Question

在Linux中使用 mount命令挂载NFS共享的文件夹后，可以挂载多长时间？

通过mount挂载后，在不重新启动服务器的情总下怎么让它永不断开？

Answer 1

默认你不卸载是不会断开的，除非你重启了操作系统
如果想让他开机自动挂载的话需要把挂载信息写入到/etc/fstab里去

Answer 2

Mounting NFS Filesystems
● Makes a remote NFS filesystem work as though it
were a local filesystem
● /etc/fstab can be used to specify persistent
network mounts
● NFS shares are mounted at boot time by /etc/
init.d/netfs
● Exports can be mounted manually with the
mount command.
# mkdir /mnt/server1
# mount -t nfs server1:/var/ftp/pub /mnt/server1

Automounter
● System administrator specifies mount points
controlled by automounter daemon process in /
etc/auto.master
● The automounter monitors access to these
directories and mounts the filesystem on demand
● Filesystems automatically unmounted after a
specified interval of inactivity
● Enable the special map -host to “browse” all
NFS exports on the network
● Supports wildcard directory names

Direct Maps
● Direct maps include absolute path names
● Does not obscure local directory structure
● Example:
/etc/auto.master:
/- /etc/auto.direct
/etc/auto.direct:
/foo server1:/export/foo
/usr/local/ server1:/usr/local

我刚好看资料 看到这些，具体的我还没有试验 希望可以帮到你吧
