NFS volume mount (Linux)

Available in Classic.

You can mount the NFS protocol-based NAS volume that was created in NAVER Cloud Platform on the Linux server and use it.
The following describes the procedure of mounting the NAS volume on the Linux server.

1.Accessing the server
2.Installing the NFS-related package
3.Start NFS-related daemon
4.Execute mounting
5.Mount information retention settings (fstab settings)

1. Access the server

Before accessing the server, check server access preparations by referring to Prepare for server access. Once you complete the preparations for accessing the server, access the Linux server using the terminal program.

1. Run the PuTTY.
2. Enter or select the following information and click the [Open] button.
   • Host Name (or IP address): enter the public IP of the server or the fort forwarding IP for server connection (refer to the public IP and port forwarding information items in Server details).
   • Port: SSH access port (default set value: 22) or the external port set for port forwarding(refer to Set port forwarding).
   • Connection type: SSH, Telnet optional (default set value)
3. When the PuTTY Security Alert pop-up window appears, click the [Accept] button.
4. When the log-in screen is displayed, enter the account name (root) and password that were checked in the Get Admin password menu in the server (See Get Admin password).

2. Installing the NFS-related package

The following describes how to install the NFS-related package.

• CentOS 6.x and above: Download nfs-utils package

  yum install nfs-utils
  

• Ubuntu server: Download nfs-common package

  apt-get install nfs-common
  

3. Start NFS-related daemon

The following describes how to start the RPC daemon by entering the NFS start command.

1. Start the RPC daemon by entering the following command.

   • CentOS 6.x and above: Start rpcbind

     /etc/rc.d/init.d/rpcbind start
     

   • CentOS 7.x and above: Start rpcbind

     service rpcbind start
     

     or

     systemctl start rpcbind.service
     

2. Register the service so that rpcbind is automatically started when booting.

   • CentOS 6.x and above

     chkconfig rpcbind on
     

   • CentOS 7.x and above

     systemctl enable rpcbind.service
     

4. Mounting

Take the following steps to mount the NFS volume after starting the NFS-related daemon.

1. Enter the following command to create a mounting point (/mnt/nas).

   mkdir /mnt/nas
   

2. Mount the volume on the mount point with NFS v3 (/mnt/nas) using the mount information(<Example> 10.00.00.00:/n0000000_volume1) given at the time of volume creation (Refer to the Mount information item of the Detailed NAS volume page).

   mount -t nfs -o vers=3 10.00.00.00:/n0000000_volume1 /mnt/nas
   

   Note

   • When mounting NFS volume, you can do it by using NFS v3 by the below method as well.

   1. In the Editor, open the /etc/nfsmount.conf file, and release the annotation and set the version value to be 3 for the volume mount version settings (Nfsvers) as below.

   Nfsvers=3
   

   2. Mount by using mount commands.

   mount -t nfs 10.00.00.00:/n0000000_volume1 /mnt/nas
   

5. Mount information retention settings (fstab settings)

To make the Linux server maintain the mount information after rebooting the server, add the volume information to the /etc/fstab file.

When the mount information of the NFS NAS volume is 10.00.00.00:/n0000000_volume1 and the server mount point is /mnt/nas, take the following steps to add the mount information to the /etc/fstab file.

1. Open the /etc/fstab file in the editor.

   vi /etc/fstab
   

2. Press the [a] key in the editing page to enter INSERT mode and add the mount information of the volume.

   10.00.00.00:/n0000000_volume1 /mnt/nas nfs vers=3,defaults 0 0

     # Accessible filesystems, by reference, are maintained under '/dev/disk'
     # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
     #
     UUID=79ec23f4-ea9a-4f2c-a2da-xxxxxxxxxxx /     xfs     defaults      0 0
     
     # Add volume mount information ----------------------------------------
     
     10.00.00.00:/n0000000_volume1 /mnt/nas nfs vers=3,defaults 0 0
     
     # -------------------------------------------------------------
     
     
     -- INSERT --
     

3. Press the [Esc] key to stop INSERT mode and enter :wq to save changes, and then close the editor.

     :wq
     

   Note

   • You can set for mounting also by NFS v3 by the below method as well.

   1. In the Editor, open the /etc/nfsmount.conf file, and release the annotation and set the version value to be 3 for the volume mount version settings (Nfsvers) as below.

   Nfsvers=3
   

   2. In the Editor, open the /etc/fstab file to add volume mount information.

   10.00.00.00:/n0000000_volume1 /mnt/nas nfs defaults 0 0
   

   Note
