OpenStack入门修炼之实战
1.给两台虚拟机增加网卡，使用仅主机模式，网段为：192.168.57.0/242.修改两台主机网卡配置
# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1
# vim /etc/sysconfig/network-scripts/ifcfg-eth1
TYPE=Ethernet
BOOTPROTO=static
NAME=eth1
DEVICE=eth1
ONBOOT=yes
IPADDR=192.168.57.11
NETMASK=255.255.255.0
# systemctl restart network
# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1
# vim /etc/sysconfig/network-scripts/ifcfg-eth1
TYPE=Ethernet
BOOTPROTO=static
NAME=eth1
DEVICE=eth1
ONBOOT=yes
IPADDR=192.168.57.12
NETMASK=255.255.255.0
# systemctl restart network
3.修改桥接网络配置
# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
physical_interface_mappings = public:eth0,internal:eth1
public:公网 internal:私网
# source admin-openstack
# openstack endpoint list
4.修改ml2的配置
# vim /etc/neutron/plugins/ml2/ml2_conf.ini
flat_network：单一扁平网络
flat_network = public,internal
# systemctl restart neutron-server
# systemctl restart neutron-linuxbridge-agent
5.计算节点：linux-node2一样配置/etc/neutron/plugins/ml2/linuxbridge_agent.ini
physical_interface_mappings = public:eth0,internal:eth1
# systemctl restart neutron-linuxbridge-agent
6.创建网络
# source admin-openstack
# openstack network create --share \
--provider-physical-network internal \
--provider-network-type flat internal<--网络名称
# openstack subnet create --network internal \
--allocation-pool start=192.168.57.100,end=192.168.57.200
--dns-nameserver 192.168.56.2 --gateway 192.168.57.2 \
--subnet-range 192.168.57.0/24 internal-subnet
7.dashboard查看并创建云主机
在创建云主机时即可选择网络，如图：
实现阿里云的FLAT网络（经典网络）一个公网ip，一个私网ip，如图：
