Vi/etc/exports #需要在root权限下

In the file, insert the following format:

The server IP (rw,no_root_squash,sync) that requires the absolute path of the shared file to accept the file

Save File

Restart Nfs:service NFS Restart or/etc/init.d/nfs restart

Start Protmap:service protmap Restart

Log on to the server that receives the shared directory

Vi/etc/exports

Fixed IP receive placed as fixed IP

The parameters after the IP parameters are as follows:

Ro This host has read-only access to the shared directory

RW This host has read and write access to the shared directory

When the Root_squash client accesses the shared folder with the root user, the root user is mapped to an anonymous user

The root user is not mapped when the No_root_squash client accesses the shared folder with root

All_squash mapped to anonymous users when any user on the client access the shared directory

Anonuid A user who maps a user on a client to a specified local user ID

Anongid maps the user on the client to the specified local user group ID

Sync data synchronously written to memory and hard disk

Async data is staged in memory, not directly to the hard disk
