When No_root_squash:nfs client connects to the server, if root is used, then the directory shared by the server also has root privileges. Obviously it's not safe to open this.

When Root_squash:nfs client connects to the server, if root is used, then the directory shared by the server has anonymous user rights, usually he will use nobody or nfsnobody identity;

All_squash: No matter what user the NFS client connects to the server, it has anonymous user rights to the directory shared by the server;

Anonuid: The UID value of an anonymous user, usually a nobody or nfsnobody, where you can set it yourself;

Anongid: The GID value of the anonymous user.
