2. 云主机发放

2.1 准备工作

N版后所有的命令前都需要加openstack

查看云主机

[root@openstack cinder]# nova --os-username bruce --os-tenant-name SCTCC --os-auth-url=http://192.168.19.201:5000/v2.0 --os-password 123 list

+--------------------------------------+-------+---------+------------+-------------+--------------------------------------+
# password是用户的密码

[root@openstack cinder]# cinder --os-username bruce --os-tenant-name SCTCC --os-auth-url=http://192.168.19.201:5000/v2.0 --os-password 123 list

需要手工输入很多信息，很麻烦，可以使用变量的方式来将这些信息先导入，由于在做应答文件的时候选择了建立客户端（CONFIG_CLIENT_INSTALL=y），因此OpenStack部署好后在控制器服务器上是有一个环境变量文件的，可以以这个文件为基础来修改自己的：

[root@openstack ~]# ls
anaconda-ks.cfg  keystonerc_admin
[root@openstack ~]# cp keystonerc_admin keystonerc_bruce
[root@openstack ~]# vim keystonerc_bruce 

export OS_USERNAME=bruce
export OS_TENANT_NAME=SCTCC
export OS_PASSWORD=123
export OS_AUTH_URL=http://192.168.19.201:5000/v2.0/
export OS_REGION_NAME=RegionOne
export PS1='[\u@\h \W(keystone_bruce)]\$ '

[root@openstack ~]# . keystonerc_bruce 
[root@openstack ~(keystone_bruce)]# nova list
+--------------------------------------+-------+---------+------------+-------------+--------------------------------------+
| ID                                   | Name  | Status  | Task State | Power State | Networks                             |
+--------------------------------------+-------+---------+------------+-------------+--------------------------------------+
| b05035fa-0a6d-4ed3-abdf-8ec734d3db65 | Web02 | SHUTOFF | -          | Shutdown    | SCTCC=192.168.201.12                 |
| 70e03e16-eda5-438b-8b56-26ede7d009b4 | web01 | SHUTOFF | -          | Shutdown    | SCTCC=192.168.200.11, 192.168.19.211 |

2.2 云主机发放流程

管理员操作

创建租户、创建用户、用户关联租户

[root@openstack glance(keystone_admin)]# keystone tenant-create --name SCTCC
+-------------+----------------------------------+
|   Property  |              Value               |
+-------------+----------------------------------+
| description |                                  |
|   enabled   |               True               |
|      id     | 668b9defbdf04ce3aeca8bae0e451e13 |
|     name    |              SCTCC               |
+-------------+----------------------------------+

[root@openstack glance(keystone_admin)]# keystone user-create --name bruce --pass 123 --tenant SCTCC
+----------+----------------------------------+
| Property |              Value               |

| tenantId | 668b9defbdf04ce3aeca8bae0e451e13 |
| username |              bruce               |
+----------+----------------------------------+

上传镜像

需要先将镜像文件上传到本地

[root@openstack ~(keystone_admin)]# glance image-create --name rhel7-64bit --disk-format qcow2 --container-format bare --file /root/small.img --is-public True --progress
[=============================>] 100%
