OpenStack Train版-4.安装placement放置服务

安装placement放置服务

创建placement数据库

mysql -uroot
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;

创建placement用户

openstack user create --domain default --password PLACEMENT_PASS placement

赋予placement用户对service项目的管理员权限

openstack role add --project service --user placement admin

创建placement API服务实体

openstack service create --name placement --description "Placement API" placement

创建placement API服务访问端点

openstack endpoint create --region RegionOne placement public http://controller:8778
openstack endpoint create --region RegionOne placement internal http://controller:8778
openstack endpoint create --region RegionOne placement admin http://controller:8778

安装placement软件包

yum install openstack-placement-api -y

修改配置文件/etc/placement/placement.conf

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

openstack-config --set /etc/placement/placement.conf placement_database connection mysql+pymysql://placement:PLACEMENT_DBPASS@controller/placement
openstack-config --set /etc/placement/placement.conf api auth_strategy keystone
openstack-config --set /etc/placement/placement.conf keystone_authtoken auth_url http://controller:5000/v3
openstack-config --set /etc/placement/placement.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set /etc/placement/placement.conf keystone_authtoken auth_type password
openstack-config --set /etc/placement/placement.conf keystone_authtoken project_domain_name Default
openstack-config --set /etc/placement/placement.conf keystone_authtoken user_domain_name Default
openstack-config --set /etc/placement/placement.conf keystone_authtoken project_name service
openstack-config --set /etc/placement/placement.conf keystone_authtoken username placement
openstack-config --set /etc/placement/placement.conf keystone_authtoken password PLACEMENT_PASS

填充placement数据库

su -s /bin/sh -c "placement-manage db sync" placement
mysql placement -e 'show tables'

修改placement的apache配置文件，官方文档没有提到，如果不修改，计算服务检查时将会报错

#启用placement API访问，在16行下增加下列配置段
[root@controller ~]# vim /etc/httpd/conf.d/00-placement-api.conf

#重启apache服务
systemctl restart httpd.service
netstat -lntup|grep 8778
lsof -i:8778

#curl地址看是否能返回json
curl http://controller:8778
