2.1 Exported directory for nfsroot

  • no_root_squash will use UID and GID of client for file access by client.
  • If UID and GID is shared by LDAP, use no_root_squash.
  • If using nfsroot for booting root filesystem, use no_root_squash.
  • subtree_check checks if file access by client is inside exported directory. no_subtree_check disable this check for performance.

$ cat /etc/exports/srv/nfsroot 192.168.11.0/24(rw,sync,no_root_squash,no_subtree_check)$ sudo mkdir /srv/nfsroot$ sudo exportfs -ra

2.2 Exported directory for file sharing

  • root_squash uses nobody:nogroup for file access by client.

$ cat /etc/exports/srv/nfsshare *(rw,sync,root_squash,subtree_check)$ sudo mkdir /srv/nfsshare$ sudo chmod 777 /srv/nfsshare$ sudo exportfs -ra
