15.2. NFS Client Configuration

CentOS 6 NFSv3 portmap 已经不存,已经被rpcbind替代

chkconfig rpcbind on
service rpcbind start
		

test nfs

mount 172.16.1.10:/exports /mnt
			

NFSv4

mount -t nfs4 -o ro,intr 172.16.1.10:/ /mnt
		
umount /mnt
		

过程 15.3. On the *CLIENT* side

  1. Mounting NFS File Systems using /etc/fstab

    The general syntax for the line in /etc/fstab is as follows:

    server:/usr/local/pub    /pub   nfs    rsize=8192,wsize=8192,timeo=14,intr
    				

    NFSv4

    server:/ /mount/point nfs4 rw,hard,intr,proto=tcp,port=2049,auto 0 0
    				
  2. mount all stuff from /etc/fstab

    # mount -a
    				
  3. rpcinfo

    rpcinfo -p
       program vers proto   port
        100000    2   tcp    111  portmapper
        100000    2   udp    111  portmapper
        100024    1   udp    707  status
        100024    1   tcp    710  status
        100021    1   udp  48233  nlockmgr
        100021    3   udp  48233  nlockmgr
        100021    4   udp  48233  nlockmgr
        100021    1   tcp  58065  nlockmgr
        100021    3   tcp  58065  nlockmgr
        100021    4   tcp  58065  nlockmgr
    				
  4. start required services

    centos 5.x

    chkconfig portmap on
    service portmap start
    				

    centos 6

    chkconfig rpcbind on
    service rpcbind start
    				

15.2.1. Using NFS over UDP

For example, on demand via the command line (client side):

mount -o udp shadowman.example.com:/misc/export /misc/local
			

When the NFS mount is specified in /etc/fstab (client side):

server:/usr/local/pub    /pub   nfs    rsize=8192,wsize=8192,timeo=14,intr,udp
