  • 基于OpenStack构建企业私有云(8)Cinder

    控制节点部署

    1.Cinder安装

    [root@linux-node1 ~]# yum install -y openstack-cinder


    2.数据库配置

    [root@linux-node1 ~]# vim /etc/cinder/cinder.conf
    #在 [database] 部分,配置数据库访问。
    connection=mysql+pymysql://cinder:cinder@192.168.56.11/cinder
    同步数据库
    [root@linux-node1 ~]# su -s /bin/sh -c "cinder-manage db sync" cinder
    验证数据库状态
    [root@linux-node1 ~]# mysql -h 192.168.56.11 -ucinder -pcinder -e "use cinder;show tables;"


    3.Keystone相关配置

    [root@linux-node1 ~]# vim /etc/cinder/cinder.conf
    [DEFAULT]
    auth_strategy=keystone
    [keystone_authtoken]
    auth_uri = http://192.168.56.11:5000
    auth_url = http://192.168.56.11:35357
    memcached_servers = 192.168.56.11:11211
    auth_type = password
    project_domain_name = default
    user_domain_name = default
    project_name = service
    username = cinder
    password = cinder
    


    4.RabbitMQ相关配置

    [root@linux-node1 ~]# vim /etc/cinder/cinder.conf
    [DEFAULT]
    transport_url = rabbit://openstack:openstack@192.168.56.11


    5.其它配置

    在 [oslo_concurrency] 部分,配置锁路径:
    [oslo_concurrency]
    lock_path = /var/lib/cinder/tmp


    6.配置Nova以使用块设备存储,注意所有

        编辑文件 /etc/nova/nova.conf 并添加如下到其中:
    [cinder]
    os_region_name = RegionOne


    7.重启nova-api服务

    [root@linux-node1 ~]# systemctl restart openstack-nova-api.service


    8.启动cinder服务,并设置为开机自动启动。

    # systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
    # systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service


    9.Cinder注册Service和Endpoint

    # 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://192.168.56.11:8776/v2/%(project_id)s
    # openstack endpoint create --region RegionOne 
      volumev2 internal http://192.168.56.11:8776/v2/%(project_id)s
    # openstack endpoint create --region RegionOne 
      volumev2 admin http://192.168.56.11:8776/v2/%(project_id)s
     
    # openstack endpoint create --region RegionOne 
      volumev3 public http://192.168.56.11:8776/v3/%(project_id)s
    # openstack endpoint create --region RegionOne 
      volumev3 internal http://192.168.56.11:8776/v3/%(project_id)s
     # openstack endpoint create --region RegionOne 
      volumev3 admin http://192.168.56.11:8776/v3/%(project_id)s


    存储节点配置
    对于CentOS环境,默认是已经安装了LVM。如果没有可以使用以下命令安装并启动。
        安装 LVM 包:

    [root@linux-node1 ~]# yum install -y lvm2 device-mapper-persistent-data


        启动LVM的metadata服务并且设置该服务随系统启动:

    [root@linux-node1 ~]# systemctl enable lvm2-lvmetad.service
    [root@linux-node1 ~]# systemctl start lvm2-lvmetad.service


    把/dev/sdb创建为LVM的物理卷:

    [root@linux-node2 ~]# pvcreate /dev/sdb
      Physical volume "/dev/sdb" successfully created



    创建名为cinder-volumes的逻辑卷组

    [root@linux-node2 ~]# vgcreate cinder-volumes /dev/sdb
      Volume group "cinder-volumes" successfully created

    [root@linux-node2 ~]# vim /etc/lvm/lvm.conf
        在``devices``部分,添加一个过滤器,只接受``/dev/sdb``设备,拒绝其他所有设备:
        devices {
        ...
        filter = [ "a/sdb/", "r/.*/"]
        filter = [ "a/sda/", "a/sdb/", "r/.*/"]
        filter = [ "a/sda/", "r/.*/"]


    存储节点安装

       存储节点安装和控制节点类型,还是分为两步:
    1.    软件安装。
    2.    从控制节点SCP配置文件。
    安装isci-target和cinder

    [root@linux-node2 ~]# yum install -y openstack-cinder targetcli python-keystone


    同步控制节点配置文件
    由于存储节点大多数配置和控制节点相同,可以直接使用控制节点配置好的cinder.conf。再此基础上进行小的变动。

    [root@linux-node1 ~]# scp /etc/cinder/cinder.conf 192.168.56.12:/etc/cinder/


    设置Cinder后端驱动
    [root@linux-node2 ~]# vim /etc/cinder/cinder.conf

    [lvm]
    volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
    volume_group = cinder-volumes
    iscsi_protocol = iscsi
    iscsi_helper = lioadm
    volume_backend_name=iSCSI-Storage


    在 [DEFAULT] 部分,启用 LVM 后端:

    [DEFAULT]
    ...
    enabled_backends = lvm
    
    
    [DEFAULT]
    glance_api_servers = http://192.168.56.11:9292


    启动块存储卷服务及其依赖的服务,并将其配置为随系统启动:

     # systemctl enable openstack-cinder-volume.service target.service
     # systemctl start openstack-cinder-volume.service target.service
