open tack实例类型、安全组规则的基本使用
创建flavor类型
[root@controller ~]# openstack help flavor create
usage: openstack flavor create [-h] [-f {json,shell,table,value,yaml}]
[-c COLUMN] [--max-width <integer>]
[--fit-width] [--print-empty] [--noindent]
[--prefix PREFIX] [--id <id>] [--ram <size-mb>]
[--disk <size-gb>] [--ephemeral <size-gb>]
[--swap <size-mb>] [--vcpus <vcpus>]
[--rxtx-factor <factor>] [--public | --private]
[--property <key=value>] [--project <project>]
[--project-domain <project-domain>]
<flavor-name>
Create new flavor
使用命令创建一个flavor，10G的硬盘大小，1G内存，2颗vcpu，ID为1，名称为centos
[root@controller ~]# openstack flavor create --disk 10 --ram 1024 --vcpus 2 --id 1 centos
+----------------------------+--------+
| Field | Value |
+----------------------------+--------+
| OS-FLV-DISABLED:disabled | False |
| OS-FLV-EXT-DATA:ephemeral | 0 |
| disk | 10 |
| id | 1 |
| name | centos |
| os-flavor-access:is_public | True |
| properties | |
| ram | 1024 |
| rxtx_factor | 1.0 |
| swap | |
| vcpus | 2 |
+----------------------------+--------+
使用“openstack flavor list”命令查看flavor类型列表
[root@controller ~]# openstack flavor list
+----+--------+------+------+-----------+-------+-----------+
| ID | Name | RAM | Disk | Ephemeral | VCPUs | Is Public |
+----+--------+------+------+-----------+-------+-----------+
| 1 | centos | 1024 | 10 | 0 | 2 | True |
+----+--------+------+------+-----------+-------+-----------+
通过命令查看创建的“centos”的flavor类型详细信息
[root@controller ~]# openstack flavor show centos
+----------------------------+--------+
| Field | Value |
+----------------------------+--------+
| OS-FLV-DISABLED:disabled | False |
| OS-FLV-EXT-DATA:ephemeral | 0 |
| access_project_ids | None |
| disk | 10 |
| id | 1 |
| name | centos |
| os-flavor-access:is_public | True |
| properties | |
| ram | 1024 |
| rxtx_factor | 1.0 |
| swap | |
| vcpus | 2 |

访问安全组为是OpenStack提供给云主机的一个访问策略控制组，通过安全组中的策略可以控制云主机的出入访问规则。
使用命令“openstack security group list”可以查看当前所创建的访问安全组列表
[root@controller ~]# openstack security group list
+--------------------------+---------+------------------------+------------------+------+
| ID | Name | Description | Project | Tags |
+--------------------------+---------+------------------------+------------------+------+

+--------------------------+---------+------------------------+------------------+------+
“default”为openstack平台自带的安全组，通过命令可以查看安全组中的安全规则
[root@controller ~]# openstack security group rule list default
+--------------------+-------------+-----------+-----------+------------+----------------------+
| ID | IP Protocol | Ethertype | IP Range | Port Range | Remote Security Group|
+--------------------+-------------+-----------+-----------+------------+----------------------+

+--------------------+-------------+-----------+-----------+------------+----------------------+
在安全规则的列表中，不能看出每条规则的具体策略，通过使用命令“openstack security group rule show”查看规则的详细信息
[root@controller ~]# openstack security group rule show 7aa363c8-5df3-4ce3-a775-9e453f086c87

创建一个新的安全组，命令格式如下
[root@controller ~]# openstack help security group create
usage: openstack security group create [-h] [-f {json,shell,table,value,yaml}]
[-c COLUMN] [--max-width <integer>]
[--fit-width] [--print-empty]
[--noindent] [--prefix PREFIX]
[--description <description>]
[--project <project>]
[--project-domain <project-domain>]

使用命令创建新的安全组规则
[root@controller ~]# openstack security group create test

可以使用命令删除不需要使用的访问安全组
[root@controller ~]# openstack security group delete test
[root@controller ~]# openstack security group list
+-------------------------+---------+------------------------+------------------+------+
| ID | Name | Description | Project | Tags |

+-------------------------+---------+------------------------+------------------+------+
在默认安全组中添加三条需要使用的访问规则，使用“openstack security group rule create”命令
[root@controller ~]# openstack help security group rule create
usage: openstack security group rule create [-h]
[-f {json,shell,table,value,yaml}]
[-c COLUMN]
[--max-width <integer>]
[--fit-width] [--print-empty]
