[Linux] Network File System(NFS) 설정하기

Edit exports setting for nfs on your host server and restart NFS server.

sudo apt-get install nfs-kernel-server
sudo vim /etc/exports
/nfsroot        192.168.0.0/24(rw,no_subtree_check,no_root_squash,async,insecure)
/home           192.168.0.0/24(rw,sync,no_subtree_check,no_root_squash)

sudo /etc/init.d/nfs restart
sudo service nfs-kernel-server restart

There are some permission options.

• no_root_squash
  • Map requests from uid/gid 0 to the anonymous uid/gid. Note that this does not apply to any other uids that might be equally sensitive, such as user bin.
• root_squash
  • Turn off root squashing. This option is mainly useful for diskless clients.
• all_squash
  • Map all uids and gids to the anonymous user. Useful for NFS-exported public FTP directories, news spool directories, etc. The opposite option is no_all_squash, which is the default setting.
• anonuid and anongid
  • These options explicitly set the uid and gid of the anonymous account. This option is primarily useful for PC/NFS clients, where you might want all requests appear to be from one user. As an example, consider the export entry for /home/joe in the example section below, which maps all requests to uid 150 (which is supposedly that of user joe).

Examples:

/home           192.168.0.1/24(rw,sync,no_subtree_check,all_squash,anonuid=3000,anongid=3000)

If you use all_squash option with anonuid and anongid, all remote your became the 1001 user and join the group 1001.

Edit fstab setting on your client server.

sudo apt-get install nfs-common
sudo mount -t nfs -o nolock 192.168.0.1:/home /home

Then, fstab file in your client server will be:

sudo vim /etc/fstab
# <file system>                 <mount point>   <type>  <options>       <dump>  <pass>
192.168.0.100:/nfsroot          /               nfs     sync,ro,hard,intr,nolock        0       0
192.168.0.100:/home             /home           nfs     sync,rw,hard,intr,nolock        0       2
