安裝cinder和nfs

yum install -y openstack-cinder

yum install cifs-utils

在controller節點配置nfs

[[email?protected] ~]# mkdir -p /data/nfs #創建一個共享掛載資源的目錄

[[email?protected] ~]# cat /etc/exports

/data/nfs *(rw,sync,root_squash) #NFS服務程序的配置文件為/etc/exports sync 同時將數據寫入到內存與硬盤中，保證不丟失數據 rw 讀寫 no_root_squash 當NFS客戶端以root管理員訪問時，映射為NFS服務器的root管理員

啟動和啟用NFS服務程序。由于在使用NFS服務進行文件共享之前，需要使用RPC(Remote Procedure Call，遠程過程調用)服務將NFS服務器的IP地址和端口號等信息發送給客戶端。因此，在啟動NFS服務之前，還需要順帶重啟并啟用rpcbind服務程序，并將這兩個服務一并加入開機啟動項中

[[email?protected] ~]# systemctl resatrt rpcbind

[[email?protected] ~]# systemctl enable rpcbind

[[email?protected] ~]# systemctl start nfs-server

[[email?protected] ~]# systemctl enable nfs-server

使用showmount命令查詢NFS服務器的遠程共享信息

[[email?protected] ~]# showmount -e 192.168.100.10

Export list for 192.168.100.10:

/data/nfs *

測試掛載

配置nfs作為cinder后端存儲

[[email?protected] ~]# vi /etc/cinder/cinder.conf

[DEFAULT]

volume_driver = cinder.volume.drivers.nfs.NfsDriver

nfs_shares_config = /etc/cinder/nfs.conf

去創建/etc/cinder/nfs.conf這個文件

[[email?protected] ~]# vi /etc/cinder/nfs.conf

192.168.100.10:/data/nfs

重啟服務nfs后端存儲自動掛載

[[email?protected] ~]# systemctl restart openstack-cinder-api.service
