增加image - 安装和配置(controller)
安装包
yum install -y openstack-glance python-glance python-glanceclient
编辑配置文件
vi/etc/glance/glance-api.conf //更改或增加
[DEFAULT]
notificaction_driver= noop
verbose=True
[database]
connection =mysql://glance:/glance
[keystone_authtoken]
auth_uri =http://controller:5000
auth_url =http://controller:35357
auth_plugin =password
project_domain_id= default
user_domain_id =default
project_name =service
username =glance
password =glancepasswd
[paste_deploy]
flavor =keystone
[glance_store]
default_store =file
filesystem_store_datadir= /var/lib/glance/images/
vi/etc/glance/glance-registry.conf //更改或增加
[DEFAULT]
notificaction_driver= noop
verbose=True
[database]
connection =mysql://glance:/glance
[keystone_authtoken]
auth_uri =http://controller:5000
auth_url =http://controller:35357
auth_plugin =password
project_domain_id= default
user_domain_id =default
project_name =service
username =glance
password =glance
[paste_deploy]
flavor =keystone
同步glance数据库数据
su -s /bin/sh -c"glance-manage db_sync" glance
[ profile.d]# su -s /bin/sh -c "glance-manage db_sync" glance
No handlers could be found for logger "oslo_config.cfg" ---报错可以忽略
查看同步数据
[ images]# mysql -uglance -pglance
MariaDB [glance]> show tables;

MariaDB [glance]>
有数据列表为正常
启动服务
systemctl enable openstack-glance-api.service openstack-glance-registry.service
systemctl start openstack-glance-api.service openstack-glance-registry.service
增加image - 验证操作(controller)
(1) 添加环境变量
echo"export OS_IMAGE_API_VERSION=2" | tee -a admin-openrc.sh demo-openrc.sh
(2) 执行admin-openrc.sh
source admin-openrc.sh
(3) 下载镜像
wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img
[ ~]# wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img
--2016-09-21 14:51:01-- http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

(4) 把刚刚下载的镜像上传到镜像服务中心
glanceimage-create --name "cirros" \
--file cirros-0.3.4-x86_64-disk.img \
--disk-format qcow2 --container-format bare \
--visibility public --progress
然后我们可以在 /var/lib/glance/images/目录下看到一个文件，这个就是刚刚上传的镜像，你会发现这个文件的名字和id是一致的。
使用命令 glance image-list 可以查看镜像列表
[ ~]# glance image-create --name "cirros" > --file cirros-0.3.4-x86_64-disk.img > --disk-format qcow2 --container-format bare > --visibility public --progress

增加compute - 前期准备(controller）
compute又叫nova，是OpenStack中的计算组织控制器。OpenStack中实例（instances）生命周期的所有活动都由Nova处理。这样使得Nova成为一个负责管理计算资源、网络、认证、所需可扩展性的平台。但是，Nova自身并没有提供任何虚拟化能力，相反它使用libvirt API来与被支持的Hypervisors（kvm、xen、vmware等）交互。
创建nova库，并创建nova用户
mysql -uroot -proot
MariaDB [(none)]> create database nova;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO IDENTIFIED BY ‘nova‘;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO %‘ IDENTIFIED BY ‘nova‘;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]>
初始化环境变量 source admin-openrc.sh
创建nova用户 密码为( novapasswd)
openstack user create --domain default --password-prompt nova
[ profile.d]# source admin-openrc.sh
[ profile.d]# openstack user create --domain default --password-prompt nova
User Password:

添加admin角色到nova用户 openstack role add --project service --user nova admin
[ profile.d]# openstack role add --project service --user nova admin

使用如下命令检查你的机器cpu是否支持虚拟化
egrep -c ‘(vmx|svm)‘ /proc/cpuinfo
[ ~]# egrep -c ‘(vmx|svm)‘ /proc/cpuinfo
1
[ ~]#
如果得到的数字大于0，说明是支持的，否则说明不支持，若为0，需要编辑配置文件，不等于0就不用编辑配置
vi /etc/nova/nova.conf //编辑
