CentOS 6 NFSv3 portmap 已經不存,已經被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

過程 16.3. On the *CLIENT* side

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

mount all stuff from /etc/fstab
```
# mount -a
				
```

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

start required services

centos 5.x

chkconfig portmap on
service portmap start

centos 6

chkconfig rpcbind on
service rpcbind start

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
