1、检查是否安装NFS必备的portmap和nfs server及client  
cnbjc0052:~ \# rpm -qa | grep portmap  
portmap-5beta-749.15  
cnbjc0052:~ \# rpm -qa | grep nfs  
yast2-nfs-client-2.13.4-0.11  
limal-nfs-server-1.1.72-0.3  
yast2-nfs-server-2.13.10-0.3  
limal-nfs-server-perl-1.1.72-0.3  
nfsidmap-0.12-16.17  
nfs-utils-1.0.7-36.29  
  
2、设置共享目录  
cnbjc0052:~ \# vi /etc/exports  
/home/sailing/eldk\_tool/ppc\_82xx \*(rw,sync,no\_root\_squash)  
  
3、重启相关服务  
cnbjc0052:/home/sailing/eldk\_tool/ppc\_82xx \# service portmap start  
Starting RPC portmap daemon                                          done  
cnbjc0052:/home/sailing/eldk\_tool/ppc\_82xx \# service nfs start  
Importing Net File System (NFS)                                      unused  
  
cnbjc0052:/home/sailing/eldk\_tool/ppc\_82xx \# exportfs -rv  
exporting \*:/home/sailing/eldk\_tool/ppc\_6xx  
  
4、查看NFS共享是否成功  
cnbjc0052:/home/sailing/eldk\_tool/ppc\_82xx \# showmount -e  
mount clntudp\_create: RPC: Program not registered  
貌似有问题  
  
5、在主机上验证NFS server功能  
cnbjc0052:~ \# mkdir /mnt/nfs  
cnbjc0052:~ \# chmod -R 777 /mnt/nfs  
cnbjc0052:~ \# mount -t nfs 150.236.70.120:/home/sailing/eldk\_tool/ppc\_82xx /mnt/nfs  
mount server reported tcp not available, falling back to udp  
mount: RPC: Program not registered  
失败，原因不明  
  
6、关闭防火墙并查看个端口信息  
cnbjc0052:~ \# iptables -A INPUT -p TCP --dport 111 -j ACCEPT  
cnbjc0052:~ \# iptables -A INPUT -p UDP --dport 111 -j ACCEPT  
cnbjc0052:~ \# rpcinfo -p 127.0.0.1  
   program vers proto   port  
    100000    2   tcp    111  rpcbind  
    100000    2   udp    111  rpcbind  
    100007    2   udp    872  ypbind  
    100007    1   udp    872  ypbind  
    100007    2   tcp    873  ypbind  
    100007    1   tcp    873  ypbind  
    100004    2   udp    911  ypserv  
    100004    2   tcp    912  ypserv  
    100024    1   udp  33762  status  
    100021    1   udp  33762  nlockmgr  
    100021    3   udp  33762  nlockmgr  
    100021    4   udp  33762  nlockmgr  
    100024    1   tcp  46628  status  
    100021    1   tcp  46628  nlockmgr  
    100021    3   tcp  46628  nlockmgr  
100021    4   tcp  46628  nlockmgr  
Rpcinfo 没看到NFS相关的服务呢？？估计是server架设有问题  
  
7、经检查确认Suse 的NFS server的启动比较特别  
cnbjc0052:~ \# /etc/init.d/nfs start  
Importing Net File System (NFS)                                      unused  
  
cnbjc0052:~ \# /etc/init.d/nfsserver start  
Starting kernel based NFS server                                     done  
  
etc/init.d/nfsserver start才是Suse上的NFS启动方式，和传统的Redhat或fedora不太相同  
  
cnbjc0052:~ \# rpcinfo   -p  
   program vers proto   port  
    100000    2   tcp    111  rpcbind  
    100000    2   udp    111  rpcbind  
    100007    2   udp    872  ypbind  
    100007    1   udp    872  ypbind  
    100007    2   tcp    873  ypbind  
    100007    1   tcp    873  ypbind  
    100004    2   udp    911  ypserv  
    100004    2   tcp    912  ypserv  
    100024    1   udp  33762  status  
    100021    1   udp  33762  nlockmgr  
    100021    3   udp  33762  nlockmgr  
    100021    4   udp  33762  nlockmgr  
    100024    1   tcp  46628  status  
    100021    1   tcp  46628  nlockmgr  
    100021    3   tcp  46628  nlockmgr  
    100021    4   tcp  46628  nlockmgr  
    100003    2   udp   2049  nfs  
    100003    3   udp   2049  nfs  
    100003    4   udp   2049  nfs  
    100003    2   tcp   2049  nfs  
    100003    3   tcp   2049  nfs  
    100003    4   tcp   2049  nfs  
    100005    1   udp    681  mountd  
    100005    1   tcp    685  mountd  
    100005    2   udp    681  mountd  
    100005    2   tcp    685  mountd  
    100005    3   udp    681  mountd  
100005    3   tcp    685  mountd  
由列表可知，NFS相关的服务已经成功启动  
  
8、再次检查共享是否成功  
cnbjc0052:~ \# showmount -e  
Export list for cnbjc0052:  
/home/sailing/eldk\_tool/ppc\_6xx \*  
cnbjc0052:~ \# showmount -a  
All mount points on cnbjc0052:  
  
cnbjc0052:~ \# mount -t nfs 150.236.70.120:/home/sailing/eldk\_tool/ppc\_82xx /mnt/nfs  
mount: 150.236.70.120:/home/sailing/eldk\_tool/ppc\_82xx failed, reason given by server: Permission denied  
cnbjc0052:/home/sailing/eldk\_tool \# id  
uid=0(root) gid=0(root) groups=0(root)  
权限不符合，当前用户已经是root了啊，那可能是文件的权限不够  
  
cnbjc0052:/home/sailing/eldk\_tool \# chmod -R 777 /home/sailing/eldk\_tool/ppc\_82xx  
chmod: changing permissions of \`/home/sailing/eldk\_tool/ppc\_82xx/usr/src/linux-2.6.24/drivers/char/hw\_random/amd-rng.c': Operation not permitted  
root不能更改普通用户的资源权限  
  
cnbjc0052 sailing/eldk\_tool> mount -t nfs 150.236.70.120:/home/sailing/eldk\_tool/ppc\_82xx /mnt/nfs  
mount: only root can do that  
普通用户无法mount  
  
cnbjc0052 sailing/eldk\_tool> chmod -R 777 ppc\_82xx  
将待共享的目录权限设置最大  
  
cnbjc0052 sailing/eldk\_tool> su  
Password:  
cnbjc0052:/home/sailing/eldk\_tool \# id  
uid=0(root) gid=0(root) groups=0(root)  
cnbjc0052:/home/sailing/eldk\_tool \#  mount -t nfs 150.236.70.120:/home/sailing/eldk\_tool/ppc\_82xx /mnt/nfs  
mount: 150.236.70.120:/home/sailing/eldk\_tool/ppc\_82xx failed, reason given by server: Permission denied  
  
为什么还是不行呢，莫非是root用户无法挂载普通用户目录下的资源？？  
  
建立新的公共目录，非普通用户home目录下，测试成功  
cnbjc0052:/ \# chmod -R 777 /opt/  
cnbjc0052:/ \# vi /etc/exports  
cnbjc0052:/ \# exportfs -rv  
exporting \*:/home/sailing/eldk\_tool/ppc\_6xx  
exporting \*:/opt  
cnbjc0052:/ \# service portmap start  
Starting RPC portmap daemon                                          done  
cnbjc0052:/ \# /etc/init.d/nfsserver start  
Starting kernel based NFS server                                                                     done  
cnbjc0052:/ \# vi /etc/exports  
cnbjc0052:/ \# showmount -e  
Export list for cnbjc0052:  
/opt                            \*  
/home/sailing/eldk\_tool/ppc\_6xx \*  
cnbjc0052:/ \# mount -t nfs 150.236.70.120:/opt /mnt/nfs  
cnbjc0052:/ \# showmount -a  
All mount points on cnbjc0052:  
\*:/home/sailing/eldk\_tool/ppc\_6xx  
\*:/opt  
150.236.70.120:\*  
  
cnbjc0052:/ \# showmount -a  
All mount points on cnbjc0052:  
\*:/home/sailing/eldk\_tool/ppc\_6xx  
\*:/opt  
150.236.236.173:\*  
150.236.70.120:\*
