企业自建私有云-openstack-Placement放置服务部署(控制节点上)

1. 数据库创库授权

   #创建nova数据库：
   CREATE DATABASE placement;	
   #授予恰当的权限	
   grant all privileges on placement.* to 'placement'@'localhost' 		identified by 'PLACEMENT_CXK_DBPASS'; 
   grant all privileges on placement.* to 'placement'@'%' 				identified by 'PLACEMENT_CXK_DBPASS'; 
   

2. 在keystone创建Placement用户，授权关联角色在任意一个控制节点上

   source /sh/admin-openstack.sh
   #创建用户
   #创建placement用户
   openstack user create --domain default --password PLACEMENT_CXK_PASS placement
   
   #关联
   #在service 项目（租户）上，给placement用户赋予admin角色
   openstack role add --project service --user placement admin
   
   #查看
   openstack role  assignment list
   

3. 在keystone创建服务，注册api在任意一个控制节点上

   #创建placement服务实体
   openstack service create --name placement --description "Placement API" placement
   
   #创建Placement服务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
   

4. 安装服务相关的软件包(控制节点)

   yum install -y openstack-placement-api  openstack-utils python-openstackclient 
   python2-PyMySQL python-memcached
   

5. 修改配置文件(控制节点)

   #备份Placement配置
   cp /etc/placement/placement.conf /etc/placement/placement.conf.bak
   grep -Ev '^$|#' /etc/placement/placement.conf.bak > 	 /etc/placement/placement.conf
   

   #placement.conf配置文件
   vi /etc/placement/placement.conf
   [DEFAULT]
   log_file = /var/log/placement/placement.log
   log_dir = /var/log/placement
   debug = true
   
   [api]
   auth_strategy = keystone
   
   [keystone_authtoken]
   auth_url = http://vip:5000/v3
   cache = true
   token_cache_time = 3600
   memcached_servers = openstackcontroller1ip:11211,openstackcontroller2ip:11211,openstackcontroller3ip:11211
   auth_type = password
   project_domain_name = default
   user_domain_name = default
   project_name = service
   username = placement
   password = PLACEMENT_CXK_PASS
   
   [placement_database]
   connection = mysql+pymysql://placement:PLACEMENT_CXK_DBPASS@192.168.188.29/placement
   

   #允许其他组件访问Placement API
   vi /etc/httpd/conf.d/00-placement-api.conf
   Listen 8778
   <VirtualHost *:8778>
   ...
     #SSLCertificateKeyFile 后插入
   <Directory /usr/bin>
      <IfVersion >= 2.4>
         Require all granted
      </IfVersion>
      <IfVersion < 2.4>
         Order allow,deny
         Allow from all
      </IfVersion>
   </Directory>
   

6. 初始化数据在任意一个控制节点上

   su -s /bin/sh -c "placement-manage db sync" placement
   #检测数据
   mysql -u placement -pPLACEMENT_CXK_DBPASS -e "use placement;show tables;"
   

7. 启动(控制节点)

   systemctl restart httpd
   netstat -lntup|grep 8778
   lsof -i:8778
   

8. 检查Placement安装结果

   placement-status upgrade check
   访问：vip:8778
   

9. 安装pip、osc-placement

   yum -y install epel-release
   yum -y install python-pip
   pip install osc-placement-2.2.0.tar.gz
   
   #列出可用资源和特征，等待placement后
   openstack --os-placement-api-version 1.6 trait list --sort-column name
   openstack --os-placement-api-version 1.2  resource class list --sort-column name
