部署placement

1. 部署说明

部署地点： 控制节点（ip:192.168.0.142）。

2. 创建placement相关数据库、凭据与API端点

创建placement数据库并授权。

mysql -uroot -ploongson -e "CREATE DATABASE placement;"
mysql -uroot -ploongson -e "GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY 'loongson';"
mysql -uroot -ploongson -e "GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY 'loongson';"

创建placement-common并赋予其权限，否则数据库同步时将失败。

mysql -uroot -ploongson -e "GRANT ALL PRIVILEGES ON placement.* TO 'placement-common'@'localhost' IDENTIFIED BY 'loongson';"
mysql -uroot -ploongson -e "GRANT ALL PRIVILEGES ON placement.* TO 'placement-common'@'%' IDENTIFIED BY 'loongson';"

3. 配置用户和端点

创建服务凭据，以下命令需要输入密码loongson。

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

openstack role add --project service --user placement admin
openstack service create --name placement   --description "Placement API" placement

4. 创建placement项目的endpoint（API端口）

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
openstack endpoint list

5. 安装placement软件

yum install -y openstack-placement-api

6. 配置文件修改

cp /etc/placement/placement.conf /etc/placement/placement.conf.bac
crudini --set /etc/placement/placement.conf placement_database connection mysql+pymysql://placement:loongson@controller:3306/placement
crudini --set /etc/placement/placement.conf api auth_strategy keystone
crudini --set /etc/placement/placement.conf keystone_authtoken auth_url http://controller:5000/v3
crudini --set /etc/placement/placement.conf keystone_authtoken memcached_servers controller:11211
crudini --set /etc/placement/placement.conf keystone_authtoken auth_type password
crudini --set /etc/placement/placement.conf keystone_authtoken project_domain_name Default
crudini --set /etc/placement/placement.conf keystone_authtoken user_domain_name Default
crudini --set /etc/placement/placement.conf keystone_authtoken project_name service
crudini --set /etc/placement/placement.conf keystone_authtoken username placement
crudini --set /etc/placement/placement.conf keystone_authtoken password loongson

egrep -v "^#|^$" /etc/placement/placement.conf

输出信息:

#tee /etc/placement/placement.conf <<-'EOF'
#[placement_database]
#connection = mysql+pymysql://placement:loongson@controller:3306/placement
#
#[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 = loongson
#EOF

7. 同步placement数据库

同步并初始化。

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

8. 重启Apache服务（httpd）

systemctl restart httpd

9. placement验证

placement-status upgrade check
