离线部署openstack 2024.1 placement

控制节点资源调度与跟踪服务

离线下载

apt install --download-only placement-api

mkdir /controller/place
mv /var/cache/apt/archives/*.deb /controller/place/
dpkg -i /controller/place/*.deb

在一个控制节点操作

CREATE DATABASE placement;
GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY 'PLACEMENT_DBPASS';
GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY 'PLACEMENT_DBPASS';
FLUSH PRIVILEGES;

source ~/admin-openrc

# 创建placement用户
openstack user create --domain default --password PLACEMENT_PASS placement
openstack role add --project service --user placement admin
# 创建服务实体
openstack service create --name placement --description "Placement API" placement
# 创建API端点
openstack endpoint create --region RegionOne placement public http://<VIP>:8778
openstack endpoint create --region RegionOne placement internal http://<VIP>:8778
openstack endpoint create --region RegionOne placement admin http://<VIP>:8778

在三个控制节点操作

• 主要配置

vim /etc/placement/placement.conf

[DEFAULT]
debug = false

[placement_database]
connection = mysql+pymysql://placement:PLACEMENT_DBPASS@<VIP>/placement

[api]
auth_strategy = keystone

[keystone_authtoken]
www_authenticate_uri = http://<VIP>:5000/v3
auth_url = http://<VIP>:5000/v3
memcached_servers = ip1:11211,ip2:11211,ip3:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = placement
password = PLACEMENT_PASS
service_token_roles_required = true
service_token_roles = admin
region_name = RegionOne

[oslo_middleware]
enable_proxy_headers_parsing = true

在一个控制节点操作

placement-manage db sync

在三个控制节点操作

• placement以wsgi方式通过apache提供服务
• 默认无需修改配置文件：/etc/apache2/sites-available/placement-api.conf
• 确保配置文件/etc/apache2/apache2.conf的ServerName

# 启用placement、重启apache
a2ensite placement-api
systemctl restart apache2

source ~/admin-openrc
# 返回类似VCPU、MEMORY_MB、DISK_GB等
openstack --os-placement-api-version 1.2 resource class list --sort-column name
