Compute： 内存 6G+ 处理器4个 + 硬盘（sda）100G + 硬盘（sdb 50G）+ 硬盘（sdc 50G）+ 网卡1（仅主机192.168.100.20）+ 网卡2（NAT 192.168.200.20）
3.私有云部署：注释：
1.此处可先不编写hosts文件 + 关闭selinux + 注释swap分区
2.因为在下面执行 iaas-pre-host.sh 脚本时，这些操作都会执行。
3.下面关闭防火墙的操作是为了ftp共享时compute可访问controller节点
以下操作看清主机名分别在哪个主机执行：
3.1修改主机名hostnamectl set-hostname controller hostnamectl set-hostname compute systemctl stop firewalld systemctl disable firewalld setenforce 03.2挂载镜像文件：

项目–网络–安全组–管理规则----删除所有规则
管理员–网络–网络–创建网络
项目–网络–路由
注：在虚拟机中网络模式默认是vxlan，服务器上可改用vlan
因为服务器连接了交换机，会设置接口模式为trunk，放行vlan，虚拟机中无法进行此项操作
在服务器中创建vlan网络需修改配置文件：
[root@controller ~]# vim /etc/neutron/plugins/ml2/ml2_conf.ini [ml2] type_drivers = flat,vlan,vxlan tenant_network_types = vlan [root@controller ~]# systemctl restart neutron*
项目–网络–创建网络
5.6将两个网络关联起来：
项目–网络–路由–router–接口–增加接口
查看网络拓扑
1.上传测试镜像：
[root@controller ~]# source /etc/keystone/admin-openrc.sh [root@controller ~]# glance image-create --name cirros --disk-format=qcow2 --container-format=bare --visibility=public --file cirros-0.4.0-x86_64-disk.img
2.创建云主机类型：
3.创建实例：
项目–资源管理–云主机–创建云主机
4.绑定浮动ip：
5.测试success！！
