CentOS 7.4 NFS Auto-Mount
On-Demand Auto-Mount
Automatically mount NFS shared directory /home/share to local path /mnt/share upon user login
yum install -y autofs
vi /etc/auto.master
/mnt /etc/auto.conf（这个配置文件本身就没有要自己创建）
vi /etc/auto.conf
share 192.168.1.22:/etc/letsencrypt/live/margrop.net-0001/（nfs服务器上共享文件）
service autofs restart
Restart the Service
Restart the virtual machine and restart the service
service autofs restart
cd /mnt
ls
#此时看到不到share这个目录
Manually create it again
mkdir -p /mnt/share
Now
cd /mnt
ls
#会看到share这个目录
Running ls again will display the shared files
Run df -h to check mount information
Permanent Auto-Mount
vim /etc/fstab
192.168.65.10:/home/share /mnt/share nfs defaults 0 0
