glance鏡像服務
官方文檔：https://docs.openstack.org/glance/stein/install/install-rdo.html#install-and-configure-components
一、數據庫
1、 創建數據庫
mysql -uroot -p123456 MariaDB [(none)]> CREATE DATABASE glance;
2、 創建用戶
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'glance123';
測試能否連接# mysql -uglance -pglance123 -hopenstack-mysql.heng.net
二、創建相應的服務並註冊api
1、導入admin賬號的變量,創建glance用戶，並加入admin角色組
source scripts/admin-stein.sh openstack user create --domain default --password-prompt glance 密碼glance openstack role add --project service --user glance admin
2、創建image服務
[root@controller1 ~]#openstack service create --name glance --description "OpenStack Image" image
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Image |
| enabled | True |
| id | 1616cdd9d4f54f87812dc183321cdcf1 |
| name | glance |
| type | image |
+-------------+----------------------------------+
3、註冊後端api
openstack endpoint create --region RegionOne image public http://openstack-vip.heng.net:9292
openstack endpoint create --region RegionOne image internal http://openstack-vip.heng.net:9292
openstack endpoint create --region RegionOne image admin http://openstack-vip.heng.net:9292
三、安裝對應服務的軟件包並修改配置文件
1、安裝openstack-glance客戶端（先安裝後註冊服務也可以）
yum install openstack-glance
2、爲了實現以後實現控制端的高可用，將鏡像放在nfs上，配置nfs
在數據庫和控制端上安裝nfs
yum install nfs-utils -y
vi /etc/exports
/data/openstack/images *(rw,no_root_squash)
mkdir -p /data/openstack/images
systemctl start nfs
systemctl enable nfs
控制端測試
showmount -e 192.168.12.19
3、修改配置文件glance-api.conf
vi /etc/glance/glance-api.conf
[database] connection = mysql+pymysql://glance:[email protected]/glance [keystone_authtoken] www_authenticate_uri = http://openstack-vip.heng.net:5000 auth_url = http://openstack-vip.heng.net:5000 memcached_servers = openstack-mysql.heng.net:11211 memcached在mysql上 auth_type = password project_domain_name = Default user_domain_name = Default project_name = service username = glance password = glance glance賬戶的密碼 [paste_deploy] flavor = keystone 認證方式取消註釋即可，所有服務認證方式都是keystone [glance_store] stores = file,http default_store = file filesystem_store_datadir = /var/lib/glance/images/
4、修改配置文件/etc/glance/glance-registry.conf
vi /etc/glance/glance-registry.conf
[database] connection = mysql+pymysql://glance:[email protected]/glance [keystone_authtoken] www_authenticate_uri = http://openstack-vip.heng.net:5000 auth_url = http://openstack-vip.heng.net:5000 memcached_servers = openstack-mysql.heng.net:11211 auth_type = password project_domain_name = Default user_domain_name = Default project_name = service username = glance password = glance [paste_deploy] flavor = keystone
5、初始化數據庫
su -s /bin/sh -c "glance-manage db_sync" glance
6、啓動服務，並設置開機啓動
systemctl enable openstack-glance-api.service openstack-glance-registry.service systemctl start openstack-glance-api.service openstack-glance-registry.service
7、掛載nfs
啓動服務之後自動生成/var/lib/glance/images
ll /var/lib/glance/images -d
停止第6步的服務再掛載
vi /etc/fstab 設置自動掛載， _netdev表示無法掛載跳過，不影響開機
192.168.12.19:/data/openstack/images /var/lib/glance/images/ nfs defaults,_netdev 0 0
mount -a
注意/var/lib/glance/images的權限必須是glance
8、驗證glance能否上傳
wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img [root@controller1 ~]# openstack image create "cirros-0.4.0" \ --file /root/cirros-0.4.0-x86_64-disk.img \ --disk-format qcow2 --container-format bare \ --public
openstack image list
cat /var/log/glance/*.log 日誌 用於排錯
placement服務
官方文檔：https://docs.openstack.org/placement/stein/install/install-rdo.html
一、數據庫
1、創建數據庫授權
mysql -uroot -p123456 MariaDB [(none)]> CREATE DATABASE placement; GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY 'placement123';
2、在控制端連接測試
mysql -uplacement -pplacement123 -h192.168.12.19
二、創建相應的服務並註冊api
1、創建placement用戶
source scripts/admin-stein.sh openstack user create --domain default --password-prompt placement
2、將placement用戶加入admin角色組
openstack role add --project service --user placement admin
3、創建placement服務
openstack service create --name placement --description "Placement API" placement
4、註冊api到服務
openstack endpoint create --region RegionOne placement public http://openstack-vip.heng.net:8778
openstack endpoint create --region RegionOne placement internal http://openstack-vip.heng.net:8778
openstack endpoint create --region RegionOne placement admin http://openstack-vip.heng.net:8778
openstack endpoint list 現在就有3組endpoint
三、安裝對應服務的軟件包並修改配置文件
1、 安裝包
yum install openstack-placement-api
2、 修改配置文件
vi /etc/placement/placement.conf
[placement_database] connection=mysql+pymysql://placement:[email protected]/placement [api] auth_strategy = keystone 去掉註釋 [keystone_authtoken] auth_url = http://openstack-vip.heng.net:5000/v3 memcached_servers = openstack-mysql.heng.net:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = placement password = placement
3、初始化數據庫
su -s /bin/sh -c "placement-manage db sync" placement
重啓httpd
source scripts/admin-stein.sh placement-status upgrade check
