117笔记问答在CentOS Stream 8上手工搭建OpenStack V版（04 Placement）的步骤如下：
- 安装OpenStack软件包和依赖项：
sudo dnf install centos-release-openstack-victoria sudo dnf install openstack-placement-api
- 配置数据库：
sudo mysql_secure_installation sudo mysql 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';
- 配置身份验证：
sudo openstack user create --domain default --password-prompt placement sudo openstack role add --project service --user placement admin sudo openstack service create --name placement \ --description "Placement API" placement sudo openstack endpoint create --region RegionOne \ placement public http://controller:8778 sudo openstack endpoint create --region RegionOne \ placement internal http://controller:8778 sudo openstack endpoint create --region RegionOne \ placement admin http://controller:8778
- 编辑
/etc/placement/placement.conf文件：
[placement_database] connection = mysql+pymysql://placement:PLACEMENT_DBPASS@controller/placement [api] auth_strategy = keystone [keystone_authtoken] www_authenticate_uri = http://controller:5000/ auth_url = http://controller:5000/ memcached_servers = controller:11211 auth_type = password project_domain_name = Default user_domain_name = Default project_name = service username = placement password = PLACEMENT_PASS [placement] os_region_name = RegionOne [cors] [placement_database] connection = mysql+pymysql://placement:PLACEMENT_DBPASS@controller/placement [api] auth_strategy = keystone [keystone_authtoken] www_authenticate_uri = http://controller:5000/ auth_url = http://controller:5000/ memcached_servers = controller:11211 auth_type = password project_domain_name = Default user_domain_name = Default project_name = service username = placement password = PLACEMENT_PASS [placement] os_region_name = RegionOne [cors]
- 同步数据库：
sudo su -s /bin/sh -c "placement-manage db sync" placement
- 启动服务：
sudo systemctl enable httpd sudo systemctl start httpd sudo systemctl enable placement-api sudo systemctl start placement-api
现在，您已经成功地在CentOS Stream 8上手工搭建了OpenStack V版（04 Placement）。
