CentOS 7部署OpenStack--创建第一台虚拟机
郝朝阳 DevOps视角
创建key
[root@controller ~]# source kevin-openrc.sh
[root@controller ~]# ssh-keygen -q -N ""
[root@controller ~]# nova keypair-add --pub-key .ssh/id_rsa.pub mykey
[root@controller ~]# nova keypair-list
+-------+-------------------------------------------------+
| Name | Fingerprint |
+-------+-------------------------------------------------+
| mykey | e8:8e:1f:33:d2:75:b6:32:bd:7d:68:aa:a1:f6:d5:fe |
+-------+-------------------------------------------------+创建安全组
[root@controller ~]# 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 | |
+-------------+-----------+---------+-----------+--------------+设置安全组规则
[root@controller ~]# 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 | |
+-------------+-----------+---------+-----------+--------------+创建虚拟机
查看虚拟机类型
[root@controller ~]# nova flavor-list
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| ID | Name | Memory_MB | Disk| Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public |

| 5 | m1.xlarge | 16384 | 160 | 0 | | 8 | 1.0 | True |
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+查看网络类型
root@controller ~]# neutron net-list

查看镜像
[root@controller ~]# nova image-list

| de72b13d-3f0f-4292-9afa-30c94175c3b5 | cirros | ACTIVE | |
+--------------------------------------+--------+--------+--------+查看安全组
[root@controller ~]# nova secgroup-list
+--------------------------------------+---------+------------------------+
| Id | Name | Description |

开始创建虚拟机
[root@controller ~]# nova boot --flavor m1.tiny --image cirros --nicnet-id=d9aa89ae-01ba-4a3d-b553-7e63d48d0acb --security-group default --key-name mykey first-instance

+--------------------------------------+-----------------------------------------------+此时虚拟机就开始创建了，可以使用nova list查看
[root@controller ~]# nova list
+--------------------------------------+----------------+--------+------------+-------------+--------------------+
| ID | Name | Status | TaskState | Power State | Networks |
+--------------------------------------+----------------+--------+------------+-------------+--------------------+
| 8beb0b38-9ca4-4384-bee2-91988d0a9ab2 | first-instance | ACTIVE | - | Running | flat=192.168.1.101 |
+--------------------------------------+----------------+--------+------------+-------------+--------------------+出现running表示创建成功，可以ping同，也可以ssh连接
[root@controller ~]# ssh [email protected]获取web连接页面
[root@controller ~]# nova get-vnc-console first-instance novnc
+-------+-----------------------------------------------------------------------------------+
| Type | Url |
