G020-OP-INS-RHEL-02 RedHat OpenStack 发放云主机（命令行） _Openstack

但使书种多，会有岁稔时。这篇文章主要讲述G020-OP-INS-RHEL-02 RedHat OpenStack 发放云主机（命令行）相关的知识，希望能为你提供帮助。
1 您需要了解

本篇采用 OpenStack 命令行进行操作
模拟弹性公网 EIP 地址段规划：采用和控制节点、计算节点及 NTP 节点同一网段即可，如：192.168.45.0/24
模拟云主机私网 IP 地址段规划：自定义网段，如：192.168.100.0/24
RedHatOpenStack 环境可参考下方 G019 博文进行搭建
文章中所提到的 公网 或 外网 或 弹性IP 均为模拟网段，本环境特指 192.168.45.0/24
发放云主机所使用的测试镜像 cirros-0.5.2-x86_64-disk.img 可 点击这里 进行下载

2 环境配置 2.1 创建 BR-EX 虚拟交换机

创建 br-ex 网卡并修改如下

[root@controller ~]# cd /etc/sysconfig/network-scripts/ [root@controller network-scripts]# cp ifcfg-eno16777736 ifcfg-br-ex [root@controller network-scripts]# vim ifcfg-br-ex [root@controller network-scripts]# cat ifcfg-br-ex TYPE=OVSBridge BOOTPROTO=none DEFROUTE=yes NAME=br-ex UUID=c4fd661f-6ce8-4532-ad57-4653077fefa2 DEVICE=br-ex DEVICETYPE=ovs ONBOOT=yes DNS1=192.168.45.1 IPADDR=192.168.45.150 PREFIX=24 GATEWAY=192.168.45.1

原网卡内容修改如下

[root@controller network-scripts]# vim ifcfg-eno16777736 [root@controller network-scripts]# cat ifcfg-eno16777736 TYPE=OVSPort BOOTPROTO=none DEFROUTE=yes NAME=eno16777736 UUID=c4fd661f-6ce8-4532-ad57-4653077fefa2 DEVICE=eno16777736 DEVICETYPE=ovs OVS_BRIDGE=br-ex ONBOOT=yes

重启网络服务并查看 ovs

[root@controller network-scripts]# service network restart Restarting network (via systemctl):[OK] [root@controller network-scripts]# ovs-vsctl show

2.2 创建用户环境变量文件

[root@controller ~]# cp keystonerc_admin keystonerc_cloudcs [root@controller ~]# vim keystonerc_cloudcs [root@controller ~]# cat keystonerc_cloudcs export OS_USERNAME=cloudcs export OS_TENANT_NAME=cloud export OS_PASSWORD=redhat export OS_AUTH_URL=http://192.168.45.150:5000/v2.0/ export OS_REGION_NAME=WuHan export PS1=[\\u@\\h \\W(keystone_cloudcs)]\\$
