2 Export directory to NFS

/etc/exportfs is written exported directories to NFS.

> cat /etc/exports<path> <ipaddr>(<option>)

Update exported directories to NFS.

> sudo exportfs -ra

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,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
