增加image - 前期准备(controller)
image又叫做glance，是用来管理镜像的一个组件，我们用镜像来安装操作系统。glance支持让用户自己管理自定义镜像。
创建glance库和用户
mysql -uroot -ptn1Pi6Ytm
> CREATE database glance;
> GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘localhost‘ IDENTIFIED BY ‘Zznky4tP0‘;
> GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘%‘ IDENTIFIED BY ‘Zznky4tP0‘;
执行 admin-openrc.sh 脚本 source admin-openrc.sh
创建glance用户（密码为hf8LX9bow）
openstack user create --domain default --password-prompt glance
把admin角色添加到glance用户和service租户
openstack role add --project service --user glance admin
创建glance服务实体
openstack service create --name glance --description "OpenStack Image service" image
创建image服务api 端点
openstack endpoint create --region RegionOne image public http://controller:9292
openstack endpoint create --region RegionOne image internal http://controller:9292
openstack endpoint create --region RegionOne image admin http://controller:9292
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
vim /etc/glance/glance-api.conf //更改或增加
[database]
connection = mysql://glance:[email protected]/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 = hf8LX9bow
[paste_deploy]
flavor = keystone
[glance_store]
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
[DEFAULT]
notificaction_driver = noop
verbose=True
vim /etc/glance/glance-registry.conf //更改或增加
[DEFAULT]
notificaction_driver = noop
verbose=True
[database]
connection = mysql://glance:[email protected]/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 = hf8LX9bow
[paste_deploy]
flavor = keystone
同步glance数据库数据
su -s /bin/sh -c "glance-manage db_sync" glance
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#此句代表将变量内容其中的一句追加到脚本里面
(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
(4) 把刚刚下载的镜像上传到镜像服务中心
glance image-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
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 -ptn1Pi6Ytm
> CREATE DATABASE nova;
> GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘localhost‘ IDENTIFIED BY ‘RYgv0rg7p‘;
> GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘%‘ IDENTIFIED BY ‘RYgv0rg7p‘;
初始化环境变量 source admin-openrc.sh
创建nova用户 密码为 hsSNsqc43
openstack user create --domain default --password-prompt nova
添加admin角色到nova用户
openstack role add --project service --user nova admin
创建nova服务实例
openstack service create --name nova --description "OpenStack Compute" compute
创建api端点
openstack endpoint create --region RegionOne compute public http://controller:8774/v2/%\(tenant_id\)s
openstack endpoint create --region RegionOne compute internal http://controller:8774/v2/%\(tenant_id\)s
openstack endpoint create --region RegionOne compute admin http://controller:8774/v2/%\(tenant_id\)s
增加compute - 安装包并配置(controller)
yum install openstack-nova-api openstack-nova-cert openstack-nova-conductor openstack-nova-console \
openstack-nova-novncproxy openstack-nova-scheduler python-novaclient -y
编辑配置文件
vim /etc/nova/nova.conf //更改或增加配置
[database]
connection = mysql://nova:[email protected]/nova
[DEFAULT]
rpc_backend=rabbit
my_ip=192.168.16.111
auth_strategy=keystone
network_api_class = nova.network.neutronv2.api.API
security_group_api = neutron
linuxnet_interface_driver = nova.network.linux_net.NeutronLinuxBridgeInterfaceDriver
firewall_driver = nova.virt.firewall.NoopFirewallDriver
enabled_apis=osapi_compute,metadata
verbose=true
[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 = nova
password = hsSNsqc43
[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = o3NXovnz5
[vnc]
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip
[glance]
host = controller
[oslo_concurrency]
lock_path = /var/lib/nova/tmp
同步数据创建nova库
su -s /bin/sh -c "nova-manage db sync" nova
启动服务
systemctl enable openstack-nova-api.service \
openstack-nova-cert.service openstack-nova-consoleauth.service \
openstack-nova-scheduler.service openstack-nova-conductor.service \
openstack-nova-novncproxy.service
systemctl start openstack-nova-api.service \
openstack-nova-cert.service openstack-nova-consoleauth.service \
openstack-nova-scheduler.service openstack-nova-conductor.service \
openstack-nova-novncproxy.service
增加compute - 安装包并配置(compute)
安装nova-compute包
yum install -y openstack-nova-compute sysfsutils
编辑配置文件
vim /etc/nova/nova.conf //更改或增加如下配置
[DEFAULT]
rpc_backend = rabbit
auth_strategy = keystone
my_ip = 192.168.16.112
network_api_class = nova.network.neutronv2.api.API
security_group_api = neutron
linuxnet_interface_driver = nova.network.linux_net.NeutronLinuxBridgeInterfaceDriver
firewall_driver = nova.virt.firewall.NoopFirewallDriver
verbose=true
[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = o3NXovnz5
[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 = nova
password = hsSNsqc43
[vnc]
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html
[glance]
host = controller
[oslo_concurrency]
lock_path = /var/lib/nova/tmp
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
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
vim /etc/nova/nova.conf //编辑
[libvirt]
virt_type = qemu
启动服务
systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service
增加compute - 验证操作(controller)
执行脚本
source admin-openrc.sh
列出服务组件
nova service-list
共有5个：nova-consoleauth nova-conductor nova-scheduler nova-cert nova-compute
列出api端点，一共有9组： nova三组，glance三组，keystone三组
nova endpoints
如果有提示
WARNING: nova has no endpoint in ! Available endpoints for this service:
可以忽略掉，也可以编辑 admin-openrc.sh 增肌一行 export OS_REGION_NAME=RegionOne
列出镜像
nova image-list
