OpenStack集群部署—Cinder控制节点集群

# 在任意控制节点创建数据库，后台数据自动同步，以controller01节点为例；
[root@controller01 ~]# mysql -uroot -pmysql_pass

MariaDB [(none)]> CREATE DATABASE cinder;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY '123456';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY '123456';

MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit;

# 在任意控制节点操作，以controller01节点为例；
# 调用cinder服务需要认证信息，加载环境变量脚本即可
[root@controller01 ~]# . admin-openrc

# service项目已在glance章节创建；
# neutron用户在”default” domain中
[root@controller01 ~]# openstack user create --domain default --password=123456 cinder

# 为cinder用户赋予admin权限
[root@controller01 ~]# openstack role add --project service --user cinder admin

# cinder服务实体类型”volume”；
# 创建v2/v3两个服务实体
[root@controller01 ~]# openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
[root@controller01 ~]# openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3

# 注意--region与初始化admin用户时生成的region一致；
# api地址统一采用vip，如果public/internal/admin分别使用不同的vip，请注意区分；
# cinder-api 服务类型为volume；
# cinder-api后缀为用户project-id，可通过”openstack project list”查看
# v2 public api
[root@controller01 ~]# openstack endpoint create --region RegionOne volumev2 public http://controller01:8776/v2/%\(project_id\)s

# v2 internal api
[root@controller01 ~]# openstack endpoint create --region RegionOne volumev2 internal http://controller01:8776/v2/%\(project_id\)s

# v2 admin api
[root@controller01 ~]# openstack endpoint create --region RegionOne volumev2 admin http://controller01:8776/v2/%\(project_id\)s
# v3 public api
[root@controller01 ~]# openstack endpoint create --region RegionOne volumev3 public http://controller01:8776/v3/%\(project_id\)s

# v3 internal api
[root@controller01 ~]# openstack endpoint create --region RegionOne volumev3 internal http://controller01:8776/v3/%\(project_id\)s

# v3 admin api
[root@controller01 ~]# openstack endpoint create --region RegionOne volumev3 admin http://controller01:8776/v3/%\(project_id\)s

# 在全部控制节点安装cinder服务，以controller01节点为例
[root@controller01 ~]# yum install openstack-cinder -y

# 在全部控制节点操作，以controller01节点为例；
# 注意”my_ip”参数，根据节点修改；
# 注意cinder.conf文件的权限：root:cinder
[root@controller01 ~]# cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak
[root@controller01 ~]# egrep -v "^$|^#" /etc/cinder/cinder.conf
# 在全部控制节点操作，以controller01节点为例；
# 注意”my_ip”参数，根据节点修改；
# 注意cinder.conf文件的权限：root:cinder
