Editor to share with you how to install nfs in Suse 10, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

one。 Server side

a. Check whether nfs is installed: rpm-qa | grep nfs & & rpm-qa | grep portmap (with installed nfs-utils 1.0)

Modify configuration file / etc/exports

E.g. / var/log/nfs 192.168.0.3 (rw,sync,no_root_squash) (without no_root_squash, the client side will not be able to use root mount (reason given by server: Permission denied). Try again to remove no_root_squash and restart.

2.nfsserver, root mount is available. Need to study) several files related to NFS, commands

A, / etc/exports

Access to NFS volumes is approved by exports, which enumerates several hostnames that have access to file systems on NFS servers.

B, / sbin/exportfs

Maintain NFS resource sharing. You can use it to reset the shared directory of / etc/exports, uninstall the shared directory of NFS Server, or re-share.

C, / usr/sbin/showmount

It is used on the NFS Server side, while showmount is mainly used on the Client side. Showmount can be used to view directory resources shared by NFS.

D, / var/lib/nfs/xtab

NFS record document: it allows you to see which Client is connected to the NFS host.

The following are not directly responsible for NFS, in fact they are responsible for all RPC

E, / etc/default/portmap

In fact, portmap is responsible for mapping all RPC service ports, and its content is very simple (more on this later).

F, / etc/hosts.deny

Set the host that denies portmap service

G, / etc/hosts.allow

Set the hosts that allow portmap services

1. The specific parameters are as follows:

Rw: can write permissions

Ro: read-only permission

No_root_squash: if you log in to the shared directory of the NFS host, if you are a root user, then the permission is also root, but this is not secure.

Root_squash: if the logged-in user is root, its permissions will become nobody

All_squash: no matter what the logged-in user is, the user has the right of anonymous user.

Sync: data is synchronously written to hard disk and memory

Async: data is temporarily stored in memory instead of being written to the hard disk

Anounid: you can set your own uid, but it must be the same as the user uid in the / etc/passwd directory

Anongid: same as anonuid, but becomes group id

2. / etc/hosts.deny

Portmap:ALL

Lockd:ALL

Mountd:ALL

Rquotad:ALL

Statd:ALL

/ etc/hosts.allow

Portmap: 192.168.0.1, 192.168.0.2

Lockd: 192.168.0.1, 192.168.0.2

Rquotad: 192.168.0.1, 192.168.0.2

Mountd: 192.168.0.1, 192.168.0.2

Statd: 192.168.0.1, 192.168.0.2

3. Start the service

Service portmap start

Service nfsserver start

4. Rpcinfo-p localhost can view service information (nfs,)

Showmount [- ae] localhost shows whether it is mounted or not

Nfsstat provides statistics on the operation of NFS. Including client-side RPC and NFS statistics, as well as server-side RPC and NFS statistics.

Exportfs [- aruv] exportfs to re-scan the / etc/exports file without restarting the nfs service

Parameter description:

-a: settings for mounting (or uninstalling) all / etc/exports files

-r: set from the newly mounted / etc/exports, in addition, synchronously update the contents of / etc/exports and / var/lib/nfs/xtab

-u: uninstall a directory

-v: displays the shared directory on the screen on export

two。 Client

Service portmap start

Mount-o nolock-t nfs:/home/lqm / mnt/nfs

Mount-t nfs-o rsize=1024,wsize=1024,timeo=3,udp 192.168.0.3:/var/log/nfs / var/tmp

Automatically load the NFS server export directory at startup: vi / etc/fstab

192.168.0.3:/var/log/nfs / mnt nfs rsize=8192,wsize=8192,timeo=14,intr

192.168.0.3:/tmp / mnt/nfs nfs defaults 0 0
