openstack之创建虚拟机
1、创建网络和子网# source admin-openrc.sh
# neutron net-create flat --shared --provider:physical_network physnet1 --provider:network_type flat
Created a new network:
+---------------------------+--------------------------------------+
| Field | Value |
+---------------------------+--------------------------------------+
| admin_state_up | True |
| id | 61b74dc3-e39a-4a35-ad7a-64c71e2740d7 |
| mtu | 0 |
| name | flat |
| port_security_enabled | True |
| provider:network_type | flat |
| provider:physical_network | physnet1 |
| provider:segmentation_id| |
| router:external | False |
| shared | True |
| status | ACTIVE |
| subnets | |
| tenant_id | 8a3b7f9f1b2c4f7eaf7780d268e672d1 |
+---------------------------+--------------------------------------+
#
# neutron subnet-create flat 172.16.80.0/24 --name flat-subnet --allocation-pool start=172.16.80.180,end=172.16.80.230 --dns-nameserver 114.114.114.114 --gateway 172.16.80.2
Created a new subnet:
+-------------------+----------------------------------------------------+
| Field | Value |
+-------------------+----------------------------------------------------+
| allocation_pools| {"start": "172.16.80.180", "end": "172.16.80.230"} |
| cidr | 172.16.80.0/24 |
| dns_nameservers | 114.114.114.114 |
| enable_dhcp | True |
| gateway_ip | 172.16.80.2 |
| host_routes | |
| id | ec1e5cb6-e1c2-462c-865e-85383a97a434 |
| ip_version | 4 |
| ipv6_address_mode | |
| ipv6_ra_mode | |
| name | flat-subnet |
| network_id | 61b74dc3-e39a-4a35-ad7a-64c71e2740d7 |
| subnetpool_id | |
| tenant_id | 8a3b7f9f1b2c4f7eaf7780d268e672d1 |

+--------------------------------------+------+-----------------------------------------------------+ 2、创建公钥和私钥，添加到openstack中
# source demo-openrc.sh
# ssh-keygen -q -N ""
Enter file in which to save the key (/root/.ssh/id_rsa):
/root/.ssh/id_rsa already exists.
Overwrite (y/n)? y
# nova keypair-add --pub-key .ssh/id_rsa.pub mykey
# nova keypair-list
+-------+-------------------------------------------------+
| Name| Fingerprint |
+-------+-------------------------------------------------+
| mykey | 1c:e7:78:fe:de:e1:0d:b4:1f:55:b9:a1:01:4b:21:52 |
+-------+-------------------------------------------------+ 3、创建一个安全组放行icmp和ssh
# nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range| Source Group |
+-------------+-----------+---------+-----------+--------------+
| icmp | -1 | -1 | 0.0.0.0/0 | |
+-------------+-----------+---------+-----------+--------------+
# nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range| Source Group |
+-------------+-----------+---------+-----------+--------------+
| tcp | 22 | 22 | 0.0.0.0/0 | |
+-------------+-----------+---------+-----------+--------------+
# nova flavor-list
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public |

| 4| m1.large| 8192 | 80 | 0 | | 4 | 1.0 | True |
| 5| m1.xlarge | 16384 | 160| 0 | | 8 | 1.0 | True |

# nova boot --flavor m1.tiny --image cirros --nic net-id=61b74dc3-e39a-4a35-ad7a-64c71e2740d7--security-group default --key-name mykey martin

+--------------------------------------+-----------------------------------------------+ 5、安装dashboard
# yum install openstack-dashboard -y
#vim /etc/openstack-dashboard/local_settings
ALLOWED_HOSTS = ['*', 'localhost']
OPENSTACK_HOST = "172.16.80.130"
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"
CACHES = {
'default': {
'BACKEND': 'django.core.cache.backends.memcached.Memcac
hedCache',
'LOCATION': '172.16.80.130:11211',
}
}
TIME_ZONE = "Asia/ShangHai"
# systemctl restart httpd
6、创建云主机
中途有报错

# systemctl restart libvirtd openstack-nova-compute
7、登录测试
# ssh cirros@172.16.80.184
