1.Cinder使用NFS作为后端存储
搭建Cinder服务详细细节参考次文章https://www.xionghaier.cn/archives/564.html
此处不再做演示
1.1控制节点安装Cinder服务
此处安装步骤省略
[root@controller ~]# cat /etc/cinder/cinder.conf [DEFAULT] transport_url = rabbit://openstack:openstack@118.190.201.11 auth_strategy = keystone iscsi_ip_address = 118.190.201.11 [BACKEND] [BRCD_FABRIC_EXAMPLE] [CISCO_FABRIC_EXAMPLE] [COORDINATION] [FC-ZONE-MANAGER] [KEYMGR] [cors] [cors.subdomain] [database] connection = mysql+pymysql://cinder:cinder@118.190.201.11/cinder [keystone_authtoken] auth_uri = http://118.190.201.11:5000 auth_url = http://118.190.201.11:35357 memcached_servers = 118.190.201.11:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = cinder password = cinder [matchmaker_redis] [oslo_concurrency] lock_path = /var/lib/cinder/tmp [oslo_messaging_amqp] [oslo_messaging_notifications] [oslo_messaging_rabbit] [oslo_middleware] [oslo_policy] [oslo_reports] [oslo_versionedobjects] [ssl] [lvm] volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver volume_group = cinder-volumes iscsi_protocol = iscsi iscsi_helper = lioadm
1.2计算节点安装Cinder服务
[root@compute1 ~]# yum install openstack-cinder targetcli python-keystone -y
1.3安装NFS服务
[root@compute1 ~]# yum install -y nfs-utils rpcbind
1.4创建挂载目录
[root@compute1 ~]# mkdir -p /data/nfs #共享目录 [root@compute1 ~]# cat /etc/exports /data/nfs *(rw,no_root_squash,) #启动服务 [root@compute1 ~]# systemctl start rpcbind [root@compute1 ~]# systemctl start nfs
1.5Cider计算节点配置文件内容
[root@compute1 ~]# cat /etc/cinder/cinder.conf [DEFAULT] transport_url = rabbit://openstack:openstack@118.190.201.11 auth_strategy = keystone iscsi_ip_address = 118.190.201.31 enabled_backends = lvm glance_api_servers = http://118.190.201.11:9292 [BACKEND] [BRCD_FABRIC_EXAMPLE] [CISCO_FABRIC_EXAMPLE] [COORDINATION] [FC-ZONE-MANAGER] [KEYMGR] [cors] [cors.subdomain] [database] connection = mysql+pymysql://cinder:cinder@118.190.201.11/cinder [keystone_authtoken] auth_uri = http://118.190.201.11:5000 auth_url = http://118.190.201.11:35357 memcached_servers = 118.190.201.11:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = cinder password = cinder [matchmaker_redis] [oslo_concurrency] lock_path = /var/lib/cinder/tmp [oslo_messaging_amqp] [oslo_messaging_notifications] [oslo_messaging_rabbit] [oslo_middleware] [oslo_policy] [oslo_reports] [oslo_versionedobjects] [ssl]
在/etc/cinder/cinder.conf下
添加[nfs]配置文件
[nfs]
volume_driver = cinder.volume.drivers.nfs.NfsDriver
nfs_shares_config = /etc/cinder/nfs_shares
nfs_mount_point_base = $state_path/mnt #state_path=/var/lib/cinder
注释说明：
#nfs配置思路
[root@compute1 drivers]# cd /usr/lib/python2.7/site-packages/cinder/volume/drivers/
[root@compute1 drivers]# ls nfs*
nfs.py nfs.pyc nfs.pyo
创建共享文件
vim /etc/cinder/nfs_shares
118.190.201.31:/data/nfs
#修改权限
chown root:cinder /etc/cinder/nfs_shares
chmod 640 /etc/cinder/nfs_shares
修改cinder配置文件
把enabled_backends = lvm修改为enabled_backends = nfs
1.6启动服务
systemctl enable openstack-cinder-volume systemctl start openstack-cinder-volume
1.7创建存储类型
因为之前有LVM现在有NFS，它不知道要用那个所有需要创建
[root@controller ~]# cinder type-create NFS [root@controller ~]# cinder type-create ISCSI #在控制节点的[lvm]下添加 volume_backend_name = ISCSI-Storage #重新启动 systemctl restart openstack-cinder-volume #计算节点在[nfs]下添加 volume_backend_name = NFS-Storage #重启 systemctl restart openstack-cinder-volume
1.8设置卷类型
[root@controller ~]# cinder type-key NFS set volume_backend_name=ISCSI-Storage [root@controller ~]# cinder type-key NFS set volume_backend_name=NFS-Storage
