How to setup NFS/Autofs

2010-01-12T23:01:46Z

142.90.98.3: /* '''Client Config Files:''' */

== '''Server Config Files:''' ==

'''/etc/exports'''

Example:
/mountpoint client hostname/ip(rw,sync)

NFS has to be running on the server. Do not run autofs for the client on the server.

== '''Client Config Files:''' ==

'''/etc/auto.master'''

This is an automounter map and it has the following format key [ -mount-options-separated-by-comma ] location. For details of the format look at autofs.
mounts done from a hosts map will be mounted with the "nosuid" and "nodev" options unless the "suid" and "dev" options are explicitly given.

Example:
/foo /etc/auto.foo --timeout=600

'''/etc/auto.foo'''

Example:
foo -rsize=4096,soft,intr,rw server hostname/ip:/foo

NFS and autofs both have to be running on the client. NFS first, then autofs in that order.

http://www.redhat.com/docs/manuals/linux/RHL-7.3-Manual/custom-guide/s1-nfs-mount.html

== '''Both Server/Client Config Files:''' ==

Both systems must have the opposite server/client hostname or IP in the following:

'''/etc/hosts.allow'''

Example:
Server /etc/hosts.allow
ALL : client hostname or ip

Example:
Client /etc/hosts.allow
ALL : server hostname or ip
