OpenStack基于CentOS 6官方通用云镜像创建实例

1）下载CentOS 6官方通用云镜像(qcow2格式)

[root@controller images]# wget http://cloud.centos.org/centos/6/images/CentOS-6-x86_64-GenericCloud-1907.qcow2

2）上传镜像到Glance

[root@controller images]# source /etc/profile.d/openstack-admin.sh

[root@controller images]# glance image-create --name "CentOS-6-x86_64" --file CentOS-6-x86_64-GenericCloud-1907.qcow2 --disk-format qcow2 --container-format bare --visibility public

3）查看镜像列表

[root@controller images]# openstack image list

4）查看实例类型列表

[root@controller images]# openstack flavor list

5）创建虚拟机实例

# 查看网络ID

[root@controller images]# openstack network list

# 查看子网

[root@controller images]# neutron subnet-list

# 查看安全组列表

[root@controller images]# openstack security group list

# 查看安全组规则

[root@controller images]# openstack security group rule list

# 查看密钥列表

[root@controller images]# openstack keypair list

# net-id是上面查看到的网络ID

--flavor m1.small                # 指定实例类型名称

--image CentOS-6-x86_64        # 指定镜像名称

--nic net-id=ef834f96-e472-44b8-8dc4-de1bf44cd472 # 指定网络ID

--security-group c9042bd6-c484-4528-8e1b-d69684c8aaf6    # 指定安全组ID

--key-name ssh_key        # 指定密钥对名称

virtual-vm-Centos7        # 指定实例名称

[root@controller images]# openstack server create --flavor m1.small --image CentOS-6-x86_64 --nic net-id=ef834f96-e472-44b8-8dc4-de1bf44cd472 --security-group c9042bd6-c484-4528-8e1b-d69684c8aaf6 --key-name ssh_key virtual-vm-Centos6

6）查看虚拟机列表

[root@controller images]# openstack server list

7）查看网页VNC登录虚拟机方式

[root@controller images]# openstack console url show virtual-vm-Centos6

8）访问VNC

9）登录虚拟机

# 从控制节点SSH登录实例，Centos 6官方通用云镜像默认用户名为centos

# 从控制节点ping实例IP地址，测试是否可以ping通

[root@controller images]# ping -c 4 192.168.3.16

[root@controller images]# ssh centos@192.168.3.16
