network Environment

Server RHEL7 : 192.168.222.1

Client RHEL7 : 192.168.222.222

Server-side configuration NFS

Yum Install Nfs-utils

Configuration:

Mkdir/mnt/hrr

chmod 777/MNT/HRR

* : If you use/MNT/HRR as a shared directory, do not change permissions if you use other such as/home as a shared directory, which can cause permissions problems and compromise the system hierarchy.

Start the service and add it to the startup directory:

Systemctl Enable Rpcbind

Systemctl Enable Nfs-server

Systemctl Enable Nfs-lock

Systemctl Enable Nfs-idmap

Systemctl Start Rpcbind

Systemctl Start Nfs-server

Systemctl Start Nfs-lock

Systemctl Start Nfs-idmap

Modify the profile share/MNT/HRR and/home:

Vim/etc/exports

Write:

/MNT/HRR 192.168.222.0/24 (Rw,sync,no_root_squash,no_all_squash)

The following table is the permissions parameter for common/etc/exports profiles, please man exports for details

Parameter values	Content Description
RW
sync means the data is written synchronously to the memory and hard disk, and async means that the data is staged in memory, not directly to disk

Anonuid Anongid	Anon refers to Anonymous (anonymous user) in front of the *_squash mentioned by the anonymous user UID setting value, usually nobody (nfsnobody), but you can set the value of this UID, of course, this UID must exist/etc/ Among the passwd.
