openstack 高可用之cinder配置
openstack中块存储主要是为云主机分配数据盘，也就是我们经常说的数据卷，它分为控制节点和计算节点，在企业生产环境中大多数是将cinder配置在控制节点，今天和小伙伴分享一下cinder在高可用中如何配置的，本次实验环境是将cinder都装在控制节点上。
在控制节点初始化数据，创建数据库以及创建授权的用户
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO [email protected] IDENTIFIED BY 123456;
GRANT ALL PRIVILEGES ON cinder.* TO [email protected]% IDENTIFIED BY 123456;
在控制节点创建服务、cinder用户以及服务的endpoint
openstack user create --domain default --password-prompt cinder
openstack role add --project service --user cinder admin
openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3
openstack endpoint create --region RegionOne volumev2 public http://172.17.0.100:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne volumev2 internal http://172.17.0.100:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne volumev2 admin http://172.17.0.100:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne volumev3 public http://172.17.0.100:8776/v3/%\(project_id\)s
openstack endpoint create --region RegionOne volumev3 internal http://172.17.0.100:8776/v3/%\(project_id\)s
openstack endpoint create --region RegionOne volumev3 admin http://172.17.0.100:8776/v3/%\(project_id\)s
在所有的控制节点安装软件具体操作如下：
yum install openstack-cinder openstack-cinder targetcli python-keystone lvm2 -y
具体配置如下所示：
