Configuring the Linux NFS Server

Configuring the Linux NFS Server

After the Linux NFS server is configured, configurations of the key management server will be backed up to the Linux NFS server.


Suites related to the NFS service have been installed on the Solaris server.


  1. Log in to the Linux NFS server.
  2. Run the useradd command to create the backup user.

    For example, under the /home directory, create a user kauser, and specify the user ID of this user to 710.

    # useradd -d /home/kauser -u 710 kauser

  3. Create the backup directory and check the status of the NFS service.

    1. Create a directory for saving backup information about the keyAuthority server.
      # mkdir -p /kabackup 
      # chown kauser /kabackup 
      # chgrp kauser /kabackup 
      # chmod 700 /kabackup
    2. Check the version of the installed NFS service suite.
      # rpm -qa | grep nfs 

      The displayed version might be different.

      If no message is returned after the command is run, it indicates that the NFS service suite has not been installed. Ensure that the Linux server is connected with the Internet, and run the yum command to install suites related to the NFS service.

      # yum install nfs-utils

      After installation, run the service command to enable the NFS service.

      # service nfs start 
      Starting NFS services: [ OK ] 
      Starting NFS quotas: [ OK ] 
      Starting NFS daemon: [ OK ] 
      Starting NFS mountd: [ OK ] 
      # service nfs status 
      rpc.mountd (pid 3003) is running... 
      nfsd (pid 3000 2999 2998 2997 2996 2995 2994 2993) is running... 
      rpc.rquotad (pid 2989) is running... 
    3. Ensure that the NFS service is running properly.
      rpcinfo -p 
      100000 4 tcp 111 portmapper 
      100000 3 tcp 111 portmapper 
      100000 4 udp 111 portmapper 
      100000 3 udp 111 portmapper 
      100000 2 udp 111 portmapper 
      100024 1 udp 12562 status 
      100024 1 tcp 12562 status 
      100005 1 udp 42760 mountd 
      100005 1 tcp 42760 mountd 
      100005 2 udp 42760 mountd 
      100005 2 tcp 42760 mountd 
      100005 3 udp 42760 mountd 
      100005 3 tcp 42760 mountd 
      100003 3 tcp 2049 nfs 
      100003 4 tcp 2049 nfs 
      100003 3 udp 2049 nfs 
      100003 4 udp 2049 nfs 
      100021 3 udp 52293 nlockmgr 
      100021 4 udp 52293 nlockmgr 
      100021 3 tcp 52293 nlockmgr 
      100021 4 tcp 52293 nlockmgr 

  4. Creates an NFS share.

    1. Create a folder for exporting data.

      In the /etc/exports file, add the host IP addresses or names of the keyAuthority key management servers.

      • Add the IP addresses of the key management servers.
      • Add the names of the key management servers.
    2. Create an export task.
      #exportfs -a
    3. Verify that the export task is successfully created.
      #exportfs -v 
    4. Restart the NFS service.
      # service nfs restart 
      Shutting down NFS mountd: [ OK ] 
      Shutting down NFS daemon: [ OK ] 
      Shutting down NFS services: [ OK ] 
      Starting NFS services: [ OK ] 
      Starting NFS daemon: [ OK ] 
      Starting NFS mountd: [ OK ]
