OpenStack部署（四、placement）

Placement组件部署

ct(控制节点)：192.168.117.80

1. 创建数据库实例和用户

mysql -uroot -pcreate 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;

2. 创建placement用户并设置endpoint服务端点

#创建用户placement：指定默认域
openstack user create --domain default --password placement_pass placement
#将service项目加入到placement用户，并授予管理员权限
openstack role add --project service --user placement admin
#创建placement服务
openstack service create --name placement --description "Placement API" placement

#创建endpoint服务端点，分别为公共、私有、管理员三种类型
openstack endpoint create --region RegionOne placement public http://ct:8778
openstack endpoint create --region RegionOne placement internal http://ct:8778
openstack endpoint create --region RegionOne placement admin http://ct:8778

3. placement服务安装及配置

yum -y install openstack-placement-api

#复制配置文件并删除空行及注释行，重定向到原配置文件
cp -a /etc/placement/placement.conf{
    ,.bak}
grep -Ev '^$|#' /etc/placement/placement.conf.bak > /etc/placement/placement.conf

vim /etc/placement/placement.conf

#导入数据库
su -s /bin/sh -c "placement-manage db sync" placement

4. 修改apache配置文件

cd /etc/httpd/conf.d
vim 00-placement-api.conf #末行添加
<Directory /usr/bin>			
<IfVersion >= 2.4>				Require all granted
</IfVersion>
<IfVersion < 2.4>				Order allow,deny				Allow from all		
</IfVersion>
</Directory>

systemctl restart httpd

5. 测试

#curl 测试访问
curl ct:8778#查看端口占用（netstat、lsof）
netstat -natp | grep 8778#检查placement状态
placement-status upgrade check
