NFS无法挂载解决方法

1、可以列出本地locahost的挂载，但是无法列出本地网卡IP的挂载。

[root@TM-0119 init.d]# showmount -e localhost

Export list for localhost:

/opt/Resource 192.168.16.30,192.168.16.100

[root@TM-0120 opt]# showmount -e 192.168.16.30

mount clntudp_create: RPC: Program not registered

日志如下：

Dec 8 22:14:44 TM-0119 kernel: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

Dec 8 22:15:15 TM-0119 portmap[4121]: connect from 192.168.16.100 to getport(nfs): request from unauthorized host

Dec 8 22:15:15 TM-0119 portmap[4122]: connect from 192.168.16.100 to getport(nfs): request from unauthorized host

Dec 8 22:15:15 TM-0119 portmap[4123]: connect from 192.168.16.100 to getport(nfs): request from unauthorized host

Dec 8 22:15:15 TM-0119 portmap[4124]: connect from 192.168.16.100 to getport(nfs): request from unauthorized host

解决方法

Vi /etc/hosts.allow

加上192.168.16.

即可

2、客户端无法挂载nfs

日志：

Dec 8 23:30:18 TM-0142 kernel: portmap: server localhost not responding, timed out

Dec 8 23:30:18 TM-0142 kernel: RPC: failed to contact portmap (errno -5).

解决方法：

# chkconfig portmap on

# service portmap start
