openstack命令创建云主机实例
@
前言
简单创建云主机实例只需要上传一个测试镜像、创建一张外网卡、创建一个实例类型、修改安全组规则即可
注：这里的两条命令是为了解决 虚拟机 环境下的 QEMU模拟器错误 导致云主机无法使用的问题，旧版本先电v2.2不存在此问题，真实服务器请忽略。
## 更改配置文件并重启 nova-compute 服务
[root@compute ~]# crudini --set /etc/nova/nova.conf libvirt virt_type qemu
[root@compute ~]# systemctl restart openstack-nova-compute
上传centos镜像
上传一个centos镜像，还可以设置最小启动磁盘与内存等，可以参考文档
ages]# openstack image create --disk-format qcow2 --container-format bare --file ./CentOS_7.2_x86_64_XD.qcow2 centos
[root@controller images]# openstack image create --disk-format qcow2 --container-format bare --file ./CentOS_7.2_x86_64_XD.qcow2 centos

创建实例
创建一个名为test0的实例
openstack flavor create --disk 10 --ram 1024 --vcpu 2 --id 99999 test0

创建外网卡
注：若使用 虚拟机 搭建，外部网络类型请选择Flat；若使用 服务器 搭建，外部网络类型请选择VLAN；注意不要重复执行命令，二选一执行。
openstack network create --provider-network-type vlan --provider-physical-network provider network-vlan --provider-segment 200
[root@controller ~]# openstack network create --provider-network-type vlan --provider-physical-network provider ext-net --provider-segment 200
