?? ?[centos]
?? ?name=centos
?? ?baseurl=ftp://controller/centos
?? ?gpgcheck=0
?? ?enabled=1
?? ?[iaas]
?? ?name=iaas
?? ?baseurl=ftp://controller/iaas/iaas-repo
?? ?gpgcheck=0
?? ?enabled=1
?? ?
第七步：两台主机安装iaas-xiandian 包
?? ?yum install iaas-xiandian
?? ?vi /etc/xiandian/openrc.sh
?? ?#注意keystone下有一个域名=demo;网卡名为第二块网卡名、去注释
?? ?scp /etc/xiandian/openrc.sh? root@compute:/etc/xiandian/
