挂载NAS存储并查看挂载信息
root@localhost:~# mount -t nfs -o vers=4.0 9999f94a9b0-biz99.cn-hongkong.nas.aliyuncs.com:/ /data root@localhost:~# df -h Filesystem Size Used Avail Use% Mounted on udev 2.0G 0 2.0G 0% /dev tmpfs 396M 2.8M 393M 1% /run /dev/vda1 99G 2.7G 91G 3% / tmpfs 2.0G 0 2.0G 0% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup tmpfs 396M 0 396M 0% /run/user/0 9999f94a9b0-biz99.cn-hongkong.nas.aliyuncs.com:/ 1.0P 0 1.0P 0% /data root@localhost:~#
设置NFS在系统启动时自动挂载
root@localhost:~# vi /etc/fstab 9999f94a9b0-biz99.cn-hongkong.nas.aliyuncs.com:/ /data nfs auto,nofail,noatime,nolock,intr,tcp,actimeo=1800 0 0
手动挂载和自动挂载mount输出的差异
