openstack安装（liberty）
八、安装块存储服务（Block Storage service/cinder） ###注意注意注意时间同步很重要8.1安装环境准备中配置主机相应配置，包括主机名称，hosts，时间同步，防火墙，SELINUX以及相关OPENSTACK包
8.2控制节点配置
8.2.1创建数据库并授权
# mysql -uroot -p
Enter password:
MariaDB [(none)]> create database cinder;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> grant all privileges on cinder.* to 'cinder'@'localhost' identified by 'cinder';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> grant all privileges on cinder.* to 'cinder'@'%' identified by 'cinder'; 8.2.2创建用户并添加角色和项目
# . admin-openrc.sh
# openstack user create --domain default --password-prompt cinder
User Password:
Repeat User Password:
+-----------+----------------------------------+

8.2.6配置计算节点使用块存储
# vi /etc/nova/nova.conf
os_region_name = RegionOne
8.2.7启动服务并配置自动启动
# systemctl restart openstack-nova-api.service
# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
8.3配置block1（cinder）节点
8.3.1安装并启动LVM服务
# yum install lvm2
# systemctl is-enabled lvm2-lvmetad
disabled
# systemctl enable lvm2-lvmetad.service
Created symlink from /etc/systemd/system/sysinit.target.wants/lvm2-lvmetad.service to /usr/lib/systemd/system/lvm2-lvmetad.service.
# systemctl start lvm2-lvmetad.service
# systemctl is-enabled lvm2-lvmetad

8.3.3配置LVM过滤
8.3.3.1如果块存储节点或计算节点OS磁盘有使用LVM，需做同样配置。
# vi /etc/lvm/lvm.conf##块存储节点
devices {
...
filter = [ "a/sda/", "a/sdb/", "r/.*/"]
...
}
# vi /etc/lvm/lvm.conf##计算节点
devices {
...
filter = [ "a/sda/", "r/.*/"]
...
}
8.3.3.2如果块存储节点或计算节点OS磁盘没有使用LVM，则仅需如下配置
# vi /etc/lvm/lvm.conf##块存储节点
devices {
...
filter = [ "a/sdb/", "r/.*/"]
...
}
8.3.4安装配置组件
# yum install openstack-cinder targetcli python-oslo-policy -y
# vi /etc/cinder/cinder.conf
connection = mysql://cinder:cinder@controller1/cinder
rpc_backend = rabbit
rabbit_host = controller1
rabbit_userid = openstack
rabbit_password = openstack
auth_strategy = keystone
auth_uri = http://controller1:5000
auth_url = http://controller1:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = cinder
my_ip = 10.0.0.41
####注意注意注意，配置文件中没有配置组，需要创建，不能修改现有配置，否则云盘无法挂载到实例
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm
enabled_backends = lvm
glance_host = controller1
lock_path = /var/lib/cinder/tmp
verbose = True
8.3.5启动服务并设置自启动
# systemctl enable openstack-cinder-volume.service target.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-cinder-volume.service to /usr/lib/systemd/system/openstack-cinder-volume.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/target.service to /usr/lib/systemd/system/target.service.
# systemctl start openstack-cinder-volume.service target.service
# systemctl status openstack-cinder-volume.service target.service
8.4验证
# . admin-openrc.sh
# cinder service-list
