【十二】Openstack-实现内网通信及通过nova命令创建虚拟机并分配自定义IP
配置Openstack 内网访问
#编辑配置文件ml2_conf.ini,定义一个内部网络-internal
【controller节点上都要配置】
vim /etc/neutron/plugins/ml2/ml2_conf.ini
flat_networks = external,internal
#编辑配置文件linuxbridge_agent.ini，定义个内部接口映射关系绑定到eth1网卡上
【controller、node上的都要进行修改】
vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
physical_interface_mappings = external:eth0,internal:eth1
#控制节点当前全部配置
#重启neutron服务
【controller】
systemctl restart neutron-server.service \
neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
neutron-metadata-agent.service
【node】
systemctl restart neutron-linuxbridge-agent.service
#创建内部网络
[root@openstack-controller2 ~]# neutron net-create --shared --provider:physical_network internal --provider:network_type flat internal-net
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

#验证内网 - 网络是否正常
#先自定义centos7镜像 添加两块网卡-前提 宿主机要2块网卡 并且做过bridge桥接
#
#将配置好的虚拟机 关机 传到openstack 服务器上 上传到glance中

制作自定义镜像 添加两块网卡
配置好的 模板centos7镜像中的 网卡信息
上传的镜像
创建实例
登陆控制台查看-两块网卡-网络是否都正常
使用controller节点登陆 实例 -由于之前已经把公钥添加进 模板centos了 登陆无需密码
创建主机聚合
使用nova 创建虚拟机
