 We also want to export to a couple of running virtuals to store large amounts of data. Since they have public interfaces, we need to set up our nfs server to only allow limited access to our nfs server, both by limiting through nfs and also with firewalls. We also want to export to a couple of running virtuals to store large amounts of data.

 +===== Devuan (Debian) =====
 +
 +Linux does not, by default, install an nfs server. To install (Devuan, Debian derivative)
 +
 +<code bash>
 +apt install -y nfs-kernel-server
 +</code>
 +
 +Also, the syntax for /etc/exports is slightly different for nfs v2 and 3
 +<code>
 +/srv/nfs 192.0.2.10(rw,sync,no_subtree_check,no_root_squash)
 +</code>
 +
 +And the way to start/restart nfsd is
 +
 +<code bash>
 +exportfs -ra # re-export filesystems
 +exportfs -v # view exports
 +/etc/init.d/nfs-kernel-server restart
 +</code>

 Note the mountd_flags entry. mountd is what actually handles the mount request from clients. The -r flag allows individual files to be mounted, such as swap a swap file, or a virtual image. Additional flags may be specified. See //man 5 mountd// for more information. Two nice ones are the -h and -p flags which allow you to specify the IP and Port mountd will listen on. Note the mountd_flags entry. mountd is what actually handles the mount request from clients.

 +===== Maintenance =====
 +
 +If you need to add/remove/modify the NFS shares, create/modify any file systems on the server, then add/edit the appropriate stanzas to /etc/exports. Once you have done that, tell mountd to re-read the configuration:
 +<code bash>
 +service mountd reload
 +</code>
  
 +At this point, the modifications will be in effect. NOTE, if you have modified a share which was mounted, you should umount it, make the changes, then remount.
