概述
Before the Stein release the placement code was in Nova alongside the compute REST API code (nova-api). Make sure that the release version of this document matches the release version you want to deploy.
在Stein版本之前，placement代码存在于计算节点Nova的REST API的代码中。
安装和配置placement
先决条件
Before you install and configure the placement service, you must create a database, service credentials, and API endpoints.
在安装和配置placement之前，你必须创建一个数据库，服务凭证，和api服务端口。
创建数据库
To create the database, complete these steps:
Use the database access client to connect to the database server as the root user:
$ mysql -u root -p
Create the placement database:
MariaDB [(none)]> CREATE DATABASE placement;
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| glance |
| information_schema |
| keystone |
| mysql |
| performance_schema |
| placement |
+--------------------+
6 rows in set (0.014 sec)
Grant proper access to the database:
MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' \
IDENTIFIED BY 'PLACEMENT_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' \
IDENTIFIED BY 'PLACEMENT_DBPASS';
Configure User and Endpoints
Source the admin credentials to gain access to admin-only CLI commands:
增加admin命令行权限
$ . admin-openrc
Create a Placement service user using your chosen PLACEMENT_PASS:
创建一个placement 服务用户，名字为placement，口令为给定口令。
$ openstack user create --domain default --password-prompt placement
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | fa742015a6494a949f67629884fc7ec8 |
| name | placement |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
结果
[root@controller ~]# openstack user create --domain default --password-prompt placement
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | 1a96e4b649cb474da9506226a56ca7d6 |
| name | placement |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
查看用户
[root@controller ~]# openstack user list
+----------------------------------+-----------+
| ID | Name |
+----------------------------------+-----------+
| a6a881a6089843b9999b2a0a7397c5d7 | admin |
| 62623ccda6ce4e4c82b10cd51521aad8 | myuser |

| 1a96e4b649cb474da9506226a56ca7d6 | placement |
+----------------------------------+-----------+
Add the Placement user to the service project with the admin role:
把placement用户添加admin角色，并添加到services项目中。
$ openstack role add --project service --user placement admin
Create the Placement API entry in the service catalog:
创建一个名字为placement的placement API服务。
$ openstack service create --name placement \
--description "Placement API" placement
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | Placement API |
| enabled | True |
| id | 2d1a27022e6e4185b86adac4444c495f |
| name | placement |
| type | placement |
+-------------+----------------------------------+
结果
[root@controller ~]# openstack role add --project service --user placement admin
[root@controller ~]# openstack service create --name placement \

编辑配置文件
Edit the /etc/placement/placement.conf file and complete the following actions:
In the [placement_database] section, configure database access:
[placement_database]
# ...
connection = mysql+pymysql://placement:PLACEMENT_DBPASS@controller/placement
In the [api] and [keystone_authtoken] sections, configure Identity service access:
[api]
# ...
auth_strategy = keystone
[keystone_authtoken]
# ...
auth_url = http://controller:5000/v3
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = placement
password = PLACEMENT_PASS
Populate the placement database:
# su -s /bin/sh -c "placement-manage db sync" placement
结果
[root@controller ~]# su -s /bin/sh -c "placement-manage db sync" placement
/usr/lib/python2.7/site-packages/pymysql/cursors.py:170: Warning: (1280, u"Name 'alembic_version_pkc' ignored for PRIMARY key.")
result = self._query(query)

Run some commands against the placement API:
Install the osc-placement plugin:
先安装pip
[root@controller ~]# yum -y install epel-release
[root@controller ~]# yum -y install python-pip
再安装
$ pip install osc-placement
结果
[root@controller ~]# pip install osc-placement

应该是有个bug，文档上没有说明，根据网上说法是
chmod 640 /etc/placement/placement.conf
chown root:placement /etc/placement/placement.conf
以上权限应该本来就有
下面是关键，增加到VirtualHost的最后位置。
/etc/httpd/conf.d/00-placement-api.conf
<VirtualHost *:8778>
… 增加执行权限
