安装cinder和nfs
yum install -y openstack-cinder yum install cifs-utils 在controller节点配置nfs[[email?protected] ~]# mkdir -p /data/nfs #创建一个共享挂载资源的目录 [[email?protected] ~]# cat /etc/exports /data/nfs *(rw,sync,root_squash) #NFS服务程序的配置文件为/etc/exports sync 同时将数据写入到内存与硬盘中，保证不丢失数据 rw 读写 no_root_squash 当NFS客户端以root管理员访问时，映射为NFS服务器的root管理员 启动和启用NFS服务程序。由于在使用NFS服务进行文件共享之前，需要使用RPC（Remote Procedure Call，远程过程调用）服务将NFS服务器的IP地址和端口号等信息发送给客户端。因此，在启动NFS服务之前，还需要顺带重启并启用rpcbind服务程序，并将这两个服务一并加入开机启动项中[[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命令查询NFS服务器的远程共享信息[[email?protected] ~]# showmount -e 192.168.100.10 Export list for 192.168.100.10: /data/nfs * 测试挂载[[email?protected] ~]# mount 192.168.100.10:/data/nfs /mnt/ 192.168.100.10:/data/nfs nfs4 197G 19G 169G 10% /mnt #挂载成功 [[email?protected] ~]# umount /mnt/ [[email?protected] ~]# df -Th Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/centos-root ext4 2.9T 1.8G 2.8T 1% / devtmpfs devtmpfs 7.8G 0 7.8G 0% /dev tmpfs tmpfs 7.8G 0 7.8G 0% /dev/shm tmpfs tmpfs 7.8G 17M 7.8G 1% /run tmpfs tmpfs 7.8G 0 7.8G 0% /sys/fs/cgroup /dev/md126p2 xfs 495M 129M 367M 27% /boot tmpfs tmpfs 1.6G 0 1.6G 0% /run/user/0 配置nfs作为cinder后端存储[[email?protected] ~]# vi /etc/cinder/cinder.conf [DEFAULT] volume_driver = cinder.volume.drivers.nfs.NfsDriver nfs_shares_config = /etc/cinder/nfs.conf 去创建/etc/cinder/nfs.conf这个文件[[email?protected] ~]# vi /etc/cinder/nfs.conf 192.168.100.10:/data/nfs 重启服务nfs后端存储自动挂载[[email?protected] ~]# systemctl restart openstack-cinder-api.service [[email?protected] ~]# systemctl restart openstack-cinder-volume.service [[email?protected] ~]# systemctl restart openstack-cinder-scheduler.service [[email?protected] ~]# df -Th Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/centos-root ext4 197G 19G 169G 10% / devtmpfs devtmpfs 7.8G 0 7.8G 0% /dev tmpfs tmpfs 7.8G 0 7.8G 0% /dev/shm tmpfs tmpfs 7.8G 8.7M 7.8G 1% /run tmpfs tmpfs 7.8G 0 7.8G 0% /sys/fs/cgroup /dev/sda1 xfs 494M 126M 368M 26% /boot /dev/loop0 iso9660 4.1G 4.1G 0 100% /opt/centos /dev/loop1 iso9660 2.7G 2.7G 0 100% /opt/iaas tmpfs tmpfs 1.6G 0 1.6G 0% /run/user/0 192.168.100.10:/data/nfs nfs4 197G 19G 169G 10% /var/lib/cinder/mnt/cfee723fff086429eb82121076ac5407 创建volume测试[[email?protected] ~]# cinder create --display-name ‘volume‘ 1
