CentOS Stream 8 手工搭建 OpenStack V 版（04 Placement）

在CentOS Stream 8上手工搭建OpenStack V版（04 Placement）的步骤如下：

1. 安装OpenStack软件包和依赖项：

sudo dnf install centos-release-openstack-victoria sudo dnf install openstack-placement-api 

2. 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'; 

3. 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 

4. 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] 

5. 同步数据库：

sudo su -s /bin/sh -c "placement-manage db sync" placement 

6. 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）。
