Installing and Configring NFS Server step by step Part 1

Installing and Configring NFS Server step by step

Follow these steps to install an NFS server.

Step 1. To begin the NFS server setup, install the required packages:

# yum install -y nfs-utils nfs4-acl-tools

Step 2. Verify the package installation:

# rpm -qa | grep nfs

nfs4-acl-tools-0.3.3-5.el6.x86_64

nfs-utils-1.2.2-7.el6.x86_64

nfs-utils-lib-1.1.5-1.el6.x86_64

Step 3. The NFS server uses three different services to function properly. You need to enable them all at boot for the NFS server to function the way

it should:

# chkconfig nfs on

# chkconfig nfslock on

# chkconfig rpcbind on

Step 4. Verify that all three services are set to start on system boot:

# chkconfig --list nfs

nfs      0:off 1:off 2:on 3:on 4:on 5:on 6:off

# chkconfig --list nfslock

nfslock 0:off 1:off 2:on 3:on 4:on 5:on 6:off

# chkconfig --list rpcbind

netfs 0:off 1:off 2:on 3:on 4:on 5:on 6:off

You should also verify that the NFS service is currently stopped because you need to make some configuration changes before you can start it.

Step 5. Verify that the service is off:

# service nfs status

rpc.mountd is stopped

nfsd is stopped

rpc.rquotad is stopped

Configuring NFS

For the first configuration step, you need to make a few changes to the main config file.

Step 1. Open the main config file for editing:

# nano /etc/sysconfig/nfs

Step 2. Uncomment the following lines:

MOUNTD_NFS_V1=”no”

MOUNTD_NFS_V2=”no”

MOUNTD_NFS_V3=”no”

RPCNFSDARGS=”-N 2 -N 3”

The first three lines disable the mountd daemon from accepting anything below version 4. The last line disables the NFS service from even advertising anything but version 4 as well.

Step 3. Save the file and exit.

Next, let’s work with the /etc/exports file because this defines what resources will be available to your clients. If the file doesn’t exist already, you can create it. The syntax of the /etc/exports file is <mountpoint> <host><permissions/options>

Step 4. Set up your exports in the /etc/exports files to be available to any client on the network:

# nano /etc/exports

/home                                   *(ro,sync)

/opt/company_data         *(rw,sync)

Here, you define two resources that you will make available. The first line defines the /home directory to be exported and allows read-only access to all clients. The second line provides the /opt/company_data directory to all of your clients with read and write permissions. After you finish defining all the resources you want to export, save and close the file.

Step 5. Start the two NFS services (rpcbindshould be running already by default):

# service nfslock start

Starting NFS statd:                         [ OK ]

# service nfs start

Starting NFS services:                   [ OK ]

Starting NFS quotas:                     [ OK ]

Starting NFS daemon:                   [ OK ]

Starting NFS mountd:                   [ OK ]

Step 6: Verify that the services have started successfully:

# service rpcbind status

rpcbind (pid 25068) is running...

# service nfslock status

rpc.statd (pid 17726) is running...

# service nfs status

rpc.svcgssd is stopped

rpc.mountd (pid 17780) is running...

nfsd (pid 17777 17776 17775 17774 17773 17772 17771 17770) is

running...

rpc.rquotad (pid 17764) is running...
